    • [rs6000] PR89338, PR89339: Fix compat vector intrinsics for BE and 32-bit · db739d3c 
      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) · 4ca82fc9 
      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.
