{- Gruesome swamp follows. If you're unfortunate enough to have ventured
this far into the jungle AND you give a Rat's Ass (tm) what's going
on, here's the deal. Generate code to do a floating point comparison

example, consider generating the an equality test:
- pushl %eax -- we need to mess with this

fcomp <src2 location in FPU stack> and pop pushed src1

- -- C3 C2 and C0
- fstsw %ax -- Move FPU Status Reg to %ax
- sahf -- move C3 C2 C0 from %ax to integer flag reg
+ -- Result of comparison is in FPU Status Register bits
+ -- C3 C2 and C0
+ fstsw %ax -- Move FPU Status Reg to %ax
+ sahf -- move C3 C2 C0 from %ax to integer flag reg
-- now the serious magic begins
- setpo %ah -- %ah = if comparable(neither arg was NaN) then 1 else 0
+ setpo %ah -- %ah = if comparable(neither arg was NaN) then 1 else 0
sete %al -- %al = if arg1 == arg2 then 1 else 0
andb %ah,%al -- %al &= %ah
-- so %al == 1 iff (comparable && same); else it holds 0
- decb %al -- %al == 0, ZeroFlag=1 iff (comparable && same);
+ decb %al -- %al == 0, ZeroFlag=1 iff (comparable && same);
else %al == 0xFF, ZeroFlag=0
-- the zero flag is now set as we desire.
