The only actual change required to the profiler service is appropriately retrieving the source position for interpreted frames during processing. Otherwise, most of the tests just need small changes to account for the slightly different stack trace generated by interpreted code when walking the stack as code instead of functions: * Interpreted code calls the runtime entry DRT_AllocateObject directly for slow-path allocation instead of via the AllocateObjectSlow stub. * The current name for bytecode frames when walked as code starts with "[Bytecode]" instead of "[Unoptimized]". The test vm/cc/Profiler_GetSourceReport is skipped since: * It tests compiled code-specific features like classifying source positions. * Inserting fake samples for interpreted functions is messier since many PC offsets may map to the same source position. The other skipped tests are specific to inlining and/or optimized compiled code, so there's no point in running them on interpreted code.

Dart
An approachable, portable, and productive language for high-quality apps on any platform
Dart is:
-
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
-
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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).
