Hello, Nathan

> 2. The following assertion failure in RegisterScavenging.cpp (using llc2.6):
Use top of the tree, not LLVM 2.6, not even 2.7. ARM support is pretty
much buggy and weak in 2.7

Make sure you're using the latests binutils snapshot, prev. versions
are known buggy.
2.20.1 release is not enough.

These two rules should reduce the amount of problems, I'd suppose, down to zero.
