Ryan Macnak 8f9113d9f1 [vm, gc] Try to handle virtual memory limitations on iOS.
iOS appears not to allow any single virtual memory allocation to exceed ~700MB.
iOS appears to limit the total amount of allocated virtual memory to amount of physical memory available, even virtual memory that is reserved by not committed.

So instead of trying to allocate the full 4GB region for compressed pointer, allocate the largest power-of-two that succeeds, and speculate that further allocations to into the same 4GB region.

Dart

A client-optimized language for fast apps on any platform

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).
