A.5.279 RSQRTPS: Packed Single-Precision FP Square Root Reciprocal
RSQRTPS xmm1,xmm2/m128 ; 0F 52 /r [KATMAI,SSE]
RSQRTPS computes the approximate reciprocals of the square roots of
the packed single-precision floating-point values in the source and
stores the results in xmm1. The maximum error for this approximation is:
|Error| <= 1.5 x 2^-12
