This removes redundant worklist draining in the fix-point iteration. It may discover more ephemerons and break the assertion. The draining is not needed because FinishConcurrentMarking ensures that all background threads drain their worklists.

These tests were disabled because scalar lowering wasn't fully implemented yet. Now we are at a stage when we can enable them. The only remaining tests with lowering test disabled are prototype instructions, once they are merged into the proposal proper, scalar lowering should be implemented for them, and relevant tests enabled.

Adds a cross-thread reference for strongly and weakly retaining objects on a thread other than the thread that owns the object. The intended use of the reference is by setting it up on the originating thread, holding the object alive from another thread, and ultimately accessing the object again on the originating thread. The reference has known caveats: - It's unsafe to use when the heap may terminate; - It's unsafe to transitively reach through the graph because of compaction; Change-Id: I84fbdde69a099eb54af5b93c34e2169915b17e64 Bug: chromium:1056170 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2436449 Commit-Queue: Michael Lippautz <mlippautz@chromium.org> Reviewed-by:

HandleBase::is_identical_to() is_identical_to in handle base is used to do the exact comparison by just comparing the locations. When the locations are different the values are compared. For Smis it compares 64 bits which might lead to incorrect behaviour. Smis loaded as a TaggedField has the root address added. It is expexted that we don't use higher order bits on Smi. Hence, is_identical_to shouldn't use these bits when comparing Smis. This cl fixes it by comparing the objects created from the given location. That takes care of correctly comparing the required bits.

The wrapper is only compiled if --experimental-wasm-typed-funcref is set. - Add CompileWasmToJSWrapper in wasm-compiler. - Rename BuildLoadFunctionDataFromExportedFunction -> BuildLoadFunctionDataFromJSFunction to reflect its wider usage. - Rename BuildWasmImportCallWrapper -> BuildWasmToJsWrapper to reflect this function is now also used by CompileWasmToJSWrapper (unrelated to imports). - (Drive-by) Remove dead arguments from wasm-module-builder.js.

Create a HandleScope when serializing an object's contents, to reduce the number of live handles during serialization. There's only a couple of cases where these handles have to outlive the serialized contents, and for these cases we introduce GlobalHandleVector or similar manual strong root mechanisms. In particular, backrefs don't actually need to exist as a handle vector (the object addresses are already referred to by the reference map's IdentityMap), except for DCHECKs, so this becomes a DEBUG-only global handle vector. To support this manual strong-rooting, the HotObjectList is split up into a strong-rooted find-only class in Serializer, and a Handle vector in Deserializer.
