In >your LLVM code, you will have to first cast your function pointer before >storing it, but it should work as you have it. 1) Can a modified version of ParseAssemblyFile(InputFilename) that takes a pointer to LLVM code in memory instead be used to generate a Function* for use by the getPointerToGlobal()? I understand that it currently returns a Module*. Is it possible to make it return an F* instead, and if so how would the implementation roughly look like? 2) C...

...inked list" error when "my llvm-as" works,however,when I do nothing on the disassembled bitcode file,everything is OK, After debugged,I found the error line is "MemoryBuffer *F = MemoryBuffer::getFileOrSTDIN(Filename.c_str(), &ErrorStr);" in the "Module *llvm::ParseAssemblyFile(const std::string &Filename, SMDiagnostic &Err,LLVMContext &Context)" function, I don't know the reason,anyone once got the similar trouble? Thanks

Hello all, I am trying to generate a module object using something like this: (to use for code analysis) Module *topModule; SMDiagnostic error; topModule = ParseAssemblyFile("code.s", error, getGlobalContext()); displayErrorInfo(error); void displayErrorInfo(SMDiagnostic& err) { std::string errFileName = err.getFilename(); std::string errMsg = err.getMessage(); std::string errLineContents = err.getLineContents(); int errLineNo = err....

Hi All, Could I read .ll file as module to get its functions in ModulePass could it be like readModuleFromFile(M.ll) or whatever?

I have an application that is generating llvm assembler text files, these are then loaded with ParseAssemblyFile. I am also using ExecutionEngine::runFunction to call functions in the loaded/created modules. Can I place references to external functions in the assembler files? For example I if my application has a function called fred() I would like to place calls to fred in the assembler text file. Can I do...

Hi, everybody: I am a beginner with LLVM, in fact today was the first day that I use it. I have several questions about LLVM: Can I use LLVM to compile several files (bytecode), scripts (char*) and link them with external libraries generating *only* one executable (all in memory)? Can I invoke externals functions from a guest (LLVM generated) code which exist in the host code (the code that

Thanks! Problem is though, that the Ruby compiler is integrated in the compilation of the program being executed, to be able to parse & compile dynamic code at run-time. Therefore the calls to ExecutionEngine::getPointerToGlobal(F) need to be made in LLVM code. Here is a detailed simplistic example in pseudocode of what we want to do: First Ruby code is entered at run-time, received as a
