🚀 go-pugleaf

The following source file:

void
foo (short a, short b)
{
  void do_1(), do_2();
  
  if ((a | ((int)b << 16)) & 01000)
    do_1 ();
  else
    do_2 ();
}

      

Generates the following warning (with -Wall):

foo.c:6: warning: shift count exceeds width of value shifted

Near as I can tell, this is incorrect; the value being shifted is a
thirty-two bit integer.

The following source file does not generate the warning:

void
foo (short a, short b)
{
  void do_1();
  
  do_1 (a | ((int)b << 16));
}
