[LLVMdev] Newbie question: Getting info about JIT-compiled function
Apologies if this is a FAQ. I am using the LLVM JIT facility on an x86_64 platform. I generate IR for a single function using IRBuilder(), use the FunctionPassManager to do some optimization passes, and then call ExecutionEngine::getPointerToFunction() to get a native-code version of the function. Everything works fine so far. Two questions: Question (1): How can I get the size of the native
