 724         call the target function.
 725         (sim_resume): Don't do a PC update for format 5 instructions.
 726         * simops.c: Handle "jarl" and "jmp" instructions.
 727
 728         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
 729         "di", and "ei" instructions correctly.
 730
 731         * interp.c (do_format_3): Get operands correctly and call
 732         the target function.
 733         * simops.c: Handle bCC instructions.
 734
 735         * simops.c: Add condition code handling to shift insns.
 736         Fix minor typos in condition code handling for other insns.
 737
 738         * Makefile.in: Fix typo.
 739         * simops.c: Add condition code handling to "sub" "subr" and
 740         "divh" instructions.
 741
 742         * interp.c (hash): Update to be more accurate.
 743         (lookup_hash): Call hash rather than computing the hash
 744         code here.
 745         (do_format_1_2): Handle format 1 and format 2 instructions.
 746         Get operands correctly and call the target function.
 747         (do_format_6): Get operands correctly and call the target
 748         function.
 749         (do_formats_9_10): Rough cut so shift ops will work.
 750         (sim_resume): Tweak to deal with format 1 and format 2
 751         handling in a single funtion.  Don't update the PC
 752         for format 3 insns.  Fix typos.
 753         * simops.c: Slightly reorganize.  Add condition code handling
 754         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
 755         and "not" instructions.
 756         * v850_sim.h (reg_t): Registers are 32bits.
 757         (_state): The V850 has 32 general registers.  Add a 32bit
 758         psw and pc register too.  Add accessor macros
 759
 760         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
 761         changes from the d10v simulator.
 762
 763         * simops.c: Add shift support.
 764
 765         * simops.c: Add multiply & divide support.  Abort for system
 766         instructions.
 767
 768         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
 769         and subr.  No condition codes yet.
