      [regexp] Turn last match info into a simple FixedArray · f60a7c4f
      jgruber authored
      Now that all accesses to the last match info are in C++ and TF code, we can
      finally turn the last match info into a FixedArray. Similar to the ArrayList,
      it uses its first field to store its length and grows dynamically in amortized
      O(1) time.
      
      Unlike previously, this means that the last match info pointer stored on the
      context can actually change (in case the FixedArray needs to grow).

      [stubs] Port SubStringStub to TurboFan · 49be3192
      jgruber authored
      This ports the platform-specific SubStringStub to TurboFan.
      
      It also contains a minor bug-fix for the case when the requested substring
      length equals the subject string length, but the start index is not equal to 0.
      The old stub implementation returned the subject string, while the new
      implementation calls into runtime, which finally results in a thrown exception.

      [stubs] Port StoreTransitionStub and ElementsTransitionAndStoreStub to TurboFan. · 130d9893
      ishell authored
      This CL also cleans up related interface descriptors:
      1) unused StoreTransitionDescriptor is removed and VectorStoreTransitionDescriptor is
      renamed to StoreTransitionDescriptor.
      2) on ia32/x87 architectures slot and vector are passed on the stack (dispatcher/handlers
      cleanup will be addressed in a separate CL).
      
      These two stub ports have to be combined in one CL because:
      1) without changing the StoreTransitionDescriptor TF was not able to compile them
      on ia32/x87 (because of lack of registers),
      2) it was not possible to change the descriptor first because Crankshaft was not able
      to deal with the stack allocated parameters in case of a stub failure.

      Record call counts also for megamorphic calls. · 2ab3fcf4
      mvstanton authored
      To make better inlining decisions, it's good to have call counts for poly/mega-morphic cases. This CL makes it work for calls, and another will follow to better unify the code between constructor calls and normal calls (and thence, to record megamorphic call counts there as well).

      Move kMaxRegularHeapObjectSize into globals · 059b5643
      mlippautz authored
      This way we avoid the cyclic dependency between objects.h and heap.h and still
      have one definition. Add a static assert that this size is indeed smaller than
      the payload of a page.
      
      Follow ups can finally remove the dependency on spaces.h for all heap.h users.

      [regexp][liveedit] Fix inconsistent JSArrays · bb9707c8
      jkummerow authored
      The hand-written KeyedLoadIC_Megamorphic stub didn't care about JSArray
      lengths, which made it lenient towards said lengths being wrong, but it
      will soon fix that bug and thereby become more strict.
      
      LiveEdit: factory->NewJSArray(capacity) doesn't set a length, so set it
      manually.
      RegExp: to avoid having to take care of array length updating in the
      RegExpExecStub, just use a JSObject instead.

      [builtins] New frame type for exits to C++ builtins · 5febc27b
      jgruber authored
      Prior to this commit, calls to C++ builtins created standard exit
      frames, which are skipped when constructing JS stack traces. In order to
      show these calls on traces, we introduce a new builtin exit frame type.
      
      Builtin exit frames contain target and new.target on the stack and are
      not skipped during stack trace construction.

      [turbofan] Introduce Float64Pow and NumberPow operators. · e607e12e
      bmeurer authored
      Introduce a new machine operator Float64Pow that for now is backed by
      the existing MathPowStub to start the unification of Math.pow, and at
      the same time address the main performance issue that TurboFan still has
      with the imaging-darkroom benchmark in Kraken.
      
      Also migrate the Math.pow builtin itself to a TurboFan builtin and
      remove a few hundred lines of hand-written platform code for special
      handling of the fullcodegen Math.pow version.

      This fixes FastNewStrictArgumentsStub and FastNewRestParameterStub to no

      into new-space. The case where said object needs to move to large object
      space is now handled in the runtime.
