1086 * interp.c (do_format_8): Get operands correctly and
1087 call the target function.
1088 * simops.c: Rough cut at "clr1", "not1", "set1", and "tst1".

1092 * interp.c (do_format_4): Get operands correctly and
1093 call the target function.
1094 * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
1095 "sst.h", and "sst.w".
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
1101 (get_longlong, get_longword, get_word): Deleted.
1102 (write_longlong, write_longword, write_word): Deleted.
1103 (get_operands): Deleted.
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.
1109 * v850_sim.h (struct _state): Remove "psw" field. Add
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".
1115 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
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.
1122 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1123 "di", and "ei" instructions correctly.
1125 * interp.c (do_format_3): Get operands correctly and call
1126 the target function.
1127 * simops.c: Handle bCC instructions.
1129 * simops.c: Add condition code handling to shift insns.
1130 Fix minor typos in condition code handling for other insns.
1132 * Makefile.in: Fix typo.
1133 * simops.c: Add condition code handling to "sub" "subr" and
1134 "divh" instructions.
1136 * interp.c (hash): Update to be more accurate.
1137 (lookup_hash): Call hash rather than computing the hash
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
1143 (do_formats_9_10): Rough cut so shift ops will work.
1144 (sim_resume): Tweak to deal with format 1 and format 2
1145 handling in a single funtion. Don't update the PC
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"
1149 and "not" instructions.
1150 * v850_sim.h (reg_t): Registers are 32bits.
1151 (_state): The V850 has 32 general registers. Add a 32bit
1152 psw and pc register too. Add accessor macros
1154 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1155 changes from the d10v simulator.
1157 * simops.c: Add shift support.
1159 * simops.c: Add multiply & divide support. Abort for system
1162 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1163 and subr. No condition codes yet.

1167 * ChangeLog, Makefile.in, configure, configure.in, v850_sim.h,
1168 gencode.c, interp.c, simops.c: Created.
