Add "Unsafe" suffix to those Class::Lookup* methods to indicate they will need program structure protection locking. This allows to localize program structure protection locking inside of those Resolver methods. Bug: https://github.com/dart-lang/sdk/issues/36097 Change-Id: Ie5b0a190f6d3256448f2e528fa8ee52421e1639a Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/167960 Commit-Queue: Alexander Aprelev <aam@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com>
