#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 edmund): That error from opt-3.7 looks like a syntax error in the IR. If there had been a fundamental change in the IR's syntax then it would probably be mentioned in http://llvm.org/releases/3.7.0/docs/ReleaseNotes.html, but I don't see it mentioned there. Also, it says in https://www.reddit.com/r/haskell/comments/3nf3q1/improved_llvm_backend/: "There are tests in LLVM upstream for our needed features (including the new ones in LLVM 3.6+), so hopefully the scope for regressions is lower (indeed, crude hacks simply increase the cost of supporting it.) In fact, LLVM 3.7.0 worked perfectly on release, and we did some prerelease testing too." So I wouldn't be so sure that the problem you're seeing there is caused by the IR changing. Can you try using GHC with llvm-3.7 on x86_64? In general, an LLVM load instruction does contain at least one comma, I think (http://llvm.org/docs/LangRef.html#id201), so the line you quoted looks suspicious. Can you get GHC to generate some more IR and see what the other loads look like? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10383#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
