...ck in LLVM? I found utility to clone machineInstrs, but couldn’t find similar utility for MachineBasicBlock. So, I created a utility myself for cloning a MachineBasicBlock, but I am running into an issue when LLVM is trying to  destroy the use list for registers (RemoveRegOperandsFromUseLists--> RemoveRegOperandFromRegInfo()-->NextOp->getReg() – where nextOp seems like invalid but not NULL). Its hitting assert in one of the registers that is getting reused in the cloned block What I am trying to do is to use exact set of virtual registers in both the blocks. Will it cause any issues?   Here is the snippet of w...
