1834         * v850_sim.h: The V850 doesn't have split I&D spaces.  Change
1835         accordingly.  Remove many unused definitions.

1848         (PSW): Remove bogus definition.
1849         * simops.c: Change condition code handling to use the psw
1850         register within the sregs array.  Handle "ldsr" and "stsr".
1851
1852         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1853
1854         * interp.c (do_format_5): Get operands correctly and
1855         call the target function.
1856         (sim_resume): Don't do a PC update for format 5 instructions.
1857         * simops.c: Handle "jarl" and "jmp" instructions.

1865
1866         * simops.c: Add condition code handling to shift insns.
1867         Fix minor typos in condition code handling for other insns.
1868
1869         * Makefile.in: Fix typo.
1870         * simops.c: Add condition code handling to "sub" "subr" and
1871         "divh" instructions.
1872
1873         * interp.c (hash): Update to be more accurate.
1874         (lookup_hash): Call hash rather than computing the hash
1875         code here.
1876         (do_format_1_2): Handle format 1 and format 2 instructions.
1877         Get operands correctly and call the target function.
1878         (do_format_6): Get operands correctly and call the target
1879         function.
1880         (do_formats_9_10): Rough cut so shift ops will work.
1881         (sim_resume): Tweak to deal with format 1 and format 2
1882         handling in a single funtion.  Don't update the PC
1883         for format 3 insns.  Fix typos.
1884         * simops.c: Slightly reorganize.  Add condition code handling
1885         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1886         and "not" instructions.
1887         * v850_sim.h (reg_t): Registers are 32bits.
1888         (_state): The V850 has 32 general registers.  Add a 32bit
1889         psw and pc register too.  Add accessor macros
1890
1891         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1892         changes from the d10v simulator.
1893
