This was generated by replacing " NOTREACHED()" with " NOTREACHED_IN_MIGRATION()" and running git cl format. This prepares for making NOTREACHED() [[noreturn]] alongside NotReachedIsFatal migration of existing inventory. Bug: chromium:40580068 Change-Id: Idb68e2fc8adba180350b0595fd494cf0f206bded Reviewed-on: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/5548246 Reviewed-by: Mark Mentovai <mark@chromium.org> Commit-Queue: Peter Boström <pbos@chromium.org>
