Synopsis
_mm256_mask_cmp_epu32_mask(__mmask8 k1, __m256i a, __m256i b, _MM_CMPINT_ENUM imm8);
Description
Compare packed unsigned 32-bit integers in "a" and "b" based on the comparison operand specified by "imm8", and store the results in mask vector "k" using zeromask "k1" (elements are zeroed out when the corresponding mask bit is not set).
Operation
CASE (imm8[2:0]) OF
0: OP := _MM_CMPINT_EQ
1: OP := _MM_CMPINT_LT
2: OP := _MM_CMPINT_LE
3: OP := _MM_CMPINT_FALSE
4: OP := _MM_CMPINT_NE
5: OP := _MM_CMPINT_NLT
6: OP := _MM_CMPINT_NLE
7: OP := _MM_CMPINT_TRUE
