Syntax: FADD dest,src
Adds the source to the destination and returns the sum in the
destination. If two register operands are specified, one must be ST. If
a memory operand is specified, the sum replaces the value in ST. Memory
operands can be 32- or 64- bit real numbers or 16- or 32-bit integers.
If no operand is specified, ST is added to ST(1) and the stack is
popped, returning the sum in ST. For FADDP, the source must be ST; the
sum is returned in the destination and ST is popped.
