Maybe you built GHC's libraries at too low an optimization level?
Heh, that’s it. I switched to `quickest` earlier to do a bisect, and did not switch back :-) Anyways, this produces a `ja` command now: {{{ _c36F: movsd 7(%rbx),%xmm0 xorpd %xmm1,%xmm1 ucomisd %xmm1,%xmm0 ja _c36U }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10750#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
