This adds basic infrastructure for a stringref implementation in
dart2wasm:
- A `--[no-]stringref` option to the compiler
- An option in the `WasmTarget`, controlling the name of the target
- Separate sets of patch files for the two targets
- Separate platform dill files for the two targets
For now, the patch file contents are the same, and the compiler flag
is not used by the backend (only by the `dart2wasm` script to select
the appropriate platform dill file). Both of these will change as the
implementation progresses.
Tested: ci + manual check that the option selects the correct dill

Use JS `setTimeout` for events and `queueMicrotask` for micro-tasks.
dart2js event loop implementation is copied in `run_wasm.js` to be able

`scheduleMicrotask`, which are not not available in d8, and `setTimeout`

Determines the ultimate representation type of an inline class to
determine if it can use external members. This allows users to
elide @JS if they don't need renaming. This CL adds some static
errors around inline interop members so its clearer that the
inline class should have an interop representation type.
There's a bit of cleanup in this CL too around interop members,
where extension members on @Native classes are now correctly
considered as interop members by the error checker.

Currently setting exception variables in `catch` blocks assumes that the
variables are not captured and always creates a new local for the

This CL adds a new function for initializing a variables. The

This annotation is unneeded as named arg external constructors
is enough to determine if an object literal is created. The one
exception is an empty object literal, but our guidance is to use
utility functions to create one instead. This is a better fit for
that purpose too as an interface for an empty object literal is
more uncommon.

This was originally implemented in a289c4d but then reverted in dc33261
as it broke Flutter: https://github.com/flutter/flutter/issues/124282.
The problematic code in Flutter was updated, so landing the fix again.
Original commit message:
`emitTypeTest` optimizes a test like `x is List<T>` where `x :
Iterable<T>`, i.e. tested-against type is a subtype of the operand's
static type. In these cases we can check just the class ID of the
operand without checking the type arguments.
However this optimization cannot be done when the types don't have same
number of type arguments. Example:
class H1<T> {}
bool test(Object o) {
return o is H1<num>;
}
void main() {
print(test(H1<Object>()));
}
Here `H1<num> <: Object`, but we still need to check the type parameter.
This CL checks that the types have the same number of type arguments
before optimizing the test.
Fixes#51187.
This fix reveals another bug in `static_interop_test`, which is tracked
in #51200. The test is updated to work around the bug for now.

`Completer<bool>` value for the suspension or a user-emitted value as
the `async*` function can also yield `Completer<bool>` values. Update
the test from `value is Completer<bool>` to `!isEven`.

Does the following refactoring:
- Pares down visitor functions and moves larger blocks of logic into
helper functions
- Adds local functions for reporting to reduce the size of code that
reports diagnostics (all the 'report' functions)
- Organizes helper functions based on node type
- Adds static const variables for literals
- Marks variables that can be final as final
- Fixes/adds documentation for helper functions
There are some possible additional cleanups, like moving helper
functions to extensions and separating out state to mixins, but that
isn't necessary for now.

This CL re-implements the async function compilation without using JSPI
or any other platform features.
This implementation is faster than the JSPI-based one in all benchmarks,
in some cases up to 200x (benchmark results at the end). So we remove
the JSPI-based implementation as there's no point in maintaining a much
slower implementation and supporting two implementations at the same
time (which is tricky because these implementations need different
libraries, all scripts need to support two modes etc.) that also
requires experimental platform features.
# Main changes
- A new pass `AwaitTransformer` transforms `await` expressions to
top-level statements in form `var <fresh variable> = await <simple
expr>`, where `<simple expr>` is an expression without `await`.
After this pass all `await` expressions have the simple continuation
of "assign the value of the awaited future to this variable and
continue with the next statement". This simplifies `await`
compilation.
- A new code generator `AsyncCodeGenerator` (inherits from
`CodeGenerator`) compiles `async` functions. The `_YieldFinder` class
is copied from `sync*` code generator but modified to handle `async`
expressions.
- Mentions to the V8 flag `--experimental-wasm-stack-switching` is
removed from all scripts and documents.
# Future work
- Control flow handling in `AsyncCodeGenerator` needs to be implemented
in a similar way in `SyncStarCodeGenerator`. Doing this without
duplicating a lot of code will require some refactoring.

The map `breakFinalizers` need to have insertion-ordered iteration
otherwise creation of Wasm blocks when compiling try-finally blocks
won't work. Update the map type from `Map` to `LinkedHashMap` to make
this clear.
This doesn't change the concrete map type used as non-constant map
literals are already compiled to `LinkedHashMap`s, just makes the type
more precise for clarity.

Currently the `InstanceGet` node result type for for

This causes problems in CL 301020 where we generate temporaries for
nested `await` expressions and use the expression type for the types of
those temporaries. Incorrect expression type in `completer.future`
causes a temporary with incorrect type to be generated.

Currently, dart:_js_types types are all typedefs in the web backends.
This leads to inconsistent semantics, since you can statically pass
Strings to JSString, for example. You cannot do this in dart2wasm.
In order to ensure consistent semantics, we reify these types using
a custom @staticInterop lowering. They all get erased to their
respective Dart type. When we have inline classes, these types
should be implemented using inline classes.
Note that Interceptor will not work for this use case. The reified
type of JS primitives are Dart types e.g. String, bool, and therefore
can not be casted to Interceptor.
In order to do this, the eraser is refactored and the JS backends use
shared erasure code to either erase/emit types.
Tests are added to make sure you need to go through a conversion or
cast to pass Dart objects to JS types.

Currently when `switch` expression is nullable (so the values are boxed)
we currently use `ref.eq` to compare the values.
This doesn't work as expected when one of the values is a constant and
the other one is a runtime-allocated value. Example:
void test(bool? x) {
switch (x) {
case false:
print('no');
case true:
print('yes');
case null:
print('maybe');
}
}
bool runtimeTrue = int.parse('1') == 1;
void main() {
test(runtimeTrue);
}
Here the return value of `runtimeTrue` is boxed in the call site of
`test`. In the body of `test` we use globals for constants `true` and
`false`, which are never equal to runtime-allocated values.
We now use `identical` in these cases, which handles `bool`, `String`,
and `num` values as expected and compares the rest using `ref.eq`.

With https://dart-review.googlesource.com/c/sdk/+/289224 the front-end
can now generate switch-case expressions where type of the `switch`
expression is different than the types of expressions in `case`s.
To handle this case we have two options:
1. Compare type of `switch` and `case`s and compile the code to just
evaluate the switch expressions and the default case.
2. Use reference equality
This CL implements (2) as it's simpler and no correct code will have a
switch-case with differently typed switch and case expressions.
