  Hi,

The implementation of the D front-end in GCC is based on the original
C++ version of the D programming language compiler, which was ported to
D itself in version 2.069.0 (released in 2015).  To keep it somewhat
up-to-date, I have been backporting fixes from upstream back into C++,
but this stopped at version 2.076.1 (released in 2017), and since then
I've only been keeping the front-end only updated enough to still be
able to build the latest version of the D language (now 2.098.0).

Reasons for putting off switching to the D implementation immediately
after GCC 9 has been a mixture of the front-end not being ready to use,
and current portability status of the D core runtime library.

It has come to the point now that I'm happy enough with the process to
switch out the C++ sources in gcc/d/dmd with D sources.

Before that, there's only this patch that makes the required changes to
GCC itself in order to have a D front-end written in D itself.

The rest of the series only changes code in the D language front-end or
libphobos standard library, so I've left that out for the time being
until I'm ready to commit it.

The complete set of changes are in the ibuclaw/gdc branch under
users/ibuclaw.  It has been well-tested on x86_64-linux-gnu for about 3
years now, and I've also been testing the self-hosted compiler on
powerpc64le-linux-gnu as well with no regressions from the D language
testsuite run.

Does anything stand out as being problematic in this patch, or may need
splitting out first?  Or would it be OK for trunk?

Thanks,
Iain.

Hi,

It would be good if can get some traction on this.  There's a reasonable amount of anticipation to get the D front-end up-to-date with the latest language version, rather than be a number of years behind.

Regards,
Iain.

Presumably this means that the only way to build D for the first time on 
a new target is to cross from an existing target that supports D, right?

I think that's not unreasonable and I don't think we want to increase 
the burden of maintaining an old codebase just for the sake of a 
marginally easier bootstrap process for a new target.

So I think you should go with this whenever you're ready.

There should be some sort of note about this in the documentation,
IMO; both install.texi and the "Caveats" section of
gcc-12/changes.html (and possibly other places).

Congratulations: self-hosting compiler!

That, of course, makes the GCC/D compilation process more difficult:

(Some may argue "burden" vs. "marginally", but yes, I agree.)  Plus, the
problem that also for non-cross (native) builds, you now have a baseline
GCC/D compiler requirement:

> There should be some sort of note about this in the documentation,

That has been done.

    +In order to build GDC, the D compiler, you need a working GDC
    +compiler (GCC version 9.1 or later), as the D front end is written in D.

> and the "Caveats" section of

That not yet, but yes, I agree that should be done, too.

So it's now a requirement to build/bootstrap GCC/D with GCC 9.1 (or
newer, of course) -- which is quite different from the current GCC 4.8
requirement for all other GCC parts (including self-hosted GCC/Ada, by
the way, which also is happy with GCC 4.8).

I'm one of those (few, I guess?) doing bootstrap verification builds with
actual old GCC 4.8 ("gcc-4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.4) 4.8.4",
precisely), and that now obviously doesn't cover GCC/D anymore, for
example with '--enable-languages=all' (and without the GDC 4.8 packages
installed):

    [...]
    +checking for gdc... no
    [...]
    +configure: WARNING: GDC is required to build d
     configure: WARNING: --enable-host-shared required to build jit
    -The following languages will be built: c,ada,c++,d,fortran,go,lto,objc,obj-c++
    +The following languages will be built: c,ada,c++,fortran,go,lto,objc,obj-c++
     *** This configuration is not supported in the following subdirectories:
    -     target-liboffloadmic
    +     target-libphobos target-zlib target-liboffloadmic
         (Any other directories should still work fine.)
    [...]

..., or error for explicit '--enable-languages=d'.

So I built myself a stock GCC 9.1 with '--enable-languages=d', and via
'[...]/configure [...] CC=gcc-4.8 CXX=g++-4.8 GDC=[GCC 9.1]/bin/gdc [...]'
I'm able to successfully bootstrap GCC, including GCC/D, in a mixed
GCC 4.8/9.1 configuration, with subsequent good-looking 'make check-d'
results.  Per my superficial review of the build log file, the
'[GCC 9.1]/bin/gdc' indeed is only used during stage 1 build, as it
should be.  So that's good enough as far as I'm concerned, and unless
anyone sees any reason why such a mixed GCC 4.8/9.1 configuration would
be bad, may it be worth putting such information (may 'configure' with
'GDC=[GCC 9.1]/bin/gdc') into the documentation, too?
