      PPC: [Interpreter] Add basic deoptimization support from TurboFan to Ignition. · f5261a6a
      mbrandy authored 
      Port b10d24ff

Original commit message:
    Adds support for generating deoptimization translations for interpreter
    stack frames, and building interpreter frames for these translations
    when a function deopts. Also adds builtins for
    InterpreterNotifyDeoptimized which resume the function's continuation at
    the correct point in the interpreter after deopt.

      [arm64] Improve some new builtins. · efc641a7
      jacob.bramley authored 
      - Simplify the variable-length pop sequence on entry. (It now uses
  smaller code with no branches.)
- Use conditional compare to merge branches where appropriate.
- Make use of Ldrsw + UntagSmiFieldMemOperand to load smis more
  efficiently.
- Only load 'undefined' and 'null' once per builtin.
- A few other small improvements.

      PPC: [es6] Correct Function.prototype.apply, Reflect.construct and Reflect.apply. · 36afb789
      mbrandy authored 
      Port 5bd48324

Original commit message:
    Introduce a new Apply builtin that forms a correct and optimizable
    foundation for the Function.prototype.apply, Reflect.construct and
    Reflect.apply builtins (which properly does the PrepareForTailCall
    as required by the ES2015 spec).

    The new Apply builtin avoids going to the runtime if it is safe to
    just access the backing store elements of the argArray, i.e. if you
    pass a JSArray with no holes, or an unmapped, unmodified sloppy or
    strict arguments object.

      PPC: [runtime] Drop FIRST/LAST_NONCALLABLE_SPEC_OBJECT instance type range. · 5c33ac6c
      mbrandy authored 
      Port aafc3e54

Original commit message:
    The FIRST-LAST_NONCALLABLE_SPEC_OBJECT_TYPE range was accidentially used
    in field type tracking, where we should check for JSReceiver instead
    (there's no need to exclude JSProxy or JSFunction from tracking).

    And the use in %_ClassOf was actually wrong and didn't match the C++
    implementation in JSReceiver::class_name() anymore. Now it's consistent
    again.

      PPC: [turbofan] Fixed the second return value of TryTruncateFloatXXToUint64. · 98cf7310
      mbrandy authored 
      Port 0794c3c9

Original commit message:
    As required by the spec, the second return value now returns success
    also for the range between 0 and -1 where the conversion results in 0.

      [heap] Move to LAB-based allocation for newspace evacuation. · a4e3a3b6
      mlippautz authored 
      This CL prepare newspace evacuation for parallel execution wrt. to actual
allocations. The priority for allocations is:
* Try to allocate from LAB if objects are below kMaxLabObjectSize
* Allocate directly (synchronized) from newspace for larger objects.
* Fall back to old space allocation (which will be backed by a local compaction
  space in future).

Semantical change: Previously we did fall back to regular new space promotion if
we are OOM in old space. With this CL we fall back to new space promotion, which
could fail because of fragmentation, again leading to an old space allocation
that finally bails into OOM.

Newspace evacuation is still single threaded and requires further changes to
allocation site tracking.
