command subpd destination, source

Subtracts the source from the destination. Used for Subtracting Packed-Double-Precision Floating-Point Values. The subpd command can only be used with xmm registers.


Performs an SIMD subtract of the two packed double-precision floating-point values in the source operand (second operand) from the two packed double-precision floating-point values in the destination operand (first operand), and stores the packed double-precision floating-point results in the destination operand. The source operand can be an XMM register or a 128-bit memory location. The destination operand is an XMM register.
