1085 * interp.c: Remove various debugging printfs.
1087 * simops.c: Fix satadd, satsub boundary case handling.
1089 * interp.c (hash): Fix.
1090 * interp.c (do_format_8): Get operands correctly and
1091 call the target function.
1092 * simops.c: Rough cut at "clr1", "not1", "set1", and "tst1".

1096 * interp.c (do_format_4): Get operands correctly and
1097 call the target function.
1098 * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
1099 "sst.h", and "sst.w".
1101 * v850_sim.h: The V850 doesn't have split I&D spaces. Change
1102 accordingly. Remove many unused definitions.
1103 * interp.c: The V850 doesn't have split I&D spaces. Change
1105 (get_longlong, get_longword, get_word): Deleted.
1106 (write_longlong, write_longword, write_word): Deleted.
1107 (get_operands): Deleted.
1108 (get_byte, get_half, get_word): New functions.
1109 (put_byte, put_half, put_word): New functions.
1110 * simops.c: Remove unused functions. Rough cut at
1111 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1113 * v850_sim.h (struct _state): Remove "psw" field. Add
1115 (PSW): Remove bogus definition.
1116 * simops.c: Change condition code handling to use the psw
1117 register within the sregs array. Handle "ldsr" and "stsr".
1119 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1121 * interp.c (do_format_5): Get operands correctly and
1122 call the target function.
1123 (sim_resume): Don't do a PC update for format 5 instructions.
1124 * simops.c: Handle "jarl" and "jmp" instructions.
1126 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1127 "di", and "ei" instructions correctly.
1129 * interp.c (do_format_3): Get operands correctly and call
1130 the target function.
1131 * simops.c: Handle bCC instructions.
1133 * simops.c: Add condition code handling to shift insns.
1134 Fix minor typos in condition code handling for other insns.
1136 * Makefile.in: Fix typo.
1137 * simops.c: Add condition code handling to "sub" "subr" and
1138 "divh" instructions.
1140 * interp.c (hash): Update to be more accurate.
1141 (lookup_hash): Call hash rather than computing the hash
1143 (do_format_1_2): Handle format 1 and format 2 instructions.
1144 Get operands correctly and call the target function.
1145 (do_format_6): Get operands correctly and call the target
1147 (do_formats_9_10): Rough cut so shift ops will work.
1148 (sim_resume): Tweak to deal with format 1 and format 2
1149 handling in a single funtion. Don't update the PC
1150 for format 3 insns. Fix typos.
1151 * simops.c: Slightly reorganize. Add condition code handling
1152 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1153 and "not" instructions.
1154 * v850_sim.h (reg_t): Registers are 32bits.
1155 (_state): The V850 has 32 general registers. Add a 32bit
1156 psw and pc register too. Add accessor macros
1158 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1159 changes from the d10v simulator.
1161 * simops.c: Add shift support.
1163 * simops.c: Add multiply & divide support. Abort for system
1166 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1167 and subr. No condition codes yet.
