1033 Fri Dec 6 14:13:34 1996 Jeffrey A Law (law@cygnus.com)
1035 * simops.c: Call abort for any instruction that's not currently
1038 * simops.c: Define accessor macros to extract register
1039 values from instructions. Use them consistently.
1041 * interp.c: Delete unused global variable "OP".
1042 (sim_resume): Remove unused variable "opcode".
1043 * simops.c: Fix some uninitialized variable problems, add
1044 parens to fix various -Wall warnings.
1046 * gencode.c (write_header): Add "insn" and "extension" arguments
1047 to the OP_* declarations.
1048 (write_template): Similarly for function templates.
1049 * interp.c (insn, extension): Remove global variables. Instead
1050 pass them as arguments to the OP_* functions.
1051 * mn10300_sim.h: Remove decls for "insn" and "extension".
1052 * simops.c (OP_*): Accept "insn" and "extension" as arguments
1053 instead of using globals.

1057 * simops.c: Fix typos in "mov am,(d16,an)" and "mov am,(d32,an)"
1059 * simops.c: Fix thinkos in last change to "inc dn".
1061 Wed Dec 4 10:57:53 1996 Jeffrey A Law (law@cygnus.com)
1063 * simops.c: "add imm,sp" does not effect the condition codes.
1064 "inc dn" does effect the condition codes.

1071 * simops.c: Fix simulation of division instructions.

1076 * simops.c: Fix carry bit handling in "sub" and "cmp"
1079 * simops.c: Fix "mov imm8,an" and "mov imm16,dn".
1081 Sun Dec 1 16:05:42 1996 Jeffrey A Law (law@cygnus.com)
1083 * simops.c: Fix overflow computation for many instructions.
1085 * simops.c: Fix "mov dm, an", "movbu dm, (an)", and "movhu dm, (an)".
1087 * simops.c: Fix "mov am, dn".
1089 * simops.c: Fix more bugs in "add imm,an" and
1092 Wed Nov 27 09:20:42 1996 Jeffrey A Law (law@cygnus.com)
1094 * simops.c: Fix bugs in "movm" and "add imm,an".
1096 * simops.c: Don't lose the upper 24 bits of the return
1097 pointer in "call" and "calls" instructions. Rough cut
1098 at emulated system calls.
1100 * simops.c: Implement the remaining 5, 6 and 7 byte instructions.
1102 * simops.c: Implement remaining 4 byte instructions.
1104 * simops.c: Implement remaining 3 byte instructions.
1106 * simops.c: Implement remaining 2 byte instructions. Call
1107 abort for instructions we're not implementing now.

1111 * simops.c: Implement lots of random instructions.
1113 * simops.c: Implement "movm" and "bCC" insns.
1115 * mn10300_sim.h (_state): Add another register (MDR).
1117 * simops.c: Implement "cmp", "calls", "rets", "jmp" and
1118 a few additional random insns.
