Forgot where I got this (ie credit not mine), but:
given:
-(id)method:(id)arg2 bar:(id)arg3 baz:(id)arg4
ppc/ppc64: x86_64: i386:
arg0 (self) $r3 $rdi *(id*)($ebp + 8)
arg1 (_cmd) $r4 $rsi *(SEL*)($ebp + 12)
arg2 $r5 $rdx *(id*)($ebp + 16)
arg3 $r6 $rcx *(id*)($ebp + 20)
arg4 $r7 $r8 ?
arg5 $r8 $r9 ?
