      [runtime-call-stats] Fix the threading check in debug mode. · c408123d
      Alexei Filippov authored 
      The RuntimeCallStats object happen to be created on the main thread,
but then got used in a worker. Make sure the thread checks do not
fire false positives in this case.

      [wasm] Add thread-in-wasm flag builtins for x64 target · 527d5568
      Eric Holk authored 
      This was causing trouble with Fuchsia, since mksnapshot was built and run on
Linux which supports trap handlers, while Fuchsia does not yet. This change
causes the external references to match between Fuchsia and Linux.

      This reverts commit 6ddb5e7d.

Original change's description:

> 
> Now, the EffectControlLinearizer connects all occurrences of Unreachable to the 
> graph end. This fixes issues with later phases running DeadCodeElimination and
> introducing new DeadValue nodes when processing uses of Unreachable.

      [turbofan] Simplify Map#has lowering. · f5f42639
      Benedikt Meurer authored 
      We don't need an explicit diamond in JSBuiltinReducer to produce a
Boolean. The NumberEqual operator already produces a Boolean, so we
just need to negate the result.

      [collections] Refactor map entry lookup and make naming more consistent. · 130cee39
      Benedikt Meurer authored 
      Rename the MapLookupHashIndex builtin to FindOrderedHashMapEntry and
also rename the TurboFan operators LookupHashStorageIndex and
LookupSigned32HashStorageIndex to FindOrderedHashMapEntry and
FindOrderedHashMapEntryForInt32Key respectively. This way the naming is
more consistent and it's immediately obvious from the operator name that
this operator deals with OrderedHashMaps, which wasn't clear before.

Also fix the result of the operation to be either -1 or the index of
the entry relative to the hash table start (that is, no longer eagerly
add hash table start plus value offset to the entry index). This removes
this non-foldable integer additon from TurboFan code for both Map#get
and Map#has.

Drive-by-fix: Also provide more concrete types for the
FindOrderedHashMapEntry operators.

      We use the naming convention <Constructor>Prototype<Method> for builtins
that implement methods on a certain builtin constructors prototype. Fix
the collection builtins (Map and Set) to match this naming convention.
