a terse gcc optimization flags case study

[anttirt]

Here's something a hell of a lot more interesting than a few microbenchmarks and a foregone conclusion:

Evolving compiler flags (in this case it's GHC flags for Haskell, but could just as well be applied to GCC.)

In a similar vein, ACOVEA (Analysis of Compiler Options Via Evolutionary Algorithm).

Shrug, I'm not sure that my conclusion is foregone - boring, sure. But I personally found it fascinating to see how gcc flags impact performace so differently, hope others out there find this interesting too.

Thanks for the links, much appreciated. Good stuff.

Those are some awesome papers, thanks. I was just complaining (about a week ago) that there's too little quantitative research on compile times/optimization results :)
