591 instruction is encountered. Very crude support for
592 emulated syscalls (trap 0).
593 * v850_sim.h: Include "callback.h" and declare

652 "di", and "ei" instructions correctly.

672 (do_formats_9_10): Rough cut so shift ops will work.
673 (sim_resume): Tweak to deal with format 1 and format 2
674 handling in a single funtion. Don't update the PC
675 for format 3 insns. Fix typos.

677 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
678 and "not" instructions.
679 * v850_sim.h (reg_t): Registers are 32bits.
680 (_state): The V850 has 32 general registers. Add a 32bit
681 psw and pc register too. Add accessor macros

684 changes from the d10v simulator.
686 * simops.c: Add shift support.
688 * simops.c: Add multiply & divide support. Abort for system
691 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
