      PPC: Remove register index/code indirection · f53fda63
      mbrandy authored 
      Port 5cf1c0bc

Original commit message:
    Previous to this patch, both the lithium and TurboFan register
    allocators tracked allocated registers by "indices", rather than
    the register codes used elsewhere in the runtime. This patch
    ensures that codes are used everywhere, and in the process cleans
    up a bunch of redundant code and adds more structure to how the
    set of allocatable registers is defined.

    Some highlights of changes:

    * TurboFan's RegisterConfiguration class moved to V8's top level
      so that it can be shared with Crankshaft.
    * Various "ToAllocationIndex" and related methods removed.
    * Code that can be easily shared between Register classes on
      different platforms is now shared.
    * The list of allocatable registers on each platform is declared
      as a list rather than implicitly via the register index <->
      code mapping.

      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.

      Contribution of PowerPC port (continuation of 422063005) - currency · a3465838
      michael_dawson authored 
      Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. This patch updates the ppc directories
to make them current with changes in common code, removes the
optimization to use the ool constant pool, and excludes tests that
don't pass under the ppc simulator given a 240s timeout.

Subsequent patches will cover:
   - remaining optimizations for PPC
   - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX)
   - incremental updates required to ppc directories due to platform specific changes made
    in google repos while we complete the above steps.

      Contribution of PowerPC port (continuation of 422063005, 817143002 and 866843003)
This patch brings the ppc directories up to date with our repo. We have
removed 5 individual optimizations which require changes in both the ppc and common
directories so they can be more easily reviewed on their own in subsequent patches.

Subsequent patches will cover:
- individual optimizations for PPC (5)
- remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available
for AIX)
- incremental updates required to ppc directories due to platform specific changes
made in google repos while we complete the above steps.

With the update there are still some timeouts seen when run in simulated mode which
may be a result of the missing optimizations.  Once we have the optimizations in
we will review the simulation results and address/exclude tests as necessary so that
the simulated runs are clean.

      The IC exposes a register definition. · addd35df
      mvstanton@chromium.org authored 
      Centralize a register definition in an IC that provides:
1) symbolic names for the register (like, edx == receiver)
2) defines ordering when passed on the stack

Code that implements or uses the IC should use this definition instead of "knowing" what the registers are. Or at least have the definition to validate it's assumptions.

As a side effect of avoiding runtime static initializers (enforced by tools/check-static-initializers.sh, neat), I gave ownership of the registers array to CodeStubInterfaceDescriptor. This prompted a cleanup of that struct.
