If you need to do this, I'd suggest adding a new virtual method
"insertRegisterXor" or something, which works like copyRegToReg. It
should be very straight-forward to implement for all targets. I would
suggest starting out by implementing it on whatever target you are on, and
make it abort on all others. When it comes time to make it work on other
targets, the various...

[LLVMdev] Register allocation in LLVM
Hello, all,
I want to implement the register allocation algorithm described in the
paper "Register Allocation via Coloring of Chordal Graphs, APLAS'05" in
LLVM. This is a graph coloring algorithm that can find an optimal coloring
of the interference graph in most of the cases. I've downloaded LLVM last
week, and started studying the code. Basically, I have to implement:
