  Hash : a9f11bf1
  Message : GN: Separate out constructor/destructor warnings. This will allow for the capture/replay sample to disable the warnings. We'd like to keep them enabled for most of ANGLE code. Bug: angleproject:3611 Change-Id: I3cc7af26fa54c03cc5b79727e7b403a1b218a903 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1869544 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tobin Ehlis <tobine@google.com> Reviewed-by: Cody Northrop <cnorthrop@google.com>
