Stephen Adams 8c13fa841e [dart2js] Kernel transformer expansion for List.generate
Simple calls to `List.generate` are expanded into a list allocation
and a loop. This generates better code for several reasons:

 - There is no overhead for the function argument (closure allocation,
   closure type, closure class)

 - Global type inference is more precise since each List.generate list
   is tracked separately, and the assignments in the loop give better
   inference to the collection's element type.

To get precise element type inference, there are two new JSArray
constructors. Global type inference starts with the element type being
bottom for these elements, avoiding spurious nulls in the inferred
type.

Regis Crelier 9711b9a331 [VM/kernel] Remove obsolete workaround when reading dynamic bound from kernel.
If the bound is not specified, CFE will use Object* in an opted-out library or Object? in an opted-in library, and not dynamic as before.
This workaround is therefore not needed anymore, and actually harmful as shown in the regression tests.

Closes https://github.com/dart-lang/sdk/issues/44136
Add regression tests.

`Null` we use a special messages that doesn't state that
"'Null' is nullable". Cases where `Null` is part of the type or where
the expression of type `Null` is derived from a collection are not

Daco Harkes 6101e4653b [test/ffi] Add struct stack alignment test
A smoke test to exercise alignment of structs with various field types
to see how they are aligned on the stack. Only contains small structs
because most ABIs only pass structs less than 16 bytes on the stack.

Especially tests iOS64, where `AlignOf(struct{float32;float32;}) == 4`
but `AlignOf(struct{int32;int32;}) == 8` due to the special treatment
of homogenous floats in the arm64 ABI combined with iOS decision to not
align everything on the stack to at least word size.

Test tested on iOS64 through Flutter.

structs_by_value_tests_configuration.dart is the only non-generated
file.

The tests are tested in the dependent CL. Tests are ignored in status
file and are un-ignored in dependent CL.

Tests for https://github.com/dart-lang/sdk/issues/36730.

Stephen Adams e769817cdc [tests] Split corelib{,_2}/list_concurrent_modify_test
Splitting out a failing test to increase coverage of other tests.

It is not clear that `a.addAll(a)` should throw if `a` is empty.
`a` is not modified by the action.

dart2js/DDC do not detect this case and I'm reluctant to add a check
for the case where `a` is in fact not modified.

The VM test is very specific to an identical argument and cannot
detect the case for `a = Mylist([])`.

Another option to this proposal is to simply delete the `[]` case.

In general, I'd like to move more ConcurrentModificationError tests
into assert statements.

asiva 5c0e6ba974 [Tests] - Fix legacy tests that broke when non nullability was enabled by default
1. lib_2/isolate/issue_6610_test - the source is served from a http request, the autodetect code causes the code to be served multiple times leading to 'count' being incremented multiple times.

2. standalone_2/http_launch_test - source is served from http request and hence the CFE auto opt out does not work for the spawned isolate

3. standalone_2/io/named_pipe_script_test - serves the source using a named pipe and the autodetect code does multiple fetches of the source resulting in an error

4. standalone_2/io/test_extension_test - spawns processes from a directory that is not auto opted out by CFE

TESTS = Fixes existing legacy tests.

Liam Appelbe f25c50fdcb [wasm] Use wasm traps to handle exceptions
The Dart exception is converted to a string, stored in a trap which
is passed through wasm, then converted back to a Dart exception.

Module instantiation can also throw a trap, because it internally
invokes the initialization function, if the module defines one. So I'm
handling this too.

Also, update to the new version of the wasm C API, which replaces some
foo_t** with foo_vec_t*.

Mayank Patke a5afc3e974 [dart2js] Remove tests/dart2js/boolean_conversion_test.
The dart2js_2 version still exists.

Prior to null safety, it was legal to assign `null` to a `bool`, so
things like boolean operators and control flow constructs required
null checks on their inputs. `--omit-implicit-checks` removed these null
checks, so we had to specify what the behavior would be in these cases.
(In general, `null` was just treated as a falsey value, since that's
what happens in JS.)

With null safety, it is no longer legal to assign `null` to a
(non-nullable) `bool`, so the backend freely optimizes boolean
expressions under this assumption. It's possible to smuggle `null` in
via a cast to `dynamic` and an implicit downcast to `bool`. The downcast
ordinarily fails at runtime but can be removed with
`--omit-implicit-checks`. We do not want to specify the behavior in this
case. We do not guarantee the behavior under `--omit-implicit-checks` of
code which would have failed with checks enabled.

Maintaining the old behavior would likely require us to be pessimistic
about nullability and miss optimization opportunities.

Daco Harkes 957487b5da [test/ffi] Structs by value 1-byte aligned
The 3 and 7 byte tests in
https://dart-review.googlesource.com/c/sdk/+/168829
had their sizes rounded up to the next power of two due to alignment of
fields inside the structs.

In order to properly exercise behavior on win32, win64 and iOS, this CL
changes those structs to only have uint8 fields to prevent alignment
influencing the sizes.

Old tests are renamed to exercise the size rounding due to alignment.

This also swaps around the two 9byte structs to have consistent naming
with the new 3 and 7-byte tests.

structs_by_value_tests_confguration.dart is the only non-generated file.

Daco Harkes b62e715073 [test/ffi] Passing structs by value test generator
Split off from https://dart-review.googlesource.com/c/sdk/+/140290/33
to make that CL smaller and review the test generator separately.

Because of the amount of corner cases in the calling conventions that
need to be covered, the tests are generated, rather than hand-written.

The tests are tested in the dependent CL. Tests are ignored in status
file and are un-ignored in dependent CL.

Liam Appelbe e2840ed07a [wasm] Basic WASI support.
Enabling WASI when building an instance sets up the default WASI
imports, and can optionally capture stdout/stderr. I'd like to set up
something similar for stdin, but Wasmer doesn't support that yet.

I also improved error handling in WasmRuntime by adding Wasmer's last
error to the thrown exceptions where appropriate.

Lasse R.H. Nielsen a15025fc85 Harden StreamIterator against out-of-order events.
Users have seen event being sent *during* the `listen` call
to the underlying stream. This caught the `StreamIterator`
in an unanticipated state (subscription wasn't available yet).

Sending events during a `listen` call can currently happen
using a synchronous broadcast stream controller adding
events in the `onListen` callback.
That should be fixed so that broadcast stream subscriptions
are treated as paused during the `onListen` call like
single-subscription streams already are.

This change hardens the class against that particular malpratice,
but it's still possible to get into inconsistent states if the
`listen` call somehow manages to call back into the same
stream-iterator again. So, don't do that.

(The class also assumes that no stream will send events/call callbacks
* while paused.
* after cancelling
* after a done event
* while delivering another event.

If a stream does so, things will still crash.
It is believed that no platform stream will do any of these.)

Fixes #43779.
