Alexander Markov 2397862762 [vm/aot] Eliminate unnecessary try/catch and try/finally
This change adds an ability to replace

try {
  <body>
} catch (...) {
 throw;
}

and

try {
  <body>
} finally {
}

with <body> into unreachable code elimination kernel transformation,
which is used in AOT. These constructs can appear after assert code is
removed.

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).
