Source/JavaScriptCore:

The idea behind the GC verifier is that in the GC End phase before we finalize
and sweep, we'll do a simple stop the world synchronous full GC with the
VerifierSlotVisitor.  The VerifierSlotVisitor will collect it's own information
on whether a JS cell should be marked or not.  After this verifier GC pass, we'll
compare the mark results.

If the verifier GC says a cell should be marked, then the real GC should have
marked the cell.  The reverse is not true: if the verifier does not mark a cell,
it is still OK for the real GC to mark it.  For example, in an eden GC, all old
generation cells would be considered mark by the real GC though the verifier would
know better if they are already dead.

Implementation details:

1. SlotVisitor (only used by the real GC) now inherits from a new abstract class,
   AbstractSlotVisitor.

   VerifierSlotVisitor (only used by the verifier GC) also inherits from
   AbstractSlotVisitor.

2. AbstractSlotVisitor declares many virtual methods.

   SlotVisitor implements some of these virtual methods as inline and final.
   If the client is invoking one these methods and knows that it will be operating
   on a SlotVisitor, the method being final allows it to be inlined into the client
   instead of going through the virtual dispatch.

   For the VerifierSlotVisitor, these methods will always be invoked by virtual
   dispatch via the AbstractSlotVisitor abstraction.

3. Almost all methods that takes a SlotVisitor previously (with a few exceptions)
   will now be templatized, and specialized to either take a SlotVisitor or an
   AbstractSlotVisitor.

   The cell MethodTable will now have 2 versions of visitChildren and visitOutputConstraints:
   one for SlotVisitor, and one for AbstractSlotVisitor.

   The reason we don't wire the 2nd version to VerifierSlotVisitor (instead of
   AbstractSlotVisitor) is because we don't need the GC verifier to run at top
   speed (though we don't want it to be too slow).  Also, having hooks for using
   an AbstractSlotVisitor gives us more utility for implementing other types of
   GC checkers / analyzers in the future as subclasses of AbstractSlotVisitor.

4. Some minority of methods that used to take a SlotVisitor but are not critical
   to performance, will now just take an AbstractSlotVisitor instead.  For example,
   see TypeProfilerLog::visit().

5. isReachableFromOpaqueRoots() methods will also only take an AbstractSlotVisitor.

   The reason this is OK is because isReachableFromOpaqueRoots() only uses the
   visitor's addOpaqueRoot() and containsOpaqueRoot() methods, which are implemented
   in the AbstractSlotVisitor itself.

   For SlotVisitor, the m_opaqueRoot field will reference Heap::m_opaqueRoots.
   For VerifierSlotVisitor, the m_opaqueRoot field will reference its own
   opaque roots storage.

   This implementation of addOpaqueRoot() is perf neutral for SlotVisitor because
   where it would previously invoke m_heap.m_opaqueRoots.add(), it will now
   invoke m_opaqueRoot.add() instead where m_opaqueRoot points to m_heap.m_opaqueRoots.

   Ditto for AbstractSlotVisitor::containsOpaqueRoot().

6. When reifying a templatized visit method, we do it in 2 ways:

   a. Implement the template method as an ALWAYS_INLINE Impl method, and have
      2 visit methods (taking a SlotVisitor and an AbstractSlotVisitor respectively)
      inline the Impl method.  For example, see JSObject::visitChildrenImpl().

   b. Just templatize the visit method, and explicitly instantiate it with a SlotVisitor
      and an AbstractSlotVisitor.  For example, see DesiredTransition::visitChildren().

   The reason we need form (a) is if:

    i. we need to export the visit methods.
       For example, see JSObject:visitChildren().

       Note: A Clang engineer told me that "there's no way to export an explicit
       instantiation that will make it a strong symbol."  This is because "C++ does not
       provide any standard way to guarantee that an explicit instantiation is unique,
       and Clang hasn't added any extension to do so."

   ii. the visit method is an override of a virtual method.
       For example, see DFG::Scannable::visitChildren() and DFG::Graph::visitChildren().

   Otherwise, we'll prefer form (b) as it is natural C++.

7. Because templatizing all the visit methods requires a lot of boiler plate code,
   we introduce some macros in SlotVisitorMacros.h to reduce some of the boiler
   plate burden.

   We especially try to do this for methods of form (a) (see (6) above) which
   require more boiler plate.

8. The driver of the real GC is MarkingConstraintSet::executeConvergence() which
   runs with the MarkingConstraintSolver.

   The driver of the verifier GC is Heap::verifyGC(), which has a loop to drain
   marked objects and execute contraints.

9. The GC verifier is built in by default but disabled.  The relevant options are:
   JSC_verifyGC and JSC_verboseVerifyGC.

   JSC_verifyGC will enable the GC verifier.

   If JSC_verifyGC is true and the verifier finds a cell that is
   erroneously not marked by the real GC, it will dump an error message and then
   crash with a RELEASE_ASSERT.

   JSC_verboseVerifyGC will enable the GC verifier along with some more heavy
   weight record keeping (i.e. tracking the parent / owner cell that marked a
   cell, and capturing the call stack when the marked cell is appended to the mark
   stack).

   If JSC_verboseVerifyGC is true and the verifier finds a cell that is
   erroneously not marked by the real GC, it will dump the parent cell and
   captured stack along with an error message before crashing.  This extra
   information provides the starting point for debugging GC bugs found by the
   verifier.

   Enabling JSC_verboseVerifyGC will automatically enable JSC_verifyGC.

10. Non-determinism in the real GC.

   The GC verifier's algorithm relies on the real GC being deterministic.  However,
   there are a few places where this is not true:

   a. Marking conservative roots on the mutator stacks.

      By the time the verifier GC runs (in the GC End phase), the mutator stacks
      will look completely different than what the real GC saw.  To work around
      this, if the verifier is enabled, then every conservative root captured by
      the real GC will also be added to the verifier's mark stack.

      When running verifyGC() in the End phase, the conservative root scans will be
      treated as no-ops.

   b. CodeBlock::shouldJettisonDueToOldAge() may return a different value.

      This is possible because the codeBlock may be in mid compilation while the
      real GC is in progress.

      CodeBlock::shouldVisitStrongly() calls shouldJettisonDueToOldAge(), and may
      see an old LLInt codeBlock whose timeToLive has expired.  As a result,
      shouldJettisonDueToOldAge() returns true and shouldVisitStrongly() will
      return false for the real GC, leading to it not marking the codeBlock.

      However, before the verifier GC gets to run, baseline compilation on the
      codeBlock may finish.  As a baseline codeBlock now, it gets a longer time
      to live.

      As a result, when the verifier GC runs, shouldJettisonDueToOldAge() will
      return false, and shouldVisitStrongly() in turn returns true.  This results
      in the verifier GC marking the codeBlock (and its children) when the real
      GC did not, which leads to a false error.  This is not a real error because
      if the real GC did not mark the code block, it will simply get jettisoned,
      and can be reinstantiated when needed later.  There's no GC bug here.
      However, we do need to work around this to prevent the false error for the
      GC verifier.

      The work around is to introduce a CodeBlock::m_visitChildrenSkippedDueToOldAge
      flag that records what the real GC decided in shouldJettisonDueToOldAge().
      This allows the verifier GC to replay the same decision and get a consistent
      result.

   c. CodeBlock::propagateTransitions() will only do a best effort at visiting
      cells in ICs, etc.  If a cell is not already strongly marked by the time
      CodeBlock::propagateTransitions() checks it, propagateTransitions() will
      not mark other cells that are reachable from it.

      Since the real GC does marking on concurrent threads, marking order is not
      deterministic.  CodeBlock::propagateTransitions() may or may not see a cell
      as already marked by the time it runs.

      The verifier GC may mark some of these cells in a different order than the
      real GC.  As a result, in the verifier GC, CodeBlock::propagateTransitions()
      may see a cell as marked (and therefore, visit its children) when it did
      not for the real GC.

      To work around this, we currently add a SuppressGCVerifierScope to
      CodeBlock::propagateTransitions() to pessimize the verifier, and assume that
      propagateTransitions() will mark nothing.

      SuppressGCVerifierScope is a blunt hammer that stops the verifier GC from
      analyzing all cells potentially reachable via CodeBlock::propagateTransitions().
      In the future, it may be possible to refine this and track which cells were
      actually skipped over (like we did for shouldJettisonDueToOldAge()).
      However, this decision tracking needs to be done in the real GC, and can be
      very expensive in terms of performance.  The shouldJettisonDueToOldAge()
      case is rare, and as such lends itself to this more fine grain tracking
      without hurting performance.  The decisions made in CodeBlock::propagateTransitions()
      are not as rare, and hence, it would hurt performance if we did fine grain
      decision tracking there (at least or now).

11. Marking in the verifier GC.

    The real GC tracks cell marks using a Bitmap in the MarkedBlocks.  The verifier
    GC keeps tracks of MarkedBlock cell marks using a Bitmap on the side, stashed
    away in a HashMap.

    To improve the verifier marking performance, we reserve a void* m_verifierMemo
    pointer in the MarkedBlock, which the verifier will employ to cache its
    MarkedBlockData for that MarkedBlock.  This allows the verifier to get to its
    side Bitmap without having to do a HashMap look up for every cell.

    Size-wise, in the current 16K MarkBlocks, there is previously room for 1005.5
    atoms after reserving space for the MarkedBlock::Footer.  Since we can never
    allocate half an atom anyway, that .5 atom gives us the 8 bytes we need for
    the m_verifierMemo pointer, which we'll put in the MarkedBlock::Footer.  With
    this patch, each MarkedBlock will now have exactly 1005 atoms available for
    allocation.

I ran JetStream2 and Speedometer2 locally on a MacBookAir10,1, MacBookPro16,1,
and a 12.9” 4th Gen iPad Pro.  The benchmark results for these were all neutral.

The design of the GC verifier is such that it incurs almost no additional runtime
memory overhead if not in use.  Code size does increase significantly because
there are now 2 variants of most of the methods that take a SlotVisitor.

When in use, the additional runtime memory is encapsulated in the
VerifierSlotVisitor, which is instantiated and destructed every GC cycle.  Hence,
it can affect peak memory usage during GCs, but the cost is transient.  It does
not persist past the GC End phase.
