      [heap] Bundle platform-specific constants for CodeRange · b114df1d
      mlippautz authored 
      - Removing null checks as we always have the CodeRange object (it might be
  invalid, but it's there)
- Account for reserved area (Win64) in SetUp so we the caller doesn't need to be
  aware of it

      [heap] Get rid of the wrapper in remembered-set.h · 3ddb2249
      ahaas authored 
      This patch moves the wrapper code from the remembered-set to the
scavenger and the mark-compact code.

The wrapper code inspected a slot address to see if the object that
belongs to the address is in the from-space. If it was in the
from-space, then some callback was executed on the object. If the object
got move to the to-space, then the wrapper returned KEEP_SLOT, otherwise
REMOVE_SLOT.

This logic does not really belong to the remembered set, so I moved it
away from there.

      [serializer] do not cache resource data pointer for native source. · 28df32d9
      yangguo authored 
      The cached resource data pointer is a source of non-determinism when
creating the snapshot.  Long-term we may not keep the native source in
memory anyways, so caching the resource data pointer will not be
possible.

      [es6] Reintroduce the instanceof operator in the backends. · 551e0aa1
      bmeurer authored 
      This adds back the instanceof operator support in the backends and
introduces a @@hasInstance protector cell on the isolate that guards the
fast path for the InstanceOfStub. This way we recover the ~10%
regression on Octane EarleyBoyer in Crankshaft and greatly improve
TurboFan and Ignition performance of instanceof.

      Revert of [heap] Uncommit pooled pages concurrently (patchset #5 id:120001 of https://codereview.chromium.org/1913083002/ )

Reason for revert:
Creates a spike of OOM(v8) crashers on Win32.

Original issue's description:
> [heap] Uncommit pooled pages concurrently

> - Hide (private) members where possible
> - MemoryAllocator:Free is now the bottleneck for freeing
> - Pooled pages are either allocated from a set of pooled pages are obtained
>   through work stealing from the concurrent unmapper

      disallow left-trim fast path when sampling heap profiler is active · 2837cb38
      ofrobots authored 
      Left trimming assumes that nobody other than the JSArray has a reference to the
backing store. Sampling heap profiler may profile the backing store and keep a
reference too it. This reference was never updated on a left-trim, causing a
crash.

      Improved diagnostic message for JS heap out of memory · 1ef7487b
      richard_chamberlain authored 
      This patch replaces the unused 'take_snapshot' parameter on FatalProcessOutOfMemory()
with a 'is_heap_oom' parameter. The parameter is set to true on error paths where the
JS heap is out of memory, as distinct from a malloc() failure i.e. process out of memory.
The message output to stderr or passed to embedding applications via FatalErrorCallback
is 'Javascript heap out of memory' rather than 'process out of memory'.
