1081 accordingly. Remove many unused definitions.
1082 * interp.c: The V850 doesn't have split I&D spaces. Change
1084 (get_longlong, get_longword, get_word): Deleted.
1085 (write_longlong, write_longword, write_word): Deleted.
1086 (get_operands): Deleted.
1087 (get_byte, get_half, get_word): New functions.
1088 (put_byte, put_half, put_word): New functions.
1089 * simops.c: Remove unused functions. Rough cut at
1090 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1092 * v850_sim.h (struct _state): Remove "psw" field. Add
1094 (PSW): Remove bogus definition.
1095 * simops.c: Change condition code handling to use the psw
1096 register within the sregs array. Handle "ldsr" and "stsr".
1098 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1100 * interp.c (do_format_5): Get operands correctly and
1101 call the target function.
1102 (sim_resume): Don't do a PC update for format 5 instructions.
1103 * simops.c: Handle "jarl" and "jmp" instructions.
1105 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1106 "di", and "ei" instructions correctly.
1108 * interp.c (do_format_3): Get operands correctly and call
1109 the target function.
1110 * simops.c: Handle bCC instructions.
1112 * simops.c: Add condition code handling to shift insns.
1113 Fix minor typos in condition code handling for other insns.
1115 * Makefile.in: Fix typo.
1116 * simops.c: Add condition code handling to "sub" "subr" and
1117 "divh" instructions.
1119 * interp.c (hash): Update to be more accurate.
1120 (lookup_hash): Call hash rather than computing the hash
1122 (do_format_1_2): Handle format 1 and format 2 instructions.
1123 Get operands correctly and call the target function.
1124 (do_format_6): Get operands correctly and call the target
1126 (do_formats_9_10): Rough cut so shift ops will work.
1127 (sim_resume): Tweak to deal with format 1 and format 2
1128 handling in a single funtion. Don't update the PC
1129 for format 3 insns. Fix typos.
1130 * simops.c: Slightly reorganize. Add condition code handling
1131 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1132 and "not" instructions.
1133 * v850_sim.h (reg_t): Registers are 32bits.
1134 (_state): The V850 has 32 general registers. Add a 32bit
1135 psw and pc register too. Add accessor macros
1137 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1138 changes from the d10v simulator.
1140 * simops.c: Add shift support.
1142 * simops.c: Add multiply & divide support. Abort for system
1145 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1146 and subr. No condition codes yet.

1150 * ChangeLog, Makefile.in, configure, configure.in, v850_sim.h,
1151 gencode.c, interp.c, simops.c: Created.
