fcom{ls}
Compare stack element 0 with stack element 7. Condition codes contain the result: No compare=111, st 0 greater than st 7=000, st 0 less than st 7=001, equal compare=100.
fcom %st(7)
fcomp{ls}
Compare stack element 0 with stack element 7. Condition codes contain the result: No compare=111, st 0 greater than st 7=000, st 0 less than st 7=001, equal compare=100, then pop the stack.
fcomp %st(7)
fcompp
Compare stack element 0 with stack element 1. Condition codes contain the result: No compare=111, st 0 greater than st 7=000, st 0 less than st 7=001, equal compare=100, then pop the stack twice.
fcompp
ficom{l}
Integer compare stack element 0 with the contents of register ECX (with an offset of 2). Condition codes contain the result: No compare=111, st 0 greater than st 7=000, st 0 less than st 7=001, equal compare=100,
ficom 2(%ecx)
ficomp{l}
Integer compare stack element 0 with the contents of register ECX (with an offset of 2). Condition codes contain the result: No compare=111, st 0 greater than st 7=000, st 0 less than st 7=001, equal compare=100, then pop the stack.
ficomp 2(%ecx)
ftst
Compare stack element 0 with the value 0.0. Condition codes contain the result: No compare=111, st 0 greater than st 7=000, st 0 less than st 7=001, equal compare=100,
