2007-03-07Great PowerPC emulation code resynchronisation and improvments:j_mayer
- 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. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2473 c046a42c-6fe2-441c-8c8c-71466251a162
