#9391: LLVM 3.2 crash (AVX messes up GHC calling convention) -------------------------------------+------------------------------------- Reporter: scpmw | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 (LLVM) | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: MacOS X | Difficulty: Easy (less than 1 Type of failure: Runtime | hour) crash | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by thoughtpolice): * status: patch => infoneeded Comment: Comments: For the check on line 1444 for `ver == 32`, why is this last? If we only issue a warning, then it will simply match on `isAvxEnabled dflags` (line 1443) and still pass in the right arguments. Would it not be more correct to have this branch checked first and instead turn off AVX completely? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9391#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
