@Andrew, if you have GHC built with a real GCC, theres no perf issue. (though if you built GHC with clang, thereis)
I've a bindist thats from the 7.8 branch from 5 days ago that I built wiht GCC-4.8 here https://github.com/cartazio/ghc/releases/tag/carters-build-7.8-preRC1 you may need to patch the settings file to point to your own GCC version point being, no issue if you built with GCC. :) On Tue, Feb 4, 2014 at 4:31 PM, Austin Seipp <[email protected]> wrote: > TL;DR OS X suffers a performance hit when build with llvm-gcc/clang. > The binary builds are built this way.
