#9307: wave4main in nofib fails -------------------------------------+------------------------------------- Reporter: jrp | Owner: Type: bug | Status: new Priority: low | Milestone: 7.10.1 Component: NoFib | Version: 7.8.3 benchmark suite | Keywords: wave4main Resolution: | Architecture: x86_64 (amd64) Operating System: MacOS X | Difficulty: Unknown Type of failure: Incorrect | Blocked By: result at runtime | Related Tickets: Test Case: wave4main | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by rwbarton): * priority: normal => low Comment: I'm pretty sure I know why this is happening. Basically this program's output is very sensitive to whether certain floating-point numbers that are very close to zero wind up being positive or negative. It might be worth tracking down exactly why the behavior differs when GHC is built with LLVM at some point though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9307#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
