||
| ## Overview | ||
|
|
||
| Thanks again to [Open Source Security, inc](https://opensrcsec.com/) and | ||
| [Embecosm](https://www.embecosm.com/) for their ongoing support for this | ||
| project. | ||
|
|
||
| ### Milestone Progress | ||
|
|
||
| The focus for this month was the upstreaming of all `gccrs` commits | ||
| which affect common GCC parts, in order for our subsequent work to be | ||
| upstreamed properly. These patches are essential, as most of the work we | ||
| have done this year relies on them: Error codes, for example, require | ||
| changes to the error emitting framework within GCC. The procedural macro | ||
| work, which was the subject of Pierre-Emmanuel's internship, relies on | ||
| changes to the GCC build system in order for our set of Rust libraries | ||
| to be built when building the Rust frontend. We are almost done fixing | ||
| reviews from the GCC maintainers, and most of the commits aforementioned | ||
| have been pushed to GCC's `trunk` branch already. We will now continue | ||
| the upstreaming of commits, by sending over 800 patches to `trunk` in | ||
| the following weeks. This work needs to be completed before the end of | ||
| the GCC 14 development stage, which should happen sometime in May 2024. | ||
|
|
||
| The upstreaming of patches is however a time-consuming task, and coupled | ||
| with vacations, GNU Cauldron and the disappearance of our GSoC students, | ||
| only 35 pull-requests have been merged to the `gccrs` repository this | ||
| month. Nonetheless, we are on track and are happy with the progress of | ||
| the compiler. The technical work that has been merged this month focused | ||
| on compiler intrinsics, as well as backend cleanups. Furthermore, a | ||
| longstanding cross- compilation issue has been fixed, allowing some of | ||
| our early `gccrs` users to continue using the compiler for Dreamcast/SH4 | ||
| development. | ||
|
|
||
| The main event this month for `gccrs` was GNU Cauldron, during which | ||
| Pierre-Emmanuel Patry gave an amazing talk detailing the progress of the | ||
| frontend as well as some technical details regarding procedural macros. | ||
| You can find the slides for this talk | ||
| [here](https://github.com/Rust-GCC/Reporting/blob/main/Cauldron%202023.pdf). | ||
| The next talk we will give will be at EuroRust 2023, in a couple of | ||
| weeks! | ||
|
|
||
| ### Community call | ||
|
|
||
| We will have our next monthly community call on the 9th of October 2023. | ||
| You can subscribe to our calendar to see when the next one will be held. | ||
| The call is open to everyone, even if you would just like to sit-in and | ||
| listen. You can also subscribe to our | ||
| [mailing-list](https://gcc.gnu.org/mailman/listinfo/gcc-rust) or join | ||
| our [Zulip chat](https://gcc-rust.zulipchat.com) to be notified of | ||
| upcoming events. | ||
