      [runtime] Remove try_fast path from GetOwnPropertyNames builtin · b048429e
      Mythri A authored
      GetOwnPropertyNameTryFast uses ENUMERABLE_STRINGS filter to trigger fast
      path in KeyAccumulator::GetKeys conditionally when all properties on the
      receiver are enumerable. It is not easy to verify if all properties are
      enumerable and the current check is incorrect in some cases.
      For ex: when we have non-enumerable properties when we have elements on
      the receiver. This cl removes this try_fast path from the builtin. This
      could impact performance. The long term fix for this would be to fix
      KeyAccumulator::GetKeys to use fast path for more cases.

      Reland "[typedarray] Make JSTypedArray::length authoritative." · 330e5ba2
      Peter Marshall authored
      This is a reland of ad44c258
      
      Patchset 2 is the original CL
      Patchset 3 fixes some misuses of FixedArrayBase::length() and adds some
      DCHECKS to flush out any more misuses.
      Patchset 4 adds the PPC/S390 port by miladfar@ca.ibm.com.

      [typedarray] Make JSTypedArray::length authoritative. · ad44c258
      Benedikt Meurer authored
      This is the first step towards full huge typed array support in V8.
      Before this change, the JSTypedArray::length and the elements backing
      store length (FixedTypedArrayBase::length) were used more or less
      interchangeably to determine the number of elements in a JSTypedArray.
      
      With this change we disentangle these two lengths, and instead make
      JSTypedArray::length authoritative. For on-heap typed arrays, the
      FixedTypedArrayBase::length will remain the number of elements in the
      backing store, but for the off-heap typed arrays, this length will be
      set to 0 (matching the fact that the FixedTypedArrayBase instance does
      not contain any elements itself).
      
      This also unifies the JSTypedArray::set_/length() and length_value()
      methods to only have JSTypedArray::set_/length() which returns/takes
      size_t values. Currently this still requires the values to be in Smi
      range, but later we will extend this to allow arbitrary size_t values
      (in the safe integer range).
