1847
1848         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1849
1850         * interp.c (do_format_5): Get operands correctly and
1851         call the target function.
1852         (sim_resume): Don't do a PC update for format 5 instructions.

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