Currently, serialized dump info metadata (output of emitter phase) contains all the impacts created during codegen in a Map<MemberEntity, WorldImpact>. These impacts are already serialized in the output of the codegen phase. This is bad for two reasons: 1) The serialized bytes are duplicated. 2) The impacts cannot be GCed right after the emitter uses them, the dump info registry maintains a reference to them. To mitigate this I've updated the registry to only store impacts for entities where the impacts are generated during the emitter phase (today only parameter stubs). Rather than try to re-generate those impacts during the dump info phase, we serialize them with the dump info metadata. However, most impacts are generated during the codegen phase and for these we deserialize them from the codegen results at the beginning of the dump info phase.

Dart
An approachable, portable, and productive language for high-quality apps on any platform
Dart is:
-
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
-
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
