Instruction
VMINSD xmm {z}, xmm, xmm
Synopsis
_mm_maskz_min_sd(__mmask8 k, __m128d a, __m128d b);
Description
Compare the lower double-precision (64-bit) floating-point elements in "a" and "b", store the minimum value in the lower element of "dst" using zeromask "k" (the element is zeroed out when mask bit 0 is not set), and copy the upper element from "a" to the upper element of "dst".
Operation
IF k[0]
dst[63:0] := MIN(a[63:0], b[63:0])
ELSE
dst[63:0] := 0
FI
dst[127:64] := a[127:64]
dst[MAX:128] := 0
