      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.

      PPC: Switch full-codegen from StackHandlers to handler table. · 918ec32d
      michael_dawson authored 
      Port 38a719f9

Original commit message:
This switches full-codegen to no longer push and pop StackHandler
markers onto the operand stack, but relies on a range-based handler
table instead. We only use StackHandlers in JSEntryStubs to mark the
transition from C to JS code.

Note that this makes deoptimization and OSR from within any try-block
work out of the box, makes the non-exception paths faster and should
overall be neutral on the memory footprint (pros).

On the other hand it makes the exception paths slower and actually
throwing and exception more expensive (cons).

      Contribution of PowerPC port (continuation of 422063005) - uplevel · 45e4a789
      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 as of today.

We had to exclude the test test-serialize/SerializeInternalReference
until we agree on the right way to add those changes for PPC as
outlined in the description in the google doc provided earlier.

We also had to exclude a couple of other tests due to new
failures seen since the last uplevel.  We excluded as opposed
to waiting until we could investigate to maximize the chance
of getting PPC compiling in the google repos before new
breaking changes are made.

I'll note that before applying any of our changes the
mozilla part of quickcheck was already broken when using
the lastest repo content so I had to run without that

      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) - PPC dir update · 308d913a
      michael_dawson authored 
      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.

      [Arm]: Enable use of extended out-of-line constant pool for Arm. · 40af47d4
      rmcilroy@chromium.org authored 
       - Adds support to the Arm assembler to use extended constant pools.
 - Update (set_)target_address_at to support extended constant pool load
   updates.
 - Replace Operand::is_single_instruction with Operand::instructions_required
   Due to the fact that different constant pool load types require different
   numbers of instructions.
 - Various cleanups of ConstantPoolBuilder to cleaner integration of the
   extended constant pool building.
 - Update GetRelocatedValue such that offsets to both map_check and bool_load
   are explicitly provided, rather than location of bool_load being inferred
   based on map_check, since the code inbetween is no longer of a predictable
   size.
 - Update MacroAssembler::GetRelocatedValueLocation() to add support for
   getting a value from an extended constant pool entry.
 - Update Debug::SetAfterBreakTarget() to use target_address_from_return_address
   when checking for debug breaks at constant pool load points.
 - Change ConstantPoolIterateBody to iterate over both heap and code pointer in
   the small section before moving onto the extended section, to work around the
   requirement of the serializer that pointers are iterated in-order.
 - Increase old_pointer_space SizeOfFirstPage() to offset the fact that constant
   pools are now in the old pointer space (rather than code).
