1079 (PSW): Remove bogus definition.
1080 * simops.c: Change condition code handling to use the psw
1081 register within the sregs array. Handle "ldsr" and "stsr".
1083 * simops.c: Handle "satadd", "satsub", "satsubi", "satsubr".
1085 * interp.c (do_format_5): Get operands correctly and
1086 call the target function.
1087 (sim_resume): Don't do a PC update for format 5 instructions.
1088 * simops.c: Handle "jarl" and "jmp" instructions.
1090 * simops.c: Fix minor typos. Handle "cmp", "setf", "tst"
1091 "di", and "ei" instructions correctly.
1093 * interp.c (do_format_3): Get operands correctly and call
1094 the target function.
1095 * simops.c: Handle bCC instructions.
1097 * simops.c: Add condition code handling to shift insns.
1098 Fix minor typos in condition code handling for other insns.
1100 * Makefile.in: Fix typo.
1101 * simops.c: Add condition code handling to "sub" "subr" and
1102 "divh" instructions.
1104 * interp.c (hash): Update to be more accurate.
1105 (lookup_hash): Call hash rather than computing the hash
1107 (do_format_1_2): Handle format 1 and format 2 instructions.
1108 Get operands correctly and call the target function.
1109 (do_format_6): Get operands correctly and call the target
1111 (do_formats_9_10): Rough cut so shift ops will work.
1112 (sim_resume): Tweak to deal with format 1 and format 2
1113 handling in a single funtion. Don't update the PC
1114 for format 3 insns. Fix typos.
1115 * simops.c: Slightly reorganize. Add condition code handling
1116 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
1117 and "not" instructions.
1118 * v850_sim.h (reg_t): Registers are 32bits.
1119 (_state): The V850 has 32 general registers. Add a 32bit
1120 psw and pc register too. Add accessor macros
1122 * Makefile.in, interp.c, v850_sim.h: Bring over endianness
1123 changes from the d10v simulator.
1125 * simops.c: Add shift support.
1127 * simops.c: Add multiply & divide support. Abort for system
1130 * simops.c: Add logicals, mov, movhi, movea, add, addi, sub
1131 and subr. No condition codes yet.

1135 * ChangeLog, Makefile.in, configure, configure.in, v850_sim.h,
1136 gencode.c, interp.c, simops.c: Created.
