1084         "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1085
1086         * v850_sim.h (struct _state): Remove "psw" field.  Add
1087         "sregs" field.
1088         (PSW): Remove bogus definition.
1089         * simops.c: Change condition code handling to use the psw
1090         register within the sregs array.  Handle "ldsr" and "stsr".
1091
1092         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1093
1094         * interp.c (do_format_5): Get operands correctly and
1095         call the target function.
1096         (sim_resume): Don't do a PC update for format 5 instructions.
1097         * simops.c: Handle "jarl" and "jmp" instructions.
1098
1099         * simops.c: Fix minor typos.  Handle "cmp", "setf", "tst"
1100         "di", and "ei" instructions correctly.
1101
1102         * interp.c (do_format_3): Get operands correctly and call
1103         the target function.
1104         * simops.c: Handle bCC instructions.
1105
1106         * simops.c: Add condition code handling to shift insns.
1107         Fix minor typos in condition code handling for other insns.
1108
1109         * Makefile.in: Fix typo.
1110         * simops.c: Add condition code handling to "sub" "subr" and
1111         "divh" instructions.
1112
1113         * interp.c (hash): Update to be more accurate.
1114         (lookup_hash): Call hash rather than computing the hash
1115         code here.
1116         (do_format_1_2): Handle format 1 and format 2 instructions.
1117         Get operands correctly and call the target function.
1118         (do_format_6): Get operands correctly and call the target
1119         function.
1120         (do_formats_9_10): Rough cut so shift ops will work.
1121         (sim_resume): Tweak to deal with format 1 and format 2
1122         handling in a single funtion.  Don't update the PC
1123         for format 3 insns.  Fix typos.
1124         * simops.c: Slightly reorganize.  Add condition code handling
1125         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1126         and "not" instructions.
1127         * v850_sim.h (reg_t): Registers are 32bits.
1128         (_state): The V850 has 32 general registers.  Add a 32bit
1129         psw and pc register too.  Add accessor macros
1130
1131         * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1132         changes from the d10v simulator.
1133
1134         * simops.c: Add shift support.
1135
1136         * simops.c: Add multiply & divide support.  Abort for system
1137         instructions.
1138
1139         * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1140         and subr.  No condition codes yet.
