How much faster does optimized code run for different optimizations?
I believe Daniel Bidwell ( http://www2.andrews.edu/~bidwell/ ) worked
on that question in his PhD dissertation, as well as how much do the
optimizations cost.
As I recall, he found that "folding," performing constant arithmetic at
compile time, not only makes the compiled code run faster, but also the
compiler.
