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