We are temporarily building a smaller SDK platform to make progress building applications against the forked sdk_nnbd sources. This is because some of the libraries have not yet been ported and they don't compose well. I needed to thread the status of the non-nullable experiment through the front end entry point and into the target options, and native types. Also includes some standardization of the flag name in DDC. https://github.com/dart-lang/sdk/issues/39698 Change-Id: I4bdd503be694b28d7f95828d4af28d1d5fb3691f Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/127486 Commit-Queue: Nicholas Shahan <nshahan@google.com> Reviewed-by: Sigmund Cherem <sigmund@google.com> Reviewed-by: Johnni Winther <johnniwinther@google.com>
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.
