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.

AArch64: Update Armv8.4-a's FP16 FML intrinsics
This patch updates the Armv8.4-a FP16 FML intrinsics's suffixes from u32 to f16
to be more consistent with the naming convention for intrinsics.
The specifications for these intrinsics have not been published yet so we do
not need to maintain the old names.
The patch was created with the following script:
grep -lIE "(vfml[as].+)_u32" -r gcc/ | grep -iEv ".+Changelog.*" \
| xargs sed -i -E -e "s/(vfml[as].+)_u32/\1_f16/g"

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.
OK for trunk?

With -mavx, for
$ cat foo.i

void
foo (void)
{

f = i;
}
we need to generate

...
vcvtss2sd f(%rip), %xmmN, %xmmX
...
vcvtsi2ss i(%rip), %xmmN, %xmmY
to avoid partial XMM register stall. This patch adds a pass to generate
a single
vxorps %xmmN, %xmmN, %xmmN
at entry of the nearest dominator for basic blocks with SF/DF conversions,
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
...
loopend
...
This is because LCM only works when there is a certain benifit. But for
conditional branch, LCM wouldn't move
vxorps %xmm0, %xmm0, %xmm0
out of loop. SPEC CPU 2017 on Intel Xeon with AVX512 shows:

[arm] Add support for Neoverse N1
This patch adds support for the Neoverse N1 [1]. This CPU was previously supported through the Ares codename.
-mcpu=ares is retained as an alias of the new -mcpu=neoverse-n1.
Bootstrapped and tested on arm-none-linux-gnueabihf.
* config/arm/arm-cpus.in (ares): Rename to...
(neoverse-n1): ... This. Add ares as alias.
* config/arm/arm-tables.opt: Regenerate.

[AArch64] Add support for Neoverse N1
This patch adds support for the Neoverse N1 CPU [1]. This was supported in GCC earlier through the codename Ares,
which it now replaces. -mcpu=ares is still accepted as there's been a binutils release supporting it,
but the internal structures are renamed to use Neoverse N1-related identifiers.

PR c++/87685 - generic lambda 'this' capture error.
The standard says that in a generic lambda we should speculatively capture
'this' if we see a call to an overload set that contains a non-static member
function, but it seems wrong to reject the program if we can't capture,
since it might not actually be needed.
