Recent as(1) doesn't think that . terminates a macro name, so getuser.l is _not_ treated as invoking getuser with .l as the first argument. arch/m68k/math-emu relies on old behaviour, so it gets a lot of undefined macros with more or less current binutils. Note that this behaviour remains in all recent versions and is unrelated to another binutils problems we used to have for a while (having (%a0)+ parsed as two arguments). This one is there to stay; it's an intentional and documented change. .irp <identifier> <words> [text] .endr expands to a copy of text per each word, with \<identifier> replaced with corresponding word. Again, what happens depends on whether gas_ident.x is treated as one or as two tokens; in the former case we'll get old_gas incremented once, in the latter - twice. The rest is obvious. Unlike .macro argument list _anything_ is explicitly allowed after .irp <identifier>; here we are on very safe ground. And yes, it does work with all gas variants I've got here (including vanilla 2.15, 2.16, 2.16.1 and 2.17, plus debian and FC binutils).
