Daco Harkes f992bfc7b1 Revert "[vm/ffi] Introduce `Struct.create` and `Union.create`" This reverts commit `c2e15cff6d`. Reason for revert: https://github.com/dart-lang/sdk/issues/54754 Version skew somewhere in the analyzer/dartdoc/flutter combination. We need to land the fix inside ffi_verifier.dart first, and then reland the API docs that trigger the code path in the analyzer that throws the exception. Original change's description: > [vm/ffi] Introduce `Struct.create` and `Union.create` > > Structs and unions can now be created from an existing typed data > with the new `create` methods. > > The typed data argument to these `create` methods is optional. If > the typed data argument is omitted, a new typed data of the right > size will be allocated. > > Compound field reads and writes are unchecked. (These are > TypedDataBase loads and stores, rather than TypedData loads and stores. > And Pointers have no byte length.) Therefore the `create` method taking > existing TypedData objects check whether the length in bytes it at > least the size of the compound. > > TEST=pkg/analyzer/test/src/diagnostics/creation_of_struct_or_union_test.dart > TEST=pkg/vm/testcases/transformations/ffi/struct_typed_data.dart > TEST=tests/ffi/structs_typed_data_test.dart > TEST=tests/ffi/vmspecific_static_checks_test.dart > > Closes: https://github.com/dart-lang/sdk/issues/45697 > Closes: https://github.com/dart-lang/sdk/issues/53418 > > Change-Id: If12c56106c7ca56611bccfacbc1c680c2d4ce407 > CoreLibraryReviewExempt: FFI is a VM and WASM only feature. > Cq-Include-Trybots: luci.dart.try:vm-aot-android-release-arm64c-try,vm-aot-android-release-arm_x64-try,vm-aot-linux-debug-x64-try,vm-aot-linux-debug-x64c-try,vm-aot-mac-release-arm64-try,vm-aot-mac-release-x64-try,vm-aot-obfuscate-linux-release-x64-try,vm-aot-optimization-level-linux-release-x64-try,vm-aot-win-debug-arm64-try,vm-aot-win-debug-x64c-try,vm-aot-win-release-x64-try,vm-appjit-linux-debug-x64-try,vm-asan-linux-release-x64-try,vm-checked-mac-release-arm64-try,vm-eager-optimization-linux-release-ia32-try,vm-eager-optimization-linux-release-x64-try,vm-ffi-android-debug-arm-try,vm-ffi-android-debug-arm64c-try,vm-ffi-qemu-linux-release-arm-try,vm-ffi-qemu-linux-release-riscv64-try,vm-fuchsia-release-x64-try,vm-kernel-linux-debug-x64-try,vm-kernel-precomp-linux-release-x64-try,vm-linux-debug-ia32-try,vm-linux-debug-x64-try,vm-linux-debug-x64c-try,vm-mac-debug-arm64-try,vm-mac-debug-x64-try,vm-msan-linux-release-x64-try,vm-reload-linux-debug-x64-try,vm-reload-rollback-linux-debug-x64-try,vm-ubsan-linux-release-x64-try,vm-win-debug-arm64-try,vm-win-debug-x64-try,vm-win-debug-x64c-try,vm-win-release-ia32-try > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/342763 > Commit-Queue: Daco Harkes <dacoharkes@google.com> > Reviewed-by: Johnni Winther <johnniwinther@google.com> > Reviewed-by: Lasse Nielsen <lrn@google.com> > Reviewed-by: Martin Kustermann <kustermann@google.com> Change-Id: I285dc39946b5659219b37a1d8f10de479133957e Cq-Include-Trybots: luci.dart.try:vm-aot-android-release-arm64c-try,vm-aot-android-release-arm_x64-try,vm-aot-linux-debug-x64-try,vm-aot-linux-debug-x64c-try,vm-aot-mac-release-arm64-try,vm-aot-mac-release-x64-try,vm-aot-obfuscate-linux-release-x64-try,vm-aot-optimization-level-linux-release-x64-try,vm-aot-win-debug-arm64-try,vm-aot-win-debug-x64c-try,vm-aot-win-release-x64-try,vm-appjit-linux-debug-x64-try,vm-asan-linux-release-x64-try,vm-checked-mac-release-arm64-try,vm-eager-optimization-linux-release-ia32-try,vm-eager-optimization-linux-release-x64-try,vm-ffi-android-debug-arm-try,vm-ffi-android-debug-arm64c-try,vm-ffi-qemu-linux-release-arm-try,vm-ffi-qemu-linux-release-riscv64-try,vm-fuchsia-release-x64-try,vm-kernel-linux-debug-x64-try,vm-kernel-precomp-linux-release-x64-try,vm-linux-debug-ia32-try,vm-linux-debug-x64-try,vm-linux-debug-x64c-try,vm-mac-debug-arm64-try,vm-mac-debug-x64-try,vm-msan-linux-release-x64-try,vm-reload-linux-debug-x64-try,vm-reload-rollback-linux-debug-x64-try,vm-ubsan-linux-release-x64-try,vm-win-debug-arm64-try,vm-win-debug-x64-try,vm-win-debug-x64c-try,vm-win-release-ia32-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/349061 Commit-Queue: Daco Harkes <dacoharkes@google.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Zach Anderson <zra@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com>		2024-01-30 10:43:22 +00:00

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).

License & patents

Dart is free and open source.
