[LLVMdev] problem trying to write an LLVM register-allocation pass
Hi Susan, The meaning of "addRequired(X)" is that your pass needs X to be run, and for X to be preserved by all passes that run after X and before your pass. The PHIElemination and TwoAddressInstruction passes do not preserve each other, hence there's no way for the pass manager to schedule them for you if you addRequire(...) them. The trick is that CodeGen will schedule both of these passes to be run before _any_ register allocation pass (see Passes.cpp), so you nee...

[LLVMdev] problem trying to write an LLVM register-allocation pass
I'm trying to write a MachineFunctionPass to do register allocation. I have code that worked with an old version of LLVM. It does not work with llvm-3.1. (or various other versions that I've tried). The first problem is that including this line: AU.addRequiredID(TwoAddressInstructionPassID); in method getAnalysisUsage causes a runtime error: Unable to schedule 'Eliminate PHI
