Subject: [PATCH] x86-64: Require BMI2 for __strlen_evex and __strnlen_evex
Content-type: text/plain; charset=UTF-8
Since __strlen_evex and __strnlen_evex added by
commit 1fd8c163a83d96ace1ff78fa6bac7aee084f6f77

x86-64: Add ifunc-avx2.h functions with 256-bit EVEX
use sarx:
c4 e2 6a f7 c0 sarx %edx,%eax,%eax
require BMI2 for __strlen_evex and __strnlen_evex in ifunc-impl-list.c.
ifunc-avx2.h already requires BMI2 for EVEX implementation.
