  Hello, I am trying to clone a machine basic block when I ran into some issues, where I am not able to make some headway. Any of yours help is highly appreciated here: My question is about Machine Basic Block Duplication:   -          Is there a utility to clone a MachineBasicBlock in LLVM? I found utility to clone machineInstrs, but couldn’t find similar utility for MachineBasicBlock. So, I

Hi Hisham, Most likely the basic blocks are the headers of two different loops. Try running viewCFG() on the function in question to see if this is the case.

Hello, I have a question regrading the analysis pass that generates loop info from an .ll code. My previous understanding was there will be just one loop header(in the loop info) for a particular loop. But, when i use isLoopHeader() member function from the loop info class I get 'true' return value for two different basic blocks. Note both basic blocks are loop conditional block(break
