||
| ## 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 | ||
|
|
||
| We spent the majority of our time this month preparing patches, or | ||
| fixing them after receiving reviews on the mailing lists. Some of these | ||
| patches take a long time to upstream and review, as they touch common | ||
| complex parts of the GCC project such as the build system, which we are | ||
| currently fighting with to integrate a new `libgrust` folder containing | ||
| various libraries useful to `gccrs`, such as those related to our | ||
| procedural macros implementation. These patches are necessary to | ||
| upstream before the rest of the work done this year, as intrinsic | ||
| compiler features have been moved to this directory. Once this is done, | ||
| we will be able to simply push the new patches upstream, after short | ||
| modifications to make them more suitable to the upstream GCC project. At | ||
| the moment, there are around 900 patches being prepared, with the hope | ||
| of pushing them before the end of the month. We are also exploring | ||
| solutions to help automate this process a little more, as it represents | ||
| very time consuming work which we would like to avoid in the future - | ||
| keeping `upstream` up to date with our development repository, with | ||
| weekly or bi-weekly updates, should prove worthwhile in the long term. | ||
|
|
||
| On the technical side, a lot of bugs were fixed this month again thanks | ||
| to our contributor team. [Jakub Dupak](https://github.com/jdupak) has | ||
| been making some amazing progress on borrow-checking in `gccrs`, with | ||
| the development of a new, simplified intermediate representation | ||
| specifically designed to interact with the polonius borrow-checker. At | ||
| the moment, our compiler can start emitting simple errors, such as "use | ||
| after move" errors, or simple lifetime analysis, which we are really | ||
| excited for. | ||
|
|
||
| We also got in touch with the GCC release maintainers to understand what | ||
| was expected of `gccrs` for it to be an integral part of the GCC 14.1 | ||
| release, and should be able to fulfill the requirements (`println!()` | ||
| macro, simple Rust examples working…). We are very excited for everyone | ||
| to be able to try the compiler. | ||
|
|
||
| Finally, October also saw Pierre-Emmanuel and Arthur go to EuroRust, | ||
| where they had an amazing time. We are looking forward to coming back | ||
| next year. We gave a small talk on the compiler, and the challenges of | ||
| compiling the standard Rust library, which we will link to once | ||
| released. | ||
|
|
||
| ### Community call | ||
|
|
||
| We will have our next monthly community call on the 13th of November | ||
| 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. | ||
