Revert "[vm] Refactor StubCodeCompiler to be a real class." This reverts commit afdf640866b1d702845b2b4da35a159db07cfbe6. Reason for revert: breaks google3. See b/274712076. Original change's description: > [vm] Refactor StubCodeCompiler to be a real class. > > Previously, StubCodeCompiler was just a set of static methods, all of > which take an assembler as their first arg. This makes it hard to pass > additional state to the ~160 stub macro defined stub generators. > > This refactor makes StubCodeCompiler a real class, with assembler as a > field. So we can easily add new fields to the class later, to pass new > state without having to update every stub generator. > > assembler is declared as a public field for a few reasons: > - There's one place where it needs to be accessed by a non-member > function (in the ia32 file). > - If it's private, it has to be named assembler_, which would mean a lot > more insignificant diffs. > - Non-member functions that take assembler would have to take assembler_, > for consistency with the __ macro, which would be weird. > > Change-Id: I142f0803a07c7839753188065c69c334d4d1798a > TEST=CI > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/289924 > Reviewed-by: Ryan Macnak <rmacnak@google.com> > Commit-Queue: Liam Appelbe <liama@google.com> Change-Id: If36a9122e1a55d86673d05afbbd21dfb27d7acd5 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/290522 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Ivan Inozemtsev <iinozemtsev@google.com> Reviewed-by: Alexander Thomas <athom@google.com> Commit-Queue: Emmanuel Pellereau <emmanuelp@google.com> https://dart.googlesource.com/sdk/+/7acb6f2c5c6ba2c04c1145bdff72dcb66fd346fb
Monorepo is:
With depot_tools installed and on your path, create a directory for your monorepo checkout and run these commands to create a gclient solution in that directory:
mkdir monorepo cd monorepo gclient config --unmanaged https://dart.googlesource.com/monorepo gclient sync -D
This gives you a checkout in the monorepo directory that contains:
monorepo/ DEPS - the DEPS used for this gclient checkout commits.json - the pinned commits for Dart, flutter/engine, and flutter/flutter tools/ - scripts used to create monorepo DEPS engine/src/ - the flutter/buildroot repo flutter/ - the flutter/engine repo out/ - the build directory, where Flutter engine builds are created third_party/ - Flutter dependencies checked out by DEPS dart/ - the Dart SDK checkout. third_party - Dart dependencies, also used by Flutter flutter/ - the flutter/flutter repo
Flutter's instructions for building the engine are at Compiling the engine
They can be followed closely, with a few changes:
goma_ctl ensure_start is sufficient.Example build commands that work on linux:
MONOREPO_PATH=$PWD if [[ ! $PATH =~ (^|:)$MONOREPO_PATH/flutter/bin(:|$) ]]; then PATH=$MONOREPO_PATH/flutter/bin:$PATH fi export GOMA_DIR=$(dirname $(command -v gclient))/.cipd_bin goma_ctl ensure_start pushd engine/src flutter/tools/gn --goma --no-prebuilt-dart-sdk --unoptimized --full-dart-sdk autoninja -C out/host_debug_unopt popd
The Flutter commands used to build and run apps will use the locally built Flutter engine and Dart SDK, instead of the one downloaded by the Flutter tool, if the --local-engine option is provided.
For example, to build and run the Flutter spinning square sample on the web platform,
MONOREPO_PATH=$PWD cd flutter/examples/layers flutter --local-engine=host_debug_unopt \ -d chrome run widgets/spinning_square.dart cd $MONOREPO_PATH
To build for desktop, specify the desktop platform device in flutter run as -d macos or -d linux or -d windows. You may also need to run the command
flutter create --platforms=windows,macos,linux
on existing apps, such as sample apps. New apps created with flutter create already include these support files. Details of desktop support are at Desktop Support for Flutter
Tests in the Flutter source tree can be run with the flutter test command, run in the directory of a package containing tests. For example:
MONOREPO_PATH=$PWD cd flutter/packages/flutter flutter test --local-engine=host_debug_unopt cd $MONOREPO_PATH
Please file an issue or email the dart-engprod team with any problems with or questions about using monorepo.
We will update this documentation to address them.
flutter commands may download the engine and Dart SDK files for the configured channel, even though they will be using the local engine and its SDK.gclient sync needs to be run in an administrator session, because some installed dependencies create symlinks.
