 346         * simops.c: Handle "jarl" and "jmp" instructions.
 347
 348         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
 349         "di", and "ei" instructions correctly.
 350
 351         * interp.c (do_format_3): Get operands correctly and call
 352         the target function.
 353         * simops.c: Handle bCC instructions.
 354
 355         * simops.c: Add condition code handling to shift insns.
 356         Fix minor typos in condition code handling for other insns.
 357
 358         * Makefile.in: Fix typo.
 359         * simops.c: Add condition code handling to "sub" "subr" and
 360         "divh" instructions.
 361
 362         * interp.c (hash): Update to be more accurate.
 363         (lookup_hash): Call hash rather than computing the hash
 364         code here.
 365         (do_format_1_2): Handle format 1 and format 2 instructions.
 366         Get operands correctly and call the target function.
 367         (do_format_6): Get operands correctly and call the target
 368         function.
 369         (do_formats_9_10): Rough cut so shift ops will work.
 370         (sim_resume): Tweak to deal with format 1 and format 2
 371         handling in a single funtion.  Don't update the PC
 372         for format 3 insns.  Fix typos.
 373         * simops.c: Slightly reorganize.  Add condition code handling
 374         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
 375         and "not" instructions.
 376         * v850_sim.h (reg_t): Registers are 32bits.
 377         (_state): The V850 has 32 general registers.  Add a 32bit
 378         psw and pc register too.  Add accessor macros
 379
 380         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
 381         changes from the d10v simulator.
 382
 383         * simops.c: Add shift support.
 384
 385         * simops.c: Add multiply & divide support.  Abort for system
 386         instructions.
 387
 388         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
 389         and subr.  No condition codes yet.
