1862         * simops.c: Change condition code handling to use the psw
1863         register within the sregs array.  Handle "ldsr" and "stsr".
1864
1865         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1866

1868         call the target function.
1869         (sim_resume): Don't do a PC update for format 5 instructions.
1870         * simops.c: Handle "jarl" and "jmp" instructions.

1884         "divh" instructions.
1885
1886         * interp.c (hash): Update to be more accurate.
1887         (lookup_hash): Call hash rather than computing the hash
1888         code here.
