1091
1092         * v850_sim.h (struct _state): Remove "psw" field.  Add
1093         "sregs" field.
1094         (PSW): Remove bogus definition.
1095         * simops.c: Change condition code handling to use the psw

1097
1098         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1099
1100         * interp.c (do_format_5): Get operands correctly and
1101         call the target function.
1102         (sim_resume): Don't do a PC update for format 5 instructions.
1103         * simops.c: Handle "jarl" and "jmp" instructions.

1109         the target function.
1110         * simops.c: Handle bCC instructions.
1111
1112         * simops.c: Add condition code handling to shift insns.
1113         Fix minor typos in condition code handling for other insns.
1114
1115         * Makefile.in: Fix typo.
1116         * simops.c: Add condition code handling to "sub" "subr" and
1117         "divh" instructions.
1118
1119         * interp.c (hash): Update to be more accurate.
1120         (lookup_hash): Call hash rather than computing the hash
1121         code here.
1122         (do_format_1_2): Handle format 1 and format 2 instructions.
1123         Get operands correctly and call the target function.
1124         (do_format_6): Get operands correctly and call the target
1125         function.
1126         (do_formats_9_10): Rough cut so shift ops will work.
1127         (sim_resume): Tweak to deal with format 1 and format 2
1128         handling in a single funtion.  Don't update the PC
1129         for format 3 insns.  Fix typos.
1130         * simops.c: Slightly reorganize.  Add condition code handling
1131         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1132         and "not" instructions.
1133         * v850_sim.h (reg_t): Registers are 32bits.
1134         (_state): The V850 has 32 general registers.  Add a 32bit
1135         psw and pc register too.  Add accessor macros
1136
1137         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1138         changes from the d10v simulator.
1139
1140         * simops.c: Add shift support.
1141
1142         * simops.c: Add multiply & divide support.  Abort for system
1143         instructions.
1144
1145         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1146         and subr.  No condition codes yet.
