Re: [GHC] #7684: cgrun071 segfaults

#7684: cgrun071 segfaults ----------------------------------+---------------------------------- Reporter: tibbe | Owner: Type: bug | Status: patch Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: Runtime crash | Difficulty: Unknown Test Case: cgrun071 | Blocked By: Blocking: | Related Tickets: ----------------------------------+---------------------------------- Comment (by simonmar): Well, one bug is that in `emitPopCntCall` we don't cast the argument to the correct width. The `-dcmm-lint` should catch it, because the argument width isn't the same as the primop is expecting, but the Cmm linter doesn't check the arguments of prim calls (that's another bug). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7684#comment:42 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
