[vm, isolates] Avoid three-way deadlock during isolate exit.

Running mutator
  holds safepoint operation scope starting old space GC
  waiting for old space tasks to reach 0

Concurrent marker
  holds old space tasks > 0
  waiting for isolates_list_ lock to interrupt for finalization

Exiting mutator
  holds isolates_list_ lock_ to unregister isolate
  waiting for safepoint to end TransitionVMToBlocked

Reorder isolate [un]registeration to not need safepoint transition to acquire the isolates_list_ lock.

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).
