      [heap] Implement SimulateFullSpace for PagedNewSpace · 0cd0e4bb
      Omer Katz authored 
      The existing version for paged spaces simply reset the freelist, which
doesn't work for tests that require actual objects in the space.
The version for new space also doesn't work because it assumes
everything after top is free space.

Fill the space with FixedArray by iterating over the freelist and
creating an object in place of each freelist entry.
This method actually fills the space, so that we can also use it to
force page promotion.

      [heap] Rework Worklist base type · a19316d9
      Michael Lippautz authored 
      Worklist uses a singly-linked list of segments to hold entries.
Segment size was based on a compile-time constant but already stored
in the segment itself.

Rework the segments to query `malloc_usable_size()` on allocation and
adjust the capacity properly. For PartitionAlloc, it turns out that
there's ~20% more capacity available for the 64-element segments.

This slows down actual allocation of the segments with the upside of
improving utilization and requiring 20% less segments.

      cppgc: Provide operator==(Raw, Member) to avoid Member decompression · 4dee3fbd
      Anton Bikineev authored 
      The operator with raw pointer allows us to avoid Member decompression,
which is more expensive than compression. It's also quite frequently
called (e.g. in HeapHashSet::find()).

The existing operator
  template <...>
  bool operator==(const Member<T1>&, const Member<T2>&);
was not called for
  GCed* raw = ...;
  member == raw;
because the compiler wouldn't deduce `T2` in `const Member<T2>` as
`GCed` when the initializer expression `raw` is of different type
(`GCed*`).

      Revert "[heap] Sweep code pages on the background thread" · 6ddf042f
      Michael Lippautz authored 
      This reverts commit 8325f86d.

Reason for revert: Speculative revert for chromium:1336850.

Original change's description:
> [heap] Sweep code pages on the background thread
>
> We already make code pages writable & executable for concurrent
> Sparkplug. We can use the same mechanism for sweeping of code pages on
> the background thread, instead of scheduling incremental tasks on the
> main thread. This allows us to remove almost all special
> handling for code pages in the sweeper and allows us to off-load more
> work from the main thread.
