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() { return new MyAna(); } I also included createMyAnaPass() in Passes.h...

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 code, not jus...

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 un...

We can do what scalar optimizations do. All scalar passes are declared in include/llvm/Transforms/Scalar.h and include/llvm-c/Transforms/Scalar.h, defined in lib/Transfo...

Hi, I have a pass named MyAna in directory /llvm-obj/lib/myana When i do make it compiles succesfully but when I try to load it I get a segmentation fault, ie when I run opt -load ../llvm-obj/Release/lib/MyAna.so -my-ana t.bc I get segmentation fault. I used bugpoint as : bugpoint opt -load ../llvm-obj/Release/lib/MyAna.so...

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 for typeinfo MyAna() : ModulePass(&ID) {} virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll(); AU.addRequired<ProfileInfo>(); }...

Ah BTW...

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));

...following: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesCFG(); AU.addRequired<DominatorTree>(); AU.addRequired<LoopInfo>(); AU.addRequiredID(LoopSimplifyID); AU.addRequired<AliasAnalysis>(); AU.addRequired<MyAnalysis>(); // Add this AU.addPreserved<AliasAnalysis>(); AU.addPreserved("scalar-evolution"); AU.addPreservedID(LoopSimplifyID); } char LICM::ID = 0; INITIALIZE_PASS_BEGIN(LICM, "licm", "Loop Invariant Code Motion&quot...
