Thanks for all of your efforts, Iain!!

Compilation time has been reduced from around 40 to 0.08

55MB. (Thanks BorisCarvajal!)

Wow. That's a pretty major improvement! Is this improvement
upstreamed?
It was backported from this PR
https://github.com/dlang/dmd/pull/11303 (see PR 11335)
Just out of curiosity, which language version will the next GCC
release have? Currently, my version of GDC gives __VERSION__
as 2.076, which is pretty old (whereas LDC gives 2.093,
basically on par with DMD). Will the next GDC major release
have a significantly-updated language version?
Likely the deciding factor will come down to how much free time I
will get to do so. There's still a few outstanding issues in
dmd-master and gcc middle-end that have hampered progress by a
few weeks.
(I understand that the original plan was to get a foot in GCC's
door first, for bootstrapping reasons, then now that we have
GDC in the official GCC distribution, we can bootstrap to a
much more up-to-date front-end version.)
That is correct, so far I've yanked out the old C++ sources and
replaced them with D, and the end result is a compiler that links
and passes 99% of the testsuite. Though I wonder if it might be
possible take advantage of GCC's bootstrap process and keep both
in-tree for the benefit of incomplete ports.
