      X87: Debugger: use debug break slot to break on call. · a5458c92
      chunyang.dai authored 
      port 8965b683 (r29561)

original commit message:

    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.

      X87: [turbofan] Add TruncationMode for TruncateFloat64ToInt32. · a02e644c
      chunyang.dai authored 
      port 4b38c158 (r29527).

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.

      X87: Reland: Add unoptimized/optimized variants of MathFloor TF code stub · 1b20d505
      chunyang.dai authored 
      port 737b8573 (r29539)

original commit message:

    - Add a TurboFanIC class, derived from TurboFanCodeStub, that
      automatically distinguishes between versions of the IC called from
      optimized and unoptimized code.
    - Add appropriate InterfaceDescriptors for both the versions of the
      stub called from unoptimized and optimized code
    - Change the MathFloor TF stub generator to output either the
      for-optimized or for-unoptimized version based on the minor_key
      parameter.
