[LLVMdev] [cfe-dev] Do you use UML utility programs?

Hello Sean Silva and List,

I've got an incomplete idea about implementing a utility which
extracts such diagrams automatically. And guess that there should
exist one already.

Let's say I want to draw a seq. diagram of an application.
- To draw the diagram I compile the application with a modified
version of clang/llvm.
- This modified clang/llvm inserts some extended llvm intrinsic
function calls into start and end of every functions.
- Then I execute the application for the scenario needed to draw the
seq. diagram for the application.
- Executing the application generates a binary file.
- A utility like any other llvm utility reads the binary output file
and draw seq. diagram of the application for the tested scenario.
- The utility which draws the seq. diagram is easily configurable.

I think, to do this, a set of extended llvm intrinsic functions which
print out logging message of each function calls/returns must be
And this intrinsic functions can be added via llvm optimization pass.

This is my brief and incomplete idea.
And I think this could also be an item of patent if is not registered ever.
But I believe not. This is so simple and easy. There should exist
already implemented software which does this better. Maybe Rose or
stuffs like this I doubt.

I'd like
- to know if there exist one or some similar to my idea. (Regardless
of weather it is based on llvm)
- to know if my idea is realistic and possible?

I wish I could implement this myself.
