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():

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.

I have done that. I have defined createMyAnaPass() in Passes.h and it is defined in MyAna.cpp and used in LinkAllPasses.h But still the error : /home/ambika/llvm/llvm-obj/tools/opt/Release/opt.o: In function `global constructors keyed to opt.cpp': opt.cpp:(.text+0x1e89): undefined reference to `llvm::createMyAnaPass()' I dont understand whats the problem.

Thanks that helped me out. But now I am facing one more problem. It says : ‘llvm::ModulePass* llvm::createMyAnaPass()’ should have been declared inside ‘llvm’ but I can find no place to declare it. Where should I do it. John Criswell wrote: > ambika at cse.iitb.ac.in wrote: >> Hi, >> >> I am trying to add a pass inn LLVM, and I actually want to add it in >> source

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

We can do what scalar optimizations do. All scalar passes

Hi, I am trying to add a pass inn LLVM, and I actually want to add it in source code, not just directly into object code. For that I included the lines in my file MyAna.cpp (llvm-2.6/lib/ana/MyAna.cpp) char MyAna::ID = 0; static RegisterPass<MyAna> X("my-aa","My Analysis"); static RegisterAnalysisGroup<AliasAnalysis> Y(X); ModulePass *llvm::createMyAnaPass() {

No, this is not what I am looking for. I am looking for something like may be a debugger so that I can trace the function calls in source of llvm. llvm-db dosent work it says "debugger not implemented" when i try to use it. Can I use gdb or something like that with llvm. What I basically want is to know that when I run some Alias Analysis then from where the functions of file

llvm itself is a plain C++ program, so you can use gdb on it. gdb doesn't know how to step through compiled IR, yet.

Actually I have collected some pointer information in the form [ p -> a,c ]. Now suppose at some node I have information as [p->a,c]. Now i want to find a merge node above this node where this information is actually geting merged. So if I get a merge node above this, I can check in its predecessors if their out has only [p->a] or [p->c] and if not so then I will look for the next

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
