I'd like to know your experiences with compiler loop optimizations.
What loop optimizations (in your opinion) can be applied to a large
number of programs and yield a (significant) improvement of the
I've tested the compiler optimization "loop unswitching" (also
introduced in gcc 3.4) but going through a large number of different
benchmarks I could find very few examples where the optimization could
be applied. Do you share my experience?
