title: Debugging without using source file in LLVM
body: <p>LLVM debugger (<code>lldb</code>) uses a source file for debugging (e.g. for breakpoint). I want to use <code>lldb</code> without having source files, only with intermediate representation files (<code>.ll</code> files). </p>
  
  <p>Is it possible? If not, can I do that with <code>gdb</code> debugger? Is there another idea?</p>
