Dart == calls now are rewritten to an Identical node (if applicable), which can then be specialized further into JS == and === nodes. Previously, == calls would specialize directly to JS == and === nodes, but some of these optimizations were then missed for the cases where Identical nodes are introduced directly (e.g. for switch cases). The rules have also changed a bit to be more effective, and there are some small improvements to the utility functions.

Run Existing Tests ================== See the output of ../tools/test.py --help for how to run tests. See also https://code.google.com/p/dart/wiki/Building#Testing for detailed examples. Create New Tests ================ See comments above factory StandardTestSuite.forDirectory in ../tools/testing/dart/test_suite.dart for the default test directory layout. By default test-file names must end in "_test.dart", but some test suites, such as ./co19, subclass StandardTestSuite and override this default. See comments at the beginning of ../tools/testing/dart/multitest.dart for how to create tests that pass by failing with a known error. For example, ... int x = "not an int"; /// 01: static type warning ... as part of a test will only pass the "--compiler dartanalyzer" test if the assignment generates a static type warning.
