structure.  This smaller structure is however also passed in a few
calls to other functions, but the two same-but-different entities,
originally placed at the same offset and with the same size, confuse
the mechanism that takes care of handling call statements after
IPA-SRA.

I think that in stage 4 it is best to revert to GCC 12 behavior in this
particular case (when IPA-CP detects a constant in a single-field
structure or a single element array that is part of a bigger aggregate)
and the patch below does that.  If accepted, I plan to file a
missed-optimization bug to track that we could use the IPA-CP propagated
value to re-construct the small aggregate arguments.

OpenMP/Fortran: Fix loop-iter var privatization with !$OMP LOOP [PR108512]

For 'parallel', loop-iteration variables are marked are marked as 'private',
unless they either appear in an omp do/simd loop or an data-sharing clause
already exists for those on 'parallel'. 'omp loop' wasn't handled, leading
to (potentially) multiple data-sharing clauses in gfc_resolve_do_iterator
as omp_current_ctx pointed to the 'parallel' directive, ignoring the
in-betwen 'loop' directive.

The latter lead to a bogus diagnostic - or rather an ICE as the source
location var contained only '\0'.

powerpc: Fix up expansion for WIDEN_MULT_PLUS_EXPR [PR108787]

WIDEN_MULT_PLUS_EXPR as documented has the factor operands with
the same precision and the addend and result another one at least twice
as wide.
Similarly, {,u}maddMN4 is documented as
'maddMN4'
     Multiply operands 1 and 2, sign-extend them to mode N, add operand
     3, and store the result in operand 0.  Operands 1 and 2 have mode M
     and operands 0 and 3 have mode N.  Both modes must be integer or
     fixed-point modes and N must be twice the size of M.

     In other words, 'maddMN4' is like 'mulMN3' except that it also adds
     operand 3.

     These instructions are not allowed to 'FAIL'.

'umaddMN4'
     Like 'maddMN4', but zero-extend the multiplication operands instead
     of sign-extending them.
The PR103109 addition of these expanders to rs6000 didn't handle this
correctly though, it treated the last argument as also having mode M
sign or zero extended into N.  Unfortunately this means incorrect code
generation whenever the last operand isn't really sign or zero extended
from DImode to TImode.

The following patch removes maddditi4 expander altogether from rs6000.md,
because we'd need
        maddhd 9,3,4,5
        sradi 10,5,63
        maddld 3,3,4,5
        sub 9,9,10
        add 4,9,6
which is longer than
        mulld 9,3,4
        mulhd 4,3,4
        addc 3,9,5
        adde 4,4,6
and nothing would be able to optimize the case of last operand already
sign-extended from DImode to TImode into just
mr 9,3
        maddld 3,3,4,5
        maddhd 4,9,4,5
or so.  And fixes umaddditi4, so that it emits an add at the end to add
the high half of the last operand, fortunately in this case if the high
half of the last operand is known to be zero (i.e. last operand is zero
extended from DImode to TImode) then combine will drop the useless add.

If we wanted to get back the signed op1 * op2 + op3 all in the DImode
into TImode op0, we'd need to introduce a new tree code next to
WIDEN_MULT_PLUS_EXPR and maddMN4 expander, because I'm afraid it can't
be done at expansion time in maddMN4 expander to detect whether the
operand is sign extended especially because of SUBREGs and the awkwardness
of looking at earlier emitted instructions, and combine would need 5
instruction combination.

c++: Add testcases from some Issaquah DRs

The following patch adds testcases for 5 DRs.  In the DR2475, DR2530 and
CWG2691 my understanding is we already implement the desired behavior,
in DR2478 partially (I've added 2 dg-bogus there, I think we inherit
rather than overwrite DECL_DECLARED_CONSTINIT_P for explicit specialization
somewhere, still far better than clang++) and DR2673 on the other side the
DR was to codify the clang++ behavior rather than GCC.

Not 100% sure if it is better to commit the 2 with dg-bogus or just wait
until the actual fixes are implemented.  BTW, I've noticed

                    = DECL_SOURCE_LOCATION (fn);
                  DECL_DELETED_FN (clone)
                    = DECL_DELETED_FN (fn);

Fix possible sanopt compile-time hog

While working on bitmap operations I figured sanopt.cc uses
a sbitmap worklist, iterating using bitmap_first_set_bit on it.
That's quadratic since bitmap_first_set_bit for sbitmap is O(n).

The fix is to use regular bitmaps for the worklist and the bitmap
feeding it and to avoid a useless copy.

c++: fix ICE in joust_maybe_elide_copy [PR106675]

joust_maybe_elide_copy checks that the last conversion in the ICS for
the first argument is ck_ref_bind, which is reasonable, because we've
checked that we're dealing with a copy/move constructor.  But it can
also happen that we couldn't figure out which conversion function is
better to convert the argument, as in this testcase: joust couldn't
decide if we should go with

  operator foo &()

or

  operator foo const &()

so we get a ck_ambig, which then upsets joust_maybe_elide_copy.  Since
a ck_ambig can validly occur, I think we should just return early, as
in the patch below.

bpf: fix memory constraint of ldx/stx instructions [PR108790]

In some cases where the target memory address for an ldx or stx
instruction could be reduced to a constant, GCC could emit a malformed
instruction like:

    ldxdw %r0,0

Rather than the expected form:

    ldxdw %rX, [%rY + OFFSET]

This is due to the constraint allowing a const_int operand, which the
output templates do not handle.

Fix it by introducing a new memory constraint for the appropriate
operands of these instructions, which is identical to 'm' except that
it does not accept const_int.

Simplify "1 - bool_val" to "bool_val ^ 1"

For bool values, it is easier to deal with

we are more likely to simplify the xor further in many

asan: Add --param=asan-kernel-mem-intrinsic-prefix= [PR108777]

While in the -fsanitize=address case libasan overloads memcpy, memset,
memmove and many other builtins, such that they are always instrumented,
Linux kernel for -fsanitize=kernel-address recently changed or is changing,
such that memcpy, memset and memmove actually aren't instrumented because
they are often used also from no_sanitize ("kernel-address") functions
and wants __{,hw,}asaN_{memcpy,memset,memmove} to be used instead
for the instrumented calls.  See e.g. the https://lkml.org/lkml/2023/2/9/1182
thread.  Without appropriate support on the compiler side, that will mean
any time a kernel-address instrumented function (most of them) calls
memcpy/memset/memmove, they will not be instrumented and thus won't catch
kernel bugs.  Apparently clang 15 has a param for this.

bugfix, but given that -fsanitize=kernel-address has a single project that
uses it which badly wants this I think it would be worthwhile to make an
exception and get this into GCC 13 rather than waiting another year, it

vect: Make partial trapping ops use predication [PR96373]

PR96373 points out that a predicated SVE loop currently converts
trapping unconditional ops into unpredicated vector ops.  Doing
the operation on inactive lanes can then raise an exception.

As discussed in the PR trail, we aren't 100% consistent about
whether we preserve traps or not.  But the direction of travel
is clearly to improve that rather than live with it.  This patch

A similar problem applies to fsubr_1.c.

I think this is likely to regress Power 10, since conditional

rs6000/test: Adjust some test cases on partial vector [PR96373]

As Richard pointed out in [1] and the testing on Power10, the
proposed fix for PR96373 requires some updates on a few rs6000
test cases which adopt partial vector.  This patch is to fix

lra: Replace subregs in bare uses & clobbers [PR108681]

In this PR we had a write to one vector of a 4-vector tuple.
The vector had mode V1DI, and the target doesn't provide V1DI
moves, so this was converted into:

    (clobber (subreg:V1DI (reg/v:V4x1DI 92 [ b ]) 24))

followed by a DImode move.  (The clobber isn't really necessary
or helpful for a single word, but would be for wider moves.)

The subreg in the clobber survived until after RA:

    (clobber (subreg:V1DI (reg/v:V4x1DI 34 v2 [orig:92 b ] [92]) 24))

IMO this isn't well-formed.  If a subreg of a hard register simplifies
to a hard register, it should be replaced by the hard register.  If the
subreg doesn't simplify, then target-independent code can't be sure
which parts of the register are affected and which aren't.  A clobber
of such a subreg isn't useful and (again IMO) should just be removed.
Conversely, a use of such a subreg is effectively a use of the whole
inner register.

LRA has code to simplify subregs of hard registers, but it didn't
handle bare uses and clobbers.  The patch extends it to do that.

One question was whether the final_p argument to alter_subregs
should be true or false.  True is IMO dangerous, since it forces
replacements that might not be valid from a dataflow perspective,
and uses and clobbers only exist for dataflow.  As said above,
I think the correct way of handling a failed simplification would
be to delete clobbers and replace uses of subregs with uses of
the inner register.  But I didn't want to write untested code
to do that.

In the PR, the clobber caused an infinite loop in DCE, because
of a disagreement about what effect the clobber had.  But for
the reasons above, I think that was GIGO rather than a bug in
DF or DCE.

tree-optimization/28614 - high FRE time for gcc.c-torture/compile/20001226-1.c

I noticed that for gcc.c-torture/compile/20001226-1.c even -O1 has

stop after the second.  The function is also called repeatedly for

IBM zSystems: Do not propagate scheduler state across basic blocks [PR108102]

So far we propagate scheduler state across basic blocks within EBBs and
reset the state otherwise.  In certain circumstances the entry block of
an EBB might be empty, i.e., no_real_insns_p is true.  In those cases
scheduler state is not reset and subsequently wrong state is propagated
to following blocks of the same EBB.

Since the performance benefit of tracking state across basic blocks is
questionable on modern hardware, simply reset the state for each basic
block.

ifcvt: Fix regression in aarch64/fcsel_1.c

{
  if (a > b)
    return c;
  else
    return d;
}

which started failing in the GCC 12 timeframe.  When it passed,
the RTL had the form:

[A]
  (set (reg ret) (reg c))
  (set (pc) (if_then_else (gt ...) (label_ref ret) (pc)))
    edge to ret, fallthru to else
else:
  (set (reg ret) (reg d))
    fallthru to ret
ret:
  ...exit...

i.e. a branch around.  Now the RTL has form:

[B]
  (set (reg ret) (reg d))
  (set (pc) (if_then_else (gt ...) (label_ref then) (pc)))
    edge to then, fallthru to ret
ret:
  ...exit...

then:
  (set (reg ret) (reg c))
    edge to ret

i.e. a branch out.

Both are valid, of course, and there's no easy way to predict
which we'll get.  But ifcvt canonicalises its representation on:

  if (cond) goto fallthru else goto non-fallthru

That is, it canoncalises on the branch-around case for half-diamonds.
It therefore wants to invert the comparison in [B] to get:

  if (...) goto ret else goto then

But that isn't possible for strict FP gt, so the optimisation fails.

Canonicalising on the branch-around case seems like the wrong choice for
half diamonds.  The natural way of expressing a conditional branch is
for the label_ref to be the "then" destination and pc to be the "else"
destination.  And the natural choice of condition seems to be the one
under which extra stuff *is* done, rather than the one under which extra
stuff *isn't* done.  But that decision goes back at least 20 years and
it doesn't seem like a good idea to change it in stage 4.

This patch instead allows the internal structure to store the
condition in inverted form.  For simplicity it handles only
conditional moves, which is the one case that is needed

When the architecture adds pre-processing to `define_insn "adddi3"`, such as
`define_expend "adddi3"`, the gen_expand will be automatically called here,
causing the patern to emit directly, which will cause insn to enter REG_NOTE
for `DWARF` instead of patern.

The following error REG_NOTE occurred:
error: invalid rtl sharing found in the insn:
