Revert "[build, vm] Access TLS with less code." This reverts commit aa79cf2708a309b281416076f316d8e2d9405667. Reason for revert: -fPIC is needed in more places than the CL adds it to, see CI builds at https://ci.chromium.org/ui/p/dart-internal/builders/ci/dart-sdk-linux-riscv64-dev/405/overview Original change's description: > [build, vm] Access TLS with less code. > > - Avoid TLS initialization checks by using inline initialization. > - Avoid global offset table indirection by reducing -fPIC to -fPIE. > > out/ReleaseXARM64/exe.stripped/dart_precompiled_runtime > 11137992 -> 11274776 (-1.21%) > > We still need -fPIC in some places because we build a few shared libraries for FFI, so copy some of Fuchsia's GN setup to use -fPIE or -fPIC as appropriate. > > TEST=ci > Change-Id: I6402fce3366a9c4b2741ffb4811562292b8ecb71 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/285704 > Commit-Queue: Ryan Macnak <rmacnak@google.com> > Reviewed-by: Daco Harkes <dacoharkes@google.com> Change-Id: Idacb7869e9fa9ad0f7ed7b0caa2bae19deece7d0 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/286144 Reviewed-by: Martin Kustermann <kustermann@google.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Auto-Submit: William Hesse <whesse@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.
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.
You can also contribute patches, as described in Contributing.
