aee3e05e4b The JIT should work now but there is an extra bottleneck causing it to 
not match Kheperix speeds while executing Linux/ppc binaries.

Fix x86 DYNGEN_OP_FLAGS settings. Only allocate translation cache in .data
on PPC since x86 can do jumps anywhere.

73d51962f6 Merge in-progress PowerPC "JIT1" engine for AMD64, IA-32, PPC. 
The merge probably got wrong as there are some problems probably due to the
experiment begining with CR deferred evaluation. With nbench/ppc, performance
improvement was around 2x. With nbench on x86, performance improvement was
around 4x on average.

Incompatible change: instr_info_t has a new field in the middle. But since
insertion of PPC_I(XXX) identifiers is auto-generated, there is no problem.
 2003-11-24 23:45:52 +00:00

7968a20100 Handle "JIT1" engine but disable it for now since there are some problems

b66d8ef433 Fix "ignoresegv" case to actually skip the faulty instruction. Merge 
conditions to skip instruction on SIGSEGVfrom PowerPC native mode. The
instruction skipper takes care to set the output register to 0.

0260210ddf - XLM_IRQ_NEST is always in native byte order format since any write to 
this variable go through {Enable,Disable}Interrupt().
- Add Ether thunks but only for WORDS_BIGENDIAN case since we do need more
complicated translation functions.

cd86ff9e94 - Start emulating the FPSCR. Fix mtfsf, mffs. 
- Implement mftbr so that MacOS can fully boot with extensions. However,
  using clock() is probably not the right solution. Patching UpTime from
  DriverServicesLib et al. may be a better solution.

30bd089279 PowerPC floating-point registers are now an union of uint64 & double. This

a42281aad1 Implement partial block cache invalidation. Rewrite core cached blocks 
execution loop with a Duff's device. Gather some predecode time statistics.
This shows that only around 2% of total emulation time is spent for
predecoding the instructions.

f0ea192460 Optimized pointers to non virtual member functions. This reduces space 
and overhead since runtime checks are eliminated. Actually, it yields
up to 10% performance improvement with specialized decoders.

gbeauche
89d0f9ca29 Integrate spcflags handling code to kpx_cpu core. We can also remove 
oldish EXEC_RETURN handling with a throw/catch mechanism since we
do have a dependency on extra conditions (invalidated cache) that
prevents fast execution loops.

9ce43c6cf3 Fix ASYNC_IRQ build but locks may still happen. Note that with a predecode 
cache, checking for pending interrupts may not be the bottle neck nowadays.
 2003-10-26 14:16:40 +00:00
gbeauche
60d34a6816 Rewrite interrupts handling code so that the emulator can work with a 
predecode cache. This implies to run in interpreted mode only while
processing EmulOps or other native (nested) runs.

Note that the FLIGHT_RECORDER with a predecode cache gets slower than
without caching at all.

ebb67f0421 - Minor optimization to execute_ppc() as we apparently don't need to move 
target PC into CTR.
- Fix breakage introduced during little endian fixing. We now assume that
  MacOS doesn't rely on any PPC register that may have been saved on top
  of it stack. i.e. register state is saved onto native stack.
