[vm/jit] Pessimize type assumption in LoadLocal of covariant parameter. This avoids unsound optimizations that could arise from loading a parameter before its type had been checked. Affects only unoptimized code. Fixes https://github.com/dart-lang/sdk/issues/43464 Some considerations for a cleaner fix are described in https://github.com/dart-lang/sdk/issues/43654 Change-Id: I05872e46495313e82e9c516e5f283e1bc4612300 Cq-Do-Not-Cancel-Tryjobs: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/164500 Commit-Queue: Aske Simon Christensen <askesc@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com>
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).
Dart is free and open source.
