Generating vtables and typeinfos about implib.so HOT 7 CLOSED

That's an interesting one. Leaving complexities of parsing Itanium ABI aside, adding wrappers for vtables would require adding stubs for all virtual methods referenced in them. This is possible iff each virtual method is exported which is not always true: methods might be hidden via __attribute((visibility("hidden"))) or simply -fvisibility-inlines-hidden. So I'm afraid in general the answer is "no".

from implib.so.

In theory if virtual method is hidden we could still lazily read it's address from library's vtable at runtime using offset from vtable start. But I'm still not sure how to identify if a given unnamed vtable entry is atually a method (vs typeinfo or virtual offset).

Generating these symbols could be optional. If required symbol is missing (not exported) the tool could just report an error.

Ok, I should be able to support a limited use-case. It's kind of non-trivial thing to add/debug so might take time to add though.

That would be great. Thanks a lot!

Please check ToT, I've added vtable support and it seems to work in simple cases.

Thanks, I'll give it a try
