      PPC: [undetectable] Really get comparisons of document.all right now. · eaa38ad1
      mbrandy authored 
      Port 679d9503

Original commit message:
    According to https://www.w3.org/TR/html5/obsolete.html#dom-document-all,
    comparisons of document.all to other values such as strings or objects,
    are unaffected. In fact document.all only gets special treatment in
    comparisons with null or undefined according to HTML. Especially setting
    the undetectable doesn't make two distinct JSReceivers equal.

      PPC: [turbofan] [deoptimizer] Support inlining of ES6 tail calls. · 209c2152
      mbrandy authored 
      Port c29a4560

Original commit message:
    In case when F was called with incompatible number of arguments (and therefore
    the arguments adator frame was created), F inlines a tail call of G which then
    deopts the deoptimizer should also remove the arguments adaptor frame for F.

    This CL adds required machinery to the deoptimizer.

      PPC: [runtime] Unify and simplify how frames are marked · 4445c095
      mbrandy authored 
      Port 9dcd0857

Original commit message:
    Before this CL, various code stubs used different techniques
    for marking their frames to enable stack-crawling and other
    access to data in the frame. All of them were based on a abuse
    of the "standard" frame representation, e.g. storing the a
    context pointer immediately below the frame's fp, and a
    function pointer after that. Although functional, this approach
    tends to make stubs and builtins do an awkward, unnecessary
    dance to appear like standard frames, even if they have
    nothing to do with JavaScript execution.

    This CL attempts to improve this by:

    * Ensuring that there are only two fundamentally different
      types of frames, a "standard" frame and a "typed" frame.
      Standard frames, as before, contain both a context and
      function pointer. Typed frames contain only a minimum
      of a smi marker in the position immediately below the fp
      where the context is in standard frames.
    * Only interpreted, full codegen, and optimized Crankshaft and
      TurboFan JavaScript frames use the "standard" format. All
      other frames use the type frame format with an explicit
      marker.
    * Typed frames can contain one or more values below the
      type marker. There is new magic macro machinery in
      frames.h that simplifies defining the offsets of these fields
      in typed frames.
    * A new flag in the CallDescriptor enables specifying whether
      a frame is a standard frame or a typed frame. Secondary
      register location spilling is now only enabled for standard
      frames.
    * A zillion places in the code have been updated to deal with
      the fact that most code stubs and internal frames use the
      typed frame format. This includes changes in the
      deoptimizer, debugger, and liveedit.
    * StandardFrameConstants::kMarkerOffset is deprecated,
      (CommonFrameConstants::kContextOrFrameTypeOffset
      and StandardFrameConstants::kFrameOffset are now used
      in its stead).
