#11649: LLVM code generator produces mal-formed LLVM blocks -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 8.0.1-rc2 (CodeGen) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Indeed if you compile with the native code generator you'll find that compilation succeeds as expected, but the resulting executable loops when you attempt to evaluate `some U1`. I suspect overriding `some` and `many` is the right thing to do in this particular case. That being said, apart from the `Generics` issue, there is clearly an LLVM code generator issue as well: we shouldn't be passing code to LLVM that it can't compile. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11649#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
