Here are some issues that I am unclear about. What would be great is if the answers could be incorporated into the comments and documentation for DIFactory and DebugInfo.h: 1) What types of DIScope are valid arguments for DebugLoc::get()? The method takes an MDNode* argument, so looking at the function signature is no help. For example, DIFile is a subtype of DIScope, however looking at
