Use an atomic marking state in all builds - even builds with concurrent marking disabled. This will allow us to simplify our code a bit. This CL starts by always using MajorMarkingState for MarkCompactCollector::MarkingState and removing V8_ATOMIC_MARKING_STATE.

When performing a shared GC, we need to find references from the client heaps into the shared heaps. For now we achieve this by simply iterating all objects in client heaps. We need to do this both for marking and when updating pointers after evacuation.

Samuel Groß authored
This interface is meant to eventually replace the existing v8::PageAllocator interface. Beyond general refactoring of the PageAllocator APIs, the new interface now supports the concept of (contiguous) address space reservations, which previously had to be implemented through page allocations. These reservations now make better use of provided OS primitives on Fuchsia (VMARs) and Windows (placeholder mappings) and can be used to back many of the cages and virtual memory regions that V8 creates. The new interface is not yet stable and may change at any time without deprecating the old version first.

When pntr compression is enabled, `Pointer()` reads 8 bytes whereas `TaggedPointer()` reads 4 bytes and decompresses. TaggedPointer() in this case was causing an incorrect read on big endian as the desired value was located on the high side of memory. Similar patches were also applied in this CL: https://crrev.com/c/2057355 Change-Id: I77c449256ae1f56f2f8664f687985221badf819f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3314302 Commit-Queue: Milad Farazmand <mfarazma@redhat.com> Reviewed-by:

Previously, StoreStoreElimination handled allocations as "can observe anything". This is pretty conservative and prohibits elimination of repeated double stores to the same field. With this CL allocations are changed to "observes initializing or transitioning stores". This way it is guaranteed that initializing stores to a freshly created object or stores that are part of a map transition are not eliminated before allocations (that can trigger GC), but allows elimination of non-initializing, non-transitioning, unobservable stores in the presence of allocations.

Leszek Swirski authored
Rather than creating a ParseInfo when creating a BackgroundCompileTask (and passing ownership across to the BG thread which deallocates it), create one when running it. This allows the ParseInfo Zone to be both allocated and deallocated on the same thread, which will improve its allocator friendliness. As a side-effect, we now use the on-heap PreparseData from the SharedFunctionInfo, rather than cloning the in-Zone PreparseData. This means that we don't have to copy the PreparseData across Zones, but we do need to Unpark the LocalHeap when accessing preparse data.

This CL turns references to ArrayBuffer backing stores from JSArrayBuffers, JSTypedArrays, and JSDataViews into CagedPointers when those are enabled. CagedPointers cannot generally represent nullptr, as NULL usually lies outside the cage. As such, nullptr backing stores are replaced with a special empty backing store value, which, in the current implementation, points to the end of the cage, right in front of the trailing guard regions. Due to this, it is no longer correct to compare a backing store pointer against nullptr.

This allows streamed sources to also trigger parallel compile tasks. The chunk vectors are shared via std::shared_ptr. Clone chunked streams are initialised with a null source, and are not allowed to fetch any more data. Similarly, the original stream is not allowed to fetch data if it has been cloned (since the vector is shared and would mutate if we added more data to it). This is ok for the purposes of cloning for parallel compile tasks, as we fully parse before cloning for the task.
