	Following the style in other parts of the compiler, the following
works for me:

    if (!goal_mem && !goal_const
!       && regno + (int) hard_regno_nregs[regno][mode] > valueno
        && regno < valueno + (int) hard_regno_nregs[valueno][mode])
      return 0;
--- 6589,6594 ----
  
    if (!goal_mem && !goal_const
!       && regno + (regno < FIRST_PSEUDO_REGISTER
! 		  ? (int) hard_regno_nregs[regno][mode] : 1) > valueno
        && regno < valueno + (int) hard_regno_nregs[valueno][mode])
      return 0;
