Awesome work, thanks! Already available on Arch Linux indeed,
just typed objdump as per your post and it worked. Editing my
dmd.conf right now.

Hi,
I'm not sure when it was announced, but binutils 2.25 has been
released! There's a small reason for excitement as it is the
first to come with D demangling support in the GNU toolchain.
Unfortunately, I forgot to send in patches that actually
document it! So for the moment, it's a little secret feature
shared between all who may read this. :o)
How do you use it?
---
By default, binutils programs will treat all mangled symbols as
C++, however you can override this by using --demangle=dlang,
eg:
objdump -d --demangle=dlang prog.o
nm --demangle=dlang ddmd
You can also kickstart your usage by putting -L--demangle=dlang
in your dmd.conf, and watch your obscure linker errors turn
into pretty function signatures.
How do I get it?
---
The release itself is a source package, however a safer choice
is to get the release binaries through your Linux distributor.
Fortunately, there have been distributions who have been
shipping it as early as three weeks ago.
Archlinux users: I'd imagine this is available to use now.
Ubuntu users: You'll have to wait until April with the 15.04
release.
Bugs and Fixes
---
Whilst the demangler is able to handle all things core.demangle
can do (and a little bit more!), a small test of running nm
against the ddemangle program that gets shipped with dmd 2.066
shows that there are still plenty of complex template symbols
that it still can't manage. The implementation itself is
pretty straightforward to follow, well documented and written
in C. Volunteers who wish to help out getting as close to
99.99% coverage as possible are welcome!
Enjoy!
Iain.
