Thanks for taking the time to write up a CFP; we'd be overjoyed to have you present at LLVM Distributors Conf 2021! If you still plan on presenting, this is a reminder to get started on your slides for next week. Once they're done, we will contact you about submitting a PDF of your slides as either a pull request to this repository or via email to the organizer. We hope to have a schedule finalized by EOW; we may iterate on the schedule based on whether presenters have conflicts. Please keep this issue open for attendees to ask questions, or close this issue if you no longer plan on attending. Reminder to keep your talk concise (15 minutes); we wont be doing time for questions in order to fit as much content as possible. Attendees should ask questions here in this github issue.
Great work Hans! We are doing the same as Mozilla now for Firefox!
Title
Building, Testing, and Distributing Chromium's C++ Toolchain
Author
Hans Wennborg, hans@chromium.org, Google
Distribution
Chromium's C++ toolchain, used to build Chromium and Chromium-derived web browsers.
Abstract (optional)
Chromium uses an LLVM-based C++ toolchain to build the browser for all its supported platforms. This talk covers how we build the toolchain for best performance, test it to be confident it works, and distribute it to all our developers and infrastructure. In particular, it covers how we manage to stay so close to the HEAD revision.
What's unique about the environment you package LLVM for? (optional)
What makes your distribution of LLVM unique? (optional)
Many host and target platforms: Windows, Mac, Linux, Android, iOS, Fuchsia
Living at HEAD: rigorous CI, shipping a new toolchain semi-weekly, no local patches, your LLVM commit can be used to build tomorrow's shipping canary version of the browser
Not a general-purpose toolchain release: building Chromium is the supported use case
Lots of upstream contributions to support our needs: clang-cl, the new lld; and things which are possible when controlling the whole toolchain such as constructor type homing, global type hashing for PDBs, etc.
What might others learn from your experience? (optional)
What could be improved in upstream LLVM to make working with it easier as a downstream packager? (optional)
Anything that makes the HEAD revision more stable.
Reminder that this is meant to be a 15 minute lightning talk; enough to pique interests but follow up should be done after. Slides can always include links to more info; we will ask that you send a PR to this repo with your slides when they are ready.
