Instruction
VSQRTSH xmm, xmm, xmm
Synopsis
 _mm_sqrt_sh(__m128h a, __m128h b);
Description
Compute the square root of the lower half-precision (16-bit) floating-point element in "b", store the result in the lower element of "dst", and copy the upper 7 packed elements from "a" to the upper elements of "dst".
Operation
dst.fp16[0] := SQRT(b.fp16[0])
dst[127:16] := a[127:16]
dst[MAX:128] := 0
