I believe this optimization is valid for all well-formed values and

It probably needs to key off -msoft-float also. This is unlikely to be a win on any target with FP hardware, as the cost of moving values from the FP regs to the integer regs would be much higher than the cost of an FP compare. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
