--- Comment #5 from Uroš Bizjak <ubizjak at gmail dot com> ---
_mm_loadu_si64 intrinsic can now be used in the example from #Description:
#include <immintrin.h>
#include <stdint.h>
__m256 load_bytes_to_m256(uint8_t *p)
{
__m128i small_load = _mm_loadu_si64( (void *)p );
__m256i intvec = _mm256_cvtepu8_epi32( small_load );
return _mm256_cvtepi32_ps(intvec);
}
-O2 -mavx2 now compiles on 32bit targets to:
...
vpmovzxbd (%eax), %ymm0
vcvtdq2ps %ymm0, %ymm0
