Hi All, I am working on writing pass in LLVM and interested in doing function permutation at intermediate representation byte code level? If I have lets say C program having three functions and its corresponding IR bytecode. void findLen(char a[10]) { int tmp = strlen(a); printf("Len is : %d\n", tmp); } void muladd(int a, int b, int c) { int tmp = a + b; int tmp1 = tmp *

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 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/

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

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())

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 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

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, 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()),

Hi everyone, I am building a function that would call a function in another module, I found this related thread http://llvm.1065342.n5.nabble.com/Using-a-function-from-another-module-td10506.html All my functions have prototype int f(myStruct * c); here comes my problems If I have Function* f1,*f2 f2 is in another module, f1 is the function I am building.

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

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

That's not being generated by the CreateCast, so it looks like your description of the problem was quite misleading. Ciao, Duncan. >

So what do you think the problem is? Thank you.
