      [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.

      [builtins] Introduce a builtin for Abort(). · 9be015a2
      ahaas authored 
      Calling Runtime::kAbort through a builtin instead of the c-entry stub
will allow to generate the call in a background thread, because a
builtin provides its own handle, whereas a code stub does not.

@v8-mips-ports: Could you take a special look at the padding that is
done in MacroAssembler::Abort()?

      [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.

      [builtins] Add receiver to builtin exit frames · f59a2335
      jgruber authored 
      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.

BUG=v8:4815

      Reland [heap] Avoid the use of cells to point from code to new-space objects. · 5e058540
      ahaas authored 
      The reason for reverting is: This breaks gc-stress bot:
https://chromegw.corp.google.com/i/client.v8/builders/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot

Abortion of compaction could cause duplicate entries in the typed-old-to-new remembered set. These duplicates could cause a DCHECK to trigger which checks that slots recorded in the remembered set never point to to-space. This reland-CL allows duplicates in the remembered set by removing the DCHECK, and additionally clears entries in the remembered set if objects are moved.

Original issue's description:

Cells were needed originally because there was no typed remembered set to
record direct pointers from code space to new space. A previous
CL (https://codereview.chromium.org/2003553002/) already introduced
the remembered set, this CL uses it.

This CL
* stores direct pointers in code objects, even if the target is in new space,
* records the slot of the pointer in typed-old-to-new remembered set,
* adds a list which stores weak code-to-new-space references,
* adds a test to test-heap.cc for weak code-to-new-space references,
* removes prints in tail-call-megatest.js
