with support of loop unrolling,
GHC calls this "inlining".
1. loop unrolling means generating several iterations of loop body, so that, say, 100 iterations of *p++=*q++ becomes 25 iterations of *p++=*q++; *p++=*q++; *p++=*q++; *p++=*q++; 2. actually, ghc can't inline tail-recursive functions at all (although i don't checked this after 6.4) there are also many more optimization tricks. i don't think that modern compiler with optimization level comparable to gcc can be delivered without many man-years of development -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
