Hey!

I'd like to write a program that collects statistics of OpenCL kernels. Examples

are the number of arithmetic operations, number and types of variables, etc. In

the future I'd also like to do some static analysis, for example to try and

derive memory access patterns.

I'm new to Clang, so I'm not quite sure how to go about this... It seems like

the RecursiveASTVisitor class could be a good start, as it allows you to

traverse the AST. Overloading VisitStmt() for example would allow me to count

the number of arithmetic expressions, right?

Unfortunately I can't figure out how to start the tree traversal. What is it

that I need to pass my visitor class in order to traverse the whole file or a

certain function?

Are there any examples that show a usage of RecursiveASTVisitor?

Thanks

Dominik
