Help with NASM macros?
 

Ok, I am trying to write a macro in NASM, for part of it I want to see if they gave me a fpu register (st0, st1, st2, etc..) or something else. I can use %ifidn to check exact string text, but it doesn't appear as if I can use the logical or (||) with %ifidn. So what can I do?
thanks
