      [promises] port NewPromiseCapability to TF · 4f95a1eb
      caitp authored 
      - Adds CodeAssembler::ConstructJS() to simplify calling JS functions as
constructors, used by NewPromiseCapability()
- Defines PromiseCapability as a special JSObject subclass, with a
non-exensible Map, and read-only non-configurable DataDescriptors which
point to its in-object fields. This allows its fields to be used by JS
builtins until there is no longer any need.

Currently, the performance benefit comes from
https://codereview.chromium.org/2567033003/, but does not appear to
regress performance in any significant way.

      Add unittests to keep InstanceType lists in sync · c0282f60
      cbruni authored 
      STRUCT_LIST and INSTANCE_TYPE_LIST are now forced to have the same order
as the InstanceType enum.

Drive-by-fix 1: Move type check and cast functions closer together in objects-inl.h

Drive-by-fix 2: Remove unused instance types SIGNATURE_INFO_TYPE and  TYPE_SWITCH_INFO_TYPE.

      [builtins] implement Array.prototype[@@iterator] in TFJ builtins · 86d0dd36
      caitp authored 
      Implements the variations of CreateArrayIterator() in TFJ builtins
(ArrayPrototypeValues, ArrayPrototypeEntries and ArrayPrototypeKeys), and
provides two new Object types with numerous maps which identify certain
behaviours, which will be useful for inlining.

Removes src/js/array-iterator.js entirely

Also adds support for printing Symbol literals inserted by the Parser during
desugaring when FLAG_print_builtin_ast is set to true.

      Forking the type system between Crankshaft & Turbofan. · 17e9e2f4
      mvstanton authored 
      Our Type class has a semantic and representational dimension.
Much code in src/ast, Crankshaft and Turbofan is based on it.
Going forward in Turbofan we'd like to remove representational information
entirely. To that end, new type AstType has been created to preserve
existing behavior for the benefit of Crankshaft and the AST.

      Revert of Use a custom Struct for stack trace storage (patchset #4 id:60001 of https://codereview.chromium.org/2230953002/ )

Reason for revert:
Performance regressions in Gameboy, Life, CodeLoad and others. See crbug.com/638210.

      Refactor data structures for simple stack traces · b4c1aefb
      jgruber authored 
      Simple stack traces are captured through Isolate::CaptureSimpleStackTrace.
Captured frames are stored in a FixedArray, which in turn is stored as a
property (using a private symbol) on the error object itself. Actual formatting
of the textual stack trace is done lazily when the user reads the stack
property of the error object.

This would involve many conversions back and forth between index-encoded raw
data (receiver, function, offset and code), JS CallSite objects, and C++
CallSite objects.

This commit refactors the C++ CallSite class into a Struct class called
StackTraceFrame, which is the new single point of truth frame information.
Isolate::CaptureSimpleStackTrace stores an array of StackTraceFrames, and JS
CallSite objects (now created only when the user specifies custom stack trace
formatting through Error.prepareStackTrace) internally only store a reference
to a StackTraceFrame.
