When making patch to replace TARGET_P8_VECTOR, I noticed
for *eqv<BOOL_128:mode>3_internal1 unlike the other logical
operations, we only exploited the vsx version.  I think it
is an oversight, this patch is to consider veqv as well.

gcc/ChangeLog:

	* config/rs6000/rs6000.md (*eqv<BOOL_128:mode>3_internal1): Generate
	insn veqv if TARGET_ALTIVEC and operands are altivec_register_operand.

When working to get rid of mask bit OPTION_MASK_P8_VECTOR,
I noticed that the check on ISA_3_0_MASKS_IEEE is actually
to check TARGET_P9_VECTOR, since we check all three mask
bits together and p9 vector guarantees p8 vector and vsx
should be enabled.  So this patch is to adjust this first
as preparatory patch for the following patch to change
all uses of OPTION_MASK_P8_VECTOR and TARGET_P8_VECTOR.

gcc/ChangeLog:

	* config/rs6000/rs6000-cpus.def (ISA_3_0_MASKS_IEEE): Remove.
	* config/rs6000/rs6000.cc (rs6000_option_override_internal): Replace
	ISA_3_0_MASKS_IEEE check with TARGET_P9_VECTOR.

When I was making a patch to rework TARGET_P8_VECTOR, I
noticed that there are some redundant checks and dead code
related to TARGET_DIRECT_MOVE, so I made this patch as one
separated preparatory patch, it consists of:
  - Check either TARGET_DIRECT_MOVE or TARGET_P8_VECTOR only
    according to the context, rather than checking both of
    them since they are actually the same (TARGET_DIRECT_MOVE
    is defined as TARGET_P8_VECTOR).
  - Simplify TARGET_VSX && TARGET_DIRECT_MOVE as
    TARGET_DIRECT_MOVE since direct move ensures VSX enabled.
  - Replace some TARGET_POWERPC64 && TARGET_DIRECT_MOVE as
    TARGET_DIRECT_MOVE_64BIT to simplify it.
  - Remove some dead code guarded with TARGET_DIRECT_MOVE
    but the condition never holds here.

gcc/ChangeLog:

	* config/rs6000/rs6000.cc (rs6000_option_override_internal): Simplify
	TARGET_P8_VECTOR && TARGET_DIRECT_MOVE as TARGET_P8_VECTOR.

While testing future 64-bit location_t support, I ran into an
-fcompare-debug issue that was traced back here. Despite the name,
next_discriminator_for_locus() is meant to take an integer line number
argument, not a location_t. There is one call site which has been passing a
location_t instead. For the most part that is harmless, although in case
there are two CALL stmts on the same line with different location_t, it may
fail to generate a unique discriminator where it should. If/when location_t
changes to be 64-bit, however, it will produce an -fcompare-debug
failure. Fix it by passing the line number rather than the location_t.

I am not aware of a testcase that demonstrates any observable wrong
behavior, but the file debug/pr53466.C is an example where the discriminator
assignment is indeed different before and after this change.

	* tree-cfg.cc (assign_discriminators): Fix incorrect value passed to

As reported in bug 114266, GCC fails to pedwarn for a compound
literal, whose type is an array of unknown size, initialized with an
empty initializer.  This case is disallowed by C23 (which doesn't have
zero-size objects); the case of a named object is diagnosed as
expected, but not that for compound literals.  (Before C23, the
pedwarn for empty initializers sufficed.)  Add a check for this
specific case with a pedwarn.

On i686 PR116587 test compilation resulted in LRA failure to find
registers for a reload insn pseudo.  The insn requires 6 regs for 4
reload insn pseudos where two of them require 2 regs each.  But we
have only 5 free regs as sp is a fixed reg, bp is fixed because of
-fno-omit-frame-pointer, bx is assigned to pic_offset_table_pseudo
because of -fPIC.  LRA spills pic_offset_table_pseudo as the last
chance approach to allocate registers to the reload pseudo.  Although
it makes 2 free registers for the unallocated reload pseudo requiring
also 2 regs, the pseudo still can not be allocated as the 2 free regs
are disjoint.  The patch spills all pseudos conflicting with the
unallocated reload pseudo including already allocated reload insn
pseudos, then standard LRA code allocates spilled pseudos requiring
more one register first and avoid situation of the disjoint regs for
reload pseudos requiring more one reg.

This fixes a few aarch64 specific testcases after the move to default to GNU C23.
For the SME testcases, the GNU C23 cases as `()` changing to mean `(void)` instead
of a non-prototype declaration; the non-prototype declaration merging was confusing
some of the time so the updated way is the expected way even for that.
For pic-*.c `-Wno-old-style-definition` was added not to warn about old style definitions.
For pr113573.c, I added `-std=gnu17` since I was not sure if `(...)` with C23 would invoke
the same issue.

reuse_rtx is not documented nor the format to use it is ever documented.
So it should not be supported for the .md files.

This also fixes the problem if an invalid index is supplied for reuse_rtx,
instead of ICEing, put out a real error message.  Note since this code
still uses atoi, an invalid index can still be used in some cases but that is
recorded as part of PR 44574.

Note I did a grep of the sources to make sure that this was only used for
the read rtl in the GCC rather than while reading in .md files.

This patch adds C++ support for the `dispatch` construct and the `adjust_args`
clause. It relies on the c-family bits comprised in the corresponding C front
end patch for pragmas and attributes.

Additional C/C++ common testcases are provided in a subsequent patch in the
series.

This patch adds middle-end support for the `dispatch` construct and the
`adjust_args` clause. The heavy lifting is done in `gimplify_omp_dispatch` and
`gimplify_call_expr` respectively. For `adjust_args`, this mostly consists in
emitting a call to `omp_get_mapped_ptr` for the adequate device.

For dispatch, the following steps are performed:

* Handle the device clause, if any: set the default-device ICV at the top of the
dispatch region and restore its previous value at the end.

* Handle novariants and nocontext clauses, if any. Evaluate compile-time
constants and select a variant, if possible. Otherwise, emit code to handle all
possible cases at run time.

This patch introduces the OMP_DISPATCH tree node, as well as two new clauses
`nocontext` and `novariants`. It defines/exposes interfaces that will be
used in subsequent patches that add front-end and middle-end support, but
nothing generates these nodes yet.
