I think this will pessimize Ada, which defaults to -fnon-call-exceptions but where we do *not* want to preserve trapping instructions just because they may trap (i.e. -fdelete-dead-exceptions is enabled by default). And, as noticed by Richard, EH is orthogonal to side effects and pure/const. -- Eric Botcazou
