PFSUB
Usage: PFSUB dest,src Modifies flags: None
Performs subtraction of the source operand from the destination operand. Both operands are single-precision, floating-point operands with 24-bit significands.
Packed Single-Precision FP Subtract
PFSUB mm1,mm2/m64 ; 0F 0F /r 9A [PENT,3DNOW]
PFSUB subtracts the single-precision FP values in the source from those in the destination, and stores the result in the destination operand.
dst[0-31] := dst[0-31] - src[0-31],
dst[32-63] := dst[32-63] - src[32-63].
EXAMPLE:
pfsub mm1 mm2
