similar to: [LLVMdev] Question regarding value being loaded in some load instruction

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

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 ambika, I am not sure about this solution as i just started working in this field. How about taking analogy of a problem which ask us to find nearest common parent of two nodes in a tree. Let me know if I can be corrected. - Anubhav intern IIT M B. Tech 4th year CSE VIT University, Vellore. On 31 May 2010 22:30, <llvmdev-request at cs.uiuc.edu> wrote: > Send LLVMdev mailing list

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, 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

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

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

Can anyone tell how to get the result name or instruction name of all instruction? For example if the instruction is "x=add y,z", here i need "x". Using getName(), i am getting some instructions result name, but llvm produces some instruction like "%0=add i32 tmp, 1", here getName() shows empty string as result name. So please help.
