[LLVMdev] the definitions of internal functions and external functions

[huwei8717]

Hi, 

I have a llvm pass in hand written by other people. There are following statements that I couldn't understand:

-------------------------------program----------------------------------------------------
...
  // Calls to internal functions.
  if (!F->isDeclaration()) {
    DOUT << " internal call" << opcode << ": " << name << "\n";
    return ...;
  }
  // Calls to external functions
...
-------------------------------------------------------------------------------------------

My question is:

What's the definitions of internal functions and external functions? In c, internal functions is functions that it is only called in the file where it defines using keyword "static", external functions is functions that can be called by other files, defining using keyword "external". Are these definitions identical with the definitions in llvm? 

Thank you very much.

Best Regards
