Quick dumb question:

I just installed gdc on ubuntu from apt. Which version of the dmd front end does it use?

gdc --version

gives me

gdc (Ubuntu 4.8.5-2ubuntu1~14.04.1) 4.8.5

For the lazy:

pragma(msg, __VERSION__);

void main() {}

That'll tell you.

It's hard to keep track of all distributions and what versions they
use, but I think in Ubuntu it is approximately:
gdc-4.8.x: 2.064
gdc-4.9.x: 2.065
gdc-5.x: 2.066
gdc-6.x: 2.068

The next gcc release ought to be an interesting experiment for the community, as although the version is still set to 2068, gdc has now diverged so far from the last C++ sources that it is anything but. I'll probably bump it to whatever version of phobos it can compile. :-)

Is there a possibility that gdc will continue to diverge? I don't necessarily think that's a bad thing, if upstream features can be implemented in a timely manner (that's a big "if" though).

Initially, the plan is to be aligned with stable branch in terms of sharing common C++ headers, then aligning any changes that alter the code generator.

The idea being that this will allow transition between C++ and D implementations to be seamless (no backend changes required).  We'll keep it in this state until a time when we are ready to switch.

My plan is that when the switch happens, we'll just continue to be in sync with stable, rather than a given release.
