1079 * interp.c (do_format_5): Get operands correctly and
1080 call the target function.
1081 (sim_resume): Don't do a PC update for format 5 instructions.
1082 * simops.c: Handle "jarl" and "jmp" instructions.
1084 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1085 "di", and "ei" instructions correctly.
1087 * interp.c (do_format_3): Get operands correctly and call
1088 the target function.
1089 * simops.c: Handle bCC instructions.
1091 * simops.c: Add condition code handling to shift insns.
1092 Fix minor typos in condition code handling for other insns.
1094 * Makefile.in: Fix typo.
1095 * simops.c: Add condition code handling to "sub" "subr" and
1096 "divh" instructions.
1098 * interp.c (hash): Update to be more accurate.
1099 (lookup_hash): Call hash rather than computing the hash
1101 (do_format_1_2): Handle format 1 and format 2 instructions.
1102 Get operands correctly and call the target function.
1103 (do_format_6): Get operands correctly and call the target
1105 (do_formats_9_10): Rough cut so shift ops will work.
1106 (sim_resume): Tweak to deal with format 1 and format 2
1107 handling in a single funtion. Don't update the PC
1108 for format 3 insns. Fix typos.
1109 * simops.c: Slightly reorganize. Add condition code handling
1110 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1111 and "not" instructions.
1112 * v850_sim.h (reg_t): Registers are 32bits.
1113 (_state): The V850 has 32 general registers. Add a 32bit
1114 psw and pc register too. Add accessor macros
1116 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1117 changes from the d10v simulator.
1119 * simops.c: Add shift support.
1121 * simops.c: Add multiply & divide support. Abort for system
1124 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1125 and subr. No condition codes yet.
