This series is the first series that will allow
to introduce supervisor mode and execute
privileged instructions.
Some of these patches are only cleanup:
sync CC_OP before gen_jmp_tb()
fix gen_get_ccr()
softmmu cleanup
add CPU_LOG_INT trace
use insn_pc to generate instruction fault address
move CCR/SR functions
fix m68k_cpu_dump_state()
We also fix a problem with linux-user mode,
where the State Register is not updated with
the CCR value (found while testing "chk/chk2"
using signal()):
correctly manage SR in context
We introduce some new non privileged instructions:
add chk and chk2
add move16
move16 is used by the kernel when it is compiled only for
68040 (it's a 68040 only instruction).
We add some trivial privileged instructions (most are empty):
add cpush/cinv
add reset
implement fsave/frestore
And finally, we add the privileged instructions to
modify the state register, the Interrupt Stack
Pointer and the 680x0 stack frame formats:
add 680x0 "move to SR" instruction
add andi/ori/eori to SR/CCR
add the Interrupt Stack Pointer
manage 680x0 stack frames
The next series will introduce the MC68040 MMU.
v6: introduce cpu_m68k_set_sr() to set SR instead
of calling helper_set_sr().
update SR with the content of CCR in the logs
use helpers as suggested by Richard for chk/chk2
split move16 in two functions
use cpu_m68k_set_sr() to set SR in GDB stub and in m68k_cpu_reset()
v5: it is in fact v1, there is no previous version.
I've messed up with git-publish on an older branch without checking the
subject prefix. Sorry...
