similar to: [LLVMdev] Function Argument in LLVM

Dear All, I am working on a LLVM bitcode based project in which we do static lockset analysis. I need to get Aliasing information statically given the .bc file of the application. Is there any library in LLVM which already implements the aliasing? (does it support multi-threaded apps?) What is the best way of doing it (I want to extract aliasing information in runOnModule() function in the pass I

Thanks for your reply. Is it not possible to do with llvm-g++ -g? and furthermore, where are SDNode and DebugLoc fields stored? are they in a file which I have to parse myself? if so, is there any way that I use a library to get the file/line information for each instruction? since, I am writing a pass for opt tool that manipulates the callgraph and want to get the line number information in

Hi, I am new to LLVM, and need to find the line number and cpp source file name for each instruction in a .bc file. I suppose llvm debugger might have that feature but there is no documentation on it. Would you please give me some help how to do it?

I would like to instrument certain function calls with a function call of my own that takes some of the same arguments. For example, I would like to instrument calls to free with some function foo, so the C code would look like: foo(myarg1, myarg2, ptr); free(ptr); The problem occurs when I grab the arg from the free function and try to pass it to foo... if (isCallToFree(&I)) { Value*

Hi, I'm trying to add function calls in the LLVM IR using the IRBuilder class. I've read both tutorials about functions but I still get assertion errors. I allocate memory for all function arguments and pass them as explained in the tutorial. My code is (this function is supposed to add a call to f in bb at pos): void addCallSite(Function *f, BasicBlock *bb, BasicBlock::iterator pos)

Hi all, Sorry for the inconvenient about the previous post. The files were not attached. So I put them here again. I am a newbie in LLVM and I am trying to replace the function like: old function || new function ============================== ========= int haha(int a) { int haha(int a, char* ID) { ===> }

Dear All, I am new to LLVM and try to write a Module pass. In the same .cpp file I am defining a class. The problem is that whenever I instantiate an object from the class I get the following error while running the pass: opt: symbol lookup error: ../llvm/Debug/lib/MyPass.so: undefined symbol: _ZN10Thread_MyPassC1Ev The pass is compiled correctly but does not run. Could you someone please let

Thanks for your reply. Is it not possible to do with llvm-g++ -g? Yes and furthermore, where are SDNode and DebugLoc fields stored? They are probably classes in the Clang API are they in a file which I have to parse myself? if so, is there any way that I use a library to get the file/line information for each instruction? Yes Clang API :- http://clang.llvm.org/doxygen/classes.html

I'm now writing a pass and I wanna ask a question about how to duplicate the function and add duplicated arguments in llvm, for example: func(int a, char *b) -> func(int a, char *b, int a1, char *b1) I'm now stuck at using "getOrInsertFunction" and how to handle "getArgumentList", please share your opinion, thanks a lot! James

Dear All, To add to this, what you want to do is find the appropriate debug stop point intrinsic and then use it to look up the information for that instruction. Here is some sample code from SAFECode that finds the debug information associated with a CallInst (LLVM call instruction) held in the variable CI. It uses the findStopPoint() function in llvm/Analyis/DebugInfo.h: // // Get the

Hi, I am Saman, a UIUC PhD student working with LLVM. Would you please let me know how I can extract CG and CFG for a given application?
