VPTESTMD - Packed TEST Mask Dword
VPTESTMD k1{k2}, xmm2, xmm3/m128/m32bcst (V5+VL
__mmask8 _mm_test_epi32_mask(__m128i a, __m128i b)
__mmask8 _mm_mask_test_epi32_mask(__mmask8 k2, __m128i a, __m128i b)
For each DWORD, calculate bitwise (1) & (2), if any bit of the result is 1, set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the calculation is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
VPTESTMD k1{k2}, ymm2, ymm3/m256/m32bcst (V5+VL
__mmask8 _mm256_test_epi32_mask(__m256i a, __m256i b)
__mmask8 _mm256_mask_test_epi32_mask(__mmask8 k2, __m256i a, __m256i b)
For each DWORD, calculate bitwise (1) & (2), if any bit of the result is 1, set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the calculation is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
