      Add CompileInfo::GetDebugName() · 53ac9fe8
      rmcilroy authored 
      Replaces all instances of the code which computed the debug
name of a stub or function with calls to CompileInfo::GetDebugName instead.

Also:
  - Removes useless parameter on CodeStub::GetMajorName
  - Removes FakeStubForTesting since it is no longer required
  - Adds CompileInfo::ShouldEnsureSpaceForLazyDeopt() to replace unclear calls to IsStub().

      PPC: [interpreter] Add basic framework for bytecode handler code generation. · 3144d1f1
      mbrandy authored 
      Port 7877c4e0

Original commit message:
    Adds basic support for generation of interpreter bytecode handler code
    snippets. The InterpreterAssembler class exposes a set of low level,
    interpreter specific operations which can be used to build a Turbofan
    graph. The Interpreter class generates a bytecode handler snippet for
    each bytecode by assembling operations using an InterpreterAssembler.

    Currently only two simple bytecodes are supported: LoadLiteral0 and Return.

      PPC: [turbofan] Add TruncationMode for TruncateFloat64ToInt32. · 2798e118
      mbrandy authored 
      Port 4b38c158

Original commit message:
    We actually need round to zero truncation to implement the counterpart
    of LDoubleToI in TurboFan, which tries to convert a double to an integer
    as required for keyed load/store optimizations.

    Drive-by-cleanup: Reduce some code duplication in the InstructionSelector
    implementations.

      PPC: [turbofan] Enable tail calls for %_CallRuntime. · 69247871
      mbrandy authored 
      Port 1fa4285e

Original commit message:
    This involves:
    - Enabling the tail call optimization reducer in all cases.
    - Adding an addition flag to CallFunctionParameters to mark call sites
      that can be tail-called enabled.
    - Only set the tail-call flag for %_CallFunction.

      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.

      [turbofan] Introduce prediction for exception handlers. · d8b94f34
      mstarzinger authored 
      This introduces a conservative prediction for each exception handler
whether it will locally catch an exception or re-throw it to outside
the code bondaries. It will allow for a more intuitive prediction of
whether an exception is considered "caught" or "uncaught".

      PPC: [turbofan] Fix tail call optimization. · 38f7ccba
      mbrandy authored 
      Port d21de2a4

Original commit message:
Tail calls are matched on the graph, with a dedicated tail call
optimization that is actually testable. The instruction selection can
still fall back to a regular if the platform constraints don't allow to
emit a tail call (i.e. the return locations of caller and callee differ
or the callee takes non-register parameters, which is a restriction that
will be removed in the future).

Also explicitly limit tail call optimization to stubs for now and drop
the global flag.

      Detect simple tail calls · 4b122b75
      svenpanne authored 
      This CL contains the first steps towards tail call optimization:

  * Structurally detect tail calls during instruction selection,
    looking for special return/call combinations.

  * Added new architecture-specific instructions for tail calls which
    jump instead of call and take care of frame adjustment.

  * Moved some code around.

Currently we restrict tail calls to callees which only use registers
for arguments/return value and to call sites which are explicitly
marked as being OK for tail calls. This excludes, among other things,
call sites in sloppy JS functions and our IC machinery (both need in
general to be able to access the caller's frame).

All this is behind a flag --turbo-tail-calls, which is currently off
by default, so it can easily be toggled.
