Hello HJ, As you probably know, we already allow spaces in lots of places. eg. mov % al , 5 ( % ebp , % ebx , 1 ) Notice that no spaces are allowed *in* a register name, or for that matter in an instruction mnemonic. eg. mov $1, % a l is illegal. So there is a philosophical question as to whether "st(1)" is really an indivisible register name token or not. You seem to say that the register name is "st" with an index, so therefore we should allow spaces, eg. "st ( 1 )". I'm inclined to say that "st(1)" is really just a name like any other register name, so spaces shouldn't be allowed (or if we do allow spaces here then why not in "% a l" - something I don't like). Where did you run into a need for spaces in fp reg names? C asm macros?
