I am interested in working on a little architecture project that involves modifying an ISA in some non-trivial ways and seeing what impact it has on instruction frequencies (and other such metrics). Clearly I'll need to hack on a compiler backend, and I thought that LLVM might be a good choice since among mature compiler infrastructures it's fairly young and presumably
