PCMPGTQ - Packed CoMPare Greater Than Qword

PCMPGTQ xmm1, xmm2/m128    (S4.2
__m128i _mm_cmpgt_epi64(__m128i a, __m128i b)

For each signed QWORD, if (1) > (2) set 1, else set 0, to all bits in the corresponding QWORD of (3).
VPCMPGTQ xmm1, xmm2, xmm3/m128    (V1
__m128i _mm_cmpgt_epi64(__m128i a, __m128i b)

For each signed QWORD, if (1) > (2) set 1, else set 0, to all bits in the corresponding QWORD of (3).
VPCMPGTQ ymm1, ymm2, ymm3/m256    (V2
__m256i _mm256_cmpgt_epi64(__m256i a, __m256i b)

For each signed QWORD, if (1) > (2) set 1, else set 0, to all bits in the corresponding QWORD of (3).
VPCMPGTQ k1{k2}, xmm2, xmm3/m128/m64bcst    (V5+VL
__mmask8 _mm_cmpgt_epi64_mask(__m128i a, __m128i b)
__mmask8 _mm_mask_cmpgt_epi64_mask(__mmask8 k2, __m128i a, __m128i b)

For each signed QWORD, if (1) > (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
VPCMPGTQ k1{k2}, ymm2, ymm3/m256/m64bcst    (V5+VL
__mmask8 _mm256_cmpgt_epi64_mask(__m256i a, __m256i b)
__mmask8 _mm256_mask_cmpgt_epi64_mask(__mmask8 k2, __m256i a, __m256i b)

For each signed QWORD, if (1) > (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
VPCMPGTQ k1{k2}, zmm2, zmm3/m512/m64bcst    (V5
__mmask8 _mm512_cmpgt_epi64_mask(__m512i a, __m512i b)
__mmask8 _mm512_mask_cmpgt_epi64_mask(__mmask8 k2, __m512i a, __m512i b)

For each signed QWORD, if (1) > (2) set 1, else set 0, to the corresponding bit of (3).
If k2 bit is 0, the comparison is not done and the corresponding bit of (3) is set to zero. Upper bits of (3) are zero cleared.
