[vm] Make heap snapshot writer also visit isolate stacks as roots Heap snapshots currently produced don't visit isolate stacks. As such analyzing such snapshots may lead one to conclude there is a lot of garbage while objects are actually reachable. => This CL makes us visit isolate stacks when building heap snapshots. Furthermore we add a new `VMInternals.writeHeapSnapshotToFile` helper that can be used to programmatically write snapshots and can be handy for internal use at times. (We also use this helper in a test) TEST=vm/dart{,_2}/heap_snapshot_test Change-Id: I976544b7f6d20863764af9a40bf1ffb3c319bbce Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/253785 Reviewed-by: Ryan Macnak <rmacnak@google.com> Commit-Queue: 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.
