You definitely need 3.5.2 as there were GHC calling convention-related bug fixes in that version. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11236#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Thanks! I have installed LLVM 3.5.2 and it now is working fine. It will be great if GHC configure script is doing version checking of LLVM
= 3.5.2, report warning and stop using it if it is under 3.5.2 for ARM.

#11236: Illegal instruction on ARMv7 with official build and simple program (IMX53 board) -------------------------------------+------------------------------------- Reporter: varosi | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: wontfix | Keywords: ARMv7 Operating System: Linux | Architecture: arm Type of failure: Incorrect result | Test Case: at runtime | Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by rwbarton): * status: new => closed * resolution: => wontfix Comment: Agreed that there should be such a check in the GHC 7.10 line. But HEAD will require LLVM 3.7+, which I imagine contains the relevant bug fix that is in 3.5.2. And I don't know whether there will be another release of GHC 7.10. The GHC 8.0 release should be just a few months away anyways. So for that reason, even though your request is completely correct, I'm going to go ahead and close this ticket as wontfix. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11236#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
