[dart2wasm] Make int, double, bool box fields immutable Make the `value` fields of `BoxedInt`, `BoxedDouble` and `BoxedBool` `final`, to generate immutable Wasm fields for them. Immutable fields can potentially generate better code, as loads from the same object will always generate the same value. To allow making the `value` fields `final`, add a constructor. To allow adding a constructor, "implement` base classes instead of extending them. With `extends` the front-end wants us to call the superclass constructors, even though they don't have any constructors. Implementing `bool` (instead of extending) causes issues in TFA as it currently assumes bool literals are compiled as the `bool` class. Update TFA to treat bool literals the same way as `int` and `double` literals. Tested: existing tests Change-Id: I3282e188d784fa7a22421edc79ed47f9d85faf19 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/393320 Commit-Queue: Ömer Ağacan <omersa@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com>
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).
Dart is free and open source.
