    Message : Enable Chromium clang style plugin for libANGLE. This fixes a few style warnings: * auto should not deduce to raw pointer type * inlined virtual methods are not allowed * non-trivial constructors and destructors should be explicit * inlined non-trivial constructors should not be in-class * missing override keywords Bug: angleproject:3069 Change-Id: I3b3e55683691da3ebf6da06a5d3c729c71b6ee53 Reviewed-on: https://chromium-review.googlesource.com/c/1407640 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Yuly Novikov <ynovikov@chromium.org>
