[vm] Add builtin TSAN suppressions Sanitizers can pickup configuration and suppressions via special symbols in the binary (e.g. __*_default_suppressions and __*_default_options). We have a bunch of stale files in the buildroot which showed how to do it, but none of these were actually used by the build process. Update our BUILDCONFIG.gn to actually link this code into the binaries and clean it up leaving behind only one relevant suppression for TSAN. Additionally fix libplatform targets - libdart_platform_no_tsan was accidentally disabling TSAN for the whole libplatform by adding no_tsan_config into public_configs instead of extra_configs. This is needed to unblock landing https://dart-review.googlesource.com/c/sdk/+/444983 TEST=manually with the referenced CL to verify that suppressions work Cq-Include-Trybots: luci.dart.try:vm-tsan-linux-release-x64-try,vm-tsan-linux-release-arm64-try Change-Id: Id4e8a5b89c665cf5d89b18c4f5881ef31c3c9396 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/445941 Commit-Queue: Slava Egorov <vegorov@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com>
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).
Dart is free and open source.
