Subject: x86: exclude certain ISA extensions from v3/v4 ISA
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a98600052eb680249abae0083a7c24d7e57f7379;p=binutils-gdb.git

x86: exclude certain ISA extensions from v3/v4 ISA

Like TBM and LWP, XOP and FMA4 also shouldn't be included in v3.

Like AVX512-4VNNIW, AVX512-4FMAPS also shouldn't be included in v4.
