#7996: building GHC HEAD with llvm-3.4(HEAD) fails -----------------------------+---------------------------------------------- Reporter: carter | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.7 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- Comment(by thoughtpolice): This is happening when the bootstrap compiler is invoked at the beginning of the build process. The problem is that GHC 7.6.3 does not have the fix from your commit the other week, so it will generate empty metadata tripping the assert. The long and short of this is that 7.6.3 will support up-to LLVM 3.2 (except it's kind of broken,) but 7.8 will be fine with 3.3+ -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7996#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
