...but perhaps someone has seen this before and can answer. I am trying to add a new register allocator to my target, and would like to use the Strong Phi Elimination pass. I am doing the following in my allocator virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequiredID(MachineDominatorsID); AU.addRequiredID(StrongPHIEliminationID); // Eliminate PHI nodes AU.addRequired<LiveStacks>(); AU.addPreserved<LiveStacks>(); AU.addRequired<MachineLoopInfo>(); AU.addPreserved<MachineLoopInfo>(); MachineFunctionPass::getAnalys...
