5. The same is for -O2. But this does not gain more performance. -O2 -fvia-C also does not gain more performance, but leads to 7 times longer compilation.
Just to be sure: are you saying that with -O2 the compile time is ok, but when you add -fvia-C it takes 7 times longer? If so, it's probably not a bug (we don't have any control over the speed of gcc). Here's the bug report: http://hackage.haskell.org/trac/ghc/ticket/2609 Sergey, could you clarify please? Cheers, Simon
