542 (do_formats_9_10): Rough cut so shift ops will work.
543 (sim_resume): Tweak to deal with format 1 and format 2
544 handling in a single funtion. Don't update the PC
545 for format 3 insns. Fix typos.
546 * simops.c: Slightly reorganize. Add condition code handling
547 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
548 and "not" instructions.
549 * v850_sim.h (reg_t): Registers are 32bits.
550 (_state): The V850 has 32 general registers. Add a 32bit
551 psw and pc register too. Add accessor macros
553 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
554 changes from the d10v simulator.
556 * simops.c: Add shift support.
558 * simops.c: Add multiply & divide support. Abort for system
561 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
562 and subr. No condition codes yet.
