#10383: AArch64: get GHC Calling convention working ----------------------------------------+------------------------------- Reporter: erikd | Owner: erikd Type: feature request | Status: new Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: aarch64 Type of failure: Building GHC failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): ----------------------------------------+------------------------------- Comment (by erikd): Oh wow, that is embarrassing! Rechecked the `mk/build.mk` file and found that `BuildFlavour` was not set. Not sure what the hell it was building. Anyway, setting `BuildFlavour=quick-llvm` I then get: {{{ "inplace/bin/ghc-stage1" -static -O0 -H64m -fllvm -Iincludes -Iincludes/dist -Iincludes/dist-derivedconstants/header -Iincludes/dist- ghcconstants/header -Irts -Irts/dist/build -DCOMPILING_RTS -this-package-key rts -dcmm-lint -i -irts -irts/dist/build -irts/dist/build/autogen -Irts/dist/build -Irts/dist/build/autogen -O2 -c rts/PrimOps.cmm -o rts/dist/build/PrimOps.o 0 libLLVM-3.6.so.1 0x0000007f787be130 llvm::sys::PrintStackTrace(_IO_FILE*) + 48 Stack dump: 0.

(Exit code: -11) rts/ghc.mk:246: recipe for target 'rts/dist/build/PrimOps.o' failed }}} Seeing LLVM 3.6 break like this, I hacked `configure.ac` to accept `llvm-3.7` and then got: {{{ You are using a new version of LLVM that hasn't been tested yet! We will try though... /usr/bin/opt-3.7: /tmp/ghc24454_0/ghc_3.ll:22:21: error: expected comma after load's type %lnI = load i64** %Sp_Var ^ `opt-3' failed in phase `LLVM Optimiser'. (Exit code: 1) }}} It seems the LLVM IR has changed between llvm-3.6 and llvm-3.7 (again). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10383#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
