...Where you tweak MyExternalFn to have the desired prototype. To create a function declaration: From C++, simply call Function::Create and then do not add any basic blocks. From LLVM assembly, use the keyword "declare" instead of "define": http://llvm.org/docs/LangRef.html#functionstructure If you're using the JIT, you'll need to do the above, but also may need to register your functions using ExecutionEngine::addGlobalMapping. http://llvm.org/doxygen/classllvm_1_1ExecutionEngine.html#a8 Note that the C calling convention do not map directly to LLVM IR for many cases,...

Hello, I got very interested in LLVM project, and I decided to start writing my own scripting language based on it. By studying the documentation, I could not find how to call external function, written in C. That is, I have a set of functions written in C/C++, I generate code, using LLVM C++ interface, how can I call(or register in machine in run-time) my external functions? Maybe I just missed

Is it possible to use address of function in case block of switch instruction? I understand that it should be constants only, but in llvm reference i founded that: "The addresses of global variables and functions are always implicitly valid (link-time) constants. " Yours sincerely, Kadysev Mikhail -------------- next part -------------- An HTML attachment was scrubbed... URL:

Sorry, still a bit confused. Say we have two basic blocks: A and B. B has a label. There is no branch/control flow instructions explicit uses B. like this: A: code sequence does not contain br/other control flow instruction B: lable_of_b: code sequence Is A still a predecessor of B?
