Reland "[vm/compiler] Unify methods for UnboxIntegerOpInstr subclasses." This is a reland of commit baa18e6d2933484d7acdc4e781a062f91bed63c2 Fixes IsRepresentable to take a int64_t, not a uint64_t. Original change's description: > [vm/compiler] Unify methods for UnboxIntegerOpInstr subclasses. > > Unify the Canonicalize() methods on subclasses of UnboxIntegerOp > so that there aren't subtle differences between canonicalizing > UnboxInt32 and UnboxUint32 instructions. Also unify the > ComputeCanDeoptimize() methods for similar reasons. > > If canonicalizing a truncating unbox of a constant, then create an > unboxed constant of the truncated value instead of an unboxed > constant of the original untruncated value. > > Previously, a subclass of Definition that didn't override InferRange > got a default range solely based on its type. Now, if the representation > of the definition is an unboxed integer, the default range is the > intersection of the range inferred from its type with the range > inferred from its representation. > > TEST=ci > > Change-Id: Ib022c366904ee6f8a81995bd4c16b87bd876176d > Cq-Include-Trybots: luci.dart.try:vm-aot-linux-debug-simarm_x64-try,vm-aot-linux-release-x64-try,vm-aot-linux-debug-x64-try,vm-aot-linux-debug-x64c-try,vm-win-release-x64-try,vm-ffi-qemu-linux-release-arm-try,vm-ffi-android-debug-arm-try > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/332400 > Reviewed-by: Slava Egorov <vegorov@google.com> TEST=ci (including simarm, not just simarm_x64) Change-Id: I6f3d3976634da9725d1a81faa62ab9b718d6663e Cq-Include-Trybots: luci.dart.try:vm-aot-linux-debug-simarm_x64-try,vm-aot-linux-release-x64-try,vm-aot-linux-debug-x64-try,vm-aot-linux-debug-x64c-try,vm-win-release-x64-try,vm-ffi-qemu-linux-release-arm-try,vm-ffi-android-debug-arm-try,vm-linux-release-simarm-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/333001 Reviewed-by: Slava Egorov <vegorov@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.
See LICENSE and PATENT_GRANT.

Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch).
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
There are more documents on our wiki.
The easiest way to contribute to Dart is to file issues.
