Update frontend to DDMD v2.076

Nothing to say here, only: 😀 😢 🤔 🤓 😬 😨 😱

It looks like we are passing the testsuite now. :-)

Congrats, and thanks for your amazing work.

This should go in a new branch perhaps. Bootstrapped builds are also not yet working.

OK. I just reviewed the changes to the GCC patches, configure/makefiles and glue code and these look fine so far.

What's current status @ibuclaw? What remains to be done until GDC can finally switch to ddmd and you can start to follow dmd's release schedule? I'm hopeful that due to the much smaller front-end diff one day we may be able to setup some automatic merge, build and test of dmd/druntime/phobos pull-requests with GDC on of the CI services that we use. #wishlist2018

Stage 3 builds weren't quite working yet (bootstrapped builds) and it needs a rebase. Probably the only two things that need to be addressed.

[ibuclaw]

Improvements that should be looked into:

• Link gdc against libgdruntime, not libgphobos.

And things that would save time building:

• Investigate if libgphobos part can be compiled only during stage3, in the last step after the compiler is build.
• Investigate if libatomic and/or backtrace bootstrapping can be moved to toplevel configure, as if it's not used by druntime, then it's not required for bootstrapping.

Link gdc against libgdruntime, not libgphobos.

Which looks like it will require support in the driver, both for linking druntime statically and using the generated libgphobos.spec file for adding all dependencies.

I think I just have a couple more patches to push to master, then let's just rebase and go with this.

configure: error: GDC is required to build d
make: *** No targets specified and no makefile found. Stop.

@braddr - gdc is required to be installed on the build servers after this is merged. I've been testing with gdc-7 and gdc-8 and all works fine.

Alternatively, you could build with GDC=dmd, should work also, but untested as of yet.

Though maybe not, as dmd wouldn't understand options like -no-pie.

Time to venture the point of no return?

of @noreturn. Yes 🥇
