In case you're worried this is outdated, note this is for version 10 of gcc (pdf is a pre-release) as stated on the frontpage of the document. I am curious how they plan to keep this updated, I could not easily find the repository for this.

Manuals, for both users and developers, are part of the gcc source code repository.

GCC 10 is marked as "prerelease BETA" in my package manager, so I know that this PDF is up-to-date. I was looking to use it as a cheap way to keep track of new developments ;)
