Jens Johansen b21e12aebf [CFE/kernel] Dummy TreeNodes can leak - null parent pointer in test 
As kernel `TreeNode`s have `parent`-pointers we can leak through our
dummy nodes. This CL makes a list of all TreeNode dummys so it's
possible to iterate over them and null out the parent pointer,
making it possible to plug the leak "on demand".
This doesn't feel like a real solution and for now is only used in a
test so those leaks doesn't obscure other leaks should any such surface.

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.
