1085         * v850_sim.h: The V850 doesn't have split I&D spaces.  Change
1086         accordingly.  Remove many unused definitions.
1087         * interp.c: The V850 doesn't have split I&D spaces.  Change
1088         accordingly.

1098         "sregs" field.
1099         (PSW): Remove bogus definition.
1100         * simops.c: Change condition code handling to use the psw
1101         register within the sregs array.  Handle "ldsr" and "stsr".
1102
1103         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1104
1105         * interp.c (do_format_5): Get operands correctly and
1106         call the target function.
1107         (sim_resume): Don't do a PC update for format 5 instructions.
1108         * simops.c: Handle "jarl" and "jmp" instructions.

1116
1117         * simops.c: Add condition code handling to shift insns.
1118         Fix minor typos in condition code handling for other insns.
1119
1120         * Makefile.in: Fix typo.
1121         * simops.c: Add condition code handling to "sub" "subr" and
1122         "divh" instructions.
1123
1124         * interp.c (hash): Update to be more accurate.
1125         (lookup_hash): Call hash rather than computing the hash
1126         code here.
1127         (do_format_1_2): Handle format 1 and format 2 instructions.
1128         Get operands correctly and call the target function.
1129         (do_format_6): Get operands correctly and call the target
1130         function.
1131         (do_formats_9_10): Rough cut so shift ops will work.
1132         (sim_resume): Tweak to deal with format 1 and format 2
1133         handling in a single funtion.  Don't update the PC
1134         for format 3 insns.  Fix typos.
1135         * simops.c: Slightly reorganize.  Add condition code handling
1136         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1137         and "not" instructions.
1138         * v850_sim.h (reg_t): Registers are 32bits.
1139         (_state): The V850 has 32 general registers.  Add a 32bit
1140         psw and pc register too.  Add accessor macros
1141
1142         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1143         changes from the d10v simulator.
1144
1145         * simops.c: Add shift support.
1146
1147         * simops.c: Add multiply & divide support.  Abort for system
1148         instructions.
1149
1150         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1151         and subr.  No condition codes yet.
