Lu --- Since this type typedef struct { unsigned char v __attribute__((aligned(256))) __attribute__ ((vector_size(64 * sizeof(unsigned char)))); } stress_vec_u8_64_t; is processed outside of the function and AVX512 is enabled by default, it has V64QImode instead of BLKmode. If the target attribute disables AVX512, V64QImode becomes unusable.=
