Register:

MMX 64 bit

Return Type:

__m64

Param Types:

__m64 a, __m64 b

Param ETypes:

UI64 a, UI64 b

__m64 _m_pcmpeqb(__m64 a, __m64 b);

Intel Description

Compare packed 8-bit integers in “a” and “b” for equality, and store the results in “dst”.

Deprecated since version X87: MMX technology intrinsics can cause issues on modern processors and should generally be avoided. Use SSE2, AVX, or later instruction sets instead, especially when targeting modern processors.
