[Haskell-cafe] optimising for vector units

Hi, Does anybody know if any of the Haskell compilers are able to optimise for vector units (like MMX, SSE(2), 3D_Now! and AltiVec)? My investigations have revealed that c requires special programming constructs to make the most of these processor capabilites (i.e. the compiler is not able to work it out for itself). Is there any work on getting haskell compilers to work this kind of thing out? Cheers, Matt
