Reland "[vm/ffi] Add class modifiers" This is a reland of commit 1755f8909264330a207a0e0e44d31f5fec9c489a Can land after (or with) the Flutter PR: https://github.com/flutter/engine/pull/40434 Original change's description: > [vm/ffi] Add class modifiers > > Adds class modifiers to `dart:ffi`. > > Migrates all user-defined subclasses of `Struct`, `Union`, `Opaque`, > and `AbiSpecificInteger` to be `final class`es. > > Does not remove the manual error checking, so some errors will show up > twice now in language version 3.0. In language version <3.0, only the > FFI-specific error will show up. > > In a follow-up CL, we will try to make the language-errors to show up > also <3.0 so that we can remove the FFI-specific errors. > > Examples of duplicated errors: > pkg/analyzer/test/src/diagnostics/subtype_of_ffi_class_test.dart > > TEST=pkg/analyzer/test/ (for the analyzer) > TEST=pkg/front_end/testcases/ (for the CFE) > TEST=test/ffi/ (for the VM) > > CoreLibraryReviewExempt: No need for dart2js to review. > Bug: https://github.com/dart-lang/sdk/issues/51683 > Change-Id: I2964ceccb7db59fbdaf6be5319f5e4ec2dabe0f3 > Cq-Include-Trybots: luci.dart.try:pkg-linux-debug-try,pkg-win-release-try,pkg-mac-release-try,vm-precomp-ffi-qemu-linux-release-riscv64-try,vm-precomp-ffi-qemu-linux-release-arm-try,vm-ffi-android-debug-arm64c-try,vm-ffi-android-debug-arm-try,vm-reload-rollback-linux-debug-x64-try,analyzer-analysis-server-linux-try,analyzer-linux-release-try > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/289223 > Reviewed-by: Johnni Winther <johnniwinther@google.com> > Reviewed-by: Devon Carew <devoncarew@google.com> > Reviewed-by: Brian Wilkerson <brianwilkerson@google.com> > Reviewed-by: Jackson Gardner <jacksongardner@google.com> > Reviewed-by: Lasse Nielsen <lrn@google.com> > Commit-Queue: Daco Harkes <dacoharkes@google.com> TEST=pkg/analyzer/test/ (for the analyzer) TEST=pkg/front_end/testcases/ (for the CFE) TEST=test/ffi/ (for the VM) CoreLibraryReviewExempt: No need for dart2js to review.
