What happens if an instruction hasn't been recognized upon reaching these parts of haifa-sched.c? Will it be only mis-scheduled, i.e. will this only result in inferior, but still correct code? If so, the assertion shouldn't be enabled in release mode but only if ENABLE_CHECKING is defined. -- Eric Botcazou
