 359         * interp.c (do_format_4): Get operands correctly and
 360         call the target function.
 361         * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
 362         "sst.h", and "sst.w".
 363
 364         * v850_sim.h: The V850 doesn't have split I&D spaces.  Change
 365         accordingly.  Remove many unused definitions.
 366         * interp.c: The V850 doesn't have split I&D spaces.  Change
 367         accordingly.
 368         (get_longlong, get_longword, get_word): Deleted.
 369         (write_longlong, write_longword, write_word): Deleted.
 370         (get_operands): Deleted.
 371         (get_byte, get_half, get_word): New functions.
 372         (put_byte, put_half, put_word): New functions.
 373         * simops.c: Remove unused functions.  Rough cut at
 374         "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
 375
 376         * v850_sim.h (struct _state): Remove "psw" field.  Add
 377         "sregs" field.
 378         (PSW): Remove bogus definition.
 379         * simops.c: Change condition code handling to use the psw
 380         register within the sregs array.  Handle "ldsr" and "stsr".
 381
 382         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
 383
 384         * interp.c (do_format_5): Get operands correctly and
 385         call the target function.
 386         (sim_resume): Don't do a PC update for format 5 instructions.
 387         * simops.c: Handle "jarl" and "jmp" instructions.
 388
 389         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
 390         "di", and "ei" instructions correctly.
 391
 392         * interp.c (do_format_3): Get operands correctly and call
 393         the target function.
 394         * simops.c: Handle bCC instructions.
 395
 396         * simops.c: Add condition code handling to shift insns.
 397         Fix minor typos in condition code handling for other insns.
 398
 399         * Makefile.in: Fix typo.
 400         * simops.c: Add condition code handling to "sub" "subr" and
 401         "divh" instructions.
 402
 403         * interp.c (hash): Update to be more accurate.
 404         (lookup_hash): Call hash rather than computing the hash
 405         code here.
 406         (do_format_1_2): Handle format 1 and format 2 instructions.
 407         Get operands correctly and call the target function.
 408         (do_format_6): Get operands correctly and call the target
 409         function.
 410         (do_formats_9_10): Rough cut so shift ops will work.
 411         (sim_resume): Tweak to deal with format 1 and format 2
 412         handling in a single funtion.  Don't update the PC
 413         for format 3 insns.  Fix typos.
 414         * simops.c: Slightly reorganize.  Add condition code handling
 415         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
 416         and "not" instructions.
 417         * v850_sim.h (reg_t): Registers are 32bits.
 418         (_state): The V850 has 32 general registers.  Add a 32bit
 419         psw and pc register too.  Add accessor macros
 420
 421         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
 422         changes from the d10v simulator.
 423
 424         * simops.c: Add shift support.
 425
 426         * simops.c: Add multiply & divide support.  Abort for system
 427         instructions.
 428
 429         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
 430         and subr.  No condition codes yet.
