The CompareOperationFeedback documentation was outdated and there was an invalid TODO on it that suggested to unify this with the BinaryOperationFeedback which in retrospect doesn't make a lot of sense.

This helps to debug issues with maintaining the cache state, and also understanding errors in the generated code. Unfortunately, it requires buffering the trace output in the decoder, since the interface is called in between, and the output would be messed up otherwise.

For the JS object allocation case, we materialize children_count - 1 objects. However, we already materialized the map and property array, so this could materialize one object beyond the JS object. If there is no such object, we would go out-of-bounds.

This relands commit e71b8022. This can now back in as the fix for chromium:787301 had enough time to be tested in Canary. Original change's description: > [deoptimizer] Staged materialization of objects. > > The existing object materialization in the deoptimizer has the following problems: > > - Objects do not necessarily verify during materialization (because during the > depth first walk we might have inconsistent objects). > > - Stack can overflow (because we just materialize using recursive calls). > > - We generalize object fields. > > > This CL re-implements the materialization algorithm to solve this problem. The > new implementation creates the objects in two steps: > > 1. We allocate space for all the objects. In general, we allocate ByteArrays > of the right size. For leaf objects that cannot participate in cycles, > we build and initialize the materialized objects completely. > > For JS objects, we insert markers into the byte array at the positions > where unboxed doubles are expected. > > 2. We initialize all the objects with the proper field values and change the > map from the ByteArray map to the correct map. This requires some sync > with the concurrent marker (Heap::NotifyObjectLayoutChange). > > When initializing the JS object fields, we make sure that we respect > the unboxed double marker. > > Bug: chromium:770106, v8:3836 > Change-Id: I1ec466a9d19db9538df4ba915516d4c3ca825632 > Reviewed-on: https://chromium-review.googlesource.com/777559 > Commit-Queue: Jaroslav Sevcik <jarin@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Michael Starzinger <mstarzinger@chromium.org> > Cr-Commit-Position: refs/heads/master@{#49821} Bug: chromium:770106, v8:3836 Change-Id: Ied6c4e0fbae52713e55ae6dc13794a7521dbb8a5 Reviewed-on: https://chromium-review.googlesource.com/817745Reviewed-by:

NewSpace::UpdateInlineAllocationLimit was computing the limit slighly differently. Make old space and new space more consistent. The way new space does it makes more sense as, logically, the step starts from beyond the current object being allocated (size_in_bytes). This behaviour change in preperation for a subsequent CL that refactors a common SpaceWithLinearArea::ComputeLimit.

If the fixed array is being concurrently left-trimmed then checked getter can assert because the length is not necessarily a Smi. This patch uses unchecked length getter to cache the length as Object*. Only if the marker manages to color the array black, we are guaranteed that the cached length is a Smi. This patch also uses unchecked cast for FixedArray in HeapVisitor for concurrent marker. Note that this patch only affects debug mode.
