如何从LLVM中的CallInst获取函数名称？

I have an object of type CallInst. How can I get the called function name from it. Assume the function is called directly.

我有一个CallInst类型的对象。如何从中获取被调用的函数名称。假设直接调用该函数。

#1

StringRef get_function_name(CallInst *call)
{
    Function *fun = call->getCalledFunction();
    if (fun) // thanks @Anton Korobeynikov
        return fun->getName(); // inherited from llvm::Value
    else
        return StringRef("indirect call");
}

anyway, that's what the documentation implies:

无论如何,这就是文档所暗示的:

• CallInst
  • CallInst::getCalledFunction
• returns Function
• and walk back up the inheritance graph until you see a plausible candidate:
  • Value
  • Value::getName

然后重新继续继承图,直到看到一个似是而非的候选者:Value Value :: getName
