Missing from this implementation: - Closure/dynamic calls with differing signatures - Overrides with extra optional parameters - Records with same shape defined in different dynamic modules - Avoiding running TFA on dynamic module. - Recompilation of only updateable functions from main module. - Persist wasm def types from main module. Testing is currently done locally via the dynamic_modules package test suite: dart pkg/dynamic_modules/test/runner/main.dart --runtime=dart2wasm Immediately after this lands we can introduce a new step to one of the wasm test matrix configurations that runs the above test suite (the VM has a similar configuration). Change-Id: I3386d84be11b773842d45f4268a62a54c47e352b Tested: Tested via new tests in dynamic_modules package. Tests run locally but will add to existing config.

Dart Kernel
Dart Kernel is a small high-level language derived from Dart. It is designed for use as an intermediate format for whole-program analysis and transformations, and to be consumed by codegen and execution backends.
The kernel language has an in-memory representation in Dart and can be serialized as binary or text.
Both the kernel language and its implementations are unstable and are under development.
This package contains the Dart part of the implementation and contains:
- A transformable IR for the kernel language
- Serialization of kernel code
Note: The APIs in this package are in an early state; developers should be careful about depending on this package. In particular, there is no semver contract for release versions of this package. Please depend directly on individual versions.
See ast.dart for the in-memory IR, or binary.md for a description of the binary format. For now, the textual format is very ad-hoc and cannot be parsed back in.
