Still too much work for the combiner in my opinion. :-) Can't we arrange for the REG_NORETURN and REG_ARGS_SIZE notes to be originally placed so that the combiner first puts back the former and second the latter? And why can't the latter note be put back by fixup_args_size_notes directly? -- Eric Botcazou
