__m64 _mm_cvtsi32_si64(int a);

Intel Description

Copy 32-bit integer “a” to the lower elements of “dst”, and zero the upper element of “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.

Intel Implementation Psudeo-Code

dst[31:0] := a[31:0]
dst[63:32] := 0
