#9304: Floating point woes; Different behavior on Mac vs Linux -------------------------------------+------------------------------------ Reporter: lerkok | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: floating point Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: 9276 Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by lerkok): @carter: Ah, that's better! With "-O", I get the correct result. (i.e., the one that matches the Mac.) In fact, no other flags needed. With "-O" I get the correct behavior; regardless of -msse2/-fexcess-precision, and without "-O" I get the incorrect one. So, when compiled with optimizations it's correct, but not without? I'm not sure what to make of this. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9304#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
