#7640: Crash in stg_ap_p_fast on ARM on executable output by registerised/LLVM cross compiler ----------------------------------+----------------------------------------- Reporter: StephenBlackheath | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (LLVM) | Version: 7.7 Keywords: | Os: Unknown/Multiple Architecture: arm | Failure: Runtime crash Difficulty: Unknown | Testcase: Blockedby: | Blocking: 7623 Related: | ----------------------------------+----------------------------------------- Changes (by simonmar): * difficulty: => Unknown Comment: This might be another symptom of these bugs I fixed yesterday: {{{ commit 490920583817a650e45956025fce64af2ea1bb92 Author: Simon Marlow Date: Wed Jan 30 15:42:01 2013 +0000 We should be including HaskellMachRegs.h here, not RtsMachRegs.h This was causing GenApply.hs to use the host architecture's register settings rather than the target's, with the result that some cross-compiled programs would crash. commit a217e7a27a8d48095e2e276ed07a203254bf8743 Author: Simon Marlow Date: Wed Jan 30 19:40:07 2013 +0000 include "stg/MachRegs.h" -> include "MachRegs.h" We were getting the installed compiler's MachRegs.h sometimes (in GenApply.hs, as it turns out). This probably caused some weird effects... }}} these were causing similar kinds of crashes with an RPi cross compiler. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7640#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
