Hi all,
Since AVX10 is the first major ISA introduced after AVX-512, we propose
to add target_clones support for it.
Although AVX10.1-256 won't cover 512-bit part of AVX512F, but since
it is only for priority but not for implication, it won't be an issue.
Bootstrapped and regtested on x86_64-pc-linux-gnu. Ok for trunk and backport
to GCC14?
Thx,
hAOCHEN
gcc/ChangeLog:
* common/config/i386/i386-common.cc: Change Granite Rapids
series CPU type to P_PROC_AVX10_1_512.
* common/config/i386/i386-cpuinfo.h (enum feature_priority):
Revise comment part. Add P_AVX10_1_256, P_AVX10_1_512,
P_PROC_AVX10_1_512.
* common/config/i386/i386-isas.h: Link to avx10.1-256, avx10.1-512.
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx10_1-25.c: New test.
* gcc.target/i386/avx10_1-26.c: Ditto.
