 349         * interp.c (hash): Update to be more accurate.
 350         (lookup_hash): Call hash rather than computing the hash
 351         code here.
 352         (do_format_1_2): Handle format 1 and format 2 instructions.
 353         Get operands correctly and call the target function.
 354         (do_format_6): Get operands correctly and call the target
 355         function.
 356         (do_formats_9_10): Rough cut so shift ops will work.
 357         (sim_resume): Tweak to deal with format 1 and format 2
 358         handling in a single funtion.  Don't update the PC
 359         for format 3 insns.  Fix typos.
 360         * simops.c: Slightly reorganize.  Add condition code handling
 361         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
 362         and "not" instructions.
 363         * v850_sim.h (reg_t): Registers are 32bits.
 364         (_state): The V850 has 32 general registers.  Add a 32bit
 365         psw and pc register too.  Add accessor macros
 366
 367         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
 368         changes from the d10v simulator.
 369
 370         * simops.c: Add shift support.
 371
 372         * simops.c: Add multiply & divide support.  Abort for system
 373         instructions.
 374
 375         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
 376         and subr.  No condition codes yet.
