FCOMPP Compare Real and Pop Twice Exception Flags: I D
FCOMPP
Logic: CMP ST, ST(1)
sets condition codes in the status word and then pops
twice:
C3 C2 C1 C0 Means
-- -- -- -- -----------
0 0 ? 0 ST > source
0 0 ? 1 ST < source
1 0 ? 0 ST = source
1 1 ? 1 ST not comparable to source
FCOMPP compares ST(1) to ST, sets the condition codes as shown above, and
pops the stack twice. It takes no operands.
