explow.c (optimize_save_area_alloca): New function for targets where SETJMP_VIA_SAVE_AREA is true.
* explow.c (optimize_save_area_alloca): New function for targets
where SETJMP_VIA_SAVE_AREA is true.
(allocate_dynamic_stack_space): On SETJMP_VIA_SAVE_AREA targets,
compute the amount of stack space needed should we find later that
setjmp is never called by this function, stuff rtl for this inside
a REG_NOTE of the final SET of stack_pointer_rtx.
* toplev.c (rest_of_compilation): If SETJMP_VIA_SAVE_AREA and
current_function_calls_alloca, call optimize_save_area_alloca.
