Reland "[vm/compiler] Remove unnecessary type check from optimized switches" This is a reland of commit 43ce5487c1d72af27e9d8157e8d664dabcd7a9d7 In addition to removing type check, switch range checks are adjusted in order to avoid call to 'int.operator<=', which can be removed by tree shaker in AOT/product mode, causing NoSuchMethodError at runtime. Original change's description: > [vm/compiler] Remove unnecessary type check from optimized switches > > Switch optimization now relies on static type of the tested value, > so it is safe to omit the type check (with sound null safety) or > reduce it to a null check (without sound null safety). > > TEST=co19/LanguageFeatures/Patterns/Exhaustiveness/exhaustiveness_enum_A01_t01 > Fixes https://github.com/dart-lang/sdk/issues/52422 > > Change-Id: Ic93f4f212bee9ed3bfe5035f3c8d7535274c2f63 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/304102 > Commit-Queue: Alexander Markov <alexmarkov@google.com> > Reviewed-by: Alexander Aprelev <aam@google.com> TEST=co19/LanguageFeatures/Patterns/Exhaustiveness/exhaustiveness_enum_A01_t01 TEST=language/async/switch_test Change-Id: I70bf480bf376f946d66caa504120c8f85093ea8d Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/304322 Reviewed-by: Alexander Aprelev <aam@google.com> Commit-Queue: Alexander Markov <alexmarkov@google.com>
Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
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.
See LICENSE and PATENT_GRANT.

Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch).
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
