 393         (PSW): Remove bogus definition.
 394         * simops.c: Change condition code handling to use the psw

 401         (sim_resume): Don't do a PC update for format 5 instructions.
 402         * simops.c: Handle "jarl" and "jmp" instructions.
 403

 418         * interp.c (hash): Update to be more accurate.
 419         (lookup_hash): Call hash rather than computing the hash
 420         code here.
 421         (do_format_1_2): Handle format 1 and format 2 instructions.
 422         Get operands correctly and call the target function.

 428         for format 3 insns.  Fix typos.
 429         * simops.c: Slightly reorganize.  Add condition code handling
 430         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"

 432         * v850_sim.h (reg_t): Registers are 32bits.
 433         (_state): The V850 has 32 general registers.  Add a 32bit
 434         psw and pc register too.  Add accessor macros
 435

 437         changes from the d10v simulator.
 438
 439         * simops.c: Add shift support.
