This is excellent news!

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.
