[vm/compiler] Print retained functions when tracing precompiler. To get this information, enable --trace-precompiler. There are two version of the output: a human readable version and a JSON version (preceded by 'JSON for function decisions:') for easier tabulation. The JSON version is an array of objects, where the fields of the object are as follows: * name: a string, the function name * kind: a string, the function kind * retained: a boolean, whether the function was retained * reasons: an array of strings, reasons for retaining (only for retained objects) TEST=vm/dart{,_2}/use_trace_precompiler_flag_test.dart Cq-Include-Trybots: luci.dart.try:vm-kernel-precomp-linux-release-x64-try,vm-kernel-precomp-linux-product-x64-try,vm-kernel-precomp-nnbd-linux-release-x64-try Change-Id: I9b006a49e1410a832950a1bd29a0abaabe9431f9 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/190000 Commit-Queue: Tess Strickland <sstrickl@google.com> Reviewed-by: Alexander Markov <alexmarkov@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.
