              * Makefile.in (OBJS): Add alias.o
              (alias.o): Add dependencies.
              * alias.c: New file.
              * sched.c: Remove alias analysis code.  It lives in alias.c now.
              (reg_last_uses_size): Declare.
              (sched_analyze_2): Add new arguments to true_dependence.
              (sched_analyze_insn): Use reg_last_uses_size instead of max_reg.
              (schedule_block): Initialize reg_last_uses_size.
              (schedule_insns): Always call init_alias_analysis.
              * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
              mark return value from such functions as a pointer and keep track of
              them for alias analysis.  If a return value from a function is a
              pointer, mark it as such.
              * combine.c (distribute_notes): Handle REG_NOALIAS.
              * cse.c (struct write_data): Delete.  No longer needed.
              (invalidate): Don't call set_nonvarying_address_components anymore.
              Use true_dependence to decide if an entry should be removed from
              the hash table.
              (invalidate_memory): Remove WRITES argument, simplify appropriately.
              Fix all callers.
              (note_mem_written): Similarly for WRITE_PTR argument.
              (invalidate_from_clobbers): Similarly for W argument.
              (invalidate_for_call): Remove memory elements from the hash table.

              (cse_rtx_varies_p): New function.  Derived from old
              cse_rtx_addr_varies_p.
              (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
              Don't call note_mem_written anymore.  Stack pushes invalidate the stack
              pointer if PUSH_ROUNDING is defined.  No longer need to call
              cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
              (skipped_writes_memory): Remove variable.
              (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.

              to true_dependence.
              (memref_referenced_p): Likewise.
              * loop.c (NUM_STORES): Increase to 30.
              (prescan_loop): Only non-constant calls set unknown_address_altered.
              (invariant_p): Add new arguments to true_dependence.
              (record_giv): Initialize unrolled and shared fields.
              (emit_iv_add_mult): Call record_base_value as needed.
              * loop.h (struct induction): Add unrolled and shared fields.

              if we have multiple address GIVs that were combined with the same
              dst_reg GIV.  Note when a new register is created due to unrolling.
              * rtl.c (reg_note_name): Add REG_NOALIAS.
              * rtl.h (enum reg_note): Similarly.
              (rtx_varies_p, may_trap_p, side_effects_p): Declare.
              (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
              (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
              (true_dependence, read_dependence, anti_dependence): Likewise.
