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.
