      [offthread] Change OffThreadIsolate to LocalIsolate · f1589bbe
      Leszek Swirski authored
      This patch introduces a new LocalIsolate and LocalFactory, which use
      LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows
      us to remove those classes, as well as the related OffThreadSpace,
      OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle.
      OffThreadLogger becomes LocalLogger.
      
      LocalHeap behaves more like Heap than OffThreadHeap did, so this allows
      us to additionally remove the concept of "Finish" and "Publish" that the
      OffThreadIsolate had, and allows us to internalize strings directly with
      the newly-concurrent string table (where the implementation can now move
      to FactoryBase).
      
      This patch also removes the off-thread support from the deserializer
      entirely, as well as removing the LocalIsolateWrapper which allowed
      run-time distinction between Isolate and OffThreadIsolate. LocalHeap
      doesn't support the reservation model used by the deserializer, and we
      will likely move the deserializer to use LocalIsolate unconditionally
      once we figure out the details of how to do this.

      [heap] Remove PagedSpace::SizeOfObjects · ab8368df
      Dominik Inführ authored
      PagedSpace::SizeOfObjects() then returns exactly the same value as
      PagedSpace::Size(). SizeOfObjects() used to deduct the current LAB,
      however this is now more difficult with local heaps. Accessing the
      main thread LAB from concurrent threads causes a data race. Also
      LocalHeaps have their own LAB, which should be deducted as well to be
      uniform with the main thread. However this would be tricky and expensive.
      The simpler solution is to do not deduct the main thread LAB anymore.

      [heap] Use BasicMemoryChunk::FromHeapObject more · 6f267e8a
      Dan Elphick authored
      Since ReadOnlySpace pages will soon not be MemoryChunks, change most
      uses of MemoryChunk::FromHeapObject and FromAddress to use the
      BasicMemoryChunk variants and which use the new MemoryChunk::cast
      function that takes a BasicMemoryChunk and DCHECKs !InReadOnlySpace().
      
      To enable this, it also moves into BasicMemoryChunk several MemoryChunk
      functions that just require a BasicMemoryChunk.

      [heap] Make ReadOnlySpace use bump pointer allocation · 81c34968
      Dan Elphick authored
      This changes ReadOnlySpace to no longer be a PagedSpace but instead it
      is now a BaseSpace. BasicSpace is a new base class that Space inherits
      from and which has no allocation methods and does not dictate how the
      pages should be held.
      
      ReadOnlySpace unlike Space holds its pages as a
      std::vector<ReadOnlyPage>, where ReadOnlyPage directly subclasses
      BasicMemoryChunk, meaning they do not have prev_ and next_ pointers and
      cannot be held in a heap::List. This is desirable since with pointer
      compression we would like to remap these pages to different memory
      addresses which would be impossible with a heap::List.
      
      Since ReadOnlySpace no longer uses most of the code from the other
      Spaces it makes sense to simplify its memory allocation to use a simple
      bump pointer and always allocate a new page whenever an allocation
      exceeds the remaining space on the final page.

      [offthread] Make publish merging and handle fixup atomic · bbc8f787
      Leszek Swirski authored
      Make sure that any GCs required for off-thread heap merging happen
      before any off-thread handle transferring (both transferring using
      OffThreadTransferHandle, and the handles created for the string slot
      fixups). This is to avoid the marker from walking Handle roots that
      point into off-thread pages which the sweeper doesn't see (and can't
      clear mark bits on)
      
      Now, the merging and handle creation is atomic as far as the GC is
      concerned. The merging is done before handle creation to avoid the
      incremental marker from entering off-thread pages, but we ensure that
      the raw objects pointers that point into the off-thread pages (which
      are used for creating the main-thread handles) stay valid until the
      handle creation completes.
      
      Since handle transfer now happens in the middle of publishing, this
      patch also moves the OffThreadTransferHandleStorage ownership over to
      OffThreadHeap. This requires some header juggling to avoid leaking
      OffThreadTransferHandleStorage into the off-thread-isolate header.
