Hi all,

The initial patch for AVX10.2 has been merged this week.

For the upcoming patches, we will first upstream ymm rounding control part.

In ymm rounding part, ALL the instructions in AVX512 with 512-bit rounding
control will also have 256-bit rounding control in AVX10.2.

For clearness, the patch order is based on alphabetical order. Each patch
will include its intrin definition and related tests. Sometimes pattern is
not changed in the patch because the previous change in the patch series
has already enabled the 256 bit rounding in the pattern.

Bootstrapped on x86-64-pc-linux-gnu. Ok for trunk?

Thx,
Haochen

It seems that the patch series somehow corrupted.

Therefore, I have uploaded a vendor branch for all the patches for anyone interested:
https://gcc.gnu.org/git/?p=gcc.git;a=shortlog;h=refs/vendors/ix86/heads/avx10.2

Thx,
Haochen
