  Hash : 1c7f08c3
  Message : Inline RefCountObject::release. Also don't return errors from the object release methods. Not returning errors reduces the amount of code generated. Also we shouldn't be exiting early from destructor type functions. Increases object binding performance. Bug: angleproject:2877 Change-Id: Ieb8120d885b946915e355419825e1f52f31d7b49 Reviewed-on: https://chromium-review.googlesource.com/c/1270218 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
