Hi,

I am proud to announce a new major GCC release, 15.1.

The D frontend now supports version 2.111.0 of the D programming language and run-time library.
On supported targets, the version GNU_CET is now predefined when the option -fcf-protection is used. The protection level is also set in the traits key __traits(getTargetInfo, "CET").
A new option -finclude-imports was added, which tells the compiler to include imported modules in the compilation, as if they were given on the command-line (analogous to dmd -i).

As and when DMD releases v2.111.1, it will be merged into GCC 15.2. Likewise regression fixes beyond v2.1xx.y will be backported into future minor releases for the next three years.

An online version of the GDC documentation and man pages are available here (also in PDF or PostScript or an HTML tarball)

For the full list of notable changes in other languages and targets, see the GCC 15.1 changes page.

This source release is available here, or from any of the WWW and FTP servers listed on the mirrors page (the release is in the gcc-15.1.0/ subdirectory).

If you encounter difficulties, while you may contact me directly, it is better to visit https://gcc.gnu.org/bugzilla and file a problem report.

GCC 16 development

Now the development cycle has started again, usually it would be time for the next round of have ambitions for changes to land during the next release cycle. However due to current circumstances (documented here), there likely won't be too many big changes being made over the next 6 months. With that said...

The "in-memory" preprocessing of C sources for ImportC is expected to land soon after being brewed in the cauldron for a couple years, though it will initially be without all predefined target macros being available. So some system headers will not be cleanly importable as-is.
For target specific built-in defines, GCC internally has three ugly macros which are not usable with any front-end language apart from C/C++. So the aim is to rewrite this part of the GCC back-end to expose them as common target hooks, then everyone benefits, not just D.
GDC will continue to be in sync with current DMD development throughout the release cycle so that the next version of GCC will also sport the latest release of the D language, whatever that release version will be.

There are - as always - more things to do than I have available hours to do them in, but if you feel you could help in any way, please don't hesitate to jump on the #gdc channel on the Dlang Slack or #d.gdc on Libera.Chat IRC.

If you are interested in helping support the on-going development of GDC, you can do so by making a donation to the D Language Foundation.

Finally, a big shout out and thank you to the kind sponsors over the years. You are all awesome.

Until the next major/minor release...

Regards,
Iain.
