8ddf749ed5 fix vm_do_read_memory_8() 2003-11-04 15:00:02 +00:00

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.

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.

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.

d766049d59 - enable multicore cpu emulation with ASYNC_IRQ 
- move atomic_* operations to main_unix so that they could use spinlocks or
  other platform-specific locking mechanisms

9057fda327 - FreeBSD/i386 sigcontext subterfuge support for instruction skipper 
- NetBSD/alpha support from Boehm GC
- NetBSD/i386 won't work in sigcontext subterfuge mode unless instruction
  is decoded more accurately to compute the effective address. Also note
  that NetBSD 1.6 does not support siginfo_t yet.

309c2f0bd5 Add "jitblacklist" prefs item so that opcodes ranges could be excluded for 
translation. This should help debugging of (badly) translated code.

Usage: jitblacklist xxxx(-yyyy)?(;xxxx(-yyyy)?)*
where xxxx/yyyy are hexadecimal numbers

c04603adce Add hacks to disable "floppy" & "serial[ab]" entries that would cause 
Basilisk II to hang on MacOS X as an X11 build. I am not sure this is
supposed to work in an Aqua build so I leave that enable there, assuming
<AvailabilityMacros.h> is included somehow, thus defining MAC_OS_X_VERSION_*
and friends.

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.

b66f5972f9 Make sure a 32-bit B2/JIT works reasonnably well on AMD64 too. This implies 
to force RAMBaseHost < 0x80000000. This is empirically determined to work on
Linux/x86 and Linux/amd64.
