#10394: LLVM mangler doesn't mangle AVX instructions -------------------------------------+------------------------------------- Reporter: dobenour | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 (LLVM) | Operating System: Unknown/Multiple Keywords: | Type of failure: Runtime crash Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- The LLVM mangler does not currently transform AVX instructions on x86-64 platforms, due to a missing #include. Also, it is significantly more complicated than necessary, due to the file into sections (not needed anymore), and is sensitive to the details of the whitespace in the assembly. I have attached a modified mangler that I believe to be simpler and more robust. I have not tested it, though, as I do not have a recent enough version of LLVM on my machine. I am marking this as `Runtime crash' because that is what would happen if the unchanged AVX instructions made their way into the executable. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10394 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
