Here is the commit message I am checking in: --- Since __strlen_evex and __strnlen_evex added by commit 1fd8c163a83d96ace1ff78fa6bac7aee084f6f77 Author: H.J. Lu Date: Fri Mar 5 06:24:52 2021 -0800 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. --- Thanks. -- H.J.
