[LLVMdev] Regarding BasicBlock Cloning
The clone llvm:CloneBasicBlock copies the phi function in the replicated basic block from the original basic block. I don't want the copy of phi in relplicated block. For now I am creating .bc file with -O0 option so that it doesn't generate phi function in first place. Is this a good approach or there are some other function available for it.

CloneBasicBlock isn't going to do anything magical... I pointed towards BasicBlock::s...

...are in place and all the terminator instructions are modified so that your control-flow graph is the way you want it to be, you can run mem2reg to change your alloca variables into real SSA variables with phi-nodes in your new basic blocks. -- John T. > I don't want the copy of phi in relplicated block.

Hi, I am writing a pass for constant propagation using graph restructuring ( code duplication). I am facing following difficulties.. 1) I need to replicate the basic block but without phi function in the replicated block. How can I do this. 2) I need to insert that basic block after and before some particular basic block. Regards Tarun Agrawal -------------- next part -------------- An HTML
