Let me add that I've also noticed that the following flags (also
mentioned as part of -fast in the doc) are not recognized:
-frelax-aliasing
-fgcse-mem-alias
-fload-after-store
-fgcse-loop-depth
-funit-at-a-time
-fcallgraph-inlining
-fdisable-typechecking-for-spec
-floop-to-memset
I have not been able to get my unix app to run properly using the
-fast (or -fastf) flag. For troubleshooting, I've individually
included all of the other flags that are listed in the doc as part of
-fast without a problem, so I suspect one of these unrecognized flags
could be the cause. But since they are not recognized, I can't
isolate which might be the problem.
BTW, I have tried using both -mcpu=7450 and -mcpu=G4 with the -fast
flag (dual 800 MHz Mac). Which should be used with -fast for this Mac
(which has 7450 G4's). Is there an advantage for -mcpu=7450 vs
-mcpu=G4?

In looking at the flags included in -fast
(/Developer/Documentation/ReleaseNotes/DeveloperTools/GCC3.html), I see
reference to -floop-to-memset. Unfortunately, if I put this flag in the
"Other C++ Flags" setting, the compiler doesn't recognize the flag and
chokes. Should Xcode recognize this flag?
Thanks.
