This patch checks and sets bit_AVX2_Usable in __cpu_features.feature. * sysdeps/x86_64/multiarch/ifunc-defines.sym (COMMON_CPUID_INDEX_7): New. * sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): Check and set bit_AVX2_Usable. * sysdeps/x86_64/multiarch/init-arch.h (bit_AVX2_Usable): New macro. (bit_AVX2): Likewise. (index_AVX2_Usable): Likewise. (CPUID_AVX2): Likewise. (HAS_AVX2): Likewise.
