H.J. Lu 5f3d0b78e0 Use AVX unaligned memcpy only if AVX2 is available ... memcpy with unaligned 256-bit AVX register loads/stores are slow on older processorsl like Sandy Bridge. This patch adds bit_AVX_Fast_Unaligned_Load and sets it only when AVX2 is available. [BZ #17801] * sysdeps/x86_64/multiarch/init-arch.c (__init_cpu_features): Set the bit_AVX_Fast_Unaligned_Load bit for AVX2. * sysdeps/x86_64/multiarch/init-arch.h (bit_AVX_Fast_Unaligned_Load): New. (index_AVX_Fast_Unaligned_Load): Likewise. (HAS_AVX_FAST_UNALIGNED_LOAD): Likewise. * sysdeps/x86_64/multiarch/memcpy.S (__new_memcpy): Check the bit_AVX_Fast_Unaligned_Load bit instead of the bit_AVX_Usable bit. * sysdeps/x86_64/multiarch/memcpy_chk.S (__memcpy_chk): Likewise. * sysdeps/x86_64/multiarch/mempcpy.S (__mempcpy): Likewise. * sysdeps/x86_64/multiarch/mempcpy_chk.S (__mempcpy_chk): Likewise. * sysdeps/x86_64/multiarch/memmove.c (__libc_memmove): Replace HAS_AVX with HAS_AVX_FAST_UNALIGNED_LOAD. * sysdeps/x86_64/multiarch/memmove_chk.c (__memmove_chk): Likewise.		2015-01-30 15:37:58 -08:00
