- to avoid a warning in ranlib.
-
-Mon Nov 28 01:46:12 1988 Michael Tiemann (mdt at choctaw)
-

-
- * sparc.md (various places): make sure that all patterns which store
- can store using const0_rtx (i.e., make all operands to `st' %rx).
-
- * output-sparc.c (various places): changed dispatches on SYMBOL_REF
- to dispatches on CONSTANT_ADDRESS_P since we now recognize any CONST
- (and not just SYMBOL_REFs). Don't recognize special case CONST for
- output_block_move. Compiler doesn't have enough information to use
- it.
-
- * stmt.c (expand_fixup): If the control stack is nested within the
- nesting stack, then no fixup is needed. Otherwise, compiler must
- check for possible fixups between the current nesting stack and the
- nesting stack that immediately contains the control stack.

- in both the PARM_DECL and the list of types.
-
- * dbxout.c (dbxout_type): It's not a bug if a RECORD_TYPE
- has a typedef as its TYPE_NAME. That happens in C++.
-
- * Make each `asm' with operands record its source file/line
- with reg-notes. It doesn't work to emit a special note before the insn
- because the insn can be moved by loop_optimize.
- * stmt.c (expand_asm_operands): New args FILENAME, LINE.

-
- * local-alloc.c:
- `qty_...' vectors' elements for hard-reg-numbers now aren't used.
- `reg_qty' elements for hard-reg numbers now aren't used,
- and the element for a pseudo is never a hard-reg number.
- (local_alloc): No need to reset those elements.
- No need to reset elements out of range of prev block's NEXT_QTY.
- (reg_is_born, reg_is_set, wipe_dead_reg):
- Divide labor in same way for hard regs and pseudos;
- simplify using fact that locality-to-basic-block has been precomputed
- and recorded in reg_qty; avoid refs to reg_qty[HARDREG].
- (reg_is_born, wipe_dead_regs): Block-number arg no longer needed.
-
- * local-alloc.c (combine_regs): Remove old code for tying hard regs
- to pseudos; great simplification results.

- (cse_insn): Don't call find_reg_note if REG_NOTES is 0.
-
- * cse.c (cse_insn): Store modified SET_SRC even if there's a REG_EQUIV.

- if current fcn doesn't want to be inline.
-
- * cse.c (cse_insn): Speedup: instead of safe_hash, use canon_hash

- Add calls to sdbout paralleling the calls to dbxout;
- put each in the appropriate conditional {SDB,DBX}_DEBUGGING_INFO.
-
- * toplev.c (main): Delete -noreg option; it's now the default.

- within the file.

- Also braino deciding whether a spill reg can be in a group.
- Did not fix bug that it fails to test HARD_REGNO_MODE_OK,
- so it might split up an even-odd pair.

-
- * reload1.c (forget_old_reloads): Handle PARALLEL case by recursion.

- if no input files.

-
- * cse.c (fold_cc0): Stack-frame addresses are always nonzero.

-
- * decl.c (poplevel): Undo previous change with #if 0.
-

- (push_block): Copy SIZE to reg unless it's a reg or constant.
-
- * expmed.c (expand_divmod): If converting CEIL_DIV to FLOOR_DIV,

-
- * integrate.c (expand_inline_function): Don't let inline_target
- be nonzero in BLKmode.
-

- Replace return-value hard regs with INLINE_TARGET in all contexts.

-
- * 3b1 support:
- * tm-3b1.h: New file.
-

- inline fcn).
-
- * cse.c (cse_insn): Don't forget to set dest_hash_code when dest
- is a stack slot (and so its address is not being optimized).
-
- * emit-rtl.c (restore_reg_data_1): reg_rtx_no must be 1+ largest REGNO.
-
- * m68k.md (non-SImode bit-field insns): Change constraint to "o,d"

-
- * decl.c (pushlevel): New arg, nonzero means this level is for
- variables only, not for tags. All calls changed.
- (lookup_tag): Even if THIS_LEVEL_ONLY, skip variables-only levels.
- (pushtag): Define it in the first non-variables-only level.
-
- * dbxout.c (dbxout_type): Undo Mar 29 change, in the DBX_NO_XREFS case.
- So now each struct or union will contain only nameless cross-refs

- * decl.c (poplevel): Don't crash if DECL_NAME gives 0.
- * typecheck.c (comptypes): A variable array bound matches anything.

- put them in last_function_parms, and return a list of their types.
- (grokparms): Arg is now an idlist or a typelist. Do nothing if latter.

- for a parm in a parmlist.

-
- * make-cc1.com: New version from Kashtan.

- Let them handle USEs at end of scope of formal parameter copies.
-
- * integrate.c (expand_inline_function): In a new-style CALL_INSN,

- * decl.c (store_parm_decls): Among the old-style parm decls
- there can legitiately be other decls! For example, if a parm

-
- * tm-sequent.h (PRINT_OPERAND): Output (MEM (MEM (REG))) properly.

- properly; output stack-pointer as `tos'.
-
- * flow.c (find_use_as_address): Reject uses within operand 0

- (except auto-increment) is acceptable with reloading.
- Braino: Clear BADOP, not BAD.
-
- * reload.c (push_reloads): Use rtx_equal_p (via macro MATCHES)

- If operand 0 is QI or HImode, don't allow register--only `o'

- the REG_EQUAL source in its place. src_eqv's mode may be different
- from src's, so use proper mode in lookups or inserts for src_eqv.
- * Don't forget to set src_eqv_elt if src_eqv already has an elt.
- * On use_related_value for src_eqv, use src_eqv_elt.

- block, try to reuse some of the pending_stack_adjust.

- because fixup_stack_1 is called elsewhere when necessary.
-
- * reload.c (find_reloads_address): New arg is location of the MEM
- whose address is being reloaded. So we copy the MEM if it
- is one that can be shared. New arg 0 means no need to copy the MEM.
- All callers pass the new arg.

- considered volatile, because flow should now handle the code that
- can result from cse'ing them.
-

-
- * reload1.c (choose_reload_targets): Handling of reload_strict_low
- is needed for input reloads as well as output, since a strict_low_part
- operand is normally a read-write operand.
-
- * reload1.c (reload): The mode a reload needs is the wider of
- the input and output modes--just as it is in choose_reload_targets.
-
- * reload.c (find_dummy_reload): If IN and OUT have different widths
- and one of them exceeds a word, don't find any dummy reload.

-
-Tue Jan 26 04:53:16 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
-
- * reload.c (find_reloads): Now that `asm' is limited to

- BUG? Do unoffsetable mem refs using sp and fp lose?
-
- * m68k.md (movdi,movdf): Allow unoffsetable mem refs

- that do tree-walk on rtx, handle vectors of subexpressions.
-
- * loop.c (invariant_p): Likewise.
-
- * jump.c (delete_insn): Two bugs:
- If insn already deleted, return the first following nondeleted.
- Deleting a jump's label can delete NEXT. Make sure return value
- is always the first insn following INSN and not yet deleted.
-
-Sun Jan 24 02:27:49 1988 Richard Stallman (rms at frosted-flakes.ai.mit.edu)
-
- * rtl.def (ASM_OPERANDS): Change the rtl expression of an
- `asm' with operands so it looks like this for one output operand:
- (set OUTPUT (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
- 0 INPUTS INPUTCONSTRAINTS)).
- and like this for multiple outputs:
- (PARALLEL [
- (set OUTPUT0 (asm_operands:OUTPUTMODE INSNSTRING OUTPUTCONSTRAINT
- 0 INPUTS INPUTCONSTRAINTS)).
- (set OUTPUT1 (asm_operands:OUTPUTMODE1 INSNSTRING OUTPUTCONSTRAINT1
- 1 INPUTS INPUTCONSTRAINTS))])
-
- * parse.y: Change parsing of `asm' to distinguish input and output

- New variable `operand_modes' holds the machine modes of the
- operands, obtained one way for ASM_OPERANDS insns and another
- for other insns.
-
- * rtl.c (note_stores): Calling convention
- is changed: the first arg FUNCTION now receives as its 2nd arg
- 1 if clobbering, 0 if setting. Used to be the CLOBBER or SET rtx.
-
- * local-alloc.c (reg_is_set): This fn is called from note_stores;
- change its arguments.
-
- * tm-m68k.h (FIXUP_FRAME_POINTER_ADDRESSES):
- Use frame_pointer_rtx to recognize intended frame-pointer refs
- and not recognize pseudo-regs that were allocated to the frame
- pointer register.
-
- * emit-rtl.c: All refs to frame pointer use a single rtx, in
- frame_pointer_rtx. Likewise arg_pointer_rtx for the arg pointer.
- If they are the same register, these are the same rtx.
- Initialize them in init_emit.
- * rtl.h: Declare these vars.

- * reload.c (find_reloads): Handle reloading of ASM_OPERANDS.
- The number of operands can no longer be bounded.
- For example we can't always put the operands in recog_operands.
-
- New locals OPERANDS and OPERAND_LOCS point to alloca'd vectors of
- operands and their locations. New locals CONSTRAINTS and CONSTRAINTS1
- hold alloca'd vectors of constraints.
-
- Unfortunately this isn't enough; every vector with length
- MAX_RECOG_OPERANDS needs to be dynamically allocated.
- Would this be too slow? For now, a cheap "solution" is to delete
- any insn that has too many operands.

-
- * cccp.c (do_include): Output the -M info after searching the dirs;
- include the actual dir name. Don't generate "./" for current dir.

- If possible, find an input reload
- and an output reload that can be turned into one input-output reload.

- and reload_in both zero. This is called from find_reloads.
-
- * reload1.c (reload, choose_reload_targets): Ignore inoperative
- reloads.

- Handle %$ in both old and new PRINT_OPERAND.
- Define CPP_PREDEFINES.
-
- * ns32k.md: Merge some features from Jan Stein's port:
- strict_low_part insns, smart output of booleans with small
- constant args, acbd insns generalized for other increments.
- Use %$ wherever there is an explicit immediate.
- Fix shortcomings of adjsp insns: use adjspd in general,
- and use adjspb in all the cases that allow it.
- Don't bother explicitly clearing CC_REVERSED.
- For tstsf/tstdf, output the floating-zero constants

-
-Sun Jan 17 04:37:20 1988 Richard Stallman (rms at frosted-flakes)

-
- * decl.c (finish_decl): Error if auto var's size isn't known.

-
- * decl.c (build_struct): Reform code to detect erroneous bit-fields.
- All such errors are now detected here.
- Promote bit-fields to int if appropriate.
- If traditional, make all int bit-fields unsigned.
- Set DECL_ALIGN for members that are not bit-fields.
-
- * decl.c (grokfield): Don't set DECL_ALIGN here.
-
- * stor-layout.c (layout_decl): Don't promote the type of a bit-field.
- Use TREE_PACKED to distinguish a bit-field.
- Don't check the width because build_struct did that.
-
- * m68k.md (cmpm): Reject if either operand (address) is a constant.
-
-Tue Jan 12 15:11:20 1988 Richard Stallman (rms at frosted-flakes)
-
- * cse.c (canon_reg): Never replace ANY hard reg from reg_rtx
- because that could alter the machine mode.

-
-Mon Jan 11 13:15:45 1988 Richard Stallman (rms at frosted-flakes)

-
-Sun Jan 10 14:52:42 1988 Richard Stallman (rms at frosted-flakes)
-
- * reload1.c (reload): basic_block_needs (new vector) gets 1
- for each basic block that needs a reload.
- * reload1.c (spill_hard_reg): Don't spill pseudos that are
- confined to a basic block which has no need for any reloads.
- * reload1.c (reload): Each cycle that any element of basic_block_needs
- changes from 0 to 1, must re-spill all previously spilled regs.
-
- * regclass.c (record_address_regs):
- Skip the charging of ICOST if it is 0.
-
- * flags.h, toplev.c: New flag -fvolatile.
- * typecheck.c (build_indirect_ref): If flag_volatile,
- every INDIRECT_REF is marked with TREE_THIS_VOLATILE.
-
- * fold-const.c (fold): Test in TRUTH_NOT_EXPR case was backward.
- Also result type is always `int'.
-
-Sat Jan 9 04:16:11 1988 Richard Stallman (rms at rice-krispies)
-
- * flags.h (flag_traditional): New flag.
- * toplev.c: recognize -ftraditional and -traditional.
- * parse.y (yylex): If flag_traditional, don't recognize

- hard reg for each allocno. If so, try it first (new call to find_reg).
-
- * global-alloc.c (find_reg): New arg PREFREG specifies reg to try
- first.
-
- * decl.c (build_struct): if :0 bit field at the end, round the
- structure size to multiple of EMPTY_FIELD_BOUNDARY.
-

- and should be == -1.
-
- * reload1.c (reload_as_needed): Fix invalid optimization deleting
- the previous store into a pseudo-reg that feeds an input-reload.
- It is not safe because a later insn may look in the pseudo's stack
- slot for the value. Delete the store only if we can eliminate the
- pseudo entirely or if the current insn stores a new value there.
- Also verify that reload_in[j] is a REG.
-
- * reload1.c (reload_as_needed): When doing an input reload from a
- pseudo that was stored by the previous insn (not as a reload),
- redirect the previous insn into the reload register, if this lets
- us eliminate the pseudo entirely.
-
- * reload1.c (reload_as_needed): In both of the above cases, it's
- impossible to prevent a stack slot since one was already assigned,
- so don't alter reg_n_refs. Instead, set reg_renumber to record
- that this pseudo did get a hard reg.
-
- * stmt.c: Set `volatil' in pseudo-regs for the user's variables.
-
- * jump.c (delete_insn): Do nothing if insn already deleted.
-
- * tm-sun{2,3}.h: #define STRUCTURE_SIZE_BOUNDARY 2
- for compatibility with Sun PCC. Note that 4.3 vax PCC
- does not want this.
-
- * fold-const.c: Replace truncate_unsigned with force_fit_type
- which truncates unsigned types and sign-extends signed types.
-
- * expr.c (do_jump): emit_queue before outputting the jump insns
- that use the comparison.
-
- * stmt.c: Error message for any goto that jumps into a
- binding contour that restores a stack level.
-
- TREE_PACKED (label) means label was defined inside
- such a binding contour that is now exited. Using such a label
- is an error.
-
- TREE_ADDRESSABLE (label) means label was used from a place
- outside all such binding contours. If this is 1 when
- TREE_PACKED is set to 1, it is an error.
-
- Any other invalid goto must have a fixup. fixup_gotos detects
- such invalid gotos. fixup_gotos takes a second arg, which
- is the first insn of the contour now being exited.
-
- * GNU C version 1.17.

-
- * rtl.def (DEFINE_DELAY): Change description to describe annulling.
-
- * genattr.c (main): Write out definitions for annulling, if present.
-
- * genattrab.c (expand_delays): Build internal attributes for
- which insns can be annulled in a delay slot.
- (gen_delay): Validate number of elements in DEFINE_DELAY list.
- (write_eligible_delay): Write out routines for validating annulled
- insns as well as those in normal delay slot.
- (main): Call write_eligible_delays to output annulling information,
- if it exists for this machine.
-
- * out-m68k.c (not_sp_operand): New function.
- * m68k.md (andsi3): Don't allow sp as ourput to avoid reload
- inefficiency.
-
- * calls.c (struct arg_data): Delete field STORED; add fields
- PASS_ON_STACK and SAVE_AREA.
- (prepare_call_address): Static chain value can't have QUEUED.
- (expand_call): Rework to support additional calling sequence options.
-
- Major changes include:
- Call FUNCTION_ARG_PASS_BY_REFERENCE to determine whether an
- object should be passed by invisible reference.
- Handle arguments passed both on stack and in a register; this can be
- used to allow arguments that are hard to compute directly into
- registers to be passed.
- Support option (ACCUMULATE_OUTGOING_ARGS) where the largest amount
- of stack for outgoing arguments is computer and pushed during the
- function prologue. Stack space usage is tracked and any location
- that would need to be reused will be saved and restored.
- If preallocating arg block, compute address where each arg will be
- placed and pass it as target to expand_expr.
-
- Other changes:
- Use virtual regs to see if structure value address isn't stable.
- If inlined, return TARGET if TARGET and TEMP are equivalent.
- UNNAMED_ARGS_IN_REGISTERS is redundant with the NAMED parameter to
- FUNCTION_ARG and has been deleted.
- Use virtual_outgoing_stack_rtx instead of FIRST_PARM_CALLER_OFFSET.
- Use locate_and_pad_parm to compute any needed padding for argument.
- If REG_PARM_STACK_SPACE is defined, allocate backing stack locations
- for args passed in registers; these are not included in the length
- of stack space required unless OUTGOING_REG_PARM_STACK_SPACE is also
- defined.
- When precomputing register parameters, can stop computation when we
- obtain any rtx, not necessarily a register.
- No longer need code to protect data written below bottom of stack;
- this is taken care of by preexpanding calls in argument.
- target_for_arg no longer needed; its function is performed by
- store_one_arg.
- Always copy function return result to our target since they cannot
- possibly be the same.
- (target_for_arg): No longer used.
- (store_one_arg): Save and restore in-use argument list location.
- Support args passed both in register and on stack.
- No need for explicit code for preallocated area; now pass location
- as target to expand_expr; only copy if result in different place.
- Put sequence point after expanding one value.
-
- * cse.c (struct write_data): Add bit to indicate stack pointer changed.
- (canon_hash): Allow recording of stack pointer.
- (cse_insn): Indicate stack pointer invalidated by subroutine calls.
- Pass stack push and pop operations to note_mem_written.
- Process stack pointer assignment as normal operation.
- Finish change of April 7th that excludes ap and fp from being marked
- as clobbered by calls. Also exclude sp; if it is clobbered by a
- call, an explicit CLOBBER will be written.
- (note_mem_written): Look for adjustment of stack pointer.
- (invalidate_from_clobbers): Invalidate stack pointer, if required.
-
- * emit-rtl.c (gen_inline_header_rtx): Add field for outgoing args size.
- (copy_rtx_if_shared): Check for any virtual register instead of frame
- or argument pointer.
- (init_emit): Start normal pseudos after virtual pseudos.
- Copy the unique virtual regs into regno_reg_rtx.
- (init_emit_once): Incoming and outgoing static chain can be the same;
- inlining of nested functions won't need the distinction.
- Create unique copies of virtual registers.
-
- * explow.c (memory_address): Don't worry about refs to fp or ap;
- force_reg knows how to handle them correctly.
- (fix_lexical_addr): Moved to function.c
- (adjust_stack, anti_adjust_stack): Do nothing for adjustment of zero.
- (allocate_dynamic_stack_space): New function copied from
- expand_builtin. Handle STACK_POINTER_OFFSET via
- virtual_stack_dynamic_rtx. When STACK_POINTER_OFFSET is defined,
- perform alignment by always reserving a multiple of STACK_BOUNDARY
- stack bits. This avoids concern about whether sp itself or the top of
- stack needs to be aligned; if we start with an aligned stack, we keep
- it aligned.
- (round_push): Use ADD and AND rather than DIV and MULT.
-
- * expr.c (init_expr): Initialize some more vars.
- (push_block): Use virtual_outgoing_args_rtx so don't need
- STACK_POINTER_OFFSET here.
- Merge extra and size more efficiently; no need to call force_operand
- since memory_address is called.
- (emit_push_insn): Pass type for FUNCTION_ARG_PADDING.
- Use REG_PARM_STACK_SPACE instead of FIRST_PARM_CALLER_OFFSET.
- To see if must copy address, check if it is a virtual register that
- will be mapped to sp; only need check if not accumulating space
- space for outgoing parms.
- Ignore EXTRA if argument block has already been allocated.
- (emit_library_call): Major rework to support calling sequences similar
- to expand_call in calls.c, but only support a very small subset of
- the conventions; abort if something outside our subset occurs.
- Abort if incorrect mode is passed; we can't convert here since we don't
- know the signedness.
- (store_field): Check for virtual registers instead of hard registers
- when seeing if stable.
- (safe_from_p): Location in outgoing stack area is known to be safe.
- (expand_builtin, BUILT_IN_ALLOCA): Use allocate_dynamic_stack_space.
-
- * expr.h: Define current_function_outgoing_args_size and
- locate_and_pad_parm; delete definition of get_structure_value_addr.
- (ARGS_SIZE_RTX): Always return a valid operand.
- (ARGS_SIZE_TREE): New macro.
- (FUNCTION_ARG_PADDING): Accept MODE and TYPE like other
- FUNCTION_ARG_... macros.
- (FUNCTION_ARG_BOUNDARY): Provide default for new macro.
- (MUST_PASS_IN_STACK): New macro.
- (allocate_dynamic_stack_space): New function.
- * tm-3b1.h, tm-3b1g.h, tm-apollo68.h, tm-crds.h, tm-mot3300.h:
- Change definition of FUNCTION_ARG_PADDING to use TYPE instead of SIZE.
-
- * function.c (current_function_outgoing_args_size): New var.
- (arg_pointer_save_area, virtuals_instantiated): Likewise.
- (invalid_stack_slot): No longer used.
- (push_function_context, pop_function_context): Save and restore
- outgoing args size and arg pointer save area.
- No longer save or restore invalid_stack_slot.
- (pop_function_context): Set up variables whose value is constant
- throughout rtl generation.
- (get_frame_size): No longer adjust by STARTING_FRAME_OFFSET.
- (assign_stack_local): Use virtual_stack_vars_rtx instead of fp
- until virtuals have been instantiated, then use fp.
- Remove reference to obsolete invalid_stack_slot.
- Can no longer be called with size == 0.
- (assign_outer_stack_loc): Use virtual_stack_vars_rtx instead of fp.
- Remove references to obsolete invalid_stack_slot.
- Push to obstack of containing function when allocating rtx.
- (put_var_into_stack): Only switch obstacks around making of
- queue entry.
- Replace call to parm_stack_loc with reference to info in proper
- function.
- (fixup_stack_1): Handle any virtual register instead of handling
- just fp.
- (instantiate_virtual_regs, instantiate_virtual_regs_1): New functions.
- (use_variable, use_variable_after): Check for virtual register
- instead of checking against ap and fp.
- (parm_stack_loc): Function deleted.
- (assign_parms): No longer need internal_arg_pointer.
- Accept SECOND_TIME argument that suppresses rtl generation and
- assignments to DECL_RTL. Used by integrate.c to recompute vars.
- Don't use FIRST_PARM_OFFSET here; use virtual_incoming_args_rtx.
- Replace test for nonstable incoming arg pointer.
- If structure value address is treated as the first argument, add
- it into the list of arguments; this means we can have a RESULT_DECL
- in with the PARM_DECL's.
- DECL_OFFSET is no longer needed by integrate.c.
- Handle args passed by invisible reference.
- Support new macro, SETUP_INCOMING_VARARGS, to save all registers used
- for args including and beyond those for the current arg. Used for
- non-ANSI varargs.
- Pass locate_and_pad_parm data it needs to handle reg->stack boundary
- if register parameters have assigned stack space.
- If we received the function's incoming structure pointer as a
- normal argument, update DECL_RTL of DECL_RESULT.
- Round total argument size if required; similarly, always use at
- least REG_PARM_STACK_SPACE bytes if defined.
- (locate_and_pad_parm): Do not need PARM.
- Major rework to do much of the job of aligning and padding stack
- location. Now a void function wich is passed pointers to struct
- args_size vars that are set to the argument position, size, and
- initial offset.
- Accept flag denoting if a parm was passed in a register and also
- the current function declaration.
- If register parameters are assigned stack locations and there is a
- minimum required size for the area assigned to register parameters,
- pad the stack position when a parameter not assigned to a register
- is encountered.
- Remove redundant code in MAX_PARM_BOUNDARY case.
- (lookup_static_chain): Use virtual_stack_vars_rtx instead of fp.
- (fix_lexical_addr): Move from explow.c.
- If referencing variable that lives in the incoming argument area
- of its parent and a separate ap is required, allocate a save area in
- the parent for it and use it here. If no separate ap is require,
- compute offset between ap and fp.
- (trampoline_address): No need to push obstacks here.
- (init_function_start): Initialize new vars; delete obsolete vars.
- (expand_function_start): Don't need to handle case where incoming
- structure return address is passed as hidden parameter here; now done
- completely in assign_parms.
- (expand_function_end): Save ap if a save area was made for it.
- Set REG_FUNCTION_VALUE_P when copying address of returned
- structure.
- Be consistent in use of FUNCTION_... macros vs. hard_function_value.
-
- * function.h (outgoing_args_size, arg_pointer_save_area): New fields.
- (invalid_stack_slot): Obsolete, deleted.
-
- * integrate.c: Major rework and simplification.
- Split up vars into two classes. Those used for expand_inline_function
- and children are now part of struct inline_remap. Most of the others
- are for save_for_inline and its children.
- (function_cannot_inline_p): The only type of arguments that will
- cause us to reject inlining are variable-sized arguments; also
- reject functions that return variable-sized objects.
- For now, don't inline a nested function. We'll support this shortly.
- Use current_function_returns_pcc_struct instead of duplicating test.
- (save_for_inline): No need to set TREE_VOLATILE for parms.
- Save outgoing args size in header.
- Use unique copy of virtual reg rtx's.
- Handle any required fixups for INSN_LIST forward-references.
- Don't bother resetting dead static vars when we are done.
- Need not save current_function_pretend_args_size.
- (copy_for_inline): First copy all insns, then all REG_NOTES to avoid
- problems with forward references.
- (struct inline_remap): Move all previously-static vars used by
- expand_inline_function and children into this structure. This avoids
- potential problems due to recursive calls to expand_inline_function.
- (expand_inline_function and children): Allocate a struct inline_remap
- and pass to all children.
- (expand_inline_function): Rework parameter handling by looking at
- DECL_RTL and using it to determine what types of mappings need to be
- done. Support objects passed by invisible reference. Put any
- constant memory addresses into const_equiv_map. parm_map is no longer
- used.
- Likewise for the return value: consult DECL_RTL (DECL_RESULT)).
- Don't allocate space for called function's frame until referenced.
- No longer need special handling for insn following CALL.
- Ignore USE whose argument has REG_FUNCTION_VALUE_P true.
- Ignore setting function register if we don't have a mapping for it
- (e.g., we are ignoring the result of the call).
- Look at new SET_SRC for constant equivalences. Some new ones may
- have resulted from constant folding.
- Pass both new and old rtx to try_constants.
- Discard NOTE_INSN_DELETED notes.
- Copy insns first, then REG_NOTES, to avoid problems with forward refs.
- (copy_parm_decls): Compute new address of parameter using the
- constant equivalence map, which will contain the remapping of
- the frame and argument pointer.
- (copy_decl_tree): Likewise.
- (copy_rtx_and_substitute): Handle references to frame and argument
- pointers by allocating a space equal to the size of the frame and
- incoming arguments, respectively, and setting a pseudo to point to
- the start of each area. Set up an equivalence in CONST_EQUIV_MAP
- between fp or ap and the actual address. Return the pseudo.
- Don't need to deal with possibility of (SUBREG (CONST_INT)) since
- we are only replacing register with other registers here.
- No longer need to special-case PLUS and MEM; subst_constants will do
- this work.
- Update detection of sets of ap and fp.
- (try_constants, subst_constants): Accept old and new rtx. They will
- be isomorphic, with only register numbers changed. Use old rtx to
- look up register in CONST_EQUIV_MAP and new rtx for substitution.
- Correctly handle SUBREG of CONST_INT and CONST_DOUBLE.
- Fix typos in handling of PLUS.
- (access_parm_map, copy_address): Delete functions.
- (try_fold_cc0): Handle both compare and test.
- (fold_out_cnst_cc0): Rework to simplify and remove dubious cases.
- (output_inline_function): Call assign_parms to perform any needed
- setups.
- Need not restore pretend arg size (will be computed by assign_parms).
- Restore outgoing argument size.

-
- * rtl.h (OUTGOING_ARGS_SIZE): New field in INLINE_HEADER.

-
- * rtlanal.c (rtx_equal_p): Update comment on use of
- REG_FUNCTION_VALUE_P.
-
- * stmt.c (expand_goto): Just restore fp; non-local goto handler
- will restore ap if needed.
- (expand_return): Don't use STARTING_FRAME_OFFSET here.
- (expand_end_bindings): Adjust fp in nonlocal-goto handler. If needed,
- reload ap from its save area in the frame; allocate save area if none.
- (expand_decl): Use new function allocate_dynamic_stack_space.
-
- * toplev.c (rest_of_compilation): Instantiate virtual registers.
- Clear rtx_equal_function_value_matters immediately after possibly
- saving current routine for inlining.
-
- * stupid.c (stupid_life_analysis): Don't try to allocate virtual
- registers (which don't exist any more).

-
- * expr.c (safe_from_p): If EXP has some rtx, just check it.
- Handle TREE_LIST, RTL_EXPR, and WITH_CLEANUP_EXPR.
- Note that CALL clobbers memory and hard registers.
- Look at enclosed object for SUBREG, but SUBREG of a hard reg is unsafe.

- Alignment is no restriction if it matches BIGGEST_ALIGNMENT.
- Always do the real work in SImode if couldn't use MEM.
- (extract_bit_field): Likewise.
-
- * combine.c (subst): Handle (sign_extend:M (subreg (sign_extract:M)))
- on big-endian machine like corresponding zero_extend case.
-
- * combine.c (try_combine): Use rtl_equal_p instead of == when
- testing for sources and destinations that match.
-
- * pyr.md (bitw recognizer): Set CC_NO_OVERFLOW.
-
-Thu May 3 13:03:02 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-

- * objc-parse.y (program): Call objc_finish at the end.
-
- * Changes from Matthew Self (mself@next.com):
-
- * objc-parse.y: Since objc-parse.y was so out of date with
- respect to c-parse.y, I started over with c-parse.y and
- reintegrated the Objective-C modifications. Now that
- Objective-C is working I hope that objc-parse.y will be kept
- more up to date.... I did not re-integrate the lexer since I
- don't have gperf working. I simply cut and pasted what
- Stallman had in objc-parse.y. Someone with access to gperf
- should re-generate this stuff.
-
- * objc-actions.c (comp_method_with_proto,
- comp_proto_with_proto): Stallman's change to use the
- functions end_temporary_allocation and
- resume_temporary_allocation is incorrect, since it always
- leaves allocation temporary, whether it was before or not.
-
- Perhaps the push and pop functions would do the trick....
-
- * objc-actions.c (get_arg_type_list): Use new function
- groktypename_in_parm_context.
-
- * objc-actions.c (_OBJC_SELECTOR_REFERENCES_decl,
- _OBJC_SELECTOR_REFERENCES_id): Removed.
-
- * objc-actions.c (synth_module_prologue): Eliminated code to
- forward declare the selector references array.
-
- * objc-actions.c (init_objc_symtab): Eliminated code to
- initialize "refs" field in objc_symtab structure (which is
- now vestigial).
-
- * objc-actions.c (build_selector_translation_table): Rewrote.
-
- * objc-actions.c (build_selector_reference): New routine.
-
- * objc-actions.c (build_message_expr, build_selector_expr):
- Use new routine.
-
- * config/tm-next.h (GO_IF_INDEXABLE_BASE): Don't use pc
- relative addressing for LABEL_REF's. Since branch tables are
- in the const section, we treat LABEL_REF's like SYMBOL_REF's
- here. Otherwise invalid addresses were being generated.
-
- * config/tm-next.h (CASE_VECTOR_PC_RELATIVE, CASE_VECTOR_MODE):
- Use absolute branch tables rather than relative ones.
-
- * config/tm-next.h (ASM_OUTPUT_MAIN_SOURCE_FILE_END): Output
- an N_SO symbol with no name to mark the end of the module.
- This is needed to support scattered loading on the NeXT.
-
- * config/out-next.c (handle_pragma): Call to xrealloc had wrong args.
-
- * configure: Entry for NeXT must set out_file to out-next.c.
-
- * config/out-next.c: Typo: "flags" -> "flags.h"
-
- * config/tm-next.h (LIB_SPEC): Brought up-to-date. There
- are probably more changes needed here.
-
- * c-decl.c (pushdecl_top_level): New function. This was
- copied from an older version of g++.
-
- * c-decl.c (init_decl_processing): Make alloca first arg sizetype.
-
- * c-decl.c (groktypename_in_parm_context): New function.
-
-Mon Jan 28 07:07:01 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * loop.c (loop_reg_used_before_p): Don't use INSN_LUID since INSN
- might have been made by loop.c for an outer loop.
-
- * loop.c (move_movables, strength_reduce): Replace register references
- in REG_NOTES as well as PATTERN.
-
- * loop.c (strength_reduce): Call maybe_eliminate_biv twice, not
- three times.
- (maybe_eliminate_biv): Don't abort if elimination fails even though
- we thought it wouldn't. This can happen if certain insn patterns
- aren't valid.
- (maybe_eliminate_biv_1): Ensure that we do not change the insn at
- all if all the required changes can't be done.

- * dbxout.c (dbxout_type): Get rid of conditional; can always use these.
-
- * cccp.c (lookup_import): Do return -2 if file found.
- (main): Handle `.m' suffix like `.S'.
-
- * configure (m68k/next): Use out-next.c.
-
- * WORD_SWITCH_TAKES_ARG and SWITCH_TAKES_ARG now give # of args.
- * gcc.c (struct switchstr): New field `args' replaces `part2'.

-
-Sat Jan 26 1990 Ron Guilmette (rfg at ncd.com)
-
- * README.DWARF: updated to reflect changes to dwarfout.c, the
- inclusion of dwarf.h (and its changes) and the fact that the
- DWARF support is no longer directly tied to the DG versions of
- GCC.
-
- * dwarfout.c: included a patch (provided by Ray Essick) to allow
- dwarfout.c to properly get a value for MAXPATHLEN even on (old)
- System V.3 systems.
-
- * dwarfout.c: added support for long long types (as suggested by
- Ray Essick).
-
- * dwarfout.c: added support for the AT_comp_dir attribute. Also,
- as part of this change, the name of the compilation directory is
- no longer placed into in the .sources section.
-
- * dwarfout.c: added support for the AT_addr_ranges attribute.
-
- * dwarfout.c: added support for the AT_prototyped attribute.
-
- * dwarfout.c: added support for the AT_src_info attribute. Also,
- as part of this change, there is no longer a "special" entry
- at the start of the .srcinfo section for each compilation unit,
- and the contents of the "special" final entry in the .srcinfo
- section have changed (to { -1, -1 }).
-
- * dwarfout.c: modified to allow additional GNU DWARF extensions
- to be generated whenever the corresponding extended attribute
- codes are defined (presumably within a modified dwarf.h file).
-
- * dwarfout.c: use the section names .srcinfo and .sources rather
- than .finfo and .files. The additional specificity is warranted
- because the DWARF information may someday include information
- about object files as well as source files.
-
- * dwarfout.c: fixed a bug where a type attribute was being generated
- for functions and function types even when the return type was
- void. "Standard" dwarf says that if the return type for a function
- or function type is void then no type attribute should be generated
- for the corresponding DIE.
-
-Sat Jan 26 04:22:08 1991 Michael Tiemann (tiemann at cygnus.com)

- be represented.
-
-Thu Jan 24 21:18:15 1991 Richard Stallman (rms at mole.ai.mit.edu)
-
- * config: Conditional for setting $os was backward.

- of assuming 0.
-
-Mon Dec 31 08:09:10 1990 Michael Tiemann (tiemann at cygnus.com)
-
- * cplus-typeck.c (c_expand_return): Handle case when we try
- to return a void value (such as a void function call) in a
- function returning void, and there are cleanups to run.
-
-Sun Dec 30 21:08:32 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * tm-a29k.h (TARGET_VERSION): Can't use target_flags since we can
- be called from gcc.c.
-
- * tm-rs6000.h (REG_ALLOC_ORDER): Put r12 after r13; it might be
- holding a DImode value and so might be very expensive (we won't
- worry about TImode).
-
- * rs6000.md (subtract patterns): Fix incorrect operand number in %I.
- (movti): Disallow indexed memory operands.
-
- * out-rs6000.c (print_operand, case 'm'): Fix typo.
- (includes_rshift_p): Correctly compute mask.
-
- * out-a29k.c (output_operand): Add missing parentheses.
- (print_operand): Replace if/then/else structure with switch statement.
-
- * a29k.md (beq, bne): Try to use NE test whenever possible; it
- will produce better code if we have bit-tests.
-
-Sun Dec 30 12:02:03 1990 Michael Tiemann (tiemann at cygnus.com)
-
- * tm-sparc.h (PRINT_OPERAND): Put 'R' case before REG so that it
- takes when 'R' is passed in as CODE. Also, handle 'B' letter.
-
- * sparc.md: (pattern for converting DFmode to SImode): Second
- argument to `output_asm_insn' should be `operands', not zero.
- (tablejump): The jump insn is "jmp", not "jump".
- (gen_fixtruncdfsi2): operands[2] should get the pseudo, not
- operands[3] (which is nonexistent).
- (call): Fix typo which had %o7 being emitted as %o.
- (various patterns): Fixed places where match_operand had the wrong
- operand number.
-
-Sat Dec 29 17:27:00 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * sparc.md: cc_status no longer handles condition code updates.
- Instead, condition codes are explicitly set and used via
- hard register 0. Special attributes specific to condition codes
- (such as whether conditional branches should test the integer or
- floating-point condition codes, or that the condition codes cannot
- be tested for a condition which would test the overflow bit) are
- handled by encoding the attribute in the mode for the condition
- code register.
- (type attributes): type "unary" insns have one input operand (1)
- and one output operand (0)
- type "binary" insns have two input operands (1,2) and one output (0)
- type "compare" insns have one or two input operands (0,1) and no output
- type "move" and type "arith" have been deleted.
- (prescan attribute): Deleted. Machine description now puts
- floating-point zero in registers when needed.
- (use_cc attribute): Deleted.
- (fpcc define_delay): No longer depend on "use_cc" attribute.
- Also, fpcc delay characteristics hold for "fpcc" type insns.
- (cc attribute): Deleted.
- (cmpxx patterns): Now written as `define_expand's so we can stow
- away operands. When the pattern that will use the results of the
- conditional test is emitted, it can use these operands to figure
- out the right way to emit the compare.
- (bcc patterns): Rewritten to emit comparison (based on stowed-away
- info) before emitting branch.
- (scc patterns): Handle all the cases with branch-free code.
- Added new pattern to recognize (x + (i == 0)).
- (movsi pattern recognizer): Split into two patterns so that e.g.
- "(set:SI (mem:SI ...) (const_int 5))" is never considered valid.
- Instead this has to be a two-insn sequence.
- (mov{hq}i pattern recognizers): Ditto.
- (movstrsi): Force operands[2] out of memory if it was in memory.
- ({zero,sign}_extendXY): Now written as `define_expand's instead of
- `define_insn's for more accurate machine modeling.
- Added new pattern to optimize bit-field compares.
- (floatsisf2 patterns): Delete redundant setting of "in_call_delay"
- attribute.
- (fix_trunc{sf,df}si2 pattern): Use clobberable register in which
- the conversion can take place. Used to use %f30,%f31.
- ({add,sub}di3 pattern): Put explicit clobber of (reg 0) in the
- pattern.
- (negdi2 pattern): Ditto.
- Added new patterns to handle merging of addition/subtraction with
- condition code testing (with (reg:CC_NOOV 0)).
- ({and,ior,xor}cbsi3 pattern): Obsolete. Deleted.
- Added patterns to represent setting of condition codes in addition
- to performing logical operations.
- ({neg,abs}df2 pattern): Use `R' print letter to overcome the need
- to use a C action instead of a simple template.
- (ash{l,r}{hi,qi}3): Define patterns for shifts on sub-SImode
- operands.
- (jump pattern): Use `*' print code to obviate the need for a C
- action when a template can do.
- (tablejump pattern): Ditto, with `^' code as well.
- Deleted `define_split's that were used to handle mem-mem moves in
- the case of PIC generation. Since all move insns are emitted and
- maintained as SPARC-valid insns, these should no longer be needed.
- (various patterns): (HI ...) is spelled (HI:SI ...). Also, use
- `gen_lowpart' instead of building subregs directly.
- New `define_split's were added to split scc insns into simpler
- components which have single-insn templates.
- Fixed a return peephole when returning a SFmode value (it was
- missing the "ret"!).
- Lots of complicated peepholes that brought cc testing and
- arithmetic operations together were deleted. This is because the
- combiner should now handle all these cases.
-
- * out-sparc.c (sparc_compare_op{0,1}): New global variables.
- Used to hold the operand(s) to compare insns in lieu of emitting a
- compare.
- (reg_or_cc0_operand): Deleted.
- (normal_comp_operator): New function.
- (cc_arithop): Now returns 0 for PLUS and MINUS.
- (cc_arithopn): Now returns 0 for XOR.
- (gen_compare_reg): New function.
- (sparc_address_cost): Simplified because it turns out it doesn't
- matter what is returned for illegitimate addresses.
- (hard_regno_mode_ok): Updated to use these new #defines.
- (C_MODES): New #define, for condition code modes.
- (S_MODES): Ditto, for single-word (and smaller) quantities.
- (D_MODES): Ditto, for double-word (and smaller) quantities.
- (T_MODES): Ditto, for tetra-word (and smaller) quantities.
- (SF_MODES): Ditto, for SFmode quantities.
- (DF_MODES): Ditto, for SF_MODE, DFmode, SCmode, etc.
- (TF_MODES): Ditto, for DF_MODE, TFmode, DCmode, etc.
- (output_floatsi{df,sf}2): Greatly simplified.
- (output_pic_sequence,output_pic_sequence_2,fp_zero_hook,
- output_tail_call): Turned off.
-
- * tm-sparc.h (ASM_SPEC): Pass `-k' to assembler if compiling PIC.
- (WORDS_BIG_ENDIAN): Define as 1, not 0.
- (FIXED_REGISTERS): %f30 and %f31 are now allocatable.
- (REG_CC0_RTX, CC0_REGNUM): Deleted.
- (EXTRA_CC_MODES): New modes CC_NOOVmode and CCFPmode. The former
- is for when the overflow bit it not to be tested; the latter is
- for when the condition is sitting in the floating point unit.
- (SELECT_CC_MODE): New macro.
- (FINAL_PRESCAN_INSN): Deleted.
- (CC_* macros): Deleted.
- (PRINT_OPERAND_PUNCT_VALID_P): New valid chars are '#' (for
- whether to print a noop or not), '*' (for whether to print a ",a"
- or not), and '^' (for whether to emit code for PIC branch or not).
- (PRINT_OPERAND{,_ADDRESS}): Replace calls to fprintf by calls to
- fputs where that is convenient.
-
- * expr.h, cplus-dbxout.c: #ifdef BYTES_BIG_ENDIAN should be #if.
-
- * reload.c (struct replacement): Add new field subreg_loc.
- (push_reload): If reloading SUBREG_REG of a paradoxical SUBREG,
- store the location of the SUBREG in subreg_loc in REPLACEMENTS.
- (push_replacement): Initialize subreg_loc.
- (subst_reloads): Don't produce nested SUBREGs; use subreg_loc.
-
- * regclass.c (regclass): Handle (set X (op CONST Y)) properly when
- the modes of operands 0 and 1 are different.

- If profiling, leave some space after `gcc_compiled.'.
- * tm-m88k.h, tm-sparc.h, tm-sun386i.h (ASM_IDENTIFY_GCC): Deleted.
-
- * reload1.c (emit_reload_insns): Set reg_reloaded_contents, etc, here.
- (choose_reload_regs): Not here--except for reg_has_output_reload.
-
- * c-parse.y (nested_function, notype_nested_function):
- Use compstmt for body, not compstmt_or_error.
-
- * Makefile.in (install-headers): Use basename on
- * stupid.c (stupid_mark_refs): Really do mark clobbered hardreg
- live before the insn.
-

-
- * tm-v88r32.h (LIB_SPEC): Goes here rather than in xm-v88r32.h.

- (perform_*): Define each if not already def.
-
-Tue Dec 25 17:31:17 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * loop.c (get_condition): Rework scan that looks for sets of things
- being compared to allow intervening insns; check to ensure that
- they don't set something that we need. Return 0 if the best we can
- do is find something whose mode is in class MODE_CC.
-
- * calls.c (emit_call_1): RETURN_POPS_ARGS now gets the length of
- arguments on the stack and returns the number of bytes popped by the

-
- * m88k.md, out-m88k.c, tm-m88k.h (swapped cmpsi): Don't rely on

- improve code that looks at resources. Now takes about 0.5% of
- compilation time.
- (fill_simple_delay_slots): Always call mark_target_live_regs with an
- active insn; currently being called with a CODE_LABEL.

-
- * cplus-decl.c, cplus-search.c, gcc.c, objc-actions.c, rtl.c, stmt.c,

-
- * local-alloc.c (combine_regs): No need to see if suggested hard reg

- equivalent for the two threads we are looking at.
-
- * combine.c (try_combine): Fix typo in loop over I1 with PARALLEL
- body. Also, don't test HARD_REGNO_MODE_OK for hard registers we are
- thinking about combining. This screws up using registers to
- represent the condition codes, and probably doesn't save anything in
- the general case.
-
- * expmed.c (expand_and): Comment says that result is always stored
- in target, so the code now does this.
-
-Sat Dec 15 18:09:46 1990 Michael Tiemann (tiemann at cygnus.com)
-
- * loop.c (get_condition): Try a little harder to find the setter of
- the register used in a conditional test. On the SPARC it is vital
- to either find the setter of the register used for the condition
- codes or for this function to return 0. Also, have test for
- non-NULL, matching `set' govern both normal and reversed cases of
- comparisons.
-
- * jump.c (jump_optimize): When moving USE insns from before jumps to
- after BARRIERs, put the label for the redirected jump after the
- BARRIER instead of just before the PREV_INSN of the original target.
- This gets around problems when there are NOTEs between the BARRIER
- and the original target.
-
-Sat Dec 15 10:16:29 1990 Michael Tiemann (tiemann at cygnus.com)

- [reg].
- (adddf,subdf,negdf): Simplify output routines using 'R' as an
- output letter.
- (tail_call): Turn this off. It is never used, and it depends on
- routines which are about to become broken.
- (various places): Add USE_CC attribute where appropriate.
- (various places): Change (use (reg:SI 0)) to (clobber (reg:SI 0))
- and delete CC_CLOBBER attribute from the pattern.

- (sparc_address_cost): Simplified, since the value returned is not
- used if the address is not legitimate.

- SUBREGs explicitly.
- (make_f30_contain_zero): Deleted.
- (output_tail_call): Turned off.
- * tm-sparc.h (PRINT_OPERAND): Recognize 'R' code letter, which

- Accepts an argument saying how to normalize the result and does
- appropriate normalization.

- (compare_from_rtx): New name for compare1.
- Accept size and alignment, for BLKmode.

- (compare): Let compare1 do most of the work.
- (do_store_flag): Rewritten, now lets emit_store_flag do most of

- this will be an expensive operation; all callers changed.
- If it looks like it will be possible to do a store-flag operation,

- to nesting structure (new type stmt_nesting).
- (expand_exit_loop{,_if_false},expand_continue_loop): Accept pointer
- to nesting structure, substitute loop_stack if 0 (same behavior as
- before when there was no argument), so F90 CYCLE and EXIT statements
- (like C's continue and break stmts) can refer to other than the
- innermost loop.
- (expand_start_cond): Uses new names for if-related labels that
- reflect addition of "elseif" call, and sets endif_label to whatever
- exit_label gets set to (so we don't generate two identical labels
- for languages from which if is exitable via expand_exit_something).
- (expand_start_elseif): New function, used by Fortran.
- (expand_start_else): Moved above _end_cond so these four functions
- appear in the order they get called; uses new names, and fills in
- only endif_label if needed, not exit_label.
- (expand_end_cond): Handles end of any if, not just if-without-else.
- Generates both labels for next else/elseif pending (there was none)
- and the endif itself, if they exist (and there will always be at least
- one).
- (expand_end_else): Gone, call expand_end_cond instead.
- * c-parse.y, cplus-parse.y, objc-parse.y: Pass new 0 argument to
- expand_..._loop_... to indicate the innermost loop; call

- (validate_replace_rtx_1): Swap operands on commutative operation
- if first is constant.
- Use plus_constant to simplify a PLUS with CONST_INT as second operand.
-

- a MEM that uses SP.
-
- * combine.c (try_combine): Don't do anything if I2 or I1
- has an ASM_OPERANDS and CLOBBERS; we'll need those clobbers

- Make better use of defaults.
- * m88k.md (peephole), out-m88k.c, tm-m88k.h (short_branch): Add
- the sparc peepholes for changing bsr/br into bsr.n/addu or
- bsr.n/subu. Install the length attribute for this. Requires the
- use of `def' to accomodate broken assemblers in the bsr.n/addu
- case.
-
-Fri Dec 7 06:12:43 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)

-
- * tm-m88k.h, out-m88k.c, m88k.md: More cleanups: introduce
- POWER_OF_2 for tests (x && (x & (x-1) == 0); rename predicate
- functions *_p instead of *_operand; cleanup addsi3 insns; simplify
- udivsi3 insns; simplify memory shift insns; make LOW_SUM and HIGH
- SImode instead of VOIDmode; add a predicate to the increment and

- are based on work done by Steve Chamberlain (steve@cygnus).
- * tm-m88k.h, out-m88k.c (BLOCK_PROFILER, FUNCTION_BLOCK_PROFILER):
- Implemented.
-

- for changed vector.
-
- * out-rs6000.c (output_epilogue): Fix typo restoring general registers.
- (print_operand): Add new option %H.
- * rs6000.md: Add (clobber (reg:SI 64)) to many patterns even though
- they don't clobber MQ to allow combining to work well. This will be
- removed once combine knows how to add clobbers when required.
- Change patterns to reflect new canonicalization rules.
- Where we have (and (xshift)), add patterns for (zero_extend (xshift)).
- (andsi3, xorsi3): Fix bug in case where two insns are needed.
- (moveti): Don't call change_address when in reload.
- (sign_extend): Add patterns for sign extend preceeded or followed by
- one of the shifts it will do. Use %H to output the merged shift.
-
- * out-romp.c (print_operand): Allow exact_log2 result to be zero.
- * romp.md: Likewise.
- * tm-romp.h (CONST_OK_FOR_LETTER): Likewise.

- (movsi, movhi, movqi): No need to support special->special copies.
- Support consthz insn on 29050.
- (compare, scc, and branch insns): Rework to not use cc0. Use a pseudo
- register instead. Compare doesn't generate any code, but merely
- saves the operands. scc and branch then emit the appropriate compare
- and jump (if branch) insns.
- (tstsi): Delete pattern; not used when no cc0.
- (peepholes): Remove peepholes to convert jumps to scc insns; now
- done in jump.c.

- accumulators on the 29050.
- (CONST_OK_FOR_LETTER): Use 'O' for a constant that can be set using
- conthz on the 29050; keep old definition for 29000.
- (STORE_FLAG_VALUE): Now 0x80000000.
- (ASM_FILE_START): Write ".cputype 29050" when compiling for 29050.
-
- * combine.c (subst): Put NOT, NEG, MULT, PLUS, and MINUS as the
- first operand of commutative operations. Note that NOT used to be
- put as the second operand but it has always been assumed that
- MULT would be the first operand in address expressions, so we have
- to change the previous canonicalization. This is possible now that we
- have eliminated the andcbm3 operations.
- * i860.md (andnot): Remove obsolete andcbsi3 name and place NOT
- as first operand.
- * m68k.md (fpm*): Delete patterns with MULT as second operand and
- use "@" construct when possible.

-
- * dwarfout.c (lookup_filename, dwarfout_finalize): changed from
- maintaining a linked list of filename entries to maintaining an
- (expandable) array of filename entries instead. Also, changed
- code so that *all* filename strings are output (to the .files
- section of the asm file) in one swell foop just as the asm file is
- being finalized rather than writing out new filenames one-by-one
- as they arise (as previously). This circumvents a problem caused
- by rfg's naive assumption that assemblers kept a stack of prior
- section names (of depth > 1) which could be successively popped
- via multiple `previous' directives. For some assemblers, the
- depth of the stack is only 1 and they can get confused if you do
- two (or more) `previous' directives in a row. Anyway, it is no
- longer either necessary or useful to do that, so who cares.
-
- * dwarfout.c: added code to output newlines to the asm file just
- prior to each and every change of section (for better readability
- of the asm files).
-
- * dwarfout.c: changed code so that if DWARF_DESCRIBE_USED_EXTERNS
- is defined, it forces DWARF_LOCATION_ATTRIBUTES to also be defined.
-
- * dwarfout.c: changed code so that if DWARF_LOCATION_ATTRIBUTES
- is defined, it forces DWARF_DESCRIBE_FILES to be defined (to `1').
-
- * dwarfout.c: changed code so that if DWARF_DESCRIBE_FILES is not
- already defined (in the user's tm.h file) it will automatically be
- defined (by default) to `1'. Also changed all instances of
- `#ifdef DWARF_DESCRIBE_FILES' to `#if DWARF_DESCRIBE_FILES'.
- The user must now intentionally *disable* this feature (by
- defining DWARF_DESCRIBE_FILES to `0' in his tm.h file) if he
- wishes to have the additional information about files suppressed.
-
- * dwarfout.c: changed comments relating to optional defines for
- extended GNU DWARF features to include more information and to
- add some additional clarity.
-
-Sat Dec 1 16:00:34 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)

- of tracking what AND's need to be done and which bits are not
- significant. Consistently try a ZERO_EXTEND for all cases where
- the result is an AND with a mode-wide mask. Move all remaining
- cases from AND any ZERO_EXTEND cases from subst.

-
-Fri Nov 30 10:39:04 1990 Michael Tiemann (tiemann at cygnus.com)
-
- * cplus-decl.c (finish_function): Use CLASSTYPE_ASM_WRITTEN instead
- of TREE_USED to indicate that we need debugging info for
- TTYPE.
- Note that nobody ever sets EXTENDED_DBX_DEBUG. For now,
- change to test DBX_DEBUG. For later, change everything to
- key off of EXTENDED_DBX_DEBUG.
- Also, set `warn_return_type' to one always, since this warning
- is too valuable to lose.
- * cplus-tree.c (lang_output_debug_info): Don't test TREE_USED. That
- field is already used by other routines, and we have all we need now
- in CLASSTYPE_ASM_WRITTEN.

- * combine.c (gen_lowpart_for_combine): Call gen_lowpart for CONST_INT.
- When making a new MEM, copy MEM_VOLATILE_P and MEM_IN_STRUCT_P.
- If cannot recognize the argument, just form a SUBREG; usually,
- it won't be recognized, but sometimes will allow further
- simplifications.
-
- * regclass.c (reg_scan): Save size of uid map; reallocate if
- we have more registers than we allocated.
- Leave some extra room in map.
-
- * stmt.c (emit_case_nodes): Supply missing argument to emit_cmp_insn.
-
- * fold-const.c (decode_field_reference): Add missing arg declaration.

- THIS_CC0_RTX which is the rtl for the condition code value we are
- concerned about testing. All callers changed.
-
- * flow.c (propagate_block,mark_used_regs): Conditionalize
- specialized cc0 handling only if HAVE_cc0 is defined.
-
- * genemit.c (gen_exp): In REG case, If CC0_REGNUM is defined,
- save space by using REG_CC0_RTX instead of allocating a new
- (REG, mode, CC0_REGNUM) rtx if the mode is SImode.
-
- * final.c (output_addr_const): Handle PC for P.I.C. code generation.
- Also, put parens around CONST expressions so that precedence can be
- maintained.
- * final.c (final_scan_insn): Don't look for redunant compares
- except when HAVE_cc0 is defined.
- Also, use `find_cc' to locate the rtx functioning as the
- condition code register in order to perform appropriate calls
- to `alter_cond'.
-
- * expr.c (expand_expr): Supply missing arg in calls to `store_expr'.
-
- * expmed.c (emit_store_flag): New argument COMPARISON is the
- comparison operation whose result we store.
-
- * recog.c (offsettable_address_p,adj_offsettable_operand): Use
- `plus_constant_for_output' instead of `plus_constant' since we
- are testing conditions which rely on being able to add small
- offsets to e.g. LO_SUM operands.
- * explow.c (plus_constant): No special handling for LO_SUM. It is
- not valid to add a constant to a term with LO_SUM, since the
- constant may need to be added to the high bits that form the sum,
- and those high bits are not readily available.
- * explow.c (plus_constant_for_output): Same as `plus_constant'
- except that we do allow adding constants to LO_SUM terms. This
- function works only in special cases such as for
- `adj_offsettable_operand' and `offsettable_address_p'.
-
- * emit-rtl.c: Declare reg_cc0_rtx which is like cc0_rtx, but
- is a register instead of a special form. reg_cc0_rtx should
- be used when representing the condition code register on a
- machine where condition codes are only set if explicitly set.
- For machines which allow arbitrary registers to be used as
- condition code registers (such as the MIPS and 88k), normal
- pseudo registers should be used instead.
- * emit-rtl.c (next_cc0_user,prev_cc0_setter): Conditionalized
- on HAVE_cc0.
- * emit-rtl.c (find_cc): New function. Given INSN, returns
- the rtx of what functions as the condition code register for
- INSN. On machines which use cc0_rtx, this is always cc0_rtx.
- On machines which have a dedicated register for cc0, this is
- that register. On machines which allocate pseudos for holding
- condition codes, this is the pseudo found in a REG_CC0 note.
- Otherwise, this function returns 0.
- * emit-rtl.c (init_emit_once): Allocate `reg_cc0_rtx' if
- CC0_REGNUM is defined.
-
- * cse.c (make_regs_equiv): Don't consider making a reg
- equivalent to another reg whose class is NO_REGS.
- * cse.c (canon_reg): Don't canonicalize a register to
- one whose class is NO_REGS.
- * cse.c (fold_rtx): Conditionalize code for handling cc0_rtx
- with HAVE_cc0.
- * cse.c (predecide_loop_entry): Generalize code to use either
- a register or cc0_rtx.
- * cse.c (cse_insn): Conditionalize code for handling cc0_rtx
- with HAVE_cc0.
-
- * combine.c (combine_instructions,try_combine,subst):
- Conditionalize code handling cc0_rtx with HAVE_cc0.
- * combine.c (simplify_set_cc0_and): Abort if HAVE_cc0 is not
- defined.
- * combine.c (try_distrib): Add break at end of switch cases. It is
- dangerous to leave the last cases of a switch statement to fall
- through since new cases added after will get fallen into.
-
- * recog.c (validate_change): Always succeed for an asm insn,
- since recog always fails to recognize asm insns. This is
- needed for virtual register instantiation in asm insns.
-
- * cse.c (cse_main): When following jumps, notice whether a
- particular basic block causes CSE_JUMPS_ALTERED to become set. When
- this happens, repeat the scan.
- * cse.c (refers_to_mem_p): Changed parameter name REG to BASE,
- which is more accurate. Also, taught it how to cope with
- LO_SUM rtl constructs.
-
-Wed Oct 24 15:36:12 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * calls.c (store_one_arg): Accept additional arg, FNDECL.
- Don't save argument area if it is within the REG_PARM_STACK_SPACE
- area, but mark the area in use.
- (expand_call): If ACCUMULATE_OUTGOING_ARGS and REG_PARM_STACK_SPACE,
- treat the stack area for the registers as be clobbered by the called
- routine (e.g., if it was compiled without -O) and save and restore
- it if it was previously used for arguments in a similar manner to
- the remainder of the argument area (done by store_one_arg).
-
- * calls.c (expand_call): Support new description macro,
- STACK_PARMS_IN_REG_PARM_AREA.
- * function.c (assign_parms): Likewise.
-

-
- * cccp.c (collect_expansion): Skip ## at start after the error.
-
- * gcc.c (default_compilers): Handle - as suffix.

-
-Tue Oct 23 22:40:33 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * romp.md (store{s,h,q}i pattern): Allow "b" for clobbered pseudo
- in addition to "d" in first alternative.
-
- * reload1.c (eliminate_regs): IF_THEN_ELSE isn't a unary operation.
-
-Tue Oct 23 20:35:13 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * m68k.md (zero-extend QI): When pushing, store value at 1(sp).
-
-Mon Oct 22 12:27:08 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * cccp.c (rescan): In the loop that handles numbers, discard \newline.
- Also make `..' terminate a preprocessing number.
-
- * Makefile.in (tmpgnulib, stamp-gnulib2): Do `set -e'.
-
- * gcc.c (default_compilers): Give __GNUC__ value 2.
- Don't define it for .S files.
-
-Mon Oct 22 07:33:42 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * optabs.c (emit_indirect_jump): New function; now checks predicate
- of indirect_jump.
- * stmt.c (expand_computed_goto, expand_goto): Use new function instead
- of directly emitting indirect jump.
-
- * flow.c (mark_set_1): Make LOG_LINKS for hard registers.
- * combine.c (subst): Make new macro COMBINE_RTX_EQUAL_P which
- considers things equal if they are the identical RTX or the same
- register with the same mode; use to see if something changed and
- if we have a match.
-
- * cccp.c (S_ISREG): Use argument instead of global.
- (main): Correct sense of S_ISREG usage.
- (check_precompiled): Use S_ISREG.
-
- * flow.c (mark_used_regs): Don't allow reg_next_use to point to
- a NOTE; either point it to replacement insn or invalidate it.
-
-Mon Oct 22 00:13:12 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * c-parse.y (xdecls): No warning unless -pedantic.
-
-Sun Oct 21 17:49:24 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * genattrtab.c (cc0_rtx): Define, referenced in rtlanal.c.
-
- * jump.c (jump_optimize): Remove code that depends on changes to

-
- * expmed.c (extract_bit_field): Correctly check for bitfield
- completely filling a mode.
-
- * out-romp.c (output_epilogue): Correctly write number of words of
- arguments into trace table.
-
- * calls.c (store_one_arg): Fix error in change of Oct 19th.
-
- * reorg.c (mark_target_live_regs): Revert back to old behavior
- of scanning all insns, even those in delay slots.
- (fill_simple_delay_slots): Need only call update_block if we move
- an insn across a label.
-
- * Makefile.in (LIBFUNCS): Use consistent naming convention for
- comparison routines; gnulib.c was always correct.
-
- * function.c (assign_parms): Don't overwrite DECL_INCOMING_RTL when
- we are called for the second time.
-
- * integrate.c (initialize_for_inline): Don't make a new return label
- here; the maximum label number has already been computed.
- (save_for_inline_copying, save_for_inline_no_copy): Do it here instead.
-
- * reload.c (find_reloads_address): For indirect address where the
- underlying address is also invalid, ensure that we substitute into
- the MEM that we will use.
-
-Sun Oct 21 14:12:47 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * reload.c (find_equiv_regs): Reject reg that overlaps goal.
-
- * expmed.c (extract_bit_field): For big fields, make sure
- value really goes in the target.
-
- * expr.c (expand_builtin): Delete __builtin_varargs.
- (EXPAND_BUILTIN_SAVEREGS): New macro says how to do __builtin_saveregs.
-
- * calls.c (expand_call): No "can't inline" warning if -fno-inline.
-
- * stddef.h: Add missing #endif.
-
-Sat Oct 20 14:33:14 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * function.c (round_trampoline_addr): New function.
- (trampoline_address): Use that.
-
-Fri Oct 19 15:13:31 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * calls.c (store_one_arg): Don't mark stack area used until after
- we have written into it; if we do it before, the restore might
- clobber a function result being put into that stack area.
-
- * objc-actions.c (print_lang_statistics): Add empty function.
-
- * recog.c (inequality_comparisons_p): Deleted from here.
- * rtlanal.c (inequality_comparisons_p): Moved to here; not static.
-
- * a29k.md (extendhisi2): Fix typo in define_split.
-
- * Makefile.in (integrate.o): Includes integrate.h.
- (reorg.o): Includes insn-flags.h.
-
-Fri Oct 19 14:49:26 1990 Michael Tiemann (tiemann at cygnus.com)
-
- * sdbout.c (sdbout_symbol): If a variable belongs to an inline
- function, the decl's rtl may not be rewritten by alter_reg. So if
- we have a variable allocated to a pseudo, just get the hard register
- number from `reg_renumber'. ?? But I thought that COFF was so
- losing that it was decided one could not represent debug info for
- inline functions in COFF.
-
-Fri Oct 19 13:21:25 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * fold-const.c (split_tree): Use NEGATE_EXPR to negate *conp.
-
-Fri Oct 19 00:15:21 1990 Michael Tiemann (tiemann at cygnus.com)
-
- * version.c: Bumped to 1.90.03.
-
- * tree.c: Added facility for gathering statistics on the number of
- tree nodes allocated and the size in bytes they occupy. The
- statistics are by tree_node_kind, which is almost like using the
- tree code letter, but has more resolution for dealing with different
- kinds of `x' nodes. The facility is enabled by compiling the
- compiler with -DGATHER_STATISTICS and using the -fstats flag.
-
- * expr.c (do_tablejump): Emit a BARRIER after the jump that performs
- the tablejump.
-
- * cplus-typeck.c (c_expand_return): Rewritten so that the function
- value return register is not used except as a target of the function
- return value.
-
- * cplus-tree.c (build_cplus_new): New argument WITH_CLEANUP_P
- controls whether this functino should build its result with a
- cleanup or not. All callers changed.
-
- * cplus-lex.c: File updated to latest changes to c-parse.y's lexical
- analyzer.
-
- * cplus-except.c (cplus_expand_raise): New parameter FOR_RERAISE
- is used to control whether to output extra gotos or not. When
- nonzero, the compiler can avoid writing out the extra gotos that are
- otherwise needed to avoid warning messages.
-
- * cplus-decl2.c (flag_short_double): Add support for this option.
-
- * cplus-decl.c (finish_function): Always cause returns to jump to
- the return label. This allows -Wreturn to give meaningful error
- messages.
-
- * jump.c (invert_exp): Make this non-static.
- (jump_optimize): Reorganization and simplification of main inner
- loop. Comments added explaining what the optimizers are looking
- for. New optimization added that optimizes for consecutive testing
- of an inequality test followed by an equality test (or vice-versa).
- Changes made to accommodate reorg.c on Sparc. Code for
- cross-jumping return statements was previously dead in this
- function; as a result of the reorganization, it is now live.
- (find_cross_jump): Added temporary variable PREV1 to hold return
- value of `prev_nonnote_insn' instead of calling the function 3 times
- in a row. Also changed so that USE or CLOBBERS are not cross-jumped
- unless some real insns are also cross-jumped. This helps reorg.
- (redirect_jump): Fixed a return that returned no value so that it
- returns 1.
- (rtx_renumbered_equal_p): Test that reg_renumber is nonzero before
- using it. We may want to call this function earlier than by the
- time that array has been initialized.
-
- * integrate.c (save_for_inline_{copying,nocopy}): New functions to
- replace `save_for_inline'. save_for_inline_copying saves the rtl
- for inline functions by copying the rtl to the
- maybepermanent_obstack. It is called when the rtl of the current
- function is going to be compiled immediately.
- save_for_inline_nocopy takes advantage of the fact that inline
- function rtl is already allocated to the maybepermanent_obstack, and
- need therefore not be copied if it's not going to be modified by the
- compiler (such as by `rest_of_compilation').
- ({initialize_for,finish}_inline): New helper routines for
- save_for_inline_... functions.
- (note_modified_parmregs): Function called by `mark_stores' to note
- whether parameters are assigned to in the body of an inline
- function.
- New interface, integrate.h, provides declarations for functions used
- by other routines that might want to copy chunks of rtl.
- ({save,try}_constants): Now global (for integrate.h).
- (mark_stores): Ditto.
- (try_fold_condition): Ditto.
-
- * dbxout.c (dbxout_symbol): If a variable belongs to an inline
- function, the decl's rtl may not be rewritten by alter_reg. So if
- we have a variable allocated to a pseudo, just get the hard register
- number from `reg_renumber'.
-
- * varasm.c (output_const_pool): No longer static.
- (assemble_variable): Do output debugging information for global
- register variables. GDB does the right thing for global register
- variables.
-
- * toplev.c: New flag `warn_inline' for warning when a function
- declared inline was not in fact inlined. Also, new flag
- `flag_no_inline' which disables function inlining, but retains
- other properties of inline functions (such as lazy compilation
- and write-only-if-needed).
- * toplev.c (compile_file): Changed logic for inline function
- handling to work with `warn_inline' and `flag_no_inline'.
- Also modified to call `save_for_inline_nocopy' when insns are to be
- saved but not immediately compiled.
-
- * function.c (instantiate_decls): If instantiating a function
- which was saved for inline expansion, preserve the rtl created
- by the instantiation as well.
-
- * flags.h (flag_no_inline): New flag; if nonzero, then no
- calls are inlined, regardless of their declaration. We still
- save the insns for these functions in DECL_SAVED_INSNS so that
- the functions need not be written if they are never called.
-
- * calls.c (expand_call): If `flag_no_inline' is set, don't
- inline the call, regardless of whether it was declared inline
- or not.
-
-Thu Oct 18 13:10:26 1990 Richard Stallman (rms at mole.ai.mit.edu)
-
- * rtl.def (CODE_LABEL): Add new string field.
- * rtl.h (LABEL_NAME): Define macro for access.
- * emit-rtl.c (gen_label_rtx): Initialize it to 0.
- * stmt.c (expand_label): Store proper name of label.
- * final.c (final_scan_insn): Call sdbout_label.
-
- * tree.h (built_in_function): Add BUILT_IN_VARARGS.
- * c-decl.c (init_decl_processing): Declare __builtin_varargs.
- * expr.c (expand_builtin): Generate code for it.
- Uses new macro EXPAND_BUILTIN_VARARGS.
-
- * sdbout.c (SDB_IS_FAKE): Macro deleted.
- (MAKE_LINE_SAFE): New macro.
- (sdbout_begin_block, sdbout_end_block, sdbout_end_function): Use it.
- (sdbout_one_type): Delete spurious second arg in all callers.
- (sdbout_types, sdbout_end_function):
- Use sdbout_dequeue_anonymous_types.
- (sdbout_label): New function.
-
- * expr.h (FUNCTION_ARG_BOUNDARY): Default is now PARM_BOUNDARY.
-
- * gvarargs.h, va-*.h (va_dcl):
- Add ellipsis so current_function_varargs is set.
-
- * jump.c (jump_optimize): Exit push-optimize loop at end of insns.
-
-Thu Oct 18 07:09:06 1990 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * reorg.c: Major reorganization. Many special cases have been moved
- into more general code and an overall restructuring has been done.
- Numerous bugs have been fixed. Highlights:
- (dbr_schedule): First make list of all insns needing filling. Then
- iterate for two passes. In each pass, try two methods of filling
- delay slots, then do some canonicalizations, which may create more
- insns to fill.
- (fill_simple_delay_slots): Now uses list of insns that need filling,
- rather than making such a list.
- Enhance code that finds insns when code paths merge to allow multiple
- uses of the label as long as all uses are in the skipped code.
- (struct resource): Notice volatile memrefs.
- (stop_search_p): Allow option to continue when label is reached.
- (find_end_label, make_return_insns): New functions; when we have a
- filled branch that is really a RETURN, first convert it to a jump
- to a return label and then later see if the insns in the delay slots
- are also valid for a RETURN.
- (mostly_true_jump): Test for branch to loop beginning rather than
- branch at end of loop. Also, conditional return insns predict false.
- (own_thread_p): New function to replace fall_through_to_p.
- (try_merge_delay_insns): Only support merging insns already in an
- insns delay list.
- (get_branch_condition, condition_dominates_p): New functions.
- (steal_delay_list_from_{target,fallthrough}): New functions to
- replace steal_delay_list.
- (redundant_insn_p): New function.
- (update_block, mark_target_live_regs, dbr_schedule): When moving
- an insn not at the front of the basic block to a delay slot,
- leave a "ghost" USE so that we can track things livened and killed.
- (fill_slots_from_thread): Eliminate use of static vars for number
- of slots to fill and already filled.
- Try to modify an insn that follows a register-register copy to use
- the original register; this may create a delay-slot opportunity.
- (try_hoist_target{,_1}): Deleted.
- (relax_delay_slots): Rewritten to just perform canonicalizations
- previously done elsewhere. No actual delay slot filling is done
- here. Any new delay slots created will hopefully be filled in the
- next pass around the loop in dbr_schedule.
-
- * expr.c (emit_push_insn): Don't try to compute a SUBREG of a
- hard register in a non-integer mode when pushing a "partial" arg.
-
- * recog.c (validate_change, apply_change_group): After reload, ensure
- that operands meet the constraints by calling constrain_operands.
- (validate_replace_rtx_1): Consider two rtx equal if they refer to
- the same register.
-
- * jump.c (jump_optimize): Extend change of Oct 16th to handle
- the other usage of find_equiv_reg; remove invalid death notes there.
-
- * rs6000.md, tm-rs6000.h, out-rs6000.c, xm-rs6000.h, make-rs6000:
- New files.
-
- * out-a29k.c (extract_subword): Use gen_{high,low}part from
- an FP CONST_DOUBLE if host and target float formats are the same
- or REAL_IS_NOT_DOUBLE.
-
- * out-romp.c (output_fpop, output_fpops): Provide fr0 as a scratch
- register unless it is used in the insn.
-
- * romp.md: In combined set CC0 and move, optimize case where move
- is nop.
- (DF moves): Fix typo in generation of `get' insn.
- Don't split if input is CONST_DOUBLE because we can't easily
- generate the proper constants.
- (call patterns): Copy data area address via a pseudo to allow
- better CSE'ing.
-
- * tm-romp.h (RTX_COSTS): Memory is expensive, except for a reference
- to our own data area, which is very cheap.
- (ADDRESS_COST): References to the constant pool are as cheap as
- register + offset, since that's what it will be.
-
- * emit-rtl.c (gen_{low,high}part): Can often extract word from FP
- CONST_DOUBLE when host and target floating formats agree.
- (add_insn_after): No longer static.
-
- * reload1.c (reg_equiv_memory_loc): Renamed from reg_equiv_stack_slot
- and now static.
- (reload): If have equivalence with constant that is not a legitimate
- constant operand, force it into memory and handle this as an
- equivalence to memory.
- * reload.h (reg_equiv_stack_loc): Deleted.
-
-Wed Oct 17 20:50:58 1990 Richard Stallman (rms at mole.ai.mit.edu)

-
- * gcc.c (do_spec_1): Null-terminate error message.
-
- * sdbout.c (sdbout_symbol): Handle subreg as DECL_RTL.
- This happens for vars from the parms of inline functions.
- * dbxout.c (dbxout_symbol): Likewise.
-
- * genattr.c (fancy_abort): New function, as in gen*.c.

-
- * final.c (alter_cond): Handle CC_INVERTED.
-
- * conditions.h (CC_INVERTED): New flag indicating that the condition
- tested leaves the falgs set opposite to the condition tested. This
- is unsafe for IEEE floating point operations, but useful for integer
- operations which can combine with condition-code setting operations.
-
- * c-parse.y (position_after_white_space): New function. Skips
- all of the whitespace at the current location in the input
- file, taking NEXTCHAR into account. Changed all callers of
- `skip_white_space' in grammar to use this function instead.
-
- * genrecog.c (main): Generate code which is more easily optimized by
- GCC's cse. In particular, start each recognizer with the address of
- `recog_operands' in a register.

- scheduling before register allocation and
- FLAG_SCHEDULE_INSNS_AFTER_RELOAD for insn scheduling after
- register allocation.
- * recog.c (constrain_operands): Recognize pseudo registers as
- registers for the purpose of insn constraint matching before
- register allocation. Otherwise, the insn scheduler assumes
- the operands will be memory, which is usually wrong (and
- causes it to build bad schedules).
- * sched.c (order_calls): New function. For two CALL_INSNS in
- the rtl chain, we set up a constraint that the second
- CALL_INSN may not be scheduled to run before the first.
- (sched_analyze_*): Three kinds of dependencies (true, anti,
- and output) constrain the order in which insns can be
- rearranged and still preserve their execution semantics.
- We now handle dependencies for pseudo and hard register usage
- and for memory usage in these functions.
- (launch_links): The ordering of which newly ready insns to
- execute is now preserved according to their `priority' in the
- insn chain, and no longer on their order in the dependency
- list from which they were launched.
- (schedule_block): Removed support for trying to schedule insns
- taking branch delays into account. Reorg.c should be hacked
- to understand which insns to pull into delay slots and which
- insns to leave alone.
- (schedule_block): (Re-)compute all register life information here.
- No longer dependent on flow to keep `basic_block_live_at_end'
- allocated.
- (schedule_insns): Recompute LABEL->BASIC BLOCK mapping, so we
- can compute register life information.
- * rtl.c (add_dependence): New function to add and remove insn
- dependencies. If an insn (I2) must execute after another
- (I1), we add an INSN_LIST containing I1 to I2's LOG_LINKS.
- If such an INSN_LIST is already in I2's LOG_LINKS, we don't
- add a second.
- (remove_dependence): Similar, but removes dependencies. May
- not actually be needed.
- * toplev.c (compile_file,rest_of_compilation): Added code for
- dumping info about insn scheduling.
-
-Fri Aug 24 17:24:03 1990 Richard Stallman (rms at mole.ai.mit.edu)

- library routines does not include multiple registers for an arg.

- Remove pair of NEGATE_EXPRs and BIT_NOT_EXPRs.

- ABS_EXPR applied to ABS_EXPR or NEGATE_EXPR is ABS_EXPR of inner arg.
- Convert "a + (-b)" to "a - b" and "a - (-b)" to "a + b".
- If adding ANDs with constants that have no bits, in common, try
- bitwise-or, since we may then be able to distribute the operation,
- e.g., (a & 7) + (a & 0x70) -> a & 0x77.
- Add missing last arg to operand_equal_p call.

- declaration. Dealing with default initializers is basically
- impossible.
-

- until it is in fact an address. This allows us to call
- destructors on the return values of function calls.
-
- * cplus-typeck.c (commontype): Fixed bug in OFFSET_TYPE case which
- led to infinite recursion (since we did not reduce the types
- before we recursed).
-
- * cplus-lex.c (check_newline): Make `#pragma implementation' more

- If predicate doesn't match, ensure that operand is in a pseudo
- register. Current code assumes that any register will suffice,

- reference when FUNCTION_ARG_PASS_BY_REFERENCE is defined.
-
- * varasm.c (assemble_variable): Hack our way around the problem
- that static class members look like initialized variables for the

-
- * cplus-typeck.c (build_component_ref): Make better error message

- path only when PARENT == TYPE_MAIN_VARIANT (PARENT).
-
- * cplus-class.c (modify_vtable_entries): Call get_base_distance

- after change of July 29.
-
- * reorg.c (optimize_skip, try_hoist_target): Don't invert jump
- unless can_reverse_comparison_p says it is OK. Use invert_jump
- to do it.
- (fill_simple_delay_slots): Another way flow of control can merge is
- for two insns to jump to the same place; try to get insns from there.
- (mostly_true_jump): Return 2 for a jump very likely to be true (the
- branch back to the start of a loop).
- (fill_slots_from_thread): Accept new arg LIKELY. If true, see if can
- put increment in delay slot and undo it after the end of the loop.
- (fill_eager_delay_slots): Pass new arg to fill_slots_from_thread.
- If previous insn is conditional jump that also didn't get a delay
- slot, see if swapping targets helps.

- on host machine.
-
- * jump.c: Now includes insn-flags.h.

- control flows through to it.
- JUMP_LABEL can now be zero for a RETURN or conditional RETURN.
- Try to convert jump to end of function into (possibly conditional)
- RETURN.
- Use next_active_insn instead of next_real_insn; these do the same
- thing prior to reload, after which USE and CLOBBERs don't matter.
- redirect_jump may now fail so don't set CHANGED if it does.
- Delete optimization of jump to RETURN; now subsumed by follow_jumps.
- Reset INSN_CODE if changing conditional jump to unconditional.

- * varasm.c (assemble_variable): Delete dead code.
- DATA_ALIGNMENT takes tree and current alignment and gives new

- Adjust DECL_ALIGN to the resulting alignment.
- Use floor_log2 consistently instead of duplicating its function.
- (get_or_assign_label): Use CONSTANT_ALIGNMENT instead of DATA_ALIGNMENT
- and pass type instead of decl.
- * expr.c (get_pointer_alignment): Rework to: distinguish reliably
- between expressions giving the address and those giving the item being
- addressed; use the alignment from the type of the object being
- pointer to; return 0 if the type is not a pointer; and other
- miscellaneous changes.
- (string_constant): Skip CONVERT_EXPR and NON_LVALUE_EXPR as well
- as NOP_EXPR.
- (expand_builtin): Allow get_pointer_alignment to fail, in which case

- since it may be better aligned than required and get_pointer_alignment
- can take advantage of this.
- * tm-gmicro.h, tm-pyr.h, tm.romp-h: Add or replace definitions of
- CONSTANT_ALIGNMENT to word-align string constants and
- DATA_ALIGNMENT to word-align character arrarys for builtin memory

- a delayed-call sequence.
- (final_start_function): Test `only_leaf_regs_used' before
- `leaf_function_p', since that is likely to be faster.
- (final_scan_insns): Normally we don't have NOTICE_UPDATE_CC
- take action when processing the path of an annulled branch,
- since that path does not affect the cc's of the fall-through
- insns at all. However, we cannot always ignore the effect of
- the cc's when processing a delayed annulled branch: when the
- delayed annulled branch follows a label and carries a
- REG_CC_STATUS note, that note must be processed.
-
- * genattr.c (main): Generate #defines for annulled branches
- which are consistent with documentation.
-
- * reorg.c: Finish recent rework by modifying code specific to
- machines that have annulling branches.

- not handle cases of (A == 1) && (B == 1), (A != 0) && (B != 0),
- and (A != 1) || (B != 1). Fixed by expanding the logic out
- longhand and letting the compiler do the proper cross-jumping.

- * expr.c (expand_expr): For BIND_EXPR, do the init for all vars.

- after doing type instantiation.
-
- * cplus-init.c (build_new): New 2.0 interpretation: `new int (10)'
- means allocate an int, and initialize it with 10.
-
- * cplus-init.c (emit_base_init): Completion of fix for virtual
- function table initialization. @@ BTW, this may now cause extra
- virtual function table initializations. They will all be correct,
- but they may also be redundant. GCC's optimizer doesn't know how
- to remove even the simplest such redundancy.

- from beginning of slot, not begining location where arg is stored.
- (store_one_arg): After calling emit_push_insn, argument is really
- at arg->stack_slot instead of arg->stack because if we want to

- introduces new conditional jumps after rearranging loops).
- (rtx_equal_for_thread_p): cheaply builds equivalences between

- faster. Also, test the first letter of each string before calling
- the string comparison function.
-

- former gives better common sub-expression elimination while the
- latter tells the compiler to emit position-independent code.
- (rest_of_compilation): Thread jumps if requested.
-
- * stor-layout.c (layout_{record,union}): For loop bodies meant only
- for FIELD_DECLs, make sure we have a FIELD_DECL before proceeding.
-
- * stmt.c (expand_end_case): Use ADDR_DIFF_VEC if FLAG_PIC is
- nonzero.

-
- * reload1.c (modes_equiv_for_class_p): Only fail if registers in

- in the insn after their birth so they conflict with other outputs.
-
- * vax.md: Replace patterns to convert (and (ashiftxx))
- into (and (rotatexx)) with the patterns that are actually made
- by combine.

- true_regnum.
-
- * out-rs6000.c (output_toc): Write FP constants in TOC.

- insn.
-

- immediately after the jump table
- Remove special-case kludge for ADDR_DIFF_VEC; now handled properly.

- Look for a register used in only one basic block being stored into
- memory.
- Keep track of loop depth so we can find regs used only once, but
- inside a loop.
- * reload1.c (reload): Use single_set when looking for an insn
- that initializes a register.
- If making a REG equivalent to a MEM, the insn with SET_DEST being
- the register isn't always the one making the equivalence, since the
- equivalence might be occurring due to a store into MEM; in that
- case set reg_equiv_init to the latter insn.

- (struct pending_inline): New fields for names and values to bind
- to them while processing.
- (struct template_info): Definition moved here from cplus-pt.c.
- (instantiate_template): Added declaration.
- (instantiate_class_template): Ditto.
- (processing_template_{decl,defn}): New variable declarations.
-
- * print-tree.c (print_node): Provide missing argument to
- print_node for `bitpos' field. Display `virtual' flag, and (for
- function and method types) `class' field; these are only used by
- C++ that I'm aware of, but are defined in common code, so they
- should be displayed here.
-
- * cplus-parse.y (template_def): Separate set of derivations, for
- class and function templates. Template_def is a type of extdef;
- extern_lang_string before template_def is not permitted.
- (fn_tmpl_end): New nonterminal, anything that signals the end of
- the portion of a template that we should parse.
- (yyprint): Define only if YYDEBUG. Handle TYPESPEC.
- (datadef): Complain at class template override declaration if that
- specialization has already been produced by expansion. Template
- definitions no longer belong here.
- (tmpl.2): Always call instantiate_class_template; let it decide
- whether or not to go through with it.
- (template_instantiation): Put decl in global scope only if not
- already there.
- (typespec, scoped_typename): Scoped typename inside template type
- should be a scoped_typename, not a typespec. However, a
- template_type should be allowed as a typespec.
- (structsp): Don't undo template name overload here. Deleted
- derivation from template_type.
- (named_class_head_sans_basetype): Don't overload template name.
- (LC): Do it here.
- (notype_declarator): For scoped_id derivations, don't call
- build_push_scope if the scoped_id is a SCOPE_REF.
- (scoped_id): Moved old typespec-from-template_type rule here.
- Call resolve_scope_to_name only if template parms aren't involved.
-
- * cplus-pt.c (struct template_info): Definition deleted.
- (templates, current_template_info): Variables deleted.
- (processing_template_{decl,defn}): New variables.
- (push_template_decls, pop_template_decls): Accept parmlist and
- arglist as separate arguments, instead of deriving both from the
- template. If class_level is non-zero, push and pop a level,
- making it transparent to tags. Removed some pointless checks from
- pop_template_decls that are only needed in push_template_decls,
- and some assertions from both. Callers changed.
- (uses_template_parms): Return non-zero iff argument refers to any
- TEMPLATE_*_PARM nodes.
- (tsubst): Walk tree, substituting for template parms, returning
- new tree.
- (type_unification): Rewritten a bit, to make it work. New
- argument nsubsts is pointer to place to record number of
- substitutions made when matching.
- (unify): Renamed from unify1. Rewritten completely, to work.
- Still may need extending for some tree node types.
- (do_pending_expansions): At end-of-file, expand any templates not
- yet expanded which were actually needed. Needs work to accomodate
- latest specs.
- (process_template_parm): Simplified slightly. Non-type parms
- should be marked read-only; aggregate types are not allowed, since
- equality checks don't work.
- (end_template_parm_list): Moved to after process_template_parm.
- Push a level, and push decls for TEMPLATE_*_PARMs. Set
- processing_template_decl flag.
- (end_template_decl): For non-class templates, build a
- TEMPLATE_DECL and store the regular decl in its result field.
- Context and other values get copied over too. Call poplevel to
- get rid of the TEMPLATE_*_PARM decls, and call
- dont_forget_overload to avoid losing the declaration later. Clear
- processing_template_decl flag. Call get_pending_sizes, so later
- function compilation doesn't try to evaluate sizes of templates.
- (mangle_class_name_for_template): Convert type/non-type check from
- switch to if test. Added support for ENUMERAL_TYPE, REAL_TYPE,
- and POINTER_TYPE parms.
- (instantiate_class_template): Renamed from old
- instantiate_template. Don't expand if type size is set, or if
- being-defined flag is set, or use-template flag is non-zero. If
- other-template parms are used in the parm list, construct a simple
- RECORD_TYPE node and return it. Catch case of template declared
- but not defined before use. Renamed argument from class to
- classname. Set processing_template_defn flag.
- (instantiate_template): New routine; constructs new decl node
- given TEMPLATE_DECL node and template arg vector.
- (end_template_instantiation): Set use-template field to 2 ("did
- use template"). Clear processing_template_defn flag.
- (reinit_parse_for_template): Get template-info ptr from decl node.
- Store template parm vector in it.
- (pending_template_expansions): List of templates that may need
- expanding later for function or class data definitions.
-
- * cplus-method.c (build_overload_value): Ensure tree code is
- PARM_DECL. Handle ENUMERAL_TYPE like INTEGER_TYPE. For DImode
- values, compare against integer_zero_node instead of constructing
- another one. Added support for POINTER_TYPEs. If not
- REAL_IS_NOT_DOUBLE, support real values as well.
- (build_overload_name): Accept TEMPLATE_*_PARM nodes, but generate
- a string that should cause some assembler errors.
-
- * cplus-ptree.c (print_lang_decl): Retrieve template-info from its
- new place.
- (print_lang_type): For TEMPLATE_TYPE_PARM, print its (short) info
- and return. For RECORD_TYPE, print use-template and interface-*
- fields.
-
- * cplus-search.c (push_class_decls): Don't call
- push_template_decls; the bindings of template parameter names
- should be associated with the template body, not with the class.
- Do overload the template name, however.
- (pop_class_decls): Don't call pop_template_decls.
-
- * cplus-call.c (build_method_call): Changed to recognize
- constructor of template class.
- (build_overload_call): Add in number of template substitutions as
- extra cost of a candidate function. For template decls, try
- unification and instantiation before evaluating cost of result.
- This too is incorrect in terms of the spec, but it's a starting
- point for later work.
-
- * cplus-class.c (finish_struct): If structure is named, undo
- overload of its name as a template.
- (pushclass): If prev_class_type was a template class, pop it; the
- decls are handled wrong and should be re-entered.
-
- * cplus-decl.c (poplevel): Assert that the current level is not
- global.
- (push_to_top_level): Include global scope when looking for old
- values, because class bindings aren't listed in any other one
- place.
- (push_overloaded_decl_top_level): New function; like
- push_overloaded_decl, but places decl in global binding level.
- (dont_forget_overload): New function; removes decl from list of
- overloads to be forgotten when scope is exited.
- (start_decl): If template parms are used, construct a
- TEMPLATE_DECL node referencing the current decl. For function
- templates, call push_overloaded_decl; for class template members,
- chain them into the class template definition.
- (grokdeclarator): Don't try determining size of a
- TEMPLATE_CONST_PARM node. For template class-data decls,
- construct a phony VAR_DECL node and return it.
-
- * cplus-decl2.c (grokfield): For static class data, use
- build_overload_name result, instead of copying class name, since
- the latter could be a human-readable template class name. (If
- NEW_OVERLOAD_SCHEME is not defined, do this only if the class has
- a template-derived name.)
-
- * cplus-lex.c (pending_template_obstack): New variable; obstack
- for pending-template stuff to be saved to end-of-file.
- (init_lex): Initialize it.
- (default_def): New variable; used for default definition of copy
- constructors and destructors.
- (do_pending_inlines): Figure out whether text is in an obstack,
- and which one, for calling feed_input. Push template decls if
- needed, as specified in pending_inline data. Pass current
- pending_inlines pointer back in PRE_PARSED_FUNCTION_DECL instead
- of next.
- (process_next_inline): Ditto. Pop pending inline data if needed.
- (store_pending_inline): New function. Decides which obstack to
- store a pending definition on, and which list to chain it into.
- (reinit_parse_for_method): Call it.
- (reinit_parse_for_block): If character passed in is '=', look for
- a semicolon to end the block; don't require a {} block. Don't pad
- to 8 bytes on USG, since we aren't feeding input via stdio any
- more. Also, use newlines instead of # directives for advancing
- line number only a few lines.
- (cons_up_default_function): Punt padding for USG stdio, since we
- aren't using it any more. Use default_def for definition. Call
- store_pending_inline to save it away.
- (identifier_type): For TEMPLATE_DECL, DECL_RESULT field non-null
- indicates a non-type template, so don't return PTYPENAME.
- (yylex): If end-of-file and input isn't redirected, call
- do_pending_expansions and maybe start yylex over. Don't check
- TEMPLATE_EXPANSION_NAME_P; a proper name transformation system
- will eliminate conflicts. Try for SCOPED_TYPENAME with PTYPENAME
- too.

- vtables in initialized data space.
-

- (mark_used_regs, case MEM): Clear last_mem_set.
- Call find_auto_inc; move code to there.
- (mark_used_regs, case SET): Don't call recursively on MEM if it is

- (compute_frame_size, save_restore, function_prologue,
- function_epilogue): Change the calling sequence of

- to be called.
- (function_prologue): INIT_CUMULATIVE_ARGS now takes 3 args.
- (function_epilogue): If current_function_epilogue_delay_list is

- pinpoint exactly which pattern is used.
- (*divsi3, *divmodsi4, *modsi3): If optimizing and not -mdebugc, use
- the *divmodsi4 patterns, so that the opimizer will only use 1 divide
- if doing a = b / c; d = b % c; This replaces the peepholes, which
- previously were used for this. If not optimizing, use the normal
- div/mod patterns.
- (zero_extendqihi2, extendqihi2): Allow zero/sign extending from

-
- * mips-tfile.c (whole file): New file to put the MIPS specific debug
- information into the object file, after the assembler has been run.
- This is needed because the MIPS assembler provides no method of
- setting up the debug information for local variables. This is
- enabled by the make-mips Makefile modifier.
-
- * mips-tdump.c (whole file): New file to dump the contents of the
- MIPS ECOFF symbol table in a symbolic format. This is not currently
- built by default, but make-mips contains rules to build it.

- (refers_to_mem_p): Handle the case when `base' is a LO_SUM.
- * integrate.c (FIXED_BASE_PLUS_P): Define this to recognize offsets
- from the various virtual registers.
- (expand_inline_function): Expand exprs using EXPAND_SUM so as to get
- stack frame addresses instead of pseudos. This yields much better
- cse (at little cost) for GNU C++. Also, test FIXED_BASE_PLUS_P as
- an alternative to CONSTANT_P to record a known register value.
- * jump.c (find_cross_jump): If we are processing a cross jump and
- the insns fail to match, try looking for a REG_EQUAL note that makes
- them equivalent insns. If found, keep going. This is important for
- merging cleanup codes when one cleanup path gets frame address in a
- register when the other path gets the frame address explicitly.

- argument in call to `build_delete' if DECL does not use virtual
- baseclasses. If it does, we go through a function call to save
- space, unless FLAG_EXPENSIVEO_OPTIMIZATIONS is nonzero. ??Better
- approach is to know, in expand_cleanups, to clear `flag_no_inline'
- during the cleanup's expansion.
-

- where we know we are calling a destructor for a non-null object.
-

- from the block being exited, in addition to any inner blocks
- for which LABEL is now defined.
- (expand_return): Take care of destructors that occur in the
- current binding level.
- (fixup_cleanups): If we emitted no insns, don't change *BEFORE_JUMP.

- Remove loop with n from factor synthesis. Remove -2 bias from m
- loop (for clearity). Add code to use load-effective-address
- instructions. Use bit-fiddling instead of loop to determine q in

- plow through.

- factor of 2. This becomes noticable with the long names used for

-
- * cccp.c (hack_vms_include_specification): Modified conversion of
- unix filenames to VMS filenames, if no VMS device or directory is
- present, and a unix style directory name is present, then use the
- first unix directory name as the VMS device spec. This is only
- used in '#include <...>' type includes, when the include file has
- not been found in the standard locations.
-
-Thu May 2 10:06:47 1991 Micheal Tiemann (tiemann at pogo.gnu.ai.mit.edu)
-

- -fgc is requested.
- * cplus-init.c (build_new): Argument to build_compound_expr must be
- a TREE_LIST all the way. The last elt of the chain cannot be an

- * c-decl.c (finish_enum): Clean up re-laying out of type.
-
-Wed May 1 08:04:44 1991 Michael Tiemann (tiemann at cygnus.com)
-
- * Makefile.in: Handle new cplus-*.c files.
-
- * cplus-typeck.c (common_base_type): Make this function recursive.
- (build_component_ref): Test whether or not a FIELD_DECL, not whether
- or not a VAR_DECL||CONST_DECL||TYPE_DECL.
-
- * cplus-parse.y: Fixed grammar so that template type decls could be
- used. Previously, support existed for template decls following
- types, but not as types.
- * cplus-pt.c ({push,pop}_template_decls): New functions.
- (instantiate_template): Call `push_template_decls'.
- (end_template_instantiation): Let `poplevel' restore old bindings.
- No need to clear out extra stuff.
- (pushclass, popclass): Call `{push,pop}_template_decls' if the class
- we are pushing or popping has template arguments. These arguments
- go at class level.
-
- * cplus-method.c (build_opfncall): Test TRY_SECOND before testing
- possibly uninitialized XARG2.
-
- * cplus-lex.c (init_lex): Initialize NODE_TABLE, OPNAME_TAB and
- ASSIGNOP_TAB to hold zero. Since these come from malloc'd memory,
- we cannot trust them to be initialized on startup.
-
- * cplus-init.c (expand_aggr_init_1): When initializing through a
- TARGET_EXPR for objects of the same type (e.g., X a = X (10);)
- use EXP's DECL_RTL as the DECL_RTL of the TARGET_EXPR.
-
- * cplus-decl2.c (finish_file): Handle new flag `-fgnu-binutils'.
- When zero, don't use GNU extensions to a.out format. ???Should be
- merged into varasm.c.
-
- * cplus-class.c: Added support for `dossiers'. This support is
- implemented by extending the virtual function table and by giving
- all C++ objects a virtual function table to hold it's dossier.
- * cplus-decl.c (record_builtin_type): New function to construct
- dossier information for built-in types.

- (init_lex): Recognize new reserved words `headof' and `classof' if
- -fgc.
- * cplus-parse.y: Grammar now recognizes `headof' and `classof'
- expressions.
- * cplus-method.c: Added dossier constructors here.

- that come from nested types. For example, int foo::bar (foo_tag);
- where `foo_tag' is a tag that comes from foo. Previously this was
- supported only as int foo::bar (foo::foo_tag);
- * cplus-decl2.c (build_push_scope): build a SCOPE_REF node while
- pushing into the context for the scope. When `grokdeclarator' sees
- one of these nodes (distinuished by its TREE_COMPLEXITY being set to
- the current_class_depth), it processes the decl and pops the scope.
-
- * cplus-class.c (build_vbase_path): Trust objects that are
- `fixed_type_p'. Also, don't assume an object is non-null unless
- flag says this is explicitly so. InterViews creates and may
- manipulate (via delete) lots of null objects.
- (build_vfn_reference): Use IS_AGGR_TYPE test on type, not in
- INSTANCE.
- (resolves_to_fixed_type_p): New argument NONNULL is used in case we
- know and object to be non-zero. All callers changed.
-
- * cplus-call.c: New file, from file cplus-class.c. Contains code to
- generate method calls.
- * cplus-class.h: New file, contains common declarations for
- cplus-class.c and cplus-call.c.
-
- * cplus-class.c (finish_struct_bits): Don't leave last_conversions
- uninitialized.

- choosing the section. Use the data section for variables and
- constants that are otherwise read-only when -fpic is given and
- when link-time relocations are required.
- * tm-*.h (SELECT_SECTION): Accept a new second parameter RELOC.
-
-Tue Apr 30 10:24:36 1991 Tom Wood (wood at dg-rtp.dg.com)

- note indicating the virtual top of a loop.
- * jump.c (duplicate_loop_exit_test): Mark the duplicated exit code
- in the loop as the virtual top of the converted loop.
- (squeeze_notes): Move loop-vtop notes as well.
- * loop.c (scan_loop): When a loop-vtop note is encountered, reset
- `maybe_never' and `call_passed'.
- (strength_reduce): Similarly, reset `not_every_iteration'.
-
-Tue Apr 30 08:15:50 1991 Michael Meissner (meissner at osf.org)
-
- * expr.c (do_store_flag): Move the join label after setting the
- target value to 0, rather than before, which generates code that
- always stores 0 into the target if the machine does not have a
- builtin scc operation.
-
-Tue Apr 30 06:26:36 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * reload1.c (reload): When making reg_equiv_mem and reg_equiv_address
- from reg_equiv_memory_loc, clear the one we aren't setting; it might
- have been previously set.
-
- * final.c (final_scan_insn): Correctly handle when the first insn in a
- SEQUENCE is a JUMP_INSN that forces restoration of a comparison
- previously thought unnecessary.
-
- * fold-const.c (fold, case PLUS_EXPR): If we have 2 * real_cst,
- fold into a new constant instead of making real_cst + real_cst.
-
-Mon Apr 29 23:09:17 1991 Ken Raeburn (raeburn at watch.com)

- cplus-lex.c (yylex): Turn it into END_OF_SAVED_INPUT.
- (process_next_inline): Require it after inline function body.

- (yyungetc): Turn conditional abort into assertion test.
- (note_list_got_semicolon): Since variable "type" is available, use
- it rather than recompute.
- (identifier_type): Now static.

-
- * cplus-parse.y (temporary_scope): New variable.
- (object and scoped_id actions): Set it to current type.

- (scoped_typename): Now derivable also from scoped_id and TYPENAME.
- cplus-lex.c (yylex): If temporary_scope is set, use it to
- determine type of current token being examined, instead of looking
- always in the global scope. (Can't properly do nested template
- classes otherwise.)
-
- * cplus-ptree.c (print_lang_decl): Print out template-info,
- original-name, decl-main-variant, and pending-inline-info nodes if
- not null.
-
- * cplus-pt.c (mangle_class_name_for_template): For negative

- they have no values.
- (yyprint, YYPRINT): New function and macro to work with debugging
- code added to bison.

- than calling yyungetc and yylex. Require trailing semicolon.
- (fn.def1 -> PRE_PARSED_FUNCTION_DECL action): Preserve all of
- terminal value, instead of just TREE_PURPOSE.
- (tmpl.1 action): Do instantiation only if '{' or ':' not found.
- (template_instantiation): Call overload_template_name right away.

-
- * loop.c (scan_loop): When see a REG_EQUAL note, check for both
- the move_insn and the REG_RETVAL case, since they can occur together.
- (move_movables): For the move_insn case, handle library calls just
- like the older normal case code below, that is, skip to the end of a
- library call when when see a REG_LIBCALL note, and delete an entire
- library call if when see a REG_RETVAL note.
-
-Mon Apr 29 12:58:19 1991 Jim Wilson (wilson at cygnus.com)
-
- * sched.c: (schedule_block): Rewrite code that computes which
- registers are live at the end of the block. Compute this from

-
- * m88k.md (various patterns): Use nonimmediate_operand in place of
- reg_or_nonsymb_mem_operand and constraint `m' in place of `Q'.
- * tm-m88k.h (EXTRA_CONSTRAINT): Only needed for a call address.
- * out-m88k.c: reg_or_nonsymb_mem_operand and symbolic_memory_p are
- now unused.
-
- * m88k.md (symbolic store patterns): These patterns are all
- unnecessary and are deleted.
- * out-m88k.c (emit_move_sequence): Eliminate the case that
- generated a CLOBBER. This was intended to use the symbolic store
- patterns, but isn't needed.
- (symbolic_memory_operand): Delete, no longer used.
- (output_prologue): Don't check for suspicious register elimination
- changes.
- * tm-m88k.h (GO_IF_LEGITIMATE_ADDRESS): Treat the frame pointer

-
- * out-sparc.c (output_scc_insn): Clean up and expand comments.

-
- * cplus-class.c (prepare_fresh_vtable): Thoroughly update virtual
- function tables that come from baseclasses to contain the latest
- overrides from derived classes. This was done (in a different way)
- for virtual baseclasses, but left undone for non-virtual
- baseclasses.
- (finish_struct_bits): Use assoc lists instead of class basetype list
- to walk through the classes base classes. This gives us more
- relavant classes to check against.
- * cplus-init.c (init_vfields): New function to recursively walk
- objects and make sure their vfields are initialized.
- * cplus-init.c (emit_base_init): Call `init_vfields' from top level.

- inline', don't give it global visibility, regardless of what #pragma
- interface/implementation suggests.
-
- * cplus-decl.c (finish_function): ??? Questionable change for PIC:

- inline, since this somehow reduces page sharing. Really???
-
- * cplus-except.c (init_exception_processing): Use `pushdecl' to
- install global info that this function sets up. That way later
- decls can override this info (such as with an inline function).
-
- * cplus-init.c (build_vec_delete): Set TREE_SIDE_EFFECTS of
- controller. Otherwise the loop won't execute.
-

- we would also output enclosing type.
-
- * cplus-typekc.c (c_expand_return): Use pseudo for intermediate
- return value if necessary. GCC can't read the function return
- registers in an inline functino when the return value is being
- ignored.
-
-Mon Apr 22 14:36:01 1991 Jim Wilson (wilson at cygnus.com)
-
- * sched.c (init_alias_analysis): Handle REG_EQUIV notes just like
- REG_EQUAL notes.
-
- * sched.c (sched_analyze_2): Don't recurse on constant rtx's.
- This is necessary so that the cc0_rtx in CONST_DOUBLEs won't be seen.
- (sched_analyze): Call sched_analyze_insn for JUMP_INSNS also, so
- that cc0 users will get an automatic dependence on their previous
- insn.
- (launch_links): Ifdef out special treatment of insns which set the
- condition codes. This is obsolete, and was SPARC specific anyways.
- (new_sometimes_live): Clarify code that aborts if regno is greater
- than max_regno.
- (schedule_block): If the last insn sets cc0, then it must always
- be left in place.
- (new_insn_dead_notes): New function. Determines whether a SET or
- CLOBBER in an insn created by splitting needs a REG_DEAD or
- REG_UNUSED note added.
- (update_links): Ignore REG_EQUIV and REG_EQUAL notes on insns that
- have more than one set. Generalize flow analysis of the sets in
- the new insns so that it can handle new insns which have multiple
- sets or new clobbers.
-
-Mon Apr 22 08:15:50 1991 Michael Meissner (meissner at osf.org)
-
- * gcc.c (input_suffix): New global var; holds current file's suffix.

- Check for setting biv with single_set rather than only allowing a SET.
- If a loop has a `break', we can't reverse it.
-
- * cse.c (cse_insn): Fold inside operands of a CALL (mostly to find the
- best address form to use).
-
- * cse.c (simplify_unary_operation): Convert (neg (neg ..)) to NEG.
- Similarly for NOT.
- (simplify_binary_operation): Simplify things like (-a) + b.
- Convert UDIV with divisor a constant power of two into LSHIFTRT.

- Only fold shifts of a zero by a value into zero if the value has
- no side effects.
- Remove code to handle negative shift counts.
-
- * tm-a29k.h (OPTIMIZATION_OPTIONS): Allow insn scheduling to be
- enabled, now that it works for the 29k.
-

- to out_operand to avoid conflict with output_operand in final.c.
- * a29k.md: Likewise.

-
- * unroll.c (final_giv_value): Use expand_binop instead of
- gen_sub2_insn when emitting subtract insns, since expand_binop
- will work for any operands.
-
- * sched.c (schedule_insns): Don't split no-op moves; doing so
- breaks the code that handles REG_NO_CONFLICT blocks.
- (update_links): Delete the code that prints a warning for
- REG_EQUAL notes where the original dest can't be found. This no
- longer occurs because of the above change.
-
- * sched.c: Generalize memory aliasing code so that it will work on
- non-RISC machines. Instead of saving just the insn on the pending
- lists, now saves both the insn and the mem rtx. Old variables
- pending_read and pending_write replaced with pending_read_insns,
- pending_read_mems, pending_write_insns, and pending_write_mems.
- (read_dependence, true_dependence, anti_dependence,
- output_dependence): Now passed a MEM rtx instead of a PATtern.

-
- * gnulib1.c (various functions): Added declaration of INTIFY to

-
- * reload.c (find_reloads): Like prev change here, for optional reloads.

- New macros. Place reference to constructor or destructor into
- constructor or destructor section.

-
- * jump.c (squeeze_block_notes,squeeze_notes): Chage the name of

-
- * sched.c: Update all comments to reflect source changes.
- Make old_live_regs a static global, instead of local to schedule_block.
- Schedule_block is now void, since its return value was always 1.
- Rename last_function_call_not_const to last_pending_memory flush.
- This can not be a CALL_INSN or a INSN that writes memory.
- New variable pending_lists_length so that the lists can be flushed
- when they get too long.
- Use GET_RTX_CLASS instead of multiple GET_CODE calls whenever it
- makes sense.
- (read_dependence): New Function. Returns one if two reads are
- dependent. This can happen if both are volatile reads.
- (true_dependence, anti_dependence, output_dependence): Two volatile
- memory access are always dependent.
- (order_calls): Function deleted. It was very short, it was only called
- once, and it no longer did what its name implied. Its one call was
- replaced with the body of the function.
- (sched_analyze_1): Correctly handle stripping of SUBREGs, etc from
- the set dest.
- If the pending lists are longer than 32 when processing a memory
- write, then make this write depend on all previous and all future
- memory accesses so we can flush the pending list. This is necessary
- because the algorithms used are O(N*N).
- (sched_analyze_2): For memory reads, check whether it is read
- dependent on any previous memory read (this can happen if both reads
- are volatile).
- (sched_analyze_insn): Replace call to order_calls with the body of
- that function.
- (sched_analyze): Don't clear last_memory_pending_flush for a non-const
- call, since any future call must still depend on all previous memory
- accesses.
- (sched_note_set): Correct handling of SUBREGs, etc. For partial sets
- of a register, must treat this exactly the same way as flow.c, i.e.
- a partial set of a register does not kill the register. Delete
- ifdefed out code which is obsolete.
- (attach_deaths): New argument SET_P, which indicates whether this is
- a set (if true) or a use (if false) of the rtx X. Correct handling
- of REG_DEAD notes, to account for the new REG_UNUSED note.
- (attach_deaths_insn): Pass new additional parameter to attach_deaths.
- Always call attach_deaths for sets within a parallel. Call
- attach_deaths for clobbers.
- (new_sometimes_live): Ifdef out code which should never be executed,
- and replaced with call to abort.
- (schedule_block): Now void.
- When processing block to find dead_regs, don't unlink REG_UNUSED notes,
- but must mark the indicated register as dead.
- (update_links): Completely rewritten to make more general. Now handles
- all REG_NOTEs except REG_INC and REG_LABEL. No longer makes simple
- assumptions about the form of instructions. New argument orig_insn,
- which is the original unsplit insn.
- (schedule_insns): Delete unused volatilep code. Pass new parameter
- to update_links.

-Wed Apr 10 21:53:32 1991 Jim Wilson (wilson at cygnus.com)
-
- * unroll.c: Change global variable declarations to static.
- Four new global variables loop_iteration_var, loop_initial_value,
- loop_increment, and loop_final_value, used for communication between
- loop_iterations and precondition_loop_p.
- (unroll_loop): Before deleteing the insns in the original loop body,
- emit a label after the last insn to be deleted, to ensure that no
- delete_insn call will delete past that point.
- (precondition_loop_p): Use global loop_* variables setup by
- loop_iterations, instead of trying to calculate their values again.
- (copy_loop_body): Don't emit copies of the start_label.
- (approx_final_value): COMPARISON argument now passed as the pair
- COMPARISON_CODE and COMPARISON_VALUE.
- (find_splittable_regs): When completely unrolling a loop, and the
- initial value of a biv is a hard register or itself, then must
- create a new register to hold its initial value for splitting.
- (loop_iterations): Set the new global variables loop_*.
- If the comparison value is an invariant register, then search the insns
- before the loop to try to find a constant value for the register.

- fixed and r1 need not be saved for PIC.
- (output_prologue): Output instructions to setup the addressing
- base register if one is needed.
- (print_operand_address): Support the PIC case.

- use the bison -l option to allow debugging in c-parse.tab.c.
-
- * From kenner@vlsi1.ultra.nyu.edu.

- function's original DECL_INITIAL tree.
-
- * loop.h (new file): Move many declarations from loop.c to the new

- loop_number_loop_starts and loop_number_loop_ends so that they won't
- be confused with local loop_start and loop_end variables.
- New variables loop_number_exit_labels, loop_number_first_block,

- Remove static from definition, so that it can be called from unroll.c.
- (strength_reduce): Change name of variable maybe_never to
- not_every_iteration, to help emphasize that it is not the same

- in better code.
- (strength_reduce): Added code to call the new loop unrolling
- functions, e.g. unroll_loop, loop_iterations, etc.
- (strength_reduce): New code to handle biv's and giv's which must
- be set to their final_value after the loop exits.
- (strength_reduce): Reversed giv's and biv's must have their values

- replaceable, try to calculate their final value, and then try
- to use this to make them replaceable.
- (update_giv_derive): Skip inner loop if giv is known to be underivable
- at the beginning. Must set cant_derive if we pass an insn that
- modifies the giv's biv, and we can't calculate an adjustment.
- (emit_iv_add_mult): Remove static definition so that it is callable
- from unroll.c.
- (check_dbra_loop): Reversed biv's must be marked as such, so that
- they can be treated specially in the rest of loop.c.
- (final_biv_value): Moved to unroll.c, alongside the new function
- final_giv_value. Extensively rewritten to work for most common
- cases.

- (reinit_parse_for_method): ...and here.
-

-
- * cplus-tree.c (__eprintf): Added this function from gnulib2 until
- gnulib configuration is worked out.

- was wrong (using a goto to factor common code) because the parse
- stack was different in the two contexts.
- * cplus-init.c (do_member_init): New function.
-
- * cplus-typeck.c (build_compound_expr): Convert arrays to pointers.
- (build_c_cast): Warn about possible alignment problems.

-
- * reload.c (find_reloads): Disallow a PLUS as an operand even if

-
- * combine.c (distribute_notes): If we are searching back for the last
- use of a register I3 and I2 no longer use and the last use is a SET

- a REG_UNUSED note.
-
- * combine.c (try_combine): If I3SRC is a register and I2 is a
- multi-output insn, see if we can replace one of the outputs with

- up a bit.
- (invert_jump): Allow invert_exp and redirect_jump to fail.
- (invert_exp): Only invert jump, don't change target.
- If can reverse comparison code, try it using validate_change.
- If that doesn't work, swap the arms of the IF_THEN_ELSE. If that
- doesn't work, return 0.
- (redirect_exp): Now static.
- * expr.c (do_jump_for_compare): Call invert_jump to invert jump
- to false label after emitting jump; if this fails, convert to
- jump around unconditional jump to false label.
- (do_store_flag): Set to 1 first, then branch, then set to 0. This
- avoids inverting branches.

- (mark_used_regs): Don't set reg_first_use.
- * global-alloc.c (global-conflicts): Dead outputs are now denoted by
- REG_UNUSED notes, not REG_DEAD.
- * reload.c (find_dummy_reload): Delete test of REG_UNSET; add test
- of REG_UNUSED.
- (find_equiv_reg): Don't re-use an output marked as REG_UNUSED;
- we want these notes to be accurate; this would rarely win anyway.
- * reload1.c (emit_reload_insns): Test REG_UNUSED to see if an
- output won't be used any more.

- (qty_clobber): No longer needed.
- (reg_qty): -1 if register cannot be allocated by local-alloc.

- Don't initialize qty_... vars that are always set before use.
- (block_alloc): Delete insn_map, max_uid, and call_used.
- Insn numbers start at 1 and we have two entries in regs_live_at
- for each insn.
- Search for REG_NO_CONFLICT block when we see a CLOBBER insn; this
- avoids having already seen sets to the output register.
- Call wipe_dead_reg for anything in a REG_UNUSED note.
- Delete references to reg_first_use.

- Never tie pseudos if SREG already has a quantity assigned.
- When updating size, use reg_next_in_qty instead of looping over
- all registers.
- (reg_is_set): Just call reg_is_born. Where it is born depends on
- whether we have a CLOBBER or not. Birth location is now twice
- the insn number.

- can't find death note or if R1 is a hard register.
-
- * m68k.md (divsi3, udivsi3): Remove patterns. Using divmodsi4 and
- udivmodsi4 produces better code.
- (divmodsi4, udivmodsi4): If remainder isn't needed, use divsl/divul
- instead of divsll/divull.
-
- * integrate.c (expand_inline_function): Remove change of March 20th.
- Instead, expand args in two passes. First, expand all that go
- into registers. Then do those in memory with store_expr.
-
- * integrate.c (initialize_for_inline): Put the original copy of the
- address into ARG_VECTOR; the new one will be modified.
-

- as well as an input.
-
- * flow.c (mark_label_ref): Don't blow up when X is 0.

-
- * alliant.md: Eliminate unneeded patterns: HImode zero_extract,
- (set (cc0 (subreg ...))), (set (cc0) (and ...)),
- (and (zero_extend ...) ...), shift right of 24 and 16.
- Use alternatives to select assembler template when possible.
- Use const_int_operand instead of immediate_operand when
- possible to avoid explicit test for CONST_INT.
- Write add-and-branch patterns with PLUS removed, the way combine
- produces them.
-
- * rtlanal.c (refers_to_regno_p): If X is a SUBREG of a hard
- register, treat it as if it were the appropriate register.
- CLOBBER doesn't refer to anything.
-
- * final.c (final_scan_insn): Use prev_nonnote_insn, not PREV_INSN,

- Dec 26th from doing anything.
-
- * toplev.c (do_abort): New function, just calls abort.
- (main): Set lang_expand_expr to address of do_abort; abort might be
- a macro that is more than just a function name.
-
- * cse.c: (qty_... variables): Refined to be undefined for indices
- less than MAX_REG. Thus, we need not intialize them at the start
- of a basic block and can instead inialize a quantity as we create it.
- (reg_{next,prev}_eqv): These variables will now be defined only when
- reg_qty[N] != N and hence need not be initialized every block either.
- (new_basic_block): Need not initialize reg_rtx for new block; the
- only time we can inherit values from previous blocks is for hard
- regs and it doesn't matter in that case.
-
- * c-parse.y (yylex): Avoid use of size_t; it may not be defined.
- Cast alloca to (char *).
-
- * out-romp.c (update_cc): cc_status.value[12] can also be a COMPARE,
- so use reg_overlap_mentioned_p to see if an insn that modifies a
- register invalidates cc0.
-
- * reorg.c (link_cc0_insns): If next insn is a SEQUENCE, the insn
- using cc0 is the first insn in the sequence.
- (mark_target_live_regs): Don't assume that a REG_DEAD note always
- refers to a register.
-
-Sat Mar 23 15:35:59 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
-
- * reload1.c (reload_reg_free_before_p):
- An input reload is use before an output or output address reload.
-
- * genoutput.c (validate_insn_alternatives): New function.
- Loop over insn's alternatives to find out how many
- alternatives the insn pattern is to support. Verify that if
- any alternatives are specified for a given operand that the
- number of alternatives match the numer of alternatives for
- this insn.
- (gen_{insn,peephole,expand,split}): Call
- `validate_insn_alternatives' after scanning the insn. This
- sets up the value N_ALTERNATIVES for the insn so that
- `process_template' can check that the number of alternitves
- given matches the number of asm choices for `@' constructs.
-
-Sat Mar 23 08:09:57 1991 Michael Meissner (meissner at osf.org)
-
- * dbxout.c (toplevel, dbxout_init): Instead of always using `Ltext'
- as the label at the beginning of the text region, properly localize
- it, so that machines which do not put leading underscores in front
- of external names do not have a problem if the user uses `Ltext'.
- (dbxout_init): Call text_section before putting out localized
- `Ltext', in case ASM_FILE_START put us into a different section.

-
- * a29k.md (jumpfdec): Simplify pattern to match what combine will
- produce; remove reversed pattern.

-
- * out-romp.c (update_cc, case CC_COMPARE): Call CC_STATUS_INIT.
- * romp.md: In pattern that sets cc0 and copies a register to another
- register, allow the output to be in memory so that we don't get an
- output reload, which will cause problems.
-
- * varasm.c (assemble_variable): Ensure DECL_INITIAL is non-zero
- before we reference it; it might be zero if -fno-common.
-
-Fri Mar 22 16:11:35 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)
-
- * toplev.c (abort): Don't declare if defined as macro.

- * rtlanal.c (dead_or_set_p): A register is dead if it is assigned
- via a SUBREG that references the all the words in the register.
-
- * tm-vax.h (CONST_OK_FOR_LETTER_P): Define `I' to be constant zero.
- (CONST_DOUBLE_OK_FOR_LETTER_P): Define `G' to be floating zero.
- (CONST_COSTS): +/- 1 should be very cheap due to decl/inc/aob/sob.
- (PRINT_OPERAND): Add `P', `N', `H', and `B'.
- * vax.md: Rework many patterns to avoid C code for output template;
- use "@" construct whenever possible.
- Use INSN_DELETED_P.
- Remove extendsidi2; the supplied pattern does exactly what convert_move
- will do when the pattern is not present.
- Use constm1_rtx to check for constant of -1.
- Add mulsidi3 and related add-multiply pattern for emul insn.
- Use const_int_operand as predicate instead of checking for CONST_INT.

- primitive support for 2.00.
-
-Wed Mar 20 18:31:42 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * jump.c (duplicate_loop_exit_test): Make copy of contents of
- register note; if it was a REG_EQUAL note, it might have been an
- arbitrary expression and sharing it can cause problems in cse.
-
- * rtl.def (UMULT): Remove unsigned multiply code.

- support for indicating widening multiply with different modes
- on the MULT operation vs. its operands.

-
- * recog.c: Include insn-attr.h.
- (general_operand): If we have insn scheduling, don't allow paradoxical
- SUBREGs since they can prevent scheduling memory references; they
- aren't helpful on RISCs anyway and can cause poor register allocation.
- * Makefile.in (recog.o): Includes insn-attr.h.
-
- * cse.c (COST): A register only in NO_REGS isn't a specially-cheap reg.
- (simplify_unary_operation, case {ZERO,SIGN}_EXTEND): If OP_MODE was
- given as VOIDmode, use MODE; allow mode size of HOST_BITS_PER_INT.
- (cse_insn): Don't make SET_SRC equal SET_DEST if doing so will cause
- two registers to be live containing the same value.
- (cse_end_of_basic_block): Count SETs in CALL_INSNs and JUMP_INSNs.

- to copy BLKmode parm value. Save size and alignment for this.
-
- * gnulib2.c (__builtin_saveregs)[MIPS]: Go to text section.
-
- * final.c (final_scan_insn): Don't go to text after jump-tab label.
-
-Tue Mar 19 21:27:09 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)

- the table.
- (schedule_block): New variable TAIL_PRIORITY used to help determine

- done elsewhere.
- Call simplify_{unary,binary,ternary}_operation.
- Add cases involving logical and arithmetic operations applied
- to comparison operators or values with only one significant bit.
- Add more cases involving ABS since comparisons returning values
- can be done with ABS.
- Avoid generating (const (const ...) ...).
- Convert (xmult (x_extend ...) ...) to a widening multiply.
-
- (gen_rtx_combine): New function to search for an operation in

- *out-m68k.c (output_function_epilogue): Don't output
- anything if the epilogue was output as RTL. We detect this

- dwarfout.c needs some way of getting a unique numeric code for each
- type.
-
- * dwarfout.c (CLASSTYPE_*): Added some local default definitions
- for these macros in order to get around the fact that they are
- currently defined only in cplus-tree.h (and rms wants dwarfout.c

- to uses of the new gcc2 macro DECL_BIT_FIELD.
-
- * dwarfout.c (deriv_list_attribute): Fixed typo "decl" => "type".
-
- * dwarfout.c (output_dies_for_type): Replaced bogus reference to the
- non-existant routine "output_member_function_type_die" with a proper
- reference to the routine "output_subroutine_type_die".
-
- * dwarfout.c (output_symbols_for_block): Fixed calling error which

-
- * dwarfout.c: Replaced all uses of the obsolete macro STMT_SUBBLOCKS

- 20) was a little too drastic: If it succeded, no type info was
- emitted at all, which made for syntactically invalid stabs.
- Instead, just set 'full=0',

- a comparison tree that is a list of nested switch statements.
- Also, genrecog.c is now indented properly so that debugging is eased.
- (add_to_sequence): Enforce mode on the first arg of COMPARE, comparison
- operation, SIGN_EXTEND, and ZERO_EXTEND.

-
- * t-mips (CCLIBFLAGS, GNULIB2_CFLAGS): Define so that gnulib1
- and gnulib2 are both compiled with -G 0, in case the users compiles

- gnulib2 thinks they are in the small data section, because it only
- sees a pointer.

- (mips_fill_delay_slot): Instead of taking the number of nops as a
- parameter, take an enumeration, giving what kind of delay this is.
- If the next instruction is a label, put nops before label, not
- after. Add support for mflo/mfhi, which need 2 nops if the next
- instruction would modify the hi/lo registers.
- (mips_move_1word, mips_move_2words): mips_fill_delay_slot calling
- sequence changes. Pass mflo/mfhi to schedule nops.

- a double int for the HI:LO combination.
- (compute_frame_size): Don't set the initialized member until reload
- has completed, since otherwise the information may change.

- multiplies.
- (mulsi3): Break mul into it's two instructions, and schedule the
- two nops needed for the mflo instruction. Don't allow an integer
- multiplier anymore.
- (ffssi2): Delete define_expand, and use a second clobber'ed register

- (movdf define_split): Add a define_split to separate the two parts
- of DFmode register pairs when using GP registers.
- (mov??_internal): Change condition to call memory_operand, instead
- of just checking for MEM, which disallows (subreg (MEM)) during
- the intermediate parts of the compilation. Reported by
- lisa@MicroUnity.com.
- (negsi2): Turn back into a real insn instead of just a
- define_expand for subsi3.
- (one_cmplsi2): Turn back into a real insn instead of just a

- at the expense of potentially not moving the constant out of loops.
- (various): Add = constraint to all clobbers.
- (fix_trunc*): Go back to old method of using two clobbers, since
- unoptimized compiles call abort otherwise, when returning the result
- of truncating a float as a function result.
-
- * tm-mips.h (delay_type): New enum to express different types of
- delay slots.
- (mips_load_reg3, mips_load_reg4): Declarations for more registers
- to check for needing nops. Used by multiply/divide to schedule
- the two nops needed after mfhi/mflo if the next instruction would
- clobber the register.
- (CONDITIONAL_REGISTER_USAGE): If -msoft-float, disable all FP
- registers.
- (MASK_DEBUG_G): Add comment saying -mdebugg turns of new DImode
- patterns, in case the code is wrong.
- (HARD_REGNO_NREGS): All FP registers use register pairs, so that
- SF in a GP register takes only one register, and SI in a FP
- register takes 2.
- (HARD_REGNO_MODE_OK): Change macro to reference the array
- mips_hard_regno_mode_ok, which is now built in override_options.
- (CONST_OK_FOR_LETTER_P): 'N' is now for negative numbers, 'O' is
- an exact power of 2, and 'P' is now for positive numbers.
- (PREFERRED_RELOAD_CLASS): If -msoft-float, never prefer a FP
- register.
- (PREFERRED_RELOAD_CLASS_FM): Delete, since nobody uses it.
- (FINAL_PRESCAN_INSN): Check for mips_load_reg3 and mips_load_reg4
- being mentioned. Also add a missing tab when more than one delay
- slot.
- (CONST_COSTS): Make all constant ints cost 0 to lower register
- pressure according to Richard Kenner.
- (RTX_COSTS): Adjust costs for DI, SF, and DF modes, and add ABS/FFS
- costs as well.
- (REGISTER_MOVE_COSTS): Bump costs for moving between register
- classes, so that reload doesn't try to store int type values in the
- floating point registers.

-
- * c-typeck.c (build_binary_op_nodefault): Delete ERROR_CODE
- argument because it is always the same as CODE. Add new argument
- CONVERT_P, and call default_conversion on the operand trees if
- true. Rename to build_binary_op.

- popular machines that have a popular os, or given the os, it
- can sometimes figure out the vendor. Added in all the old
- ways of specifying machines from configure. Also added
- support for all (before it was missing a few) of the tm-*.h
- files. It now supports the concept of guessing the vendor for
- a given CPU type. It now supports the concept of guessing the
- os version given the vendor and/or the CPU type. Changed the
- default os for vax to ultrix, changed the default os for i386
- to sco.
-

-
- * mips-tfile.c (all): Change small allocation requests to use
- separate allocation and free functions, instead of using the word8
- union to hold each request. In order to support this easily, a free

- (main): If debugging, print a summary of the number of small
- allocations, frees, and the number of pages used.
- (add_procedure, copy_objects): Stuff the pointer to the end symbol

- create a vtable just because of -fdossier.
- * cp-gc.c: Each type points to an array of fields,
- instead of an array of pointers to fields. Ditto for methods.
- This saves one pointer per field or method by removing
- unneded extra indirection. Also other tweaks to save space.
- * cp-decl.c (init_decl_processing): Add length of
- field and method arrays to descriptors, instead of
- relying on NULL-termination (since we no longer have
- the extra pointer array).

- build_i_desc_overload and build_m_desc_overload.

- if none of the words are needed.
- (libcall_dead_p): Allow CALL to be in any part of PARALLEL.
- Use insn_dead_p to see if SET of return register is dead; old code

- Set cc0_live for a reference to CC0.
- Don't write REG_DEAD note if register is already dead or set in INSN.

- (even incomplete ones).
- (finish_struct, finish_enum): Don't create NULL-named

- `dwarfout_file_scope_decl' is called during final traversal of
- the chain of file-scope decls so that it is called also for
- file-scope TYPE_DECLs.
- (rest_of_decl_compilation): Deleted call to `dwarfout_file_scope_decl'
- for file-scope TYPE_DECLs; call `dwarfout_file_scope_decl' instead of

- whether it's defined; this permits compilation options to disable
- it, but leave it enabled by default. Add one to the array size,
- since the value retrieved appears to be the maximum index, not the
- true array size.

-
- * cp-pt.c (instantiate_class_template): has an argument to
- indicate whether to setup for parsing or not. (All existing cases
- did a feed input, but if we are trying to set up intermediate nodes
- while waiting for the parser to return to a template_instantiate
- site we need to suppress the parsing part of it, which will get
- redone later.)
- (tsubst): under case UNINSTANTIATED_P_TYPE, actually instantiate any
- class templates that are needed for function return values, and set
- them up as pending templates to be run later.
-
- * cp-parse.y (primary): since build_x_function_call doesn't
- require a complete type any more in certain cases, we instantiate
- any pending templates and then require_complete_type on the
- remainder.
-
- * cp-typeck.c (build_function_call_real): added an argument to
- optionally skip the require_complete_type... implicit template
- instantiation has to be postponed, so we won't get a complete type
- until the parser can grab it.
-
- * cp-call.c (build_overload_call_real): added an argument do
- allow choice of build_function_call_maybe or build_function_call
- based on whether we thought we would require a complete type out of
- build_function_call.
-

- processing a template declaration.
-
- * cp-tree.def: New node type, UNINSTANTIATED_P_TYPE, for
- parameterized types that haven't had parameters filled in yet.
- Looks like a type node.
-
- * cp-decl.c (struct binding_level): New flag indicating any name
- should be accepted when looked up at this level. This is a kludge
- to try to deal with methods of parameterized types.
- (declare_uninstantiated_type_level): Set it.
- (uninstantiated_type_level_p): Return it.
- * cp-class.c (pushclass): If the "class" type is
- UNINSTANTIATED_P_TYPE, flag it in the new binding level.
-
- * cp-decl.c (push_overloaded_decl): New argument to indicate
- whether the decl should be forgotten when the current level is
- exited. Callers changed.
- (push_overloaded_decl_top_level): Ditto.

- never forgets. Intended only for use by auto_function macro.
- (auto_function): Use it.
-
- * cp-decl.c (print_binding_level): Print type-shadowed field at

- * cp-decl.c (adjust_type_value): Use SET_IDENTIFIER_TYPE_VALUE,
- not set_identifier_type_value.
-
- * cp-decl.c (pushdecl): Undo Oct 4 back-out of previous change.
- Set type value of name of passed decl, instead of name of type in
- passed decl.
- (pushdecl_top_level): Search type-shadowed fields of outer binding
- levels, munging outermost one if found to cause it to "restore" the
- new global value.
-
- * cp-decl.c (push_overloaded_decl): Don't punt second or later
- templates of a given name.
-
- * cp-decl.c (start_decl): Template-handling code moved up, to
- cope better with variable declarations. Don't check for incomplete
- type or constructor requirements when processing template.
-
- * cp-decl2.c (build_push_scope): If passed error mark node, just
- return it.
- (constructor_name): Handle UNINSTANTIATED_P_TYPE.
-

- template name.
-
- * cp-method.c (report_type_mismatch): New magic bad-arg value -4
- indicates type unification failure.
- (build_overload_name, case UNINSTANTIATED_P_TYPE): Handle like other

- compiler.
-
- * cp-parse.y (template_type): Use IDENTIFIER_TYPE_VALUE from
- name, if expansion doesn't happen.

- from instantiate_class_template.
- (template_instantiation): Always put copy of decl in global scope.
- Use pushdecl_top_level instead of setting IDENTIFIER_GLOBAL_VALUE
- slot.
- (LC): If type has been or is being defined, push a new type with the
- same name, to avoid conflict.
- (try_for_typename): New type <itype>. Value is non-zero iff type to
- be pushed uses no template parms and isn't error_mark_node.
- (scoped_id): Return error_mark_node for template parameter uses, and
- leave error_mark_node alone. Only pop class if try_for_typename
- value is non-zero.
- (scoped_typename): Ditto.
-
- * cp-pt.c (end_template_decl): If template decl/class head arg is
- null, punt. For non-type templates that didn't come in as template
- decls, clear public flag. Such cases shouldn't arise any more; just
- put in abort call for now until we're sure. Comment out code for
- forcibly removing temporary values of template type parms; Michael
- broke the code and fixed the original problem. Handle error case
- where decl to be pushed might be null.
- (coerce_template_parms): Handle arg list as TREE_VEC as well as
- TREE_LIST. If arg list uses template parms, return
- UNINSTANTIATED_P_TYPE node.
- (uses_template_parms, case UNINSTANTIATED_P_TYPE): Return 1.
- (instantiate_class_template): Now returns tree -- error_mark_node or
- NULL_TREE or class type; callers and decls changed. Assign
- TYPE_NAME field when building new RECORD_TYPE and TYPE_DECL nodes.
- Don't need to do extra poplevel any more.
- (tsubst): Handle UNINSTANTIATED_P_TYPE, MINUS_EXPR, PLUS_EXPR,
- NEGATE_EXPR.

- field any more.

- setting type value field.

- error template node.
- (type_unification): Handle variadic functions, and functions with
- default values for arguments.
- (unify): Handle TREE_VEC and UNINSTANTIATED_P_TYPE.
-
- * cp-ptree.c (print_lang_type): Handle UNINSTANTIATED_P_TYPE.

- (CLASSTYPE_OFFSET*): Deleted.
- (CLASSTYPE_N_BASECLASSES): Now uses type's assoc. TYPE_BASETYPES

- sneaking it into the TREE_TYPE field of the basetypes.
-
- (ASSOC_TYPE): Deleted. Now use ASSOC_VALUE everywhere.
- (ASSOC_{BASETYPE,BASETYPES}): New macros. Both are operations on
- assocs and return assocs.
- (CLASS_ASSOC_BASETYPE): New macro. This performs roughly the same
- function that CLASSTYPE_BASECLASS used to, but it retains no assoc
- info in the type it returns.
- (ASSOC_NEXT_ASSOC): New macro used for traversing assoc chains built
- up by search routines.
- (ASSOC_VIA_{PUBLIC,VIRTUAL}): New macros for accessing inheritance
- information. CLASSTYPE_VIA_{PUBLIC,VIRTUAL} no longer used.

-
- * cplus-tree.c (build_classtype_variant): Deleted.

- describe the basetypes of T.
-
- * cplus-tree.c (make_lang_type): Always initialize

- virtual baseclasses, test CLASSTYPE_VBASECLASSES, not
- CLASSTYPE_VBASE_SIZE.
-
- * cplus-class.c (finish_struct): Rewritten to use assocs instead of
- types where appropriate.
-
- * cplus-search.c (get_base_distance): Change interface to use assocs
- or types. Also, PATH_PTR argument is now an assoc chain, not a

- types.
- (recursive_bounded_basetype_p): New function.
- (dfs_walk, dfs_* functions): Change to be called with assocs instead

- instead of types. Use macro ASSOC_VTABLE_PATH_MARKED on the assocs
- instead of CLASSTYPE_MARKED3. Use macro ASSOC_NEW_VTABLE_MARKED on
- the assocs instead of CLASSTYPE_MARKED4.
-
- * cplus-dbxout.c: Now needs to know more about assocs. When assocs
- are put in the TYPE_BASETYPEs field, it should not need to know
- about lang_type.
-
- * cplus-decl.c (xref_tag): Rewritten to build proper assoc lists. No
- longer builds basetype lists.
- (finish_function): Make `flag_no_inline' really take effect.
-
- * cplus-tree.c (make_assoc): Changed for new assoc structure. The
- fields in assocs are now: VALUE (pointer to TYPE that this assoc is
- for), OFFSET (the byte offset of this basetype in the whole object),
- VTABLE (the virtual function table that should be used to initialize
- objects controlled by this assoc), VIRTUALS (the virtual functions
- to use for initializing VTABLE), BASETYPES (a TREE_VEC of basetypes
- that this assoc has, or NULL_TREE if none), NEXT_ASSOC (a temporary
- slot used to point to the next assoc in an assoc chain),
- VIA_{PUBLIC,VIRTUAL} bits saying whether this assoc is a basetype of
- its parent via public or virtual inheritance.
-
- * cplus-ptree.c (print_lang_type): Modified as necessary to cope with
- new inheritance structure.
-
- * cplus-search.c (get_base_type_1): This function was unused and
- wrong. Deleted.

- (layout_vbasetypes): Ditto.
-
- * all cplus-* files: Removed dead code, unused variables, and change
- asserts where appropriate.
-
- * all cplus-* files: DECL_VIRTUAL_P is no longer used as a truth test
- for whether or not a function is virtual. Use a test for non-NULL
- DECL_VINDEX instead.

- template decl won't get discarded.
- Also deleted some commented-out code.
-
- * cplus-pt.c (uses_template_parms, cases VAR_DECL, FUNCTION_DECL):
- Give a warning if template parms are only used in places where they

-
- * toplev.c (rest_of_compilation):
- Save and restore DECL_INITIAL if we use save_for_inline_copying.
- * integrate.c (save_for_inline_copying): Really copy DECL_INITIAL.
- Calling integrate_decl_tree doesn't do it; deleted that call.
- (copy_decl_tree): New function.
-
- * integrate.c (integrate_decl_tree): Renamed from copy_decl_tree.
- (integrate_parm_decls): Renamed from copy_parm_decls.

-Sun Jul 21 06:43:23 1991 James Van Artsdalen (james at bigtex.cactus.org)
-
- * i386.md (tstsi): Add comment noting potential -m486 enhancement.
- (SImode push): With -m486, don't push from MEM.
- (addsi3): Don't use lea for three operand add if -m486.
- (ashlsi3): Don't use lea for shift of 1 if -m486.
- (zero_extendhisi2,zero_extendqihi2,zero_extendqisi2): If dest is
- %eax, or if -m486, AND is faster than MOVZX.
-
-Sun Jul 21 06:27:33 1991 Richard Kenner (kenner at vlsi1.ultra.nyu.edu)
-
- * expmed.c (store_fixed_bit_field): Pass actual bit position (including
- offset) to get_best_mode; also limit mode size to BITS_PER_WORD.
- Use failure of get_best_mode to indicate that field spans word
- boundary.

- (store_split_bit_field): Accept actual bit position, hence handing
- bitpos > BITS_PER_WORD.
- Abort if BITPOS and BITSIZE don't cross exactly one word boundary.
- Pass offset to store_fixed_bit_field; if register, use operand_subword;
- else adjust offset for second word.

-Sun Jul 21 06:11:55 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
-
- * All cplus-* files: DECL_VIRTUAL_P is no longer applied to
- FUNCTION_DECLs. Instead, to test if a function is virtual or not,
- it suffices to test whether its DECL_VINDEX is non-NULL. We use
- ERROR_MARK_NODE as the placeholder for a FUNCTION_DECL we know will
- be virtual, but for which we don't yet know the actual index.
-
- * cplus-decl.c (define_function): Don't set up DECL_ASSEMBLER_NAME
- until after having the chance to call through PFN. Since `pushdecl'
- now keys off of DECL_ASSEMBLER_NAME, we don't want to create
- inadvertent aliases between builtin and library functions.
-
- * cplus-typeck.c (build_modify_expr): We don't need to build a
- SAVE_EXPR for a WITH_CLEANUP_EXPR.

- Return 0 if NON_SAVING_SETJMP && `setjmp' is called in function.
-
- * tm-i386v.h (NON_SAVING_SETJMP): New macro.
- (FRAME_POINTER_REQUIRED): New macro.
-
-Sat Jul 20 12:25:56 1991 Richard Stallman (rms at mole.gnu.ai.mit.edu)

- * tm-m88k.h (OPTIMIZATION_OPTIONS): Don't change flag_signed_bitfields.
-
- * cccp.c (include_defaults) Use LOCAL_INCLUDE_DIR macro instead
- of "/usr/local/include". Provide default definition.
-
- * cccp.c (include_defaults) Added INCLUDE_DEFAULTS macro to
- provide complete control over default include directories.
- Delete the special case for VMS.
- * xm-vms.h (INCLUDE_DEFAULTS): Defined.
-
- * proto-man: Renamed from proto-unproto.1.
-
- * final.c (final_scan_insn): Do ASM_OUTPUT_LOOP_ALIGN only for real loop.
-
-Sat Jul 20 05:34:13 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
-
- * tree.h (tree_type): Use the MAXVAL slot for TYPE_METHODS.
- * cplus-class.c (finish_struct): Methods are now chained with
- TREE_CHAIN and placed in the TYPE_METHODS of their _TYPE node.
- * cplus-dbxout.c (dbxout_type_methods): Use this fact, instead of
- using more C++-specific knowledge.
-
- * cplus-decl.c (init_decl_processing): Variable
- `const_ptr_type_node' was not being initialized. Same with
- `const_string_type_node'.
-
- * tree.h (DECL_PRINT_NAME): Marked for death.
- (DECL_ASSEMBLER_NAME): Changed from a char* to a tree node.
- All front-end files changed as necessary.
-
- * cplus-tree.h (DECL_ORIGINAL_NAME): Deleted. Now we use
- DECL_NAME.
- (DECL_NAME): No longer means the mangled name. Now we use
- DECL_ASSEMBLER_NAME for that purpose.
- All cplus-* files changed as necessary.
-
- * cplus-tree.c (lang_printable_name): Use a ring-buffer to hold
- printable names instead of DECL_PRINT_NAME slot of a _DECL node.
-
- * collect2.c: #define COLLECT, and let config.h provide definition
- of macros.
-

-
- * mips.md (safe attribute): New attribute to indicate that the
- current insn is safe to fill a delay slot even if the register
- operand(s) are set in the load instruction which has the delay
- slot. This is for and/ior/xor expansions that have a large
- constant integer as operand[2]. The load of the constant can
- overlap the load.
- (andsi3, iorsi3, xorsi3): Replace logical define_insn's with
- define_expand's that either map directly to the hardware
- instruction, or have a clobbered register to load the large
- constant into. This is instead of using $1 to hold the

- where we need to load the integer. Add define_split's to break
- the large logical operations into the separate pieces.

- it to split the floating point value into a long integer, and
- print in out in hex. Otherwise use .float.
-

-
- * calls.c (stack_arg_under_construction): New variable.
- (store_one_arg): Set stack_arg_under_construction before calling
- expand_expr if expand_expr might call a constructor to initialize
- a stack argument.
- (expand_call): Push the stack around function calls if
- stack_arg_under_construction is nonzero.
- Also copy structure_value_addr in that case.
- Push the stack around an inline function if it makes calls
- and there are outgoing arguments on the stack which must be preserved.
- Move the call to expand_cleanups_to before that.
- Do this stack adjustment before computing argument locations.

- Thu Apr 16 12:23:06 1992 Mike Stump (mrs@rtl.cygnus.com)
-
- * cp-call.c (build_method_call): propagate const around to avoid an

-
- Wed Apr 15 14:18:27 1992 Mike Stump (mrs@rtl.cygnus.com)
-
- * cp-type2.c (readonly_warning_or_error): because the compiler

-
- Tue Apr 14 11:44:32 1992 Mike Stump (mrs@rtl.cygnus.com)

- to make what this points to const, but I don't have the heart

-
- * cp-decl2.c (grokclassfn): Don't use flag_this_is_variable
- to make what this points to const.

- (build_vtable): Use it.

-
- Thu Apr 9 03:45:03 1992 Mark Eichin (eichin at cygnus.com)
-
- * cp-class.c (finish_struct): sanity check before calling popclass.
- If we're already hosed due to previous parse errors (specifically,
- we're not inside a class anymore) just report an error rather than
- crashing in popclass (if there wasn't a previous parse error, as the
- message suggests, we should get reports; this closes gcc/p0000525.)
-
- Wed Apr 8 08:56:49 1992 Mike Stump (mrs@rtl.cygnus.com)
-
- * cp-decl.c (grokdeclarator): Fix an eichin bug introduced seconds
- ago. Shame, he didn't put:
-
- Workaround for p869:
- 1) grokdeclarator (around cp-decl.c:7462) is using popclass(1)
- uses popclass(1) to close the pushclass(3) done by
- build_push_scope; however, it's coming around another time and
- popping all the way out, which leads to the core dump when
- do_friend is called from global scope (do_friend uses
- current_class_name to figure out whose friendship it is
- bestowing.) Current workaround: if (friendp) don't allow
- popping all the way out. We still need to figure out how to
- make sure it only gets called the *right* time; we also need
- to figure out if the correct scope is being used, but that's a
- matter of regression testing.
-
- into a ChangeLog entry.
-

- (pushdecl): use set_identifier_type_value so that the local value
- actually gets erased when we leave this level. Changed code that
- checks for global_binding_level to recognize that if
- class_binding_level is set, we're not in the global one.
- (poplevel_class): restore shadowed list too, like poplevel does.
- (print_binding_level): added no_print_functions and

- directive.
- (ENCODE_SECTION_INFO): Encode function labels.
- (ASM_OUTPUT_LABELREF): Deal with function labels.

- now; their only use (saving stuff during profiling) interacts in a
- wierd way with required assembler directives at the start of a
- function. Instead, do the save and restore in the function
- prologue.
- (hppa_encode_label): Declare.
- * pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared
- libraries.
- (LINK_SPEC): Don't link against shared libraries if debugging or

- "ldil; add" sequences.

- Major rework to have caller-saves emit load/store double insns when
- possible and to avoid useless resaving of registers restored for
- source accesses only.
- * caller-save.c (toplevel): All arrays are multi-dimensional to
- hold information for multiple save/restore insns. New variable
- hard_regs_need_restore.
- (choose_hard_reg_mode): New argument `nregs' indicating how many
- hard registers are desired. All callers changed.
- (init_caller_save): Change initialization to handle multiple
- register saves. A call-used register can not be live across
- if we can not find a single register mode to save it in.
- (multiple register saves are optional)
- (init_save_areas): Change initialization of regno_save_mem to
- handle multiple register saves.
- (setup_save_areas): Allocate space for consecutive hard registers

- (save_call_clobbered_regs): Initialize hard_regs_need_restore.
- Set hard_regs_need_restore to hard_regs_saved after crossing
- a call. Also recompute n_regs_saved. At the end of a basic block

- (set_reg_live, clear_reg_live): Do the right thing for
- hard_regs_need_restore and hard_regs_saved.
- (restore_referenced_regs): Just return if X is a clobber.
- Test hard_regs_need_restore to determine when to restore a hard
- register from the save area.
- (insert_save_restore): Now returns the number of extra registers
- saved/restored. New argument `maxrestore' which constrains how
- many hard registers should be restored. All callers changed.
- Do stores of consecutive registers with double store insns if
- possible. Else do them with single word insns. Likewise for
- loads, except constrained by maxrestore. Set hard_regs_saved
- and hard_regs_need_restore appropriately to minimize useless
- saves into the save area. Test against hard_regs_need_restore
- when trying to restore multiple regs and similarly test against
- hard_regs_saved when storing multiple regs.

- (ASM_FINAL_SPEC): Use %U to get the last file name created with

- (ARG_POINTER_REGNUM): Use the hardwired register $0 as the

- pointer to be the same as the stack pointer after the initial
- stack allocations. This is to allow GCC generated code to be
- linked against MIPS shared libraries. The linker rearranges the

-
- * cp-decl.c (grokdeclarator): In SCOPE_REF case, sort out visibility

- nested classes of the class. This may be more of the solution to

-
- * cp-typeck.c (build_c_cast): Allow cast to array type in

-
- * cp-parse.y (print_parse_statistics): don't reference TOKEN_LENGTH

-
- * cp-init.c (build_vec_delete): Extract size of type even for
- destructorless types, so value can be computed to pass to delete

- alone, until we've figured out how to handle their interaction

- * cp-parse.y (template_instantiate_once): Temporarily set interface
- flags to `unknown' while processing member templates.
- * cp-decl.c (grokfndecl): Even if class vtable is getting written
- out, regardless of interface setting of class and write_virtuals
- flag, don't force virtual destructor of template class to be public.
- * cp-tree.h (struct pending_inline): New field `interface'.
- * cp-lex.c (do_pending_inlines): Restore interface flags from stored
- values, rather than calling extract_interface_info.

- slots here from the FINAL_PRESCAN_INSN macro.
-

- more.

- counted as statement separators.
-
- * collect2.c (scan_prog_file, OSF/rose case): Cast pointer arguments

-
-Fri May 7 04:48:25 1993 Chris Smith (csmith@convex.com)
-
- * x-convex (CCLIBFLAGS): Build libgcc1 with -tm c1 so it can't
- cause executables to become c2-only.
-
- * xm-convex.h: Remove workarounds for OS 8.0 no longer needed.
- (bcopy, bzero): Define to use memcpy and memset, to get them inlined.
-
- * convex[123*].h (CC1_SPEC, CPP_SPEC, LIB_SPEC): Move to convex.h.
-
- * convex.h (TARGET_FLAGS): Add -mvolatile-[no]cache.
- (TARGET_FLAGS, LONG_TYPE_SIZE): add -mlong{32,64}.
- (target_cpu): Define, enumeration for targets to use instead of flags.
- (TARGET_C34, TARGET_C38): Add. These don't schedule the same as C2.
- (OVERRIDE_OPTIONS): Call init routine in convex.c.
- (CPP_SPEC, ASM_SPEC, LINK_SPEC): If originally bootstrapped with
- an ieee compiler, produce an ieee gcc.
- (LINK_LIBGCC_SPECIAL): Define, to avoid searching old libgcc.a
- versions during bootstrap.
- (STACK_BOUNDARY): Change from 32 to 64 -- odd-word aligned
- longwords are slow on c34.
- (FUNCTION_PROLOGUE): Make frame size a multiple of 8, not 4.
- (FUNCTION_EPILOGUE): Output a 0 to terminate c34 icache prefetch.
- (INITIAL_FRAME_POINTER_OFFSET): Make a multiple of 8.
- (REG_ALLOC_ORDER): Define. Put S0 (the return register) last.
- (HARD_REGNO_MODE_OK): Rewrite to make clearer.
- (MODES_TIEABLE_P): Rewrite to make clearer.
- (PREFERRED_RELOAD_CLASS): Rewrite to make clearer.
- (S0_REGNUM, A0_REGNUM): Define.
- (*_REGNUM): Write in terms of [AS]0_REGNUM instead of absolute numbers.
- (enum reg_class, etc): Add SI_REGS == S_REGS + INDEX_REGS.
- (REGNO_REG_CLASS, REG_CLASS_FROM_LETTER, REGNO_OK_FOR_*_P): Use tables.
- (CONST_OK_FOR_LETTER_P): Change. New def passes any const_int,
- rejects any const_double.
- (CONST_DOUBLE_OK_FOR_LETTER_P): Change. New defs are 'G' == low
- word all zeros, 'H' == high word all signs.
- (EXTRA_CONSTRAINT): New. 'Q' == volatile memref. Used to generate
- cache-bypass instructions when -mvolatile-nocache is set.
- (RETURN_POPS_ARGS): Change, always true.
- (FUNCTION_ARG_ADVANCE): Count args, not # words of args.
- (FUNCTION_ARG): Return arg count to the final VOIDmode FUNCTION_ARG
- hack that supplies "next arg register" to be stored in call insn.

- (INITIALIZE_TRAMPOLINE): Use gen_call_pop.
- (LEGITIMATE_CONSTANT_P): Rewrite to make clearer.
- (GO_IF_LEGITIMATE_ADDRESS): Do not use indirect addressing -- with
- insn scheduling, two loads can be faster and can't be slower.
- (SLOW_BYTE_ACCESS): Define unless C2. Memory access to bytes is
- not actually slow, but faster processors don't forward partial
- word writes to word reads, and setting SLOW_BYTE_ACCESS
- makes the code consistently use word ops where possible.
- (CONST_COSTS): Const_DOUBLE cost is zero -- if it appears, it is
- immediate and therefore free.
- (RTX_COSTS): areg+const is free (via indexing).
- (RTX_COSTS): Provide target-dependent values for *,<<,>>
- (ADDRESS_COST): Zero. Indirect addresses are no longer used.
- (ADJUST_COST): Define.
- (TARGET_FLOAT_FORMAT): Define as VAX_FLOAT_FORMAT. Also
- accurately describes the semantics (not the bit pattern)
- of convex ieee mode.
- (REAL_VALUE_ATOF): Define, to prevent real.c from constructing
- vax dfloats. Apparently it doesn't do gfloat.
- (CHECK_FLOAT_VALUE): Call convex.c.
- (ASM_FILE_START): Output appropriate .fpmode pseudo op.
- (ASM_IDENTIFY_GCC): Ouput a zero after gcc2_compiled to keep it
- from hiding the real name from profilers and adb.
- (ASM_OUTPUT_DOUBLE, _FLOAT): Use hex to avoid /bin/as conversion
- errors.
- (ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
- (PRINT_OPERAND, _ADDRESS): Call convex.c.
- (EXIT_BODY): Define for libgcc2. Call atexit handler if present.
-
- convex.md: Add scheduling info.
- (movxx): One of the operands must be a register.
- (movdf, movdi): Add anonymous patterns that can load an arbitrary
- const_double by doing two immediate loads. This is not superior
- to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P
- still rejects these constants, but the patterns are still useful
- so rtx folding can produce arbitrary results.
- (floatunsdidf, floatunsdisf): Add patterns that avoid double rounding.
- (floatunssidf, floatunssisf): Add patterns that mimic gcc's default
- method, to keep SI cvts from promoting to the above DI cvts.
- (fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34
- cvtd.w is microcoded and slower.
- (addqi3, subqi3, mulqi3): can do immediate with word insn.
- (subsi3): use sub/neg to get reverse subtract (reduces reg shuffling).
- (udivsi3): give up on having sign_expand_binop do this; people keep
- breaking it. Manually extend unsigned SI to signed DI, then divide.
- (xshfxx3): The options rank differently on different machines, so
- spell them all out and enable the appropriate ones under TARGET_Cxx.
- (sqrtxx2): Put under flag_fast_math.
- (sinxx2, cosxx2): I don't know why these exist, but they do, so supply
- them. The other microcoded intrinsics are in convex math.h.
- (txtxx): Remove, no longer necessary.
- (cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch".
- (cmpqi): Omit, seems to produce marginally better cse than the old way.
- (cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is
- possible and would confuse old ucode.
- (movstrsi): Add.
- (anon): Add patterns to pick up on dbra optimizations and implement the
- sub/test part. (This optimizes out the compare against 0.)
- (call, call_value): Use _pop form instead, and let convex.c replace
- the pushes with fp stores.
- (end): Put local variable list back.
-
- convex.c (init_convex): New. Fill in tables used by convex.h.
- (psw_disable_float): New. Turn off float exception enables to
- make the environment more ieee-like.
- (set_cmp): Change name to output_cmp.
- (gen_cmp): Change name to output_condjmp. Add handling for
- `neg.x' as a fake `eq.x #0' and for optimized-out compares
- that read the carry of a preceding decrement.
- (simplify_for_convex): New. Replace addr-(-const) with
- addr+const so /bin/as will like the notation.
- (expand_movstr): New. Generate pipelined load/store sequence.
- (asm_declare_function_name): New. Output arg count for debuggers.
- (print_operand): Moved from convex.h. Add %u and %v to fetch
- subwords of a CONST_DOUBLE, %z to use in replacing shift by mul.
- (print_operand_address): Moved from convex.h.
- (outfloat): New, call REAL_VALUE_TO_DECIMAL.
- (replace_arg_pushes): New. Replace sp by fp if possible; this does
- not allow us to get rid of sp but stores are faster than pushes on
- new machines.
- (emit_ap_optimizations): New. Do simple live analysis of arg pointer
- register and eliminate dead reloads.
-
- math-convex.h: removed.
- fixinc.convex: new file.

-
- * cp-method.c (build_overload_nested_name): Use DECL_NAME instead of

- fix above errors", just exit quietly.
-
- * cp-lex.h (enum rid): Reordered for improved speed in grokdeclarator

- search path, since it's found by hand (as are RID_INT and RID_CHAR).
- (RID_FIRST_MODIFIER): Start at RID_EXTERN now.
-
- * cp-parse.y (overloaddef): Warn that using `overload' is an
- anachronism.
-
- Wed Dec 9 08:27:13 1992 Niklas Hallqvist (niklas at della.appli.se)

-
- * cp-call.c (build_method_call): Don't call abort for pure virtual

-
- * cp-call.c (convert_harshness): If parm's null for a reference (as

-
- * cp-decl.c (grokdeclarator): Make member initialization be a
- warning, not an error. Only issue it if not -pedantic, since
- grokfield will issue an error when pedantic. Only warn about
- constant members being initialized if `-ansi' is being used.
- (finish_decl): Only complain about uninitialized const's that aren't
- members when acting -pedantic, since we'll have already issued the
- error about initializing a field.
-
- * cp-type2.c (build_functional_cast): Revert change of Nov 2,

-
- * cp-method.c (icat): Handle an argument of `1' first, since it's
- the most common case.
-
- Tue Dec 1 02:36:28 1992 Mike Stump (mrs@cygnus.com)

-
- * c++ (-lm): Also recognize -lmath as a math library.
-
- * c++ (first): Only shift if $first is no, on the chance we got no
- arguments at all. If we didn't get anything, say so (since -lg++
- will fake out the gcc driver into thinking we want to do something).
-
- * cp-parse.y (paren_expr_or_null): New rule to emit an error when an
- empty condition is used when it shouldn't.
- (simple_if, stmt): Use it for `if', `while', and `do'.
-
- * cp-decl.c (start_decl): If grokdeclarator returns a
- void_type_node, return a NULL_TREE.
-
- * cp-typeck.c (build_modify_expr_1): When calling build_opfncall for
- `operator=', use make_node to create a plain NOP_EXPR for it to use,
- rather than trying to pass NOP_EXPR down hoping it gets there intact.
- (build_modify_expr): Ditto.
- * cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a
- MODIFY_EXPR, since it'll be coming in properly as a tree now.
-
- Sat Nov 21 02:33:28 1992 Brendan Kehoe (brendan@cygnus.com)
-
- * cp-init.c (expand_default_init): Clear DECL_REGISTER if we're
- going to call a ctor, otherwise we may end up generating bogus and
- confusing error messages about taking the addr of something declared
- to be `register'.
-
- * cp-typeck.c (build_x_function_call): Recognize a ptr-to-method
- that is being passed in as a function argument or as part of
- a COMPONENT_REF.

- same scope. Remove the pushdecl_class_level call since start_decl
- does the work now.
-
- Class scoping (and type value caching) redone. The new behaviour
- is triggered by NEW_CLASS_SCOPING being defined to 1. The old
- behavior is accomplished by defining it to the value 0. The entries
- below describes the effective changes when NEW_CLASS_SCOPING is set
- to non-zero.

- pushdecl_class_level.
- (globalize_nested_type): See to that both the class_shadowed and
- type_shadowed lists in the binding stack gets updated correctly.
- Don't call set_identifier_type_value on the DECL_NESTED_TYPENAME.
- Clear DECL_CLASS_CONTEXT as well as DECL_CONTEXT. Install a
- correct IDENTIFIER_{CLASS,TYPE}_VALUE if needed.
- (grokdeclarator): Prefer pushdecl_class_level over pushtag when
- recording a nested typedef.
- (build_enumerator): Don't install a method-local enumerator into

- instead of managing the IDENTIFIER_CLASS_VALUEs directly.
- (dfs_compress_decls): Adapted to recognize the envelopes
- dfs_pushdecls has installed in the IDENTIFIER_CLASS_VALUE slots.
- (push_class_decls): Tell overload_template_name to push the
- template decls into class scope instead of building a new level.
- Added code to open up the envelopes in closed_envelopes and
- install the class/type values in the class binding contour with
- proper shadowing.
- (dfs_popdecls): Removed.
- (pop_class_decls): Removed the actual decl-popping code, leaving
- just the obstack freeing pop_search_level call. The popping is
- automatically handled by poplevel now.
- * cp-tree.h (NEW_CLASS_SCOPING): A new macro constant defaulted to
- the value 1.
- (adjust_type_value): Prototype removed.
- (push_class_level_binding): Added prototype.

- this pointer) as artificial.

- classes.
-
- * cp-class.c (finish_struct): Don't play with TAIL when we're
- dealing with a TYPE_DECL of a RECORD_TYPE; the list continues on
- just fine, and TAIL is only used for managing FN_FIELDS.
-
- * cp-decl.c (pushlevel): Change cast to HOST_WIDE_INT.
- * cp-search.c (breadth_first_search): Likewise.
