[Bug testsuite/21062] New: Incorrect declaration of printf() in alias2.C

[oyvind dot harboe at zylin dot com]

See attached patch.

My GCC superpowers aren't quite up to analyzing this, but I suppose this would 
cause problems for e.g. the i2pk target as it would receive size=0 in its 
arguments in the function below.

If this can't be sorted out by trivial inspection, please let me know and I'll 
run some tests.

/* Returns the number of bytes of arguments automatically
   popped when returning from a subroutine call.
   FUNDECL is the declaration node of the function (as a tree),
   FUNTYPE is the data type of the function (as a tree),
   or for a library call it is an identifier node for the subroutine name.
   SIZE is the number of bytes of arguments passed on the stack.  */

int
ip2k_return_pops_args (tree fundecl ATTRIBUTE_UNUSED, tree funtype, int size)
{
  if (TREE_CODE (funtype) == IDENTIFIER_NODE)
    return size;

  if (TYPE_ARG_TYPES (funtype) == NULL_TREE
      || (TREE_VALUE (tree_last (TYPE_ARG_TYPES (funtype))) == void_type_node))
    return size;

  return 0;
}
