The following two commits are relevant. The first one changes the test to only run for `WAY=optc` on x86. The second deletes `WAY=optc`. So now the test is always skipped on x86. That doesn't mean the problem is solved though! * commit 05a2f49caba62723992a03676f6df6085aa514c7 {{{ Author: Simon Marlow <marlowsd(a)gmail.com> Date: Tue Nov 24 10:14:34 2009 +0000 ffi005: run only the via-C way on x86 platforms due to 80-bit vs. 64-bit precision leading to floating point differences when using the native code generator. -fvia-C uses the -ffloat-store gcc sledgehammer to avoid this. }}} * commit dc34ea9fd80f493e00062c276b2c7c898505bca2 {{{ Author: Max Bolingbroke <batterseapower(a)hotmail.com> Date: Sat Apr 2 11:25:01 2011 +0100 Remove any mention of optc/profc from all.T files }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4105#comment:12> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
