So if the chromium repo is representative of the state of C++ in rest of Google, they ditched it silently like this probably because it's so natural to them :)
> <> means system headers and "" means project headers (my naive understanding of the difference)
they just convert everything to a project header? That seems bonkers to me. It is intentionally removing useful information.
They also are not removing any info -- most of it IS project headers. To me that's the actual bonkers bit :)
With GCC/Clang, headers found in paths passed with -isystem are headers that are immune to compiler arguments like -Werror because they are, by definition, out of your control. In Google's case, ALL code is already checked in the project repo, including language stdlib. So none of them are system headers "per se".
