1423         call the target function.
1424         * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
1425         "sst.h", and "sst.w".
1426
1427         * v850_sim.h: The V850 doesn't have split I&D spaces.  Change
1428         accordingly.  Remove many unused definitions.
1429         * interp.c: The V850 doesn't have split I&D spaces.  Change
1430         accordingly.
1431         (get_longlong, get_longword, get_word): Deleted.
1432         (write_longlong, write_longword, write_word): Deleted.
1433         (get_operands): Deleted.
1434         (get_byte, get_half, get_word): New functions.
1435         (put_byte, put_half, put_word): New functions.
1436         * simops.c: Remove unused functions.  Rough cut at
1437         "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1438
1439         * v850_sim.h (struct _state): Remove "psw" field.  Add
1440         "sregs" field.
1441         (PSW): Remove bogus definition.
1442         * simops.c: Change condition code handling to use the psw
1443         register within the sregs array.  Handle "ldsr" and "stsr".
1444
1445         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1446
1447         * interp.c (do_format_5): Get operands correctly and
1448         call the target function.
1449         (sim_resume): Don't do a PC update for format 5 instructions.
1450         * simops.c: Handle "jarl" and "jmp" instructions.
1451
1452         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
1453         "di", and "ei" instructions correctly.
1454
1455         * interp.c (do_format_3): Get operands correctly and call
1456         the target function.
1457         * simops.c: Handle bCC instructions.
1458
1459         * simops.c: Add condition code handling to shift insns.
1460         Fix minor typos in condition code handling for other insns.
1461
1462         * Makefile.in: Fix typo.
1463         * simops.c: Add condition code handling to "sub" "subr" and
1464         "divh" instructions.
1465
1466         * interp.c (hash): Update to be more accurate.
1467         (lookup_hash): Call hash rather than computing the hash
1468         code here.
1469         (do_format_1_2): Handle format 1 and format 2 instructions.
1470         Get operands correctly and call the target function.
1471         (do_format_6): Get operands correctly and call the target
1472         function.
1473         (do_formats_9_10): Rough cut so shift ops will work.
1474         (sim_resume): Tweak to deal with format 1 and format 2
1475         handling in a single funtion.  Don't update the PC
1476         for format 3 insns.  Fix typos.
1477         * simops.c: Slightly reorganize.  Add condition code handling
1478         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1479         and "not" instructions.
1480         * v850_sim.h (reg_t): Registers are 32bits.
1481         (_state): The V850 has 32 general registers.  Add a 32bit
1482         psw and pc register too.  Add accessor macros
1483
1484         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1485         changes from the d10v simulator.
1486
1487         * simops.c: Add shift support.
