7e20a8d205 - Add support for FLIGHT_RECORDER with predecode cache
- Always enable predecode cache & flight recorder for now

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.

1012da75dd - Cleanups & make sure PPC emulator config is setup in sysdeps.h
- Log r24 in SheepShaver mode as this represents the 68k emulator PC

974ebd5d91 - Add checks against ROM patches space
- Make sure to also load the floppy disk driver with Gossamer ROMs so
  that exfs feature can work too

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.

b8b139faf2 - Share EmulatorData & KernelData struct definitions
- Introduce new SheepShaver data area for alternate stacks, thunks, etc.
- Experimental asynchronous interrupts handling. This improves performance
  by 30% but some (rare) lockups may occur. To be debugged!

a48a804c15 New SIGSEGV API so that skip-instruction requests are more explicit. Yes,
that's api change, but that's cooler now for SheepShaver. ;-)

of fake SCSIGlobals (disabled for now). Switch back to mono core emulation
until things are debugged enough. Implement get_resource() et al.
