similar to: [LLVMdev] Regarding a pass in 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

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

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 -my-ana t.bc I found out that some condition is failing in a file.

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...

I'm surprised they aren't eliminated for you. Ciao, Duncan. PS:

Hi, I am trying to add alias analysis in llvm. I created a file ProfileAlias.cpp in llvm source at the place where Andersens.cpp is there. ProfileAlias.cpp does nothing at present just empty definitions of required functions. When I build llvm I get the following error: /home/ambika/llvm1/llvm-obj/Release/lib/libLLVMipa.a(ProfileAlias.o): In function `llvm::createProfileAliasPass()':

Andi

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():

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.

Hi, Yeah I found that it is running LLVM's functions. The functions that are running are: main llvm.dbg.func.start llvm.dbg.stoppoint scanf llvm.dbg.region.end But I dont want all the functions to be called as I am using Dominator Trees and whenever I the statement DominatorTree &DT = getAnalysis<DominatorTree>(F); is encountered by functions other than main, it gives error.
