The point of my ticket is that Apple does not supply them so the doc is wrong in that regards. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8792#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The doc refers to OS X and is wrong wrt LLVM, correct? When I said llvm 3.4 is the preferred version I meant for MAC OS X and I believe for Windows and Linux which is what this section of the document refers to. I should have written I believe llvm 3.4 is the preferred version for Mac OS X ... Additionally for Mac OS X it should mention that Clang is available from Apple not supplied by default, correct? However you have a good point about llvm 3.0 being the preferred version for 3.0. Thanks for bringing that up, definitely needs to be documented. Is the problem with 3.4 on the llvm side or the Haskell side? Are there other OS that require an earlier version of llvm? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8792#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

ok, so the issue is that the direction for OS X are wrong.

It was hard to parse you ticket :) Yes, sorry about that.
