The StackGuard in the sparkplug prologue builtin on x64 was called with the frame in a weird state; in particular, the baseline code PC wasn't on the stack. This could lead to oddities like the baseline code getting collected by a GC during the interrupt. Now we push the baseline code return address and set up a proper frame for the interrupt.

This is a reland of https://chromium-review.googlesource.com/c/v8/v8/+/2688058 This CL is part of a series that adds the C++ implementation of SwissNameDictionary, a deterministic property backing store based on Swiss Tables. This CL adds the initialization code, factory functions and a canonical SwissNameDictionary plus all helpers required for that.

We can use UseScratchRegisterScope instead of requiring a TempSimd128Register in the instruction-selector. This reduces register pressure a little bit (when combined with unique register constraints). Drive-by cleanup of some variable names in code-generator, s/tmp2/tmp/ when there is only 1 tmp.

My recent change https://crrev.com/c/v8/v8/+/2698057 changed the size of bytecode for most functions, and attempted to update other heuristic values to match. However, it caused V8 to be slightly too eager to perform on-stack replacement in JetStream 2's gaussian-blur test case, so that the function got compiled separately for each of two nested loops rather than just once for the outer loop. This is the smallest change that restores the previous behavior in that benchmark.

There are two aspects to the non-JSObject parts of JSArrayRef: - JSArrayRef::length. Relevant only in two spots, 1. when reading (immutable) array boilerplates and 2. for GetOwnCowElement. - JSArrayRef::GetOwnCowElement. May read into a copy-on-write backing store. Relies on the invariant that cow backing stores are immutable. This CL renames the length accessor to length_unsafe to make the danger explicit at callsites. For GetOwnCowElement the refactor is slightly larger, since we now need to read into the backing store while keeping full control of object reads (e.g. JSArray::length and JSArray::elements_kind). We make all reads explicit at the call site by requiring that elements, elements kind, and length are passed in as arguments to GetOwnCowElement. Inside GetOwnCowElement, consistency between these is *not* guaranteed due to concurrency. At runtime, consistency *is* guaranteed through the reference-equality check on the elements seen during compilation. The actual elements read is implemented in ConcurrentLookupIterator::GetOwnCowElement.

Process global accessors for total physical size and used size are needed for blink. These are implemented via an allocation observer that atomically updates static counters. The public api only provides getters for the counters. An internal class is in charge of updating the counters as needed. A similar split is also applied to IsAnyIncrementalOrConcurrentMarking(). Drive-by: ProcessHeap is merged into cppgc::internal::WriteBarrier.

IsMarking returns true as long as a marker exists. That means IsMarking is true during weak processing as well. ActiveScriptWrappableManager in blink uses a weak callback that updates a HeapVector and thus can trigger a write barrier during the atomic pause (which violates a DCHECK in the barrier).

ScopeInfo has a vestigial 'length' field from when it used to be a FixedArray. This change removes that field, which saves some memory. More specifically: - Make ScopeInfo inherit from HeapObject, not FixedArrayBase which supplied the 'length' field. - Privatize the FixedArray-style functions that provide access to ScopeInfo fields by index, and move them from scope-info-inl.h to scope-info.cc. Those functions are still used pretty heavily during initialization (ScopeInfo::Create, etc.), but at least we can avoid presenting them to the rest of the world. - Change FactoryBase::NewScopeInfo to allocate the updated object shape. It maintains the existing behavior of filling the newly-allocated object with undefined, even though that's not a valid ScopeInfo and further initialization is required. - Move part of AccessorAssembler::ScriptContextTableLookup into a new Torque macro, because it used to rely on casting ScopeInfo to FixedArrayBase. - In V8HeapExplorer::AddEntry, don't claim that ScopeInfo objects are arrays. I think it makes more sense to list them under "(system)" in the dev tools, like most other V8 internal types.

This CL is part of a series that adds the C++ implementation of SwissNameDictionary, a deterministic property backing store based on Swiss Tables. This CL adds the initialization code, factory functions and a canonical SwissNameDictionary plus all helpers required for that.

This is a reland of cf93071c Original change's description: > [interpreter] Short Star bytecode > > Design doc: > https://docs.google.com/document/d/1g_NExMT78II_KnIYNa9MvyPYIj23qAiFUEsyemY5KRk/edit > > This change adds 16 new interpreter opcodes, kStar0 through kStar15, so > that we can use a single byte to represent the common operation of > storing to a low-numbered register. This generally reduces the quantity > of bytecode generated on web sites by 8-9%. > > In order to not degrade speed, a couple of other changes are required: > > The existing lookahead logic to check for Star after certain other > bytecode handlers is updated to check for these new short Star codes > instead. Furthermore, that lookahead logic is updated to contain its own > copy of the dispatch jump rather than merging control flow with the > lookahead-failed case, to improve branch prediction. > > A bunch of constants use bytecode size in bytes as a proxy for the size > or complexity of a function, and are adjusted downward proportionally to > the decrease in generated bytecode size. > > Other small drive-by fix: update generate-bytecode-expectations to emit > \n instead of \r\n on Windows. > > Change-Id: I6307c2b0f5794a3a1088bb0fb94f6e1615441ed5 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2641180 > Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> > Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> > Cr-Commit-Position: refs/heads/master@{#72773} Change-Id: I1afb670c25694498b3989de615858f984a8c7f6f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2698057 Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Reviewed-by:

Previously, ephemerons without a base_object_payload have been filtered. base_object_payload is currently used to differentiate between GarbageCollected and just traceable objects, so we need to pass on the empty descriptor.
