      [ic] Properly integrate the CallIC into Ignition. · ee350c31
      Benedikt Meurer authored 
      Drop the deprecated CallConstructStub and remove the use of CallICStub
from fullcodegen, since that feedback is unused completely every since
Crankshaft got removed, thus we can safely unlink all the CallIC stuff
from fullcodegen nowadays, and completely nuke the CallICStub and the
CallICTrampolineStub now (we can also transitively nuke the unused
CreateAllocationSiteStub and CreateWeakCellStub).

Instead the CallIC logic is integrated into Ignition now, and part of
the bytecode handlers for [[Call]] and [[Construct]]. There's still some
follow-up cleanup with the way the Array constructor feedback is
integrated, but that's way easier now.

      Instead of auto-generating the Name() convenience accessor, use a macro to
avoid wasting code space.

  BUILTIN_CODE(isolate, Name)

expands to

  isolate->builtins()->builtin_handle(Builtins::kName);

This reduces the size of libv8.so by 134,752 bytes on a x64 release build.

      PPC/s390: Switch JSFunction::code to be a tagged value. · 9836cdb1
      Jaideep Bajwa authored 
      Port 4e207a42

Original Commit Message:

    This switches the "code entry" field on JSFunction to no longer be an
    inner pointer into a Code object (i.e. to the start of the instruction
    stream), but a properly tagged pointer instead.

    Motivation behind this is the ability to treat this field regularly as
    part of escape analysis in the optimizing compiler. Also simplifies the
    object visitation for JSFunction objects.

      PPC/s390: [turbofan] Widen the fast-path for JSCreateArray. · 00a8ab2e
      Jaideep Bajwa authored 
      Port 1edb46cc

Original Commit Message:

    This improves the general Array constructor call performance (w/o
    usable AllocationSite feedback) in TurboFan by ~2x, i.e. for example
    invoking the Array constructor like this

      var a = Array.call(undefined, n);

    instead of

      var a = Array(n);

    such that the CallIC doesn't know that it's eventually calling the
    Array constructor.

    It also thus changes the single argument Array constructor to always
    return holey arrays. Previously the single argument case for the Array
    constructor was somehow trying to dynamically detect 0 and in that case
    returned a packed array instead of a holey one. That adds quite a lot
    of churn, and doesn't seem to be very useful, especially since this
    might lead to unnecessary feedback pollution later.
