To enter break point, you need to run a m68k program in Macintosh guest OS. The program
executes a new emul_op instruction 0x7138. The program will be provided
in cxmon/utils folder in a separate commit. Once emulation is suspended,
you can enter below new cxmon command to manipluate break points:
ba [address] Add a break point
br [breakpoints#] Remove a break point. If # is 0, remove all break points.
bd [breakpoints#] Disable a break point. If # is 0, disable all break points.
be [breakpoints#] Enable a break point. If # is 0, enable all break points.
bi List all break points
bs "file" Save all break points to a file
bl "file" Load break points from a file
Once emulation PC reach break point address, it automatically suspends
and traps into cxmon.

On those systems, it's really hard to get high resolution timings and the
system oftens fails to honour a timeout in less than 20 ms. The idea here
is to have an average m68k instruction count (countdown quantum) that
triggers real interrupt checks. The quantum is calibrated every 10 ticks
and has a 1000 Hz resolution on average.
instruction handler by hand and make sure to save %ebp too
- Really merge cpu core with uae-0.8.21:
- Trace mode fixes (Bernd Roesch & Bernd Schmidt)
- Reintegrate PTEST and PFLUSH instructions back as no-ops
possible
- rom_patches.cpp: check for double PACK 4 resources; if only one is found,
assume that the ROM requires an FPU and issue a warning if FPU emulation
is turned off
- UAE CPU opcode routines no longer return the cycle count
- main_unix.cpp: pressing Ctrl-C dumps the UAE CPU state before entering mon
- sys_unix.cpp: under Linux, partition sizes are read with BLKGETSIZE instead
of llseek()
