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

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, 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) {

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!"

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

Hello, When I try to create execution engine I do get "*Interpreter has not been linked in.*" error and EngineBuilder returns NULL. Here is the line I use to create execution engine: auto executionEngine = llvm::EngineBuilder(std::move(m_module)).setErrorStr(&error).create(); Here are all headers I have included: #include "llvm/ADT/STLExtras.h" #include

Hi folks -- The comments in Function.h for Function::getArgumentList() state that the argument list is empty for external functions. This entails (I think) that it is not possible to determine the contents of the argument list of functions for which LLVM has only seen a forward declaration, for a given compilation unit. Is this correct? If this is the case, is there any way around this?

Ok. I figured out. Following methods needs to be called. That fixed the issue. llvm::InitializeNativeTarget(); LLVMInitializeNativeAsmPrinter(); LLVMInitializeNativeAsmParser(); LLVMLinkInMCJIT(); Aaron On Thu, May 10, 2018 at 8:33 PM, Aaron <acraft at gmail.com> wrote: > Hello, > > When I try to create execution engine I do get "*Interpreter has not been > linked

I believe the correct way is actually include the Interpreter’s header and the rest is handled automatically. Should be similar for MCJIT Zhang > On 11 May 2018, at 05:21, Aaron via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Ok. I figured out. Following methods needs to be called.

Hi , I am using LLVM for my Post Graduate course project on Optimization. I am trying to do some insrtumentation to the bytecode.I 've been going through your Instrumentation code for the past few days in /llvm/lib/Transforms/Instrumentation folder and finally found two ways of instrumentation : 1) injecting LLVM bytecode instructions 2) calling an external C function. I am trying both and

LLVM Command Line Library I'm proposing a heavy weight command line parsing and generating library for LLVM to replace Clang's parser and provide one for lld and any future tools that may need it. The scope of this library is slightly larger than what Clang has now, but not much. It is centered around the concept of a Tool. A Tool has a set of Options which can be parsed to Arguments or

Hi all, I am having some problem using the Function class. For my application, FunctionType is not known at the time I initialize the function. So, I just initialize the Function as return type void with no arguments. As I work on my function, I get to know the arguments and I insert the arguments in ArgumentList data structure of the function. The FunctionType is defined as const and I can't

This may be a a long shot but I'll ask anyway. Does LLVM have any way of mapping an Instruction or Value back to the original position (file, line number) in the source code? I'm writing a pass that among other things may detect some semantic errors in the way the user uses a particular API. I would like to report these errors to the user and identify the location of the error in the

Sorry to resurrect an old thread, but I finally got around to testing this approach (round tripping through bitcode in memory) and it works beautifully - and isn't that much slower than cloning. I have noticed however that the copy process isn't thread-safe. The problem is that in Function, there is lazy initialization code for arguments: void CheckLazyArguments() const { if
