FCP.S – Floating Point Compare
Description
Performs a compare between the two floating point operands specified. The operation is imple-
mented by doing a floating-point subtraction without writeback of the difference. The operation
sets the status flags according to the result of the subtraction, but does not affect the operand
registers. See
mnemonics corresponding to different compare results.
