Hi D community!

I'm here again, to describe what I've done during the third week of
Symmetry Autumn of Code.

## Restructuring the patch history

According to LLVM team, the [patch]( I
previously sent needs to be split into smaller ones and that is a bit
of a challenge. Why you may ask? Because looking at the [ABI
specification]( a lot of mangling nodes
are dependent of each other and splitting 3000 lines of code into
small, stackable and independent patches needs some planning. I tried
several layouts and
[this]( one
seems to work out the best, so I'm sticking with it.

Unfortunately, this week was kinda unproductive as I mostly spent this
week entirely restructuring the patch.

Because I'll only push the patches when they are done, for now, my work
is on
) branch, although bare in mind that this will constantly change, and
to fetch new changes you need to hard reset them when pulling.

## Fixing a bug on libiberty D demangler

During the restructure, I found out that anonymous symbols were not
correctly handled and skipped, according to the specification, so I
reported a [bug](
and sent a
) to fix the issue.

## Add fully qualified name on array DWARF tags

This is part of the milestone 2, but since I had
[this]( patch archived for a
long time I decided to push it on the weekend.

## What's next?

Next week I hopefully finish the patch split and finally push this to
the LLVM review platform. I'm also going to prepare some work for the
milestone 2 that includes analyzing some DWARF info that is currently
being generated by DMD/LDC/GDC compilers.
