Front-end with support for custom __attribute__'s

Clang Frontend
1

Is it possible to create custom Clang frontend supporting new types of __attribute__ without
modification of Clang libraries?

As for attributes, I've read "How to add an attribute" manual, but (AFAIU) it requires modification
of Sema::Kind enum, and even if I inherit from Sema, I won't be able to replace existing Kind
without breaking API compatibility of my Sema derivative with other libraries.

Any suggestions?

You might be able to use the "annotate" attribute for what you're doing. If that doesn't work, then the answer is "no": attributes need to have explicit code to support them in the parser, sema, AST, and code generator.

Thank you for your help. I hope "annotate" will work for me.
