Motivation
----------
1) It's required for Walter's work on using -betterC for the
backend conversion:
https://github.com/dlang/dmd/pull/6907
That is only a putative dependency. Indeed the -mv=<pkg>=<file>
feature is useful.
If it's just about the backend though, there is a straightforward
solution.
If we insist on having a backend package (not under dmd)
```
module backend.cod1;
```
then we can simply move the package to the right place
```
mv src/dmd/backend src/backend
```
. Imports of dmd from backend obviously forbidden (should be
enforced by separate compilation).
2) We start to run into random failures lately, e.g.
https://github.com/braddr/d-tester/issues/63
https://github.com/dlang/dmd/pull/7569#issuecomment-356992048
3) There's also WIP to move dmd-cxx to 2.076.1:
https://github.com/dlang/dmd/pull/7595
We've been through bootstrapping discussions a couple of times,
so let me repeat what was decided when we made the frontend
switch from C++ to D.
- Other platforms are bootstrapped by cross-compilation.
- DMD must be compilable with the latest stable/major release of
dmd, ldc, and gdc.
To enforce this policy the Travis-CI test was set up.
Hopefully this original purpose of the Travis-CI hasn't been
forgotten in the meantime.
- No other guarantees were negotiated.
Sticking to an ancient compiler defeats the eat your own
dogfood goal underlying the C++ -> D transition.
The latest released frontend versions are at the moment:
2.078 - dmd (2.078.1)
2.077 - ldc (1.7.0)
2.068 - gdc (6.3.0+2.068.2)
So technically we could only upgrade to 2.068 atm.
Would be good to hear some release plans from the GDC team for
this year.
==========
Just in case this is what dmd's schedule looks like for 2018.
2.078.0 - 2018-01-01
2.079.0 - 2018-03-01
2.080.0 - 2018-05-01
2.081.0 - 2018-07-01
2.082.0 - 2018-09-01
2.083.0 - 2018-11-01
2.084.0 - 2019-01-01
I wished the semver discussion¹ would have been a bit more
decisive and we'd started out the year with 8.0.0 (majors every 6
months, minors every 2 months). Hopefully we take the chance of
relabeling 2.080.0 to 8.0.0.
