[GSoC] Extending C++ Support in -fanalyzer - Final Report

Hi,

My GSoC 2026 project has come to an end, and I have put together the
various patches I worked on in this writeup along with other notes,
which serves as my final report for GSoC:

    https://riogu.github.io/posts/gsoc-2026

I also explain various concepts behind how the analyzer works, and other
concepts that are interesting to know when looking at the work done
(like how vtables are represented, how dynamic_cast works, and so on),
so it is a fairly complete view into my entire project.

Working on GCC in this format was a great experience, and I'm happy to
have had the opportunity to do more interesting work in new areas of GCC
I hadn't contributed to before. I go over my thoughts at the end of the
writeup so I wont repeat myself here.

If anyone reads the report and has feedback or comments (or found
mistakes in the writeup), feel free to email me or ping me on IRC. I'd
appreciate to know that people have read it.

I want to thank David Malcolm again for mentoring and reviewing my
patches, his help was very appreciated.

Thanks,
Egas
