1082         * v850_sim.h (struct _state): Remove "psw" field.  Add
1083         "sregs" field.
1084         (PSW): Remove bogus definition.
1085         * simops.c: Change condition code handling to use the psw
1086         register within the sregs array.  Handle "ldsr" and "stsr".
1087
1088         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1089
1090         * interp.c (do_format_5): Get operands correctly and
1091         call the target function.
1092         (sim_resume): Don't do a PC update for format 5 instructions.
1093         * simops.c: Handle "jarl" and "jmp" instructions.
1094
1095         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
1096         "di", and "ei" instructions correctly.
1097
1098         * interp.c (do_format_3): Get operands correctly and call
1099         the target function.
1100         * simops.c: Handle bCC instructions.
1101
1102         * simops.c: Add condition code handling to shift insns.
1103         Fix minor typos in condition code handling for other insns.
1104
1105         * Makefile.in: Fix typo.
1106         * simops.c: Add condition code handling to "sub" "subr" and
1107         "divh" instructions.
1108
1109         * interp.c (hash): Update to be more accurate.
1110         (lookup_hash): Call hash rather than computing the hash
1111         code here.
1112         (do_format_1_2): Handle format 1 and format 2 instructions.
1113         Get operands correctly and call the target function.
1114         (do_format_6): Get operands correctly and call the target
1115         function.
1116         (do_formats_9_10): Rough cut so shift ops will work.
1117         (sim_resume): Tweak to deal with format 1 and format 2
1118         handling in a single funtion.  Don't update the PC
1119         for format 3 insns.  Fix typos.
1120         * simops.c: Slightly reorganize.  Add condition code handling
1121         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1122         and "not" instructions.
1123         * v850_sim.h (reg_t): Registers are 32bits.
1124         (_state): The V850 has 32 general registers.  Add a 32bit
1125         psw and pc register too.  Add accessor macros
1126
1127         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1128         changes from the d10v simulator.
1129
1130         * simops.c: Add shift support.
1131
1132         * simops.c: Add multiply & divide support.  Abort for system
1133         instructions.
1134
1135         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1136         and subr.  No condition codes yet.
