This is a hot topic in the compiler research community, but the focus there is on (a) choosing the right optimization sequences internally and transparently, rather than through combinations of options, (b) performance prediction techniques so you don't actually have to run gazillion different choices, and perhaps can even avoid the problem of choosing representative inputs, as you talked

I'm cross-posting the message below (from GCC list) because I believe it would (at some point) be very beneficial to build an evolutionary optimization pass into LLVM. The idea would be to discover the perfect set of optimizations for a given program by trying them all and analyzing the execution times of each. This would be somewhat like profile driven optimization except the profile is
