374101ee9e Make DR Cache executable by default in native PowerPC mode. 2004-05-31 10:55:42 +00:00

a533a9c455 Enable DR emulator with OldWorld ROMs too. It turned out that translated 
code was also trying to access Serial memory.

Note however that I noticed some rare crashes with the DR emulator.
Probably caused by nested runs from EmulOps? We'd really want a native
68k emulator too for Execute68k() things.

b0aae35951 Do FOLLOW_CONST_JUMPS for bcl 20,BI,TARGET branches too, since that's an

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

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.
