Great PowerPC emulation code resynchronisation and improvments:
- 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.
