1096
1097         * v850_sim.h: The V850 doesn't have split I&D spaces.  Change
1098         accordingly.  Remove many unused definitions.
1099         * interp.c: The V850 doesn't have split I&D spaces.  Change
1100         accordingly.

1104         (get_byte, get_half, get_word): New functions.
1105         (put_byte, put_half, put_word): New functions.
1106         * simops.c: Remove unused functions.  Rough cut at
1107         "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1108
1109         * v850_sim.h (struct _state): Remove "psw" field.  Add
1110         "sregs" field.
1111         (PSW): Remove bogus definition.
1112         * simops.c: Change condition code handling to use the psw
1113         register within the sregs array.  Handle "ldsr" and "stsr".
1114
1115         * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1116
1117         * interp.c (do_format_5): Get operands correctly and
1118         call the target function.
1119         (sim_resume): Don't do a PC update for format 5 instructions.
1120         * simops.c: Handle "jarl" and "jmp" instructions.
1121

1133         * simops.c: Add condition code handling to "sub" "subr" and
1134         "divh" instructions.
1135
1136         * interp.c (hash): Update to be more accurate.
1137         (lookup_hash): Call hash rather than computing the hash
1138         code here.
1139         (do_format_1_2): Handle format 1 and format 2 instructions.
1140         Get operands correctly and call the target function.
1141         (do_format_6): Get operands correctly and call the target
1142         function.

1146         for format 3 insns.  Fix typos.
1147         * simops.c: Slightly reorganize.  Add condition code handling
1148         to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"

1150         * v850_sim.h (reg_t): Registers are 32bits.
1151         (_state): The V850 has 32 general registers.  Add a 32bit
