A.5.155 MINSS: Return Scalar Single-Precision FP Minimum
MINSS xmm1,xmm2/m32 ; F3 0F 5D /r [KATMAI,SSE]
MINSS compares the low-order single-precision FP numbers from xmm1 and
xmm2/mem, and stores the minimum value in xmm1. If the values being
compared are both zeroes, source2 (xmm2/m32) would be returned. If
source2 (xmm2/m32) is an SNaN, this SNaN is forwarded unchanged to the
destination (i.e., a QNaN version of the SNaN is not returned). The high
three doublewords of the destination are left unchanged.
