cfgexpand.c (expand_stack_alignment): Assert that stack_realign_drap and drap_rtx must match.
2008-08-01 H.J. Lu <hongjiu.lu@intel.com>
* cfgexpand.c (expand_stack_alignment): Assert that
stack_realign_drap and drap_rtx must match.
* function.c (instantiate_new_reg): If DRAP is used to realign
stack, replace virtual_incoming_args_rtx with internal arg
pointer.
