+
+Hi D community!
+
+I'm here again, to describe what I've done during the fourth week of Symmetry
+Autumn of Code.
+
+## Finishing the patch split
+
+I'm happy to announce the full list of patches since the split:
+
+- https://reviews.llvm.org/D111414
+- https://reviews.llvm.org/D111415
+- https://reviews.llvm.org/D111416
+- https://reviews.llvm.org/D111417
+- https://reviews.llvm.org/D111419
+- https://reviews.llvm.org/D111420
+- https://reviews.llvm.org/D111421
+- https://reviews.llvm.org/D111422
+- https://reviews.llvm.org/D111423
+- https://reviews.llvm.org/D111424
+- https://reviews.llvm.org/D111425
+- https://reviews.llvm.org/D111426
+- https://reviews.llvm.org/D111428
+- https://reviews.llvm.org/D111429
+- https://reviews.llvm.org/D111430
+- https://reviews.llvm.org/D111431
+- https://reviews.llvm.org/D111432
+
+This includes some little changes and it already have a ton of discussion! Some
+things are little disappointing and other somewhat rigid, in my point of view,
+since some patches are "too atomic" according to the reviewers. Some other
+stuff, however I totally understand, since it increases the overall LLVM code
+quality, even though being nit picking. I'm going to try to circumvent the
+issues and strive to push this forward as much as I can.
+
+## Reflected GCC Patches
+
+By reading the code twice, during the split, I found out some other stuff
+considered interesting to change on the GCC side, so I made some patches:
+
+- Usage of distinguishable tuple(), instead of wrong templated Tuple!():
+ https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581577.html
+- Write distinguishable variadics and add missing tests to the test suite:
+ https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581574.html
+- Add test cases for missing coverage tests:
+ https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581588.html and
+ https://gcc.gnu.org/pipermail/gcc-patches/2021-October/581590.html
+
+I also generically answered previously submitted patches and resubmit some
+malformed/wrong patches I made, with some help by Iain.
+
+## Announcement on the `llvm-dev` mailing list
+
+I announced the D demangler change into llvm-dev mailing list, as requested by
+LLVM reviewers. If you want to interact and discuss there, feel free to do it
+so: https://lists.llvm.org/pipermail/llvm-dev/2021-October/153267.html
+
+## Minor updates on GCC bugzilla
+
+I added this missing bugzilla report:
+- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102702
+
+Since Eric Gallager added me to CC list for various fuzzing issues to GCC
+demangler, I decided to create an issue about the time complexity problem,
+https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102732 , similar to what was
+reported by c++ demangler (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80002).
+
+## What's next?
+
+Next week I'm going to keep an eye on the patches and fix the suggested
+changes, as usual. About the next milestone, I already have some drafts about
+things to look at and differences between compilers DWARF generation. I also
+have an hint of how to implement it, so probably I'm going to work on some
+draft implementation. Because the demangler is already ported/implemented, just
+reviewing is necessary, I think I can move forward with a draft implementation
+of the next milestone, although this is something I need to discuss with my
+mentor. On the meanwhile, I made my TODO list open and automatically deployed,
+at least daily, so you can see what I'm doing during the week
+[here](tasks.lsferreira.net) .
