#8974: 64 bit windows executable built with ghc-7.9.20140405+LLVM segfaults ------------------------------------+---------------------------------- Reporter: awson | Owner: Type: bug | Status: new Priority: high | Milestone: 7.8.3 Component: Compiler (LLVM) | Version: 7.9 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ------------------------------------+---------------------------------- Comment (by awson): I think that things are pretty much explained in [http://git.haskell.org/ghc.git/blob/HEAD:/compiler/nativeGen/X86/Ppr.hs#l462 native codegen code]. But AFAIUI, when the relevant LLVM code was written, non-Windows binutils were already improved and that was not taken into account (Windows binutils are not fixable anyway in general). Then it looks `pprInfoTable` [http://git.haskell.org/ghc.git/blob/HEAD:/compiler/llvmGen/LlvmCodeGen/Ppr.h... code] is the point we could try to rewrite things at. Unfortunately, at this point we are forced to "reverse engineer" what was [http://git.haskell.org/ghc.git/blob/HEAD:/compiler/llvmGen/LlvmCodeGen/Data.... done before, and it is tempting to intervene here], but it seems we can't intervene at this early stage because this can break things in contexts other than `pprInfoTable`'s one. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8974#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
