I believe gdc has the full suite of gcc optimiser flags available. You don't need to just slap -O3 on and then complain about the changes it makes, you can choose with a reasonable amount of precision which optimisations you do/don't want done.
DMC++ has similar switches, but nobody uses them, and they are pretty much useless anyway, because:
1. you need to be a compiler guy to know what they mean - very few people know what "code hoisting" is
2. it's the combination of optimizations that produces results - they are not independent of each other
This is why I didn't include such switches in DMD.
