After you clone the basic block, you can probably replace the phi instruction with another value of your choice. If you're adding variables, you'll probably want to create them as allocas and use loads and stores to

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.

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

Hi I have clone a basic block using CloneBasicBlock function but it does not clone the predecessor with it. I am not able to figure out, how to set the predecessor of the cloned basic block.

In order to change the CFG, you have to

Hi, I'm trying to implement superblock analysis as an LLVM pass. In my code, a basic block is sometimes cloned and inserted into a neighboring position in the cfg, with the same successors as the original basic block. The frequently executed edge will have one predecessor, and all other predecessor edges go to the cloned block. If there are phi nodes in the successors, they are

Hello everybody. I'm quite new to LLVM and I'm encontering problems with cloning basic blocks. My two basic blocks are in the same function and it doesn't really matter how the cloned one behave for the moment. Of course, to do so, I used the cloning.h 's method "CloneBasicBlock" but I have the "Instruction does not dominate all uses!" error. I know what it

Please reply-all so that the thread is kept on llvmdev. The LLVM Programmer's Manual has examples of how to iterate over many common structures, such as instructions in a basic block[1]. Other than that, you can check the source code or doxygen[2]. Basically, you loop over the instructions as detailed in the programmer's manual[1], and loop over the operands using User's

Hi, I had asked earlier from my another ID about duplicating a basic block, but that server is down for moment. I was given suggestion to use CloneBasicBlock, but when I used it I get an error : While deleting: i32* %a Use still stuck around after Def is destroyed: store i32* %a, i32** %p, align 4 opt: /home/ambika/llvm_3/llvm-2.6/lib/VMCore/Value.cpp:81: virtual llvm::Value::~Value():

It seems the CloneBasicBlock function defined in Transforms/Utils/Cloning.h doesn't change the parent BasicBlock of the contained instructions when it has cloned them -- Is this a bug or a feature? m.
