Packed Compare for Equal Intrinsic
The prototype for this Intel® Streaming SIMD Extensions (Intel® SSE4) intrinsic is in the smmintrin.h file.
To use this intrinsic, include the immintrin.h file as follows:
#include <immintrin.h>
_mm_cmpeq_epi64
__m128i _mm_cmpeq_epi64(__m128i a, __m128i b);
Performs a packed integer 64-bit comparison for equality. The intrinsic fills the corresponding parts of the result with zeroes or ones based on equality.
