I did not - I built the regular gcc-42 fortran as we did for SL (it's available from the usual place). Anecdotal evidence from the Web suggests that the LLVM Fortran produces slower code than the gcc Fortran. However, if you build LLVM Fortran, let me know how it goes and if it's not too painful I will try to compare both of them.

Thanks,
