Instruction
VSQRTSS xmm {z}, xmm, xmm
Synopsis
 _mm_maskz_sqrt_ss(__mmask8 k, __m128 a, __m128 b);
Description
Compute the square root of the lower single-precision (32-bit) floating-point element in "b", store the result 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 3 packed elements from "a" to the upper elements of "dst".
Operation
IF k[0]
	dst[31:0] := SQRT(b[31:0])
ELSE
	dst[31:0] := 0
FI
dst[127:32] := a[127:32]
dst[MAX:128] := 0
