Tess Strickland 3f53d22d43 [vm/compiler] Create leaf runtime entry for memmove.
Instead of making a StaticCall to _TypedListBase.nativeSetRange
inside _memMoveN, make a CCall to the memmove leaf runtime entry.

Rename _TypedListBase._nativeSetRange to _setClampedRange, since
it's now only used when per-element clamping is necessary.

Fix the load optimizer so that loads of unboxed fields from freshly
allocated objects do not have the tagged null value forwarded
as their initial post-allocation value.

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).
