Hi,
Apologies if this isn't the best place. I've been looking for some information (understandable by the average user) about the real-world benefits of the polly optimiser, but have found only either very broad and vague claims or specialist research papers.
What I'd like to get an idea of is what benefits Polly brings, under what conditions, for what cost and how (= any special compiler options needed?).
Also, given I'm installing clang via MacPorts: does clang pick up Polly's presence automatically after I add the libpolly binary (i.e. port:llvm with the +polly install variant) or do I need to rebuild clang too?
Thanks,
René
