Re: RFA: xscale-elf -mstrict-prototypes

I am trying to avoid the overhead of conditioning a shorter-than-int
parameter in the callee.

Yes -- but I believe that is exactly the case that will be fixed in AACPS. I might be wrong, though.

int
main (int argc, char *argv[])
{
  return addhi3 (40000, -50000);
}
This call will pass out of range values to addhi3 which is incorrect but
may happen in existing code.

We don't have to worry about that case, since, as you say, its invalid.

I believe that GCC is doing the conditioning at both the caller and callee currently. It should be necessary to do it on only one side or the other. Therefore, I think that we should eliminate that duplication, rather than add -mstrict-prototypes.
