      X87: Debugger: prepare code for debugging on a per-function basis. · 65f18c9d
      chunyang.dai authored 
      port 35c28ce0 (r29758).

original commit message:

    Prior to this patch, we enter a global debug mode whenever a break point
    is set. By entering this mode, all code is deoptimized and activated
    frames are recompiled and redirected to newly compiled debug code.

    After this patch, we only deoptimize/redirect for functions we want to
    debug. Trigger for this is Debug::EnsureDebugInfo, and having DebugInfo
    object attached to the SFI prevents optimization/inlining.

    The result is that we can have optimized code for functions without break
    points alongside functions that do have break points, which are not
    optimized.

      - split relocation info for debug break slots for
  - calls (with call arguments count as data)
  - construct calls
  - normal slots
- renamed DEBUG_BREAK into DEBUGGER_STATEMENT
- removed unused IC state for Debug stubs

      Add support for Embedded Constant Pools for PPC and Arm · eac7f046
      mbrandy authored 
      Embed constant pools within their corresponding Code
objects.

This removes support for out-of-line constant pools in favor
of the new approach -- the main advantage being that it
eliminates the need to allocate and manage separate constant
pool array objects.

Currently supported on PPC and ARM.  Enabled by default on
PPC only.

This yields a 6% improvment in Octane on PPC64.

      Decouple CpuFeatures from serializer state. · fe243379
      yangguo@chromium.org authored 
      Traditionally, we cross compile a snapshot iff the serializer is enabled.
This will change in the future.

Changes:
 - CpuFeatures probing is done once per process, depending on whether we
   cross compile.
 - CpuFeatures are consolidated into the platform-independent assembler.h
   as much as possible.
 - FLAG_enable_<feature> will only be checked at probing time (already the
   case for ARM).
 - The serializer state is cached by the MacroAssembler.
 - PlatformFeatureScope is no longer necessary.
 - CPUFeature enum values no longer map to CPUID bit fields.

      Special case the recording of constant pool entries in the slot buffer. · 9cfd807c
      rmcilroy@chromium.org authored 
      This CL enables RelocInfo pointers which live in the constant pool to be treated
as normal pointers by the slot buffer, avoiding the requirement of creating fake
RelocInfo objects during UpdateSlots() in order to update these slots.  This
is possible because constant pool entries are just pointers and don't require
the RelocInfo machinary to be updated.

EmbeddedObject constant pool entries can be added untyped to the slot buffer,
while code targets are still typed in order to correctly update the target
address based on the relocated code object.

Note: this is required in order to enable OOL constant pool support on Arm, but
should be benifitial for the current inline constant pool used by Arm code.
