2007-03-31Support for PowerPC BookE exception model.j_mayer
No need to requeue timer exceptions. Fix nip saving for 64 bits PowerPC. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2556 c046a42c-6fe2-441c-8c8c-71466251a162

2007-03-31As embedded PowerPC TLB model is very different from PowerPC 6xx ones,j_mayer
define ppc_tlb_t as an union of the two. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2553 c046a42c-6fe2-441c-8c8c-71466251a162
2007-03-30Fix rfi instruction: do not depend on current execution modej_mayer
but on the execution mode that will be effective after the return. Add rfci, rfdi and rfmci for BookE PowerPC. Extend mfdcr / mtdcr and implement mfdrcx / mtdcrx. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2544 c046a42c-6fe2-441c-8c8c-71466251a162
2007-03-30Fix / update PowerPC BookE definitions.j_mayer

2007-03-30New model for PowerPC CPU hardware interrupt events:j_mayer
move all PowerPC specific code into target-ppc/helper.c to avoid polluting the common code in cpu-exec.c. This makes implementation of new features (ie embedded PowerPC timers, critical interrupts, ...) easier. This also avoid hardcoding the IRQ callback in the OpenPIC controller, making it more easily reusable and allowing cascading. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2542 c046a42c-6fe2-441c-8c8c-71466251a162

2007-03-23Fix debug printf: we need different macros for target_ulong printsj_mayer

2007-03-22PowerPC improvments:j_mayer
- add missing 64 bits rotate instructions - safely define TARGET_PPCSPE when 64 bits registers are used a separate target will be needed to use it in 32 bits mode on 32 bits hosts. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2527 c046a42c-6fe2-441c-8c8c-71466251a162
2007-03-22PowerPC bugfixes:j_mayer
- must clear carry bit when doing addic with a zero immediate value - fix missing RETURN in micro-operation that would lead to random failures and crashes - add USE_PRECISE_EMULATION compilation-time option to choose between getting exact floating point results and fast but less accurate computation. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2526 c046a42c-6fe2-441c-8c8c-71466251a162

2007-03-17Make it safe to use 64 bits GPR and/or 64 bits host registers.j_mayer
For "symetry", add 64 bits versions of all modified functions. As a side effect, add a lot of code provision for PowerPC 64 support. Move overflow and carry checks in common routines for simple cases. Add isel and popcntb instructions from PowerPC 2.03 specification. Remove remaining micro-operations helpers prototypes from op.c. Fix XER_BC field to be 7 bits long. Add power management support for PowerPC 603 & 604. Fix compilation warnings. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2482 c046a42c-6fe2-441c-8c8c-71466251a162
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
