55f5e3a41b Fix CR save/restore in EmulOp thunk. I don't know what it fixes for real 
but that was definitely wrong to only preserve CR2 there.

where InterruptFlags is 0.

9019e71cfc Preserve all necessary registers on interrupt, thus also permitting nested 
interrupts to occur. SheepShaver locks should now be reduced.

114f5ff6c7 Use BUILD_SHEEPSHAVER_PROCEDURE to allocate static procedures into the 
SheepShaver globals. Fix build of sheepshaver_glue.cpp without JIT.

3ace37f4eb Implement Direct Addressing mode similarly to Basilisk II. This is to get 
SheepShaver working on OSes that don't support maipping of Low Memory globals
at 0x00000000, e.g. Windows.

58e74f3ca0 Enable ethernet everywhere, several users got it to work. Hangs may be 
unrelated to ethernet code anyway and ethernet driver should be endian
safe nowadays.

3e5c98c7d4 Performance of VOSF is heuristically determined at run-time, so have to 
initialize SIGSEGV handlers early, as in Basilisk II. Besides, also add
missing call to vm_init() in case host system doesn't have MAP_ANON.

0dcb2b4516 SDL support in SheepShaver too, though it doesn't work in native mode 
on Linux/ppc as libSDL is pulling in libpthread which conflicts with
our sheepthreads.

e0a76f9e38 Don't handle XLM_IRQ_NEST atomically in emulated mode. That's useless since 
this variable is modified only within a single thread and interrupts are
not handled asynchronously.

070ac7079f Always handle interrupt even if InterruptFlags == 0, though it should not 
really happen in practise.

301d3a3192 STATS: Account for all interrupts, but still count native interrupts. It 
turns out that for a regular bootup sequence to the Finder, less than 30%
interrupts triggered were in native mode.

Default EMUL_TIME_STATS to 0, end user probably doesn't want garbage to
be printed to his console.

c3f2342f47 Make NativeOp() handler a sheepshaver_cpu handler, thus getting rid of ugly 
GPR macro definition.

Make the JIT engine somewhat reentrant. This brings a massive performance
boost for applications that cause many Execute68k(). e.g. audio in PlayerPRO.

ba7bfc478e Extend NativeOp count to 64 (6-bit value), aka fix NATIVE_FILLRECT opcpdes. 
Translate NQD_{bitblt,fillrect,invrect} to direct native calls.

8b40a7e721 NQD: use ReadMacInt*() and WriteMacInt*() accessors, i.e. code should now 
be little-endian and 64-bit safe.

10b9ab2c34 Generate PowerPC code wrapping GetResource() replacements. That way, it's 
a normal PPC function invocation that can be JIT compiled to native code
instead of nesting execute() calls which may lead to use the interpreter
(this took around 11% of total execution time on boot, downto 3%).

Also, optimize some SheepShaver EmulOps and actually report non-CTI.

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.

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.

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

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.
