Sib calling can happen on some targets (like the PPC) when the types are always 
sign_extended when they are returned like from short to int.
short t();
int f()
{
 return t();
}

This bug is independent of 14472. this case involves changing 
return machine modes, which is something we never had, and 
which is hard to do on trees.  14472 is about returns in the 
same machine mode, and that's a regression. which is fixed now.
