assembly - x64 CMPPD (Compare packed 64-bit floats) instruction -


the cmppd instruction (page 545 of intel x64 manual) says reverses operands if need use greater or greater or equal to. makes sense instruction takes 2 registers how swap operands address , register version?

you're either going have load memory operand register, use inverse comparison (greater equivalent of nle except nans) or use avx instruction (vcmppd) doesn't have limitation.
