SUBPD
Usage: SUBPD dest,src Modifies flags: None
Performs an SIMD subtract of the two packed double-precision floating-point values in the 'src' operand from the two packed double-precision floating-point values in the 'dest' operand, and stores the packed double-precision floating-point results in the 'dest' operand.
Packed Double-Precision FP Subtract
SUBPD xmm1,xmm2/m128 ; 66 0F 5C /r [WILLAMETTE,SSE2]
SUBPD subtracts the packed double-precision FP values of the source operand from those of the destination operand, and stores the result in the destination operation.
The 'src' operand can be an XMM register or a 128-bit memory location. The 'dest' operand is an XMM register.
EXAMPLE:
subpd xmm1 xmm2
