      [stubs] Port StoreTransitionStub and ElementsTransitionAndStoreStub to TurboFan. · 130d9893
      ishell authored 
      This CL also cleans up related interface descriptors:
1) unused StoreTransitionDescriptor is removed and VectorStoreTransitionDescriptor is
renamed to StoreTransitionDescriptor.
2) on ia32/x87 architectures slot and vector are passed on the stack (dispatcher/handlers
cleanup will be addressed in a separate CL).

These two stub ports have to be combined in one CL because:
1) without changing the StoreTransitionDescriptor TF was not able to compile them
on ia32/x87 (because of lack of registers),
2) it was not possible to change the descriptor first because Crankshaft was not able
to deal with the stack allocated parameters in case of a stub failure.

      Move kMaxRegularHeapObjectSize into globals · 059b5643
      mlippautz authored 
      This way we avoid the cyclic dependency between objects.h and heap.h and still
have one definition. Add a static assert that this size is indeed smaller than
the payload of a page.

Follow ups can finally remove the dependency on spaces.h for all heap.h users.

      [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.

      PPC/s390: [stubs] Port CreateWeakCellStub to turbofan · ddea5a67
      bjaideep authored 
      Port 7f1fa30e

Original commit message:

    In the process also inline the stub into the appropriate interpreter bytecode
    handler and make sure that the context register is preserved in hand-written
    assembly code that calls the stub and expects the context register to be
    preserved.

      [turbofan] Add support for eager/soft deoptimization reasons. · db635d5b
      bmeurer authored 
      So far TurboFan wasn't adding the deoptimization reasons for eager/soft
deoptimization exits that can be used by either the DevTools profiler or
the --trace-deopt flag. This adds basic support for deopt reasons on
Deoptimize, DeoptimizeIf and DeoptimizeUnless nodes and threads through
the reasons to the code generation.

Also moves the DeoptReason to it's own file (to resolve include cycles)
and drops unused reasons.

      PPC/s390: [builtins] Fix MathMaxMin on arm and arm64 · 32e843df
      bjaideep authored 
      Port b86ac0e0

Original commit message:

    Both of these were broken in different ways:
    * On arm, the loop counter was passed as argc on the stack.
    * On arm64, we passed argc + 1 instead of argc.

    The result in both cases was an incorrect receiver for the builtin frame
    when generating stack traces.

      PPC/s390: [builtins] Add receiver to builtin exit frames · 96ebd756
      bjaideep authored 
      Port f59a2335

Original commit message:

    Stack trace generation requires access to the receiver; and while the
    receiver is already on the stack, we cannot determine its position
    during stack trace generation (it's stored in argv[0], and argc is only
    stored in a callee-saved register).

    This patch grants access to the receiver by pushing argc onto builtin
    exit frames as an extra argument. Compared to simply pushing the
    receiver, this requires an additional dereference during stack trace
    generation, but one fewer during builtin calls.
