After a month of work, it's time to post v2 of the Reflection patch series. Since v1, we checked in over 100 commits, wrote 5,000 LOC, added almost 50 tests and fixed about 10 existing FIXMEs.
The whole branch can be found at <https://forge.sourceware.org/marek/gcc/commits/branch/reflection> I will post v1/v2 diff as well. This patch series does not address the reflect.cc feedback. For that, wait for v3 in early January. We plan to merge the whole series in the first half of January. Bootstrapped/regtested on x86_64-pc-linux-gnu. -- >8 -- This patch implements C++26 Reflection as specified by P2996R13, which allows users to perform magic. This patch also implements related papers: Annotations for Reflection (P3394R4), Splicing a base class subobject (P3293R3), define_static_{string,object,array} (P3491R3), Function Parameter Reflection (P3096R12). (I already implemented consteval blocks back in July.) We also implemented some CWG issues that had been approved in Kona; e.g., CWG 3101, 3109, 3111, 3115, 3117. All metafunctions are implemented in this patch. The feature needs to be enabled by -std=c++26 -freflection. Some stats: the v1 patch was over 51,200 LOC which were written in ~335 commits. It came with over 400 tests with 11,722 static_asserts. We still had about 50 TODOs and FIXMEs in the code. v2 consists of about 56,000 LOC which were created in 440 commits. We now have 446 tests with 40 TODOs remaining. I'd like to thank: Jakub Jelinek, whose efforts can only be described as heroic and who never ceases to amaze me even after nearly 15 years of working together, he implemented many difficult metafunctions, annotations, mangling, converted our metafunction dispatch to using gperf, and so on and on; Jonathan Wakely for his libstdc++ patch review and generous & impeccable advice even at odd hours; Dan Katz for his work on the Reflection papers, writing Reflection tests for clang++ (many of which I've stolen^Wused), for his advice, bug reports, and generally cheering me on; Jason Merrill for his guidance, patch review, and, in fact, encouraging me to take on this project in the first place; Michael Levine, Valentyn Yukhymenko, and Alex Yesmanchyk for their nice contributions to Reflection; and Tomasz Kamiński for providing test cases, finding bugs, and answering my C++ questions.
