INSTRUCTION SET REFERENCE
MINPS—Packed Single-FP Minimum
Description
The MINPS instruction returns the minimum SP FP numbers from XMM1 and XMM2/Mem. If
the values being compared are both zeroes, source2 (xmm2/m128) would be returned. If source2
(xmm2/m128) is an sNaN, this sNaN is forwarded unchanged to the destination (i.e., a quieted
version of the sNaN is not returned).
