      Great PowerPC emulation code resynchronisation and improvments: · 76a66253
      j_mayer 提交于
      - Add status file to make regression tracking easier
      - Move all micro-operations helpers definitions into a separate header:
        should never be seen outside of op.c
      - Update copyrights
      - Add new / missing PowerPC CPU definitions
      - Add definitions for PowerPC BookE
      - Add support for PowerPC 6xx/7xx software driven TLBs
        Allow use of PowerPC 603 as an example
      - Add preliminary code for POWER, POWER2, PowerPC 403, 405, 440, 601, 602
        and BookE support
      - Avoid compiling priviledged only resources support for user-mode emulation
      - Remove unused helpers / micro-ops / dead code
      - Add instructions usage statistics dump: useful to figure which instructions
        need strong optimizations.
      - Micro-operation fixes:
        * add missing RETURN in some micro-ops
        * fix prototypes
        * use softfloat routines for all floating-point operations
        * fix tlbie instruction
        * move some huge micro-operations into helpers
      - emulation fixes:
        * fix inverted opcodes for fcmpo / fcmpu
        * condition register update is always to be done after the whole
          instruction has completed
        * add missing NIP updates when calling helpers that may generate an
          exception
      - optimizations and improvments:
        * optimize very often used instructions (li, mr, rlwixx...)
        * remove specific micro-ops for rarely used instructions
        * add routines for addresses computations to avoid bugs due to multiple
          different implementations
        * fix TB linking: do not reset T0 at the end of every TB.
