- Add resolver/call_test.cc for new unit tests, and move a couple that were in resolver/validation_test.cc to it - Fix CalculateArrayLength transform so that it passes the address of the u32 it creates to the internal function - Fix tests broken as a result of this change Bug: tint:664 Change-Id: If713f9828790cd51224d2392d42c01c0057cb652 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/53920 Reviewed-by: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
