I'm not really sure what happened but replies from <lsferreira at
riseup dot net> is apparently getting ignored by the mailing
list, including this report :/ Can someone verify it? Anyway, for
people that follow my blog, I posted this 2 days ago. I'm going
to post via the web interface, for now.
Hi D community!
I'm here again, to describe what I've done during the eleventh
week of Symmetry
Autumn of Code.
## LLVM upstream follow up update
Three more patches in the D demangling patch train got merged!
I joined this week on the LLVM official team to help provide
maintenance on the
code I introduced and planning to introduce as well as general
changes made for
D in the official tree.
I have 2 more patches already accepted about the demangling but I
them yet, as I'm having some problems on running the test suite
Currently, LLVM already supports special D main, simple multiple
and anonymous symbols. Next step is to support basic and compound
although I think this needs to be split up, as discussed in some
## Implementation of basic types and decoupling Clang-specific
I started this week implementing basic types on the D TypeSystem,
the meanwhile, I found that some decoupling is needed, since the
architecture for parsing debug info has some entanglement with
structures such as the AST Context and other TypeSystem and AST
structures. I though this was something already considered, but a
lot of effort
on this was left behind when other languages stop being
supported, like Go.
I made some patches to move that forward in the upstream:
Still about the decoupling, I found out that only DWARF Parser is
decoupled, but other debug info parsers like
are really entangled with the Clang TypeSystem. There is no
at the moment, and I plan to decouple that as well, although, it
is not really
a priority for me, since my main development environment is
Linux. That said,
I'm probably going to left Windows support as a second priority,
I added those patches to the
created last week and continued working on it.
## What is next?
I haven't finished the type wrapper to represent a D type, due to
decoupling issues. I will hopefully finish the implementation
next week and try
to have some simple output on the LLDB side.
