#11758: Drop x86_64 binutils <2.17 hack -------------------------------------+------------------------------------- Reporter: bgamari | Owner: avd Type: task | Status: closed Priority: normal | Milestone: 8.2.1 Component: Compiler (NCG) | Version: 8.0.1-rc2 Resolution: fixed | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: 12433 | Differential Rev(s): Phab:D2426 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): This patch made the ghc-stage2 compiler seg-fault, on 64-bit Windos. It seg-faults when doing anything -- compiling `HelloWorld.hs` or even `ghc --version`. It took me a full day of bisection to find this. Very painful. It would be so great if we had continuous-integration on Windows going. I hate playing the role of Windows test engine. Anyway, here's the revert patch. Would someone like to work out what is going on, and re-apply when fixed? {{{ commit b2c5e4ce5c44a7be7c2b81c2600cae40c5b225ad Author: Simon Peyton Jones Date: Thu Aug 18 18:16:01 2016 +0100 Revert "codeGen: Remove binutils<2.17 hack, fixes T11758" This reverts commit e3e2e49a8f6952e1c8a19321c729c17b294d8c92. I'm reverting because it makes ghc-stage2 seg-fault on 64-bit Windows machines. Even ghc-stage2 --version seg-faults. compiler/nativeGen/X86/CodeGen.hs | 15 ++++++++++++++- compiler/nativeGen/X86/Ppr.hs | 23 +++++++++++++++++++++-- includes/rts/storage/InfoTables.h | 11 +++++++++++ 3 files changed, 46 insertions(+), 3 deletions(-) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11758#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
