There has been a lot of work on improving code quality in gcc, but
most of it recently has gone into gcc 4.0, not gcc 3.3. If people
find cases where the code quality is worse in gcc than in
CodeWarrior, please file bugs with the compiler folks. They want to
know about this sort of thing. But don't file bugs against the 3.3
compiler, that is really on maintenance. Check to make sure the
problem still exists in gcc 4.0 before filing a bug.

Does CodeWarrior generate that much better/faster code
or are there settings in XCode I have missed?
In one project I converted, it turned out that for some reason
XCode set a flag to disable inlining which cost a lot of
performance. Yet, my overall impression is still that the code that
CodeWarrior 8 generates runs faster and is "cleaner" (=less
pipeline stalls in Shark) than the same code compiled in gcc3/
XCode1.5.
