Add fields to HeapOptions to denote on heap creation that the heap does not support incremental/concurrent marking/sweeping. This only applies to standalone heaps. When triggering a GC (either explicitly or by the heap growing heuristics), the given config is limited to not trigger unsupported marking/sweeping types.

Exposes an opaque handle for uniformly (cppgc and V8) referring to an instance of a heap. Exposes a set of raw write barriers for advances embedders through subtle::HeapConsistency which is a mirror into write barrier internals. The following barriers are exposed: - DijkstraWriteBarrier: Regular Dijkstra-style write barrier (add to wavefront); - DijkstraWriteBarrierRange: Same as DijkstraWriteBarrier but operating on a range of slots that are composite (inlined) objects; - SteeleWriteBarrier: Regular Steele-style write barrier (retreating wavefront); Change-Id: Ib5ac280204686bf887690f72df1cdb506ea6ef70 Bug: chromium:1056170 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2554601Reviewed-by:

Unified heap support in V8 requires having another (at least internal) heap that implements a unfied garbage collection strategy. This will not re-use the already existing cppgc::Heap because there should be no way in creating such a heap externally or scheduling stand-alone garbage collections. In order to have a common token, this CL introduces AllocationHandle which can be passed to MakeGarbageCollected to allocate C++ objects. V8 (soon) and the stand-alone heap both have methods to retrieve such a handle. This works around a problem with creating diamond class hierarchies when a base class would be exposed on the public API level. Fast paths for Blink are still possible because allocation handles can be cached the same way (e.g. global, or TLS) as a heap can be cached.

Adds allocation-based heap growing strategy that triggers GC based on some limit. The limit is computed based on previous live memory and a constant growing factor. For invoking GC, we support two modes: with and without conservative stack scanning. Without conservative stack scanning, an invoker makes sure that we schedule a GC without stack using the existing platform.

Split platform into a process-global initialization part and per-heap platform objects. These platform objects still contain allocators and executors. With per-heap platforms GetForegroundTaskRunner() returns by definition the correct runner. In future, when initialized throuhg V8, an adapter can be used to translate between the different platforms, avoiding the needed for V8 embedders to provide additional information.

This CL adds 2 new values to the EmbedderStackState enum with more explicit names. The old values are updated as aliases to the new values and marked as soon to be deprecated. This CL also moves the enum to v8-platform.h so that it can be reused by cppgc. Depracating individual values in an enum is supported by GCC only since version 6. Thus new macros were needed for the deprecation (which delegate to the existing macros when supported). GCC versions older than 6 are still used by the CQ bots.

This patch provides infrastructure to pin object types to specific spaces. This allows embedders to create mutual exclusive arenas for certain (base) types. In future, this will also be used to provide sliding-window compaction on certain custom spaces. We mainly preserve the existing infrastructure with the difference that spaces are now slightly more dynamic than in Blink as they are kept in a vector instead of a fixed-size array. The mechanism differs from Blink in that it does not allow the user object to call allocation methods directly but instead provides a trait that can be overridden to specify a custom space. The patch preserves templatization for objects that do not go into custom spaces to safe a branch in the allocation hot path.
