Re: GHC vs. GCC on raw vector addition

I'm running GHC and GCC head-to-head on the task of adding a bunch of long IOUArray-Vectors really fast. My machine is a Linux-ppc PowerBook and gets a runtime for the GHC-compiled binary that's about 10x as long as for GCC.

Is it possible that gcc is making use of the ppc AltiVec instructions, and ghc is not? Regards, Malcolm
