Aske Simon Christensen 1ab705f60c [vm] Require all recognized methods to be marked with pragma.
Adds a @pragma("vm:recognized", <kind>) to all recognized methods, where
<kind> is one of "intrinsic", "graph" or "other", corresponding to the
kind of recognized method.

When running in debug mode, it is checked that all recognized methods
are marked with the correct kind of pragma, and that all methods marked
with the pragma are in fact recognized.

This enables kernel-level analyses and optimizations to query whether
a method is recognized by the VM.

TEST=Asserts that check the correspondence both ways, covered by test
suite, in particular the various CompileAll tests that compile all code.

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).
