similar to: [LLVMdev] Function::getArgumentList() question

Hi, supposing I have a function “foo” like the following: int foo(int a, int b) { ... ... } I want to insert int the LLVM IR a call instructions to a function “bar” that requires the same parameters of foo. So my function foo will become: int foo(int a, int b) { bar(a,b); … ... } I am using the following code: bool ThreadSanitizer::runOnFunction(Function &F) {

I am trying to generate a simple wrapper function: Function* pWrapper = m_module.getOrInsertFunction(name, FunctionType::get(Type::VoidTy, vector<const Type*>(1, PointerType::get(Type::IntTy)), false)); How do I actually get the Value* for the one argument to this function? The pWrapper->getArgumentList().size() is 0. Shouldn't the argument list contain the Value*

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

Hi all, Recently I have implemented a transformation pass based on LLVM3.5 and its function is to duplicate the function's argument list in a bytecode file and replace all use of original function with modified function. In LLVM3.5, the pass can work properly. However, when I tried to transplant the pass to LLVM3.9, the error "Argument value does not match function argument type!"

Dear All, I need your help urgently I have to copy the CFG of each function using CloneFunction or CloneFunctionInto. After I made the copy function. Print the basic blocks then get this error : While deleting: i32 % Use still stuck around after Def is destroyed: %mul2_ = mul nsw i32 %6, 3 Use still stuck around after Def is destroyed: store i32 3, i32* %x_, align 4 opt: Value.cpp:75: virtual

Hey All, I’m working with Mac OS X 10.10, and everything seems generally fine but when I started working on a FunctionPass I get the following: error: call to deleted constructor of 'Function::ArgumentListType' (aka 'iplist<llvm::Argument>') Function::ArgumentListType argList = f.getArgumentList(); Any pointers as to the correct way access the Arguments of a

Hi all, I am trying to extend a FunctionType to include new parameters. In particular, I want to ensure that the main function has been declared with both argsc and argsv. However there seems to be no easy way to accomplish this: llvm::Function::getFunctionType() returns a a reference to a const object, while modifying only the argument list yields an error during verification since the

All, I'm seeing duplication of DICompileUnits in a pass that worked in 3.8. I assume I'm doing something wrong. Would someone be willing to point me in the right direction? The below minimized pass reproduces my issue in 4.0 with the following error: DICompileUnit not listed in llvm.dbg.cu !1707 = distinct !DICompileUnit(language: DW_LANG_C_plus_plus, file: !1, producer: "clang

Does cloning copies the function with its address or it constructs a new address to the new function? Is this real copying for the CFG or just opaque one to do some work? If it's not real copying, please I need a method that can help me in copying the function in another with new pointer to another address. Please I need answer urgent Thanks On 29 May 2013 10:14, Rasha Omar <rasha.sala7

Sorry i'm using the following code: F = (cast<CallInst>(BI))->getCalledFunction(); for (auto& A : F->getArgumentList()) { errs() << "------- " << A.getName() << " " << "11" << "\n"; } But how can I get the parameters (as e and f in the example)? Thank you and best, Mo On

Thank you. What I need to do to address this? Open an issue on bugs.llvm.org? I'm not sure what the fix needs to be in the cloner.

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

Artur, > OK, I just need the same signature for both of those instructions. Both are callinsts of same function, isn't that enough? Since it's a variadic function there is also a bitcast to proper type. So, looking for type of callee (not result, but function type!) you'll obtain the real "signature" of callee and if you'll strip all pointer cast you'll obtain the
