--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Code has changed slightly but it still seems to apply today:
/* After switches have been processed, which perhaps alter
   `fixed_regs' and `call_used_regs', convert them to HARD_REG_SETs.  */
static void
init_reg_sets_1 (void)
{
  unsigned int i, j;
  unsigned int /* machine_mode */ m;

  restore_register_info ();

#ifdef REG_ALLOC_ORDER
  for (i = 0; i < FIRST_PSEUDO_REGISTER; i++)
    inv_reg_alloc_order[reg_alloc_order[i]] = i;
#endif

  /* Let the target tweak things if necessary.  */

  targetm.conditional_register_usage ();

------- Comment #1 from joseph at codesourcery dot com  2010-03-22 12:22 -------
Subject: Re:   New: -ffixed-xxx etc processed too early

This has been around for years; when testing my iWMMXt unwind patch 
<http://gcc.gnu.org/ml/gcc-patches/2007-01/msg00049.html> I found it 
wasn't possible to test the handling of unwind info for call-clobbered 
registers using these options because of this bug.
