Sounds plausible (and quaint!), but I'm not sure I'm following the scenario. I'm interpreting "reverse order" as "left most argument pushed last." So, suppose putchar(int c) is a wrapper around fputc(int c, FILE *f):
int putchar(int c)
return fputc(c, stdout);
So, in pseudo-code, the resultant assembly ought to look roughly like this (assuming tail-call optimization):
POP 'c' into a register
PUSH 'c' back on stack
JUMP to fputc and let it return for us.
It seems like if arguments went in reverse order, then adding the FILE * argument at the beginning would be the optimization:
JUMP to fputc and let it return for us
I must be missing something.
