Getting the unique ID for a clang::Decl

+1 to that.

Sometime ago, I tried to get an unique ID generated by clang but couldn’t find any .get_whatever() to solve the problem.

I ended up using the pointer’s address as an ID, as it seems to be unique.

For example:

const clang::TagDecl &tag;

std::size_t address = reinterpret_caststd::size_t(tag.getFirstDecl());

It’s basically the same code for all decls. I use getFirstDecl to avoid having different IDs for the same decl.

If there is a better way to do that, I would like to know too.

Thank you,
