MAXPD
Usage: MAXPD dest,src Modifies flags: None
Performs an SIMD compare of the packed double-precision floating-point values in the 'dest' and the 'src' and returns the maximum value for each pair of values to the 'dest' operand.
Return Packed Double-Precision FP Maximum
MAXPD xmm1,xmm2/m128 ; 66 0F 5F /r [WILLAMETTE,SSE2]
MAXPD performs a SIMD compare of the packed double-precision FP numbers from xmm1 and xmm2/mem, and stores the maximum values of each pair of values in xmm1. 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 QNaN version of the SNaN is not returned).
The source operand can be an XMM register or a 128-bit memory location. The destination operand is an XMM register.
