... the post is from 2008. No LLVM goodness. So I thought GHC 6.12.1 (not the latest and greatest HEAD) would be enough.
I compiled the two programs myself out of curiosity and got the following times. Linux, 64bit, Ubuntu 10.10: 1e8 clang: 0.180s gcc: 0.179s ghc 6.12.1 (viac): 0.187s ghc 6.12.1 (fasm): 0.218s ghc HEAD (viac): 0.186s ghc HEAD (fasm): 0.179s ghc HEAD (llvm): 0.174s 1e9 clang: 1.657s gcc: 1.647s ghc 6.12.1 (viac): 1.653s ghc 6.12.1 (fasm): 1.975s ghc HEAD (viac): 1.648s ghc HEAD (fasm): 1.658s ghc HEAD (llvm): 1.646s So basically all have the same time except ghc 6.12.1 where fasm is a little slow. On windows xp 32bit I get quite different results which I trust less as the times are jumping around much more then they were on linux: 1e8 gcc: 0.365s ghc 6.12.1 (viac): 5.287s ghc 6.12.1 (fasm): 1.332s ghc HEAD (viac): 5.292s ghc HEAD (fasm): 0.875s ghc HEAD (llvm): 0.359s Not sure why the results on windows are so different. If anyone else wants to run the two programs on Windows and check that would be great. Cheers, David
