Hi all,
I forgot I once raised this on the GHC bug tracker:
http://hackage.haskell.org/trac/ghc/ticket/7025

Hi all,
You can turn on e.g. SSE 4.1 by passing -msse4.2 to ghc. This doesn't
currently imply that we compile any C code with -msse4.2 turned on, so
if someone really want to use SSE4.2, they have to do:
ghc -msse4,2 -optc-msse4.2
Do we want to change this so it's enough to pass -msse4.2 to
