Alexander Aprelev 65d0d8581a [vm/shared] Move forward_table from Isolate to Thread.
Having forwarding tables on the Thread allows for those tables to be used in dart mutator thread running in IsolateGroup-shared context. On 32-bit platforms(arm) the forwarding tables are used during [SendPort.send] message verification.

- Fix signature of DLRT_Enter/ExitSafepoint.
- Give non-leaf runtime functions C linkage, as C++ does not have a defined ABI.

Gabriel Terwesten 903eea6bfb [vm,dartdev] Support dynamic linking between libraries
The same bundling that is used for `dart build` is now also used for
`dart test` and `dart run`, except that the output directory is
`.dart_tool/native_assets`. This way all native code assets are placed
next to each other in the `lib` directory, and loaded from there
instead of loading them in place from where the build/link hooks
placed them. By standardizing on this layout the different modes of
running dart code that support native assets can use the same
mechanisms to support dynamic linking between libraries.

On macOS, install names of dylibs are rewritten to support dynamic
linking, similar to the changes in
https://github.com/flutter/flutter/pull/153054.

On Windows, loading of DLLs is altered so that the directory of the DLL
that is being loaded is considered when loading dependent DLLs.

Tests are added to verify that dynamic linking works as expected.

Tess Strickland 9b06e26620 Reland "[vm] Enforce that entry points must be annotated by default."
This is a reland of commit cb9ecbc363

This reland only turns on the entry point verification flag by

in JIT mode have been appropriately updated, a followup CL will
turn this flag on by default in JIT mode as well.

false for this argument now.

Add annotations as needed, such as annotating classes with
annotated generative constructors. In some cases, the annotations
were more general than needed (e.g., annotating with a no-argument
entry point annotation when only the setter is needed), so make
those annotations more specific.

As this pattern is already common in downstream code, allow
Dart_Invoke on fields as long as the field is annotated for getter
access. (That is, calling Dart_Invoke for a field is equivalent to
retrieving the closure value via Dart_GetField and then calling
Dart_InvokeClosure.)

Daco Harkes 9a6503b500 [vm/ffi] Add embedder API for resolving asset ids
Extends the `NativeAssetsApi` with a `dlopen` that takes an asset id
instead of an asset path. This enables the embedder (instead of the
vm) to resolve the asset id to asset path.

Additionally, the `NativeAssetsApi` gets an `available_assets`
callback to report which asset ids are available if asset resolution
failed. (Otherwise, users would lose this important part of the error
message on failed resolution.)

We postpone migrating the Dart standalone embedder to this API: https://dart-review.googlesource.com/c/sdk/+/388160. That CL verifies
this new API and it's implementation. Without that CL this new API is
hard to test. So, no further tests are added here.

Tests that verify the old behavior for the standalone embedder:

Alexander Markov ab19361e87 [vm] Masquerade VM internal types more consistently
VM has been hiding certain internal implementation types by

However, types of record fields were not converted,

This change fixes this bug by applying the same type conversion to

The simulator was patched to account for this
https://dart-review.googlesource.com/c/sdk/+/244320.

However, the runtime entry was not patched leading, to inconsistent

This CL ports the simulator fix to the runtime entry.

RISC-V, x64, and ia32 are untouched.

Alexander Markov b48008ebd0 [vm] Remove unused dart:math and Double native methods
Flow graph builder implementation of certain dart:math and Double
methods is now used unconditionally, so corresponding native
methods are never used and can be removed.

This is a follow-up to
https://dart-review.googlesource.com/c/sdk/+/371980.

Ryan Macnak 0713bce1fe [vm, gc] Check for pause requests when marking large arrays.
This was sometimes responsible for the largest GC pause in IsolateSendExitLatency, with a scavenge waiting for a concurrent marker to finish a whole array and pause.

Daco Harkes 9588927faf [vm] Native asset relative path resolution with symlinks
This CL moves native assets resolution to the embedder.

The Dart VM looks up the asset path (for example
`['relative', 'foo.so']`) with the asset id. The embedder defines
callbacks for asset loading, and returns a handle to the dylib.
Then the VM calls the embedder again with `dlsym` to lookup the symbol.

The Dart VM & kernel compiler are responsible for the asset id to
asset path mapping. The kernel compiler compiles it into the snapshot
and the VM looks it up in the snapshot.

Relative paths are resolved relative to the isolate script uri (kernel
snapshot, jit snapshot, aot snapshot, or `dart compile exe` result).
The embedder is responsible for remembering the script uri it set when
spawning the isolate group.

This CL does not add `dlclose` or `dladdr` embedder callbacks yet.

Daco Harkes 4b2906cdc1 [vm] Move ResolveUri to platform
This will enable the standalone embedder to resolve uris in a follow
up CL:
https://dart-review.googlesource.com/c/sdk/+/361881

The implementation was using zones for allocation, this CL switches
that to using `malloc`. The caller is responsible for freeing the
memory if resolving succeeds.

This CL removes `Dart_DefaultCanonicalizeUrl`.

We don't have a run_platform_tests, so this CL keeps the tests in
run_vm_tests.
