I took a look at the bug and looks like the inrange attribute can be applied to
builtin functions too.
So now the example code
int main (void)
{
__builtin_printf ("%i\n", __builtin_isalpha (999999));
}
Now gives the following error:
foo.c: In function 'main':
foo.c:3:31: warning: argument in position 1 not in rage of 0..255 [-Winrange]
3 | __builtin_printf ("%i\n", __builtin_isalpha (999999));
