1082 * interp.c (sim_resume): Fix code to check for a format 3
1084 * simops.c: bCC insns only argument is a constant, not a
1085 register value (duh...)
1087 Fri Aug 30 10:33:49 1996 Jeffrey A Law (law@cygnus.com)
1089 * simops.c: Fix "not1" and "set1".
1091 * simops.c: Don't forget to initialize temp for
1094 * interp.c: Remove various debugging printfs.
1096 * simops.c: Fix satadd, satsub boundary case handling.
1098 * interp.c (hash): Fix.
1099 * interp.c (do_format_8): Get operands correctly and
1100 call the target function.
1101 * simops.c: Rough cut at "clr1", "not1", "set1", and "tst1".

1105 * interp.c (do_format_4): Get operands correctly and
1106 call the target function.
1107 * simops.c: Rough cut at "sld.b", "sld.h", "sld.w", "sst.b",
1108 "sst.h", and "sst.w".
1110 * v850_sim.h: The V850 doesn't have split I&D spaces. Change
1111 accordingly. Remove many unused definitions.
1112 * interp.c: The V850 doesn't have split I&D spaces. Change
1114 (get_longlong, get_longword, get_word): Deleted.
1115 (write_longlong, write_longword, write_word): Deleted.
1116 (get_operands): Deleted.
1117 (get_byte, get_half, get_word): New functions.
1118 (put_byte, put_half, put_word): New functions.
1119 * simops.c: Remove unused functions. Rough cut at
1120 "ld.b", "ld.h", "ld.w", "st.b", "st.h", "st.w" insns.
1122 * v850_sim.h (struct _state): Remove "psw" field. Add
1124 (PSW): Remove bogus definition.
1125 * simops.c: Change condition code handling to use the psw
1126 register within the sregs array. Handle "ldsr" and "stsr".
1128 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1130 * interp.c (do_format_5): Get operands correctly and
1131 call the target function.
1132 (sim_resume): Don't do a PC update for format 5 instructions.
1133 * simops.c: Handle "jarl" and "jmp" instructions.
1135 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1136 "di", and "ei" instructions correctly.
1138 * interp.c (do_format_3): Get operands correctly and call
1139 the target function.
1140 * simops.c: Handle bCC instructions.
1142 * simops.c: Add condition code handling to shift insns.
1143 Fix minor typos in condition code handling for other insns.
1145 * Makefile.in: Fix typo.
1146 * simops.c: Add condition code handling to "sub" "subr" and
1147 "divh" instructions.
1149 * interp.c (hash): Update to be more accurate.
1150 (lookup_hash): Call hash rather than computing the hash
1152 (do_format_1_2): Handle format 1 and format 2 instructions.
1153 Get operands correctly and call the target function.
1154 (do_format_6): Get operands correctly and call the target
1156 (do_formats_9_10): Rough cut so shift ops will work.
1157 (sim_resume): Tweak to deal with format 1 and format 2
1158 handling in a single funtion. Don't update the PC
1159 for format 3 insns. Fix typos.
1160 * simops.c: Slightly reorganize. Add condition code handling
1161 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1162 and "not" instructions.
1163 * v850_sim.h (reg_t): Registers are 32bits.
1164 (_state): The V850 has 32 general registers. Add a 32bit
1165 psw and pc register too. Add accessor macros
1167 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1168 changes from the d10v simulator.
1170 * simops.c: Add shift support.
1172 * simops.c: Add multiply & divide support. Abort for system
1175 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1176 and subr. No condition codes yet.
