- Switch the kernel isolate to run in Dart2 mode - Refactor build rules so bootstrapping of the front end happens with a prebuilt dart sdk - Refactor application snapshot build rules so the kernel application snapshot rule does not get into a cyclic dependency during the bootstrap stage Change-Id: Id16b2859e0b299b2d689971d03a247cb94d0aa26 Reviewed-on: https://dart-review.googlesource.com/61660 Commit-Queue: Siva Annamalai <asiva@google.com> Reviewed-by: Zach Anderson <zra@google.com>
