similar to: [LLVMdev] Debugging my pass with llvm

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 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() {

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.

We can do what scalar optimizations do. All scalar passes

I have not made a separate pass. I have done it in single pass ie added ProfileLoaderPass , got information in PI and now I am planning to perform the analysis here itself. I was trying to print information using ProfileInfoPrinter pass but was unable to do it. namespace { class MyAna : public ModulePass { ProfileInfo *PI; public: static char ID; // Class identification, replacement

Hi, How can I use profile information into my pass for performing some analysis. I tried something like: PassManager PassMgr = PassManager(); cl::opt<std::string> ProfileDataFile(cl::Positional, cl::desc("<llvmprof.out file>"), cl::Optional, cl::init("llvmprof.out")); PassMgr.add(createProfileLoaderPass(ProfileDataFile));

Ah BTW...

Try doing a clean build, then doing 'make ENABLE_PIC=1' -Chris On Apr 11, 2010, at 9:13 AM, ambika wrote: > > > From: ambika <ambika at cse.iitb.ac.in> > Date: April 8, 2010 9:10:25 AM PDT > To: llvmdev at cs.uiuc.edu > Subject: [LLVMdev] Can someone help me with error while i make my own pass > > > Hi, > > I have added LoaderInterface pass in

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.

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

Actually I am interested only if the information merges at join node, otherwise not... So just getting a node with more than one predecessor might help. But can I figure out if there is a function call in between, in any of these nodes? Thanks a lot for helping out...

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

Hi, I want to duplicate a set of basic blocks and finally modify the structure of CFG. But if I just duplicate a block then name of all the temporaries will be same as in original block. So is there a way to rename all the temporaries in a basic block or I will have to do it instruction by instruction? Thanks and Regards, Ambika

Hi, Suppose I have llvm Instruction as : %9 = load i32* %b, align 4 and I want to extract the name of temporary value used here ie 9. Can any body tell that how can I do that? thanks and regards, Ambika

But this is already present in my pass. And I am not able to understand the cause for the error: opt: /home/ambika/llvm_3/llvm-2.6/include/llvm/PassAnalysisSupport.h:203: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::DominatorTree]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not "
