- Move expression evaluation to ddc in preparation for google3
- Added server to ddc to handle update and compileExpression requests
- Added tests
- Added 'experimental-output-compiled-kernel' option to ddc to generate
full kernel files only for compiled libraries, and store with
'.full.dill' extension
- Added AssetFileSystem to communicate to the asset server in the
debugger
- Made expression_compiler_worker work with full kernel files,
so removed invalidation of current file to improve performance
- Made expression_compiler_worker reuse already loaded imports
to avoid reading them from source in the incremental compiler
- Updated tests to work with DDC (for simulating webdev)
- Disabled tests that work with bazel kernel worker for now
as it does not generate full dill files yet
- Addressed code review comments from the prototype version:
https://dart-review.googlesource.com/c/sdk/+/157005
Details:
Currently, in flutter tools, expression evaluation is supported via
expression compilation, which is done by the incremental compiler in
the frontend server. The same incremental compiler is used for initial
application compilation, incremental code compilation for hot reload,
and any number of expression compilation requests.
In google3, the apps are typically too large to be compiled as a whole
in memory by the frontend server. Build in google3 is currently done by
blaze, as a distributed build using a task dependency graph. Build tasks
output kernel outline files as an interface between components produced
by individual tasks.
We are proposing an implementation of the expression compilation in
google3 that is taking advantage of full kernel files produced by the
build (supporting build changes to follow). This change introduces a
small server based on dev_compiler, which can handle following requests:
- update: load full kernel for given modules (done on app start)
- compileExpression: compile expression in a given library and module
(done when paused on a breakpoint)
Expression compilation uses previously loaded kernel files for the
application component and its dependencies to compile an expression.

This adds support lowering the encoding of top-level/static fields
with initializers as if they were marked as late fields. This ensures
that LateInitialization is thrown if final fields are written to during

Fixes the case where libraries got renamed when created and
they are exported. Previously ddc was emitting broken code that
incorrectly used the original name in the export.
This bug was breaking some benchmarks at runtime.

Some benchmarks are located in directories named with characters
that are invalid in js identifiers. To generate bootstrapping that
loads these modules import the module builder and use the same
naming method that ddc uses.
These names are directly tied to the version of ddc that produces
them. This solidifies the fact that we really can't rely on using
the ddb script to run ddc from a different commit/build.

All of the backends (dart2js, DDC, VM) were checking if the invocation
name was tagged with "set:" and appending "=" to the name if so.
Instead, we can simply have the CFE perform this logic at the callsite.
Note that the name of the setter itself is still unchanged. Backends may
still need to generate the correct name themselves when handling NSMs
via code paths other than instantiateInvocation.

Now that the sound null safety mode is a compile time flag
instead of a runtime flag there is no need to set the value in
the bootstrapping code before running main(). The sound and weak
versions of the sdk now have it already set.
Add compileTimeFlag() method that will inline the constant value
directly into the generated output.

This is the first step to removing all of the the sdks precompiled
to JS modules from the sdk download.
Enables build_runner to produce a JS file on demand from a .dill
file bundled in the sdk download. At this time, only the SDK can
be compiled from a .dill file.
Update build targets to run bin/dartdevc.dart instead of
tool/compile_dartdevc_sdk.dart.
Will delete tool/compile_dartdevc_sdk.dart after we cleanup all
of the uses outside of the SDK.
