Hi Team, I am writing an LLVM pass that compiles fine and opt instrumentation goes fine as well. But when I run the instrumented C-program then I get the following stack dump. My question is, how can I debug the problem in this scenario please? // LLVM pass compiles fine and the following OPT instrumentation goes fine for basic malloc.bc program as well. Malloc.bc runs fine without any

Hello, I'm having troubles with writing a pass. In my pass I've have created a function that has two parameters - both of type i8*. Initially I wrote this function in C, that I translated it into IR, and then by using llc -march=cpp I got it's implementation in cpp code that actually inserts IR instructions. Then, I inserted this cpp code in my pass. And in some places of a program

The NIST F77 test suite doesn't seem to be compatible with gfortran at all, so I had to work from my own sample codes, and generate test cases from them. Here's what works now, and I have a separate test case for each of these: statement functions intrinsic functions (print, cos, etc) loops, goto statments scalarized array operations function calls with *no arguments* simple common

The first buildbot failure I can readily find was Monday, 26oct2009 around 7PM PDT. The assertion is Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file /Volumes/Sandbox/Buildbot/llvm/

When for example some call is wrong error message always looks like this: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file /tmp/llvm-svn/llvm/lib/VMCore/Instructions.cpp, line 247. I believe assert() statements should better be replaced with more

Dear All, I'm getting the following error building mainline llvm-gcc 4.2 (LLVM and llvm-gcc are up to date): cc1: /home/vadve/criswell/src/llvm22/lib/VMCore/Instructions.cpp:290: void llvm::CallInst::init(llvm::Value*, llvm::Value*): Assertion `(FTy->getNumParams() == 1 || (FTy->isVarArg() && FTy->getNumParams() == 0)) && "Calling a function with bad

Hi! I have this error while building my code: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!") Actually I'm trying to load functions from .bc file and use them in the code that I'm building with IRBuilder. I found that function parameter type is %struct.reValue* and

Hi all, I am working on my Master's project in security and I am trying to iterate over the argument list of the function. Basically I need to do following things : 1. Check data type of each argument of the argument list of the function. 2. Based on its data type like character array or integer array, pointer, int, char, take different action. 3. I have added following code to check its

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)

I am finding that llvm 2.8 rc3 with dragonegg svn built against current gcc-4_5-branch doesn't appear to allow gfortran to use -ffast-math. Attempting to compile code using the dragonegg plugin under gcc 4.5.2 with that option produces the error... f951: Unknown command line argument '--enable-finite-only-fp-math'. Try: 'f951 -help' The standard gcc 4.5.2 gfortran compiler

Hi all, I am creating a function and trying to call it using the LLVM API. It seems that whenever the function type includes an opaque-typed parameter, the CallInst::Create call causes an assert: Assertion failed: ((i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType()) && "Calling a function with a bad signature!"), function init, file

I'm trying to use CallInst::Create to construct a call to a variadic function, and I'm running into the following assertion failure: /localhome/simmon12/workspace/llvm-sources/lib/VMCore/Instructions.cpp:297: void llvm::CallInst::init(llvm::Value*, llvm::Value* const*, unsigned int): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Params[i]->getType())

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!

Hi everyone, I am trying to write a pass, that finds some instructions and replaces them with my intrinsics, but I am having problem understanding, how this should be done. Let's say I have this instruction: %tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28) and i need to read the load's operands and replace it by let's say: %tmp14 = call i32
