Register:

XMM 128 bit

Return Type:

void

Param Types:

__m128i a, __m128i b, __mmask8* k1, __mmask8* k2

Param ETypes:

UI32 a, UI32 b, MASK k1, MASK k2

                          __mmask8* k1, __mmask8* k2)

Intel Description

Compute intersection of packed 32-bit integer vectors “a” and “b”, and store indication of match in the corresponding bit of two mask registers specified by “k1” and “k2”. A match in corresponding elements of “a” and “b” is indicated by a set bit in the corresponding bit of the mask registers.

Intel Description

Compute intersection of packed 64-bit integer vectors “a” and “b”, and store indication of match in the corresponding bit of two mask registers specified by “k1” and “k2”. A match in corresponding elements of “a” and “b” is indicated by a set bit in the corresponding bit of the mask registers.
