Change-Id: I8a0943979d94df2e44abd48f1bf981b1a01f348a
Binary-Size: 27k bytes is just above the threshold, upstream will remove this flag soon and this gives us slightly faster compiles (size increase likely due to more ThinLTO function importing due to fewer instructions in functions)

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.
