- Adds JSVisitor that is used for unified heap marking. - Adds JSMember as supported reference type that also encapsulates a write barrier in future. JSMember is a replacement for TracedReference which can be deprecated with EmbedderHeapTracer once the library is used to handle unified heap collections. The dispatch for v8::JSMember on cppgc::Visitor is provided through a specialization of TraceTrait.

Similar to the feedback vector, we cannot embed the native context as a constant in NCI code (it is trivially native-context-dependent). In NCI mode, load it from the current context. In default turbofan, we keep the HeapConstant.

Turbofan now has support for generating generic code in two variants, with and without feedback collection. Currently, feedback is collected only for some load and store operators (historical reasons). This CL enables feedback collection for (almost) all operators by default. The exception in the default TF configuration are call and construct variants (see also https://crrev.com/c/2276042). In NCI mode, all operators collect feedback. Regression have looked acceptable in our benchmarks so far. This is an experiment to see impact on real world. If successful, the non-collecting variants can be removed.

When marking the function for a deopt due a dependency change, we only print the information about the code object. This isn't very useful when looking at the output of --trace-deopt. This cl also adds SharedFunctionInfo which makes it easier to see which function got deoptimized. Also adds these events to the log file so they can be used in profview to print more accurate deoptimization information.

This moves marking write barrier related functions from Heap and IncrementalMarking into a separate class: MarkingBarrier. Additionally, a new WriteBarrier class is added at the heap API level that dispatches to MarkingBarrier. Future CLs will move slots recording in MarkingBarrier and apply the same refactoring to the generational barrier. An instance of MarkingBarrier will be added to each LocalHeap and enable it to emit a write barrier from a background thread.

Prior to this CL, the construct node layout was: {target, args..., new_target} The new layout is: {target, new_target, args..., feedback_vector} Having new_target at index 1 brings it closer to call node layout, which is now identical except that it has receiver at index 1. The new feedback vector input will be needed for NCI code. Affected node kinds are: - JSConstruct - JSConstructWithArrayLike - JSConstructWithSpread - JSConstructForwardVarargs (just the new_target position change) Bug: v8:8888 Change-Id: I4c68a0901d01e8862fd276c8a858799d5f4ff024 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2278475 Commit-Queue: Jakob Gruber <jgruber@chromium.org> Reviewed-by: -

ForInNext can get lowered to a low-level call to the ForInFilter builtin. We currently type low-level Call nodes simply as Any, leading to a CHECK failure when the verifier expects a primitive. This CL fixes the issue simply by manually setting the type as part of the lowering. An alternative would be to have the Call typing inspect its input similar to what the JSCall typing does. We can consider this if we hit the same issue in other cases.
