1078         * simops.c: Handle "jarl" and "jmp" instructions.
1079
1080         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
1081         "di", and "ei" instructions correctly.
1082
1083         * interp.c (do_format_3): Get operands correctly and call
1084         the target function.
1085         * simops.c: Handle bCC instructions.
1086
1087         * simops.c: Add condition code handling to shift insns.
1088         Fix minor typos in condition code handling for other insns.
1089
1090         * Makefile.in: Fix typo.
1091         * simops.c: Add condition code handling to "sub" "subr" and
1092         "divh" instructions.
1093
1094         * interp.c (hash): Update to be more accurate.
1095         (lookup_hash): Call hash rather than computing the hash
1096         code here.
1097         (do_format_1_2): Handle format 1 and format 2 instructions.
1098         Get operands correctly and call the target function.
1099         (do_format_6): Get operands correctly and call the target
1100         function.
1101         (do_formats_9_10): Rough cut so shift ops will work.
1102         (sim_resume): Tweak to deal with format 1 and format 2
1103         handling in a single funtion.  Don't update the PC
1104         for format 3 insns.  Fix typos.
1105         * simops.c: Slightly reorganize.  Add condition code handling
1106         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1107         and "not" instructions.
1108         * v850_sim.h (reg_t): Registers are 32bits.
1109         (_state): The V850 has 32 general registers.  Add a 32bit
1110         psw and pc register too.  Add accessor macros
1111
1112         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1113         changes from the d10v simulator.
1114
1115         * simops.c: Add shift support.
1116
1117         * simops.c: Add multiply & divide support.  Abort for system
1118         instructions.
1119
1120         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1121         and subr.  No condition codes yet.
