+
+Hi D community!
+
+I'm here again, to describe what I've done during the twelfth week of Symmetry
+Autumn of Code.
+
+## LLVM upstream follow up update
+
+Two more patches in the D demangling patch train got merged!
+
+- https://reviews.llvm.org/D114308
+- https://reviews.llvm.org/D114309
+
+After getting my testsuite working reasonably well, I self merged those two
+accepted patches. I've contacted some LLVM members to figure out why buildbots
+were not reproducing my errors, and it seems some tests are not running on
+their testsuite, hence the error.
+
+I also amended some existing patches, accordingly with reviews.
+
+## Finishing implementation of basic types and continuing decoupling Clang-specific code
+
+I finished the implementation I had in mind to support at least one basic type
+(I choose boolean, just for testing it, being straightforward to implement the
+rest) with a Type wrapper called `DType`. Although, I'm not getting any output
+from the DWARF parser and `ParseTypeFromDWARF` function is not being called at
+all. I checked other language implementations, like Golang, but they are very
+outdated. I assume there is yet another entangled clang-specific stuff I still
+need to figure out or something I'm missing.
+
+You can see the changes here:
+https://github.com/devtty63/llvm-project/tree/lldb-d/implement-typesystem-d
+
+I made one more patch to move forward with clang-specific decoupling, in order
+to be able to support custom languages:
+
+- https://reviews.llvm.org/D115201
+
+I have more changes uncommitted that needs some tuning, including a DWARF to
+LLDB encoding helper, needed by language DWARF AST Parsers.
+
+## Simple Continuous Integration for LLDB-d
+
+I've been tinkering with some custom continuous integration for my llvm tree to
+provide automated builds to the community to test. So, I moved the repository
+to a new organization just to be able to have organization-wide self-hosted
+machines on Github actions. I already have a successful action working but it
+takes around 4h to complete, not including the actual testsuite, so I still
+need to revaluate the workflow and probably choose self-hosted machines for
+fast builds. Here are the workflows, if you are interested:
+https://github.com/devtty63/llvm-project/actions .
+
+## What is next?
+
+I will try to figure out why my current approach is not working as expected and
+if I get a successful output, I will start working on the DWARF dump system.
