      [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).

      [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.

      [intl] Clean up function name handling in AddBoundMethod · 54ce1935
      adamk authored 
      AddBoundMethod, in i18n.js, returns functions all of which share the
same backing SharedFunctionInfo, which means that its calls to
InstallGetter were causing all such functions to have a single name
(that of the last caller, "get breakType").

This patch skips calling InstallGetter and instead directly calls
%DefineGetterPropertyUnchecked, which itself sets the name property
on the JSFunction instance (it knows how to do this in order to handle
getters that have computed property names).

Also takes care of a TODO having to do with the inner boundMethod:
its name is now made empty, by using a new macro that gets around
ES2015's function name inference.

Finally, removes a redundant %FunctionRemovePrototype: arrow functions
have no prototypes to begin with.

      [runtime] Kill the %NumberToIntegerMapMinusZero runtime entry. · 4b235ade
      bmeurer authored 
      This was initially used to special case some weird date.js behavior, but
has since been abused in other areas. In case of the string character
access, everything that is outside the Smi range cannot be a valid
string index anyways, so %NumberToSmi is perfect here in either case,
and for ToPositiveInteger it's better to just use ToInteger adding +0 to
turn -0 into +0.

      [generators] Decouple generator resume from fullcodegen. · 974721c6
      bmeurer authored 
      Introduce a ResumeGeneratorTrampoline, which does the actual stack state
reconstruction (currently always restores a fullcodegen frame), and
introduce appropriate TurboFan builtins for %GeneratorPrototype%.next,
%GeneratorPrototype%.return and %GeneratorPrototype%.throw based on
this native builtin.

Also unify the flooding in case of step-in to always work based on
JSFunction and remove the special casing for JSGeneratorObject.

      Implement TypedArray(typedarray) constructor · 2fa1c884
      littledan authored 
      The ES2016 draft spec defines a sort of fast path for constructing
a TypedArray based on another TypedArray. This patch implements that
alternative path in TypedArray construction. It is verified by
test262 tests, which now pass. This patch also has a slight cleanup
of TypedArray code by using a macro for TypedArray type checks, as
is done for other types.

This patch includes a minor spec violation: In the same-type case, the
spec indicates that the underlying ArrayBuffer should be copied until
the end, and this is fixed up by making the [[ArrayLength]] shorter.
This is observable with the buffer getter. This patch just copies the
used part of the underlying ArrayBuffer.

      [proxies] Better print for proxies in d8 · 8bfb7189
      cbruni authored 
      Function proxies would not be printed so far since they ended up in Function.prototype.toString which only works with Function as a receiver but no Proxy. Additionally added support for more gracefully dealing with recursive __proto__ structures introduced by proxies.
