I agree. It sounds useful. It's a bit confusing in that I don't know whether it means 'compile very fast' or 'make my code run very fast'. I've seen it mean the latter in most places, so I guess that's fine. Allowing backends to alter the meaning of -Ofast with target-specific switches (and even -f switches) is a good idea too. The documentation should be clear in that -Ofast WILL produce surprising results in non-standard code and it will also enable transformations that do not follow the standard. Diego.
