-fprofile-generate and -fprofile-use

[girish vaitheeswaran]

Sorry I still did not follow. This is what I
understood. During Feedback optimization apart from
the -fprofile-generate, one needs to turn on
-fmove-loop-invariants. However this option is not
recognized by the gcc 3.4.4 or 3.4.3 compilers. What
am I missing?
