I tried out some of the vector and uvector fusion benchmarks with the new LLVM backend and got some great results for the tight loops generated through fusion.

This is excellent news!

The LLVM backend looks very promising -- considering we've not even begun to explore the optimization pipeline at the level.

There is a complete cake at: http://llvm.org/docs/Passes.html (yes, I dabbled in LLVM for some time) Some of the analysis passes gives us a nice hook into the toolchain when you want to see what is going on at the lowest level. Some of the transformations will, perhaps, yield some speedups. -- J.
