#7602: Threaded RTS performing badly on recent OS X (10.8?) -------------------------------+-------------------------------------------- Reporter: simonmar | Owner: thoughtpolice Type: bug | Status: new Priority: normal | Milestone: _|_ Component: Runtime System | Version: 7.7 Keywords: | Os: MacOS X Architecture: x86_64 (amd64) | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: 7678 | Blocking: Related: | -------------------------------+-------------------------------------------- Comment(by thoughtpolice): Sigh. I haven't seen XCode 5. The fact they EOL'd gcc finally isn't totally surprising. The summary is that I have a patch for this and it should help the performance loss quite a bit, but the blocker here is #7678 - clang's preprocessor doesn't like the way we use RULES, among other things. This is work-around-able, but probably not in a very nice way unfortunately. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7602#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
