Regis Crelier eae248cc41 [VM/compiler] Emit a throw NoSuchMethodError for bad arity rather than aborting compilation.
The bad arity maybe detected after an isolate reload or when using strong mode with a mix of opted in and opted out libraries.
The thrown NoSuchMethodError contains enough information to be useful, but does not mirror the complete invocation (e.g. arguments).

This CL does not fix https://github.com/dart-lang/sdk/issues/37517 where the target is missing after a reload (not just bad arity).

The VM implementation of NoSuchMethodError is cleaned up, but the deprecated constructor 'NoSuchMethodError(...)' is not yet removed, since it is still documented.

Martin Kustermann 8d1c4c555c [vm/concurrency] Add various tests for lightweight AOT isolates
To enable our tests to spawn a new isolate in a new group, this CL
adds a `{bool newIsolateGroup}` parameter to the internal
`Isolate._spawnFunction` native and moves that native to
`dart:_internal`, thereby allowing runtime/tests/vm/dart/* to access it.

It also adds various tests for lightweight AOT isolates, exercising
GC, communication, spawning, ...

Martin Kustermann c01f9fb8a9 [vm/concurrency] Make an isolate group use a custom ThreadPool with maximum size
Our TLAB sizes and maximum new space size constrain the number of
parallel mutator threads we can have. Having too many mutator threads
would cause constant races between threads to acquire TLABs.

In reality we should constrain the number of threads to be at most the
number of cores, since at most that many threads can run in parallel
(i.e. at the same time).

This CL extends the TreadPool implementation to be constrained by a
maximum size. Furthermore it makes each isolate group's have it's own
pool with constrained size and schedule all group member
mutator / message handler tasks on that pool.

This relands the following CLs

    [vm] Make VM support .dart_tool/package_config.json
    https://dart-review.googlesource.com/c/sdk/+/145462

    [vm] Make Isolate.resolveUri() work for both `.packages` and `dart_tool/package_config.json`

    [vm] - Fix hang when no package config or .packages exist
    https://dart-review.googlesource.com/c/sdk/+/145661

The only change (extra patchset) is to let VM prefer the old/legacy
".packages" format and only use the newer
".dart_tool/package_config.json" if we failed to find a ".packages".

Ryan Macnak 160046f44c [vm] Move CID predicates out of RawObject.
When using C++ value types to represent tagged pointers, we cannot use forward declarations for tagged pointers. This helps to break include cycles when attempting to keep IsXYZ predicates as tagged pointer member functions.

class_id.h also seems like a more natural place for these predicates, which were written before there was a class_id.h.

Original commit description:

Speed up is achieved by sharing most of the dart code, object store
and class table between isolates in single isolate group. So
instead of bootstrapping isolate from the snapshot, isolate is
initialized by setting pointers to existing data structures already
set up for first isolate, and only few isolate-specific structures (moved
to newly introducted isolate_object_store) are created.

To allow for safe cross-isolate switchable call site, type test cache
mutations additional synchronization via RunWithStoppedMutators(that
relies on safepoints) was added.
Besides switchable call sites, no other mutation to the dart code is
done in AOT, which allows such sharing.

Vyacheslav Egorov a41a1dc917 [vm/compiler] Split compiler sources out of normal VM sources.
Make them form its own source set (libdart_compiler) and completely exclude
them from AOT runtime targets.

Previously we had some inconsistencies, with some files were using
DART_PRECOMPILED_RUNTIME to fully or partially exclude either contents
from their headers or from implementation, while other files did nothing
and relied on linker to throw their contents away.

This change tries to address this inconsistency.

A follow up change would include a check in most compiler headers which
would prohibit to use them while building AOT runtime.

Victor Lima b951498903 [vm/aot] Allow static methods to have unboxed args and return
Static methods and constructors may receive unboxed parameters.
This change adds a bitmap to the RawFunction object indicating
which parameters are unboxed and their types. Also, the stack frame
bitmap was updated to include new bits for those parameters.

The ArgumentsDescriptor object was updated to store not only the number
of arguments, but also their size, since 32-bit platforms would use two
words for each int64 and double value.

In addition, static methods that return non-nullable integers
and doubles may return these values unboxed.

Daco Harkes 8408232522 [vm/ffi] Replace FFI compiler pipeline
Introduces NativeRepresentation and NativeLocation for the compilation of FFI.

NativeRepresentations are able to express all representations (or types) of the native ABIs we bind to with FFI, this is more representations that than that are used in Dart itself.
NativeLocations are able to express all locations of the native ABIs we bind to with FFI, this is more types of locations than that are used for the Dart calling convention.
See the documentation in the respective files.

These NativeLocations and NativeRepresentations are computed by the NativeCallingConvention and consumed by the Marshaller and Assemblers.

This reenginering is required for go/dart-ffi-by-value, hardfp (Arm S and D fpu registers), and iOS 64 bit (non-word-aligned stack arguments).

In addition, by using the NativeRepresentations we also get slightly reduced code size:

* The tracking of sizes is improved, so less sign/zero-extension operations are required.
* UnboxedWidthExtenderInstr is fully removed, the size extension is done inside the native moves, coalescing moves and size extension when possible.
* BitCastInstr is only used when really needed. This reduces code-size on arm32 softfp.

This fixes the iOS arm64 calling convention, manually tested with https://github.com/flutter/flutter/pull/46078 and https://dart-review.googlesource.com/c/sdk/+/131074.

nnbd semantics although run in weak mode.

- methods IsNullType, IsTopType, and IsNeverType are modified.

Ben Konyi 16e7647c86 [ VM / dart:typed_data ] Fixed issue where null could be passed for simd types in AOT
Arguments to simd type constructors were being checked in the bootstrap
natives entrypoint but not elsewhere. Checking for null in Dart code
ensures that we don't accidentally miss these checks in AOT.

The changes to sdk_nnbd are required in order to ensure the number of
arguments passed to native code match the number of arguments from the
non-NNBD implementation (we needed to remove the implicit type args
parameter).
