Re: ghc sparc NCG

At the moment -fvia-C is produces somewhat faster code than -fasm on all arches. Though the difference varies between arches, I've heard that -fsam is very nearly on par with -fvia-C on x86-64.

On x86, -fasm is slower for floating point, but probably about the same for integer code. On x86_64, -fasm is about the same as -fvia-C. On powerpc, I believe -fasm is better than -fvia-C. Partly this is because we don't give gcc much room to maneuver. See this wiki page for our long term plan: http://hackage.haskell.org/trac/ghc/wiki/BackEndNotes Basically we want to beef up the NCG and deprecate -fvia-C. Cheers, Simon
