Comment(by michalt): I've built GHC with the new patch on x86_64 and it doesn't introduce any failures in the testsuite. :) As for the negative zero I have absolutely no idea whether it's really important. Though functions having different results with and without optimisations make me feel uneasy. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/2271#comment:32> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
