Original change's description:
> [ios][build] Build application extensions in a separate toolchain
>
> Add new toolchains to build application extension (widgets, ...)
> and configure the different extensions to use it. This allow to
> disable PA for the extensions and will eventually allow passing
> `-fapplication-extension` to catch at compile time usage of API
> not available in application extensions.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
