For MachineBasicBlocks, check out this doc: http://llvm.org/doxygen/classllvm_1_1MachineBasicBlock.html I believe its basically the same as basic blocks in that you can manipulate the instruction list. Otherwise, you need to write a MachineFunction Pass: http://llvm.org/docs/WritingAnLLVMPass.html#MachineFunctionPass -Tanya

Hello guys, I plan to do some pre register allocation optimizations. I already know my way around LLVM but I could use some more experience. I need a way to reorder instructions inside MachineBasicBlocks or MachineFunctions. I've been searching for it but I have not found an example in the code yet. Can someone point me where I should look for? ty, -- Emilio Wuerges LAPS - Laboratorio

So I don't think making mthi/lo clobber the
