Stephen Adams c9ebc7c13f [dart2js/kernel] Fix poor code with nested List.generate
Cloning of InstanceInvocation kernel ast nodes was dropping the
isInvariant and isBoundSafe flags, causing the nested List.generate
expansion to not be as well optimized. `-O3` and `-O4` were 'hiding'
the problem by removing the checks anyway.

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.
