Divide Reversed
Syntax: FDIVR dest,src
Divides the source by the destination and returns the quotient in the
destination. If two register operands are specified, one must be ST. If
a memory operand is specified, the quotient 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 divided by ST(1) and the
stack is popped, returning the result in ST. For FDIVRP, the source must
be ST; the quotient is returned in the destination register and ST is
popped.
