--- Comment #37 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
The patch severely breaks on SPARC though:

int foo (char c)
{
  return (int) c;
}

eric@polaris:~/build/gcc/sparc-sun-solaris2.10> gcc/xgcc -Bgcc -S -O t.c
t.c: In function 'foo':
t.c:1:5: internal compiler error: in assign_parm_setup_reg, at function.c:3120
 int foo (char c)
