...my understanding, there is neither a register map or any sort of runtime-contract regarding the registers. Also, I need to work my way among the LLVM optimizations which move values around registers (for instance the fastcc convention which is essential for tail recursive optimization). -- Angelos Manousaridis

I am trying to write a MachineFunction pass and build it as a loadable module. I want the pass to run after prolog/epilog emmiter. So far, I have been using MachineFunctionPass, but by inserting it to lib/Codegen and hacking the LLVMTargetMachine file, and Pass.h files. I have created a directory "lib/Transforms/MyPass", and inside I have the code of the pass (which is just a
