* Avoid calling memmove(dst, nullptr, 0) as this is flagged by UBSAN.
* Avoid hitting a bug[1] in the linker: LLD's identical code folding
(ICF) happens to replace RecordCoverageInstr::DebugName() with
DispatchTable::LargestSmallOffset() because they happen to contain
the same machine code, ICF fails to accomodate that DebugName also
contains a relocation to constant string. To avoid this we simply
eliminate LargestSmallOffset and replace it with a constant. Same for
OriginElement.

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).
