      Re-reland: Remove register index/code indirection · 5cf1c0bc
      danno authored
      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.

      MIPS64: Fix hidden bug in relocations for j and jal. · 38501327
      dusan.milosavljevic authored
      Introduce new mechanism for relocating j/jal.
      
      Resolves flaky failures of mozilla regress tests.
      
      Additionally:
      
      - internal encoded references are not relocated during code generation phase.
      - remove asserts from j and jal which are not
      valid because addresses are not final and valid in code generation phase.
      
      TEST=mozilla/js1_5/Regress/regress-280769-2, regress-367561-01,
           mozilla/ecma_3/Statements/regress-444979

      Debugger: use debug break slot to break on call. · 8965b683
      yangguo authored
      Break point at calls are currently set via IC. To change this, we
      need to set debug break slots instead. We also need to distinguish
      those debug break slots as calls to support step-in.
      
      To implement this, we add a data field to debug break reloc info to
      indicate non-call debug breaks or in case of call debug breaks, the
      number of arguments. We can later use this to find the callee on the
      evaluation stack in Debug::PrepareStep.

      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.
