This reverts commit430c75b5fa. Reason for revert: We probably don't care about the dartkb breakages. Original change's description: > Revert "[VM] Remove unnecessary Closure.clone() from sync*." > > This reverts commitca94ad7112. > > Reason for revert: Appears to break dartkb. > > Original change's description: > > [VM] Remove unnecessary Closure.clone() from sync*. > > > > Instead, this CL wraps sync*'s sync_op in an additional function > > that captures local copies of the necessary closure state. > > Notably this state includes the parameters of the original sync* function > > as these also need to be cloned for each instance. > > > > > > Note: a large number of .expect files have a small number of changes > > due to the additional wrapper function, as well as some extra plumbing. > > > > Bug: https://github.com/dart-lang/sdk/issues/37753 > > Change-Id: If099dbfe9e5d62979626b852386fd0173fc76de5 > > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/136190 > > Commit-Queue: Clement Skau <cskau@google.com> > > Reviewed-by: Vyacheslav Egorov <vegorov@google.com> > > TBR=vegorov@google.com,cskau@google.com > > Change-Id: I89e517196f03622337f909f0fcecbdc77c9dda93 > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: https://github.com/dart-lang/sdk/issues/37753 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/144920 > Reviewed-by: Clement Skau <cskau@google.com> > Commit-Queue: Clement Skau <cskau@google.com> TBR=vegorov@google.com,cskau@google.com Change-Id: I78589c83cbb17151ca4ab8f811b4f18f252fb9c1 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: https://github.com/dart-lang/sdk/issues/37753 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/144921 Reviewed-by: Clement Skau <cskau@google.com> Commit-Queue: Clement Skau <cskau@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.
