Hi Sanjoy, the first and last patches look good (except that you didn't add any tests for the auto-upgrade functionality).

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

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

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/

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())

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

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

Hi, I tried passing the array directly using and changing the getorInsertFunction accordingly but this didn't work. It fails with Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. hookFunc = M.getOrInsertFunction("hook", Type::getVoidTy(M.getContext()),

Somewhere in f1 , I set

Hi Albert, I'm having a similar problem and I found I can't declare the function and use it, most likely

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

CreateAlloca(Type) returns an object of type Type*, the memory that can hold an object of type Type. You probably don't want to be creating allocas just before calling the function since 1) if that call winds up in a loop they'll grow your stack frame without bound, and 2) the memory they point to is initially uninitialized. Where did the tutorial tell you to do that? In general, when I

Hello, Could I get some debug info at the byte code level? I am writing a passer and if will be nice if I can know which line in the source an instruction (or value) corresponds to. I found a document online: http://llvm.org/docs/SourceLevelDebugging.html, but I can't find an example of doing it at the byte code level. Cheers, Zheng

Hello, My code: (CallInst *CI, IRBuilder<> &B) SmallVector<Value *, 8> args; Value *v = B.CreateGlobalString("hi", "str"); args.push_back(v); SmallVector<Type*, 8> params; params.push_back(v->getType()); Module *M = B.GetInsertBlock()->getParent()->getParent(); FunctionType *printfType =

Hi Andrii-- They're not equivalent as far as LLVM is concerned - the parameter type is { { i32 }. { i64 } }* whereas the function is being given a { i32, i64 }*. Probably the easiest way to work around this is a simple bitcast.
