[rs6000] PR89338, PR89339: Fix compat vector intrinsics for BE and 32-bit
Test FAILS: sse2-cvtpd2dq-1, sse2-cvtpd2ps, sse2-cvttpd2dq on powerpc64
(big-endian).
_mm_cvtpd_epi32, _mm_cvtpd_ps, _mm_cvttpd_epi32: Type conversion from
vector doubleword type to vector word type leaves the results in even
lanes in big endian mode.
Test FAILS: sse-cvtss2si-1, sse-cvtss2si-2, sse-movmskb-1 on powerpc
(32-bit big-endian).
Incorrect type for interpreting the result from mfvsrd instruction leads
to incorrect results. Also, mfvsrd instruction only works as expected in
64-bit mode or for 32-bit quantities in 32-bit mode. A more general,
if slower, solution is needed for 32-bit mode.

AArch64: Fix command line options canonicalization version #2. (PR target/88530)
Commandline options on AArch64 don't get canonicalized into the smallest
possible set before output to the assembler. This means that overlapping feature
sets are emitted with superfluous parts.
Normally this isn't an issue, but in the case of crypto we have retro-actively
split it into aes and sha2. We need to emit only +crypto to the assembler
so old assemblers continue to work.
Because of how -mcpu=native and -march=native work they end up enabling all
feature bits. Instead we need to get the smallest possible set, which would also
fix the problem with older the assemblers and the retro-active split.
The function that handles this is called quite often. It is called for any
push/pop options or attribute that changes arch, cpu etc. In order to not make
this search for the smallest set too expensive we sort the options based on the
number of features (bits) they enable. This allows us to process the list
linearly instead of quadratically (Once we have enabled a feature, we know that
anything else that enables it can be ignored. By sorting we'll get the biggest
groups first and thus the smallest combination of commandline flags).
The Option handling structures have been extended to have a boolean to indicate
whether the option is synthetic, with that I mean if the option flag itself
enables a new feature.
e.g. +crypto isn't an actual feature, it just enables other features, but others
like +rdma enable multiple dependent features but is itself also a feature.
There are two ways to solve this.
1) Either have the options that are feature bits also turn themselves on, e.g.
change rdma to turn on FP, SIMD and RDMA as dependency bits.
2) Make a distinction between these two different type of features and have the
framework handle it correctly.
Even though it's more code I went for the second approach, as it's the one
that'll be less fragile (people can't forget it) and gives the least surprises.
Effectively this patch changes the following:
The values before the => are the old compiler and after the => the new code.
-march=armv8.2-a+crypto+sha2 => -march=armv8.2-a+crypto
-march=armv8.2-a+sha2+aes => -march=armv8.2-a+crypto
The remaining behaviors stay the same.

Handle stack pointer with SUBS/ADDS instructions.
In general the stack pointer was not handled for many SUBS/ADDS patterns in
aarch64.md.
Both the "extended register" and "immediate" forms allow the stack pointer to be
used as the source register, while no form allows the stack pointer for the
destination register.
The define_insn patterns generating ADDS/SUBS did not allow the stack pointer
for any operand, while the define_peephole2 patterns that generated RTX to be
matched by these patterns allowed the stack pointer for any operand.
The patterns are fixed by adding the 'k' constraint for the first source operand
to all define_insns that generate the ADDS/SUBS "extended register" and
"immediate" forms (but not the "shifted register" form).
In peephole optimizations, constraint strings are ignored (see "(gccint) C
Constraint Interface" info node in the documentation), so the decision to act or
not is based solely on the predicate and condition.
This patch introduces a new predicate "aarch64_general_reg" to be used in
define_peephole2 patterns where only GENERAL_REGS registers are acceptable and
uses that predicate in the peepholes that generate patterns for ADDS/SUBS.
Full bootstrap and regtest done on aarch64-none-linux-gnu.
Regression tests done on aarch64-none-linux-gnu and aarch64-none-elf cross
compiler.

which is in the fake loop that contains the whole function, instead of
generating one
vxorp[ds] %xmmN, %xmmN, %xmmN
for each SF/DF conversion.
NB: The LCM algorithm isn't appropriate here since it may place a vxorps
inside the loop. Simple testcase show this:
$ cat badcase.c
extern float f;
extern double d;
void
foo (int n, int k)
{
for (int j = 0; j != n; j++)
if (j < k)
d = f;

It generates

loop:
if(j < k)
vxorps %xmm0, %xmm0, %xmm0
vcvtss2sd f(%rip), %xmm0, %xmm0
...

...
This is because LCM only works when there is a certain benifit. But for
conditional branch, LCM wouldn't move

[GCC, AArch64] Fix a couple of bugs in BTI
While doing more testing I found a couple of issues with my BTI patches.
This patch fixes them:
1) Remove a reference to return address key. The original patch was written
based on a different not yet committed patch ([PATCH 3/3][GCC][AARCH64] Add
support for pointer authentication B key) and I missed out on cleaning this
up. This is hidden behind the configuration option and thus went unnoticed.
2) Add a missed case for adding the BTI instruction in thunk functions.

PR libstdc++/89416 fix __is_move_insertable trait
The common base class for __is_move_insertable and __is_copy_insertable
instantiates both the copy and move tests, when only one is needed. The
unneeded one might cause errors outside the immediate context.
The solution used in this patch is to replace them with alias templates,
which will only be instantiated as needed.

PR c++/88690 - C++17 ICE with empty base in aggregate.
Base fields for empty bases appear in initialization order, which may not be
the same as layout order. If they also show up in a CONSTRUCTOR in that
order, output_constructor_regular_field aborts because it understandably
doesn't want to go backwards. I also considered making o_c_r_f more
tolerant of the case where the out-of-order field has fieldsize 0, and so no
actual data needs to be emitted, but we might as well avoid adding an
element to the CONSTRUCTOR in the first place.

PR c++/87921 - wrong error with inline static data member.
c_parse_final_cleanups checks DECL_IN_AGGR_P to avoid trying to emit a
static data member that has not been defined. The inline variable patch
changed that to exempt inline variables. But in this case we haven't
instantiated the variable yet, so we really don't have a definition. This
patch changes inline variable handling such that DECL_IN_AGGR_P is not set
for a defined inline variable, so we can remove all the checks of
DECL_INLINE_VAR_P after DECL_IN_AGGR_P.
With that change we were failing on a static data member that had been
instantiated due to a use before we got around to processing it in
instantiate_class_template; we should detect that and avoid all the
finish_static_data_member_decl processing, which assumes that it is the
first time we're seeing the variable.
