1023 * simops.c (OP_2600, OP_2601): Changed min and max comparisons
1024 to use signed register values.
1026 Wed Sep 4 11:35:17 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1028 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1030 (_ins_type): New enumeration to specify which container an
1031 instruction is in, and whether it is part of a parallel operation.
1032 (_state): Add ins_type field.
1033 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1034 (ins_type_counters): Counters for the various instruction types.
1035 ({left,right}_nops): Counters for the number of nops in each
1037 (d10v_debug): New variable to indicate whether debugging is turned
1040 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1041 the input and output values can be traced, along with the
1042 instruction type. Make the -t option enable tracing.
1043 (all functions): Change printf calls to use the printf_filtered
1044 function in the callback table.
1046 * interp.c (_leftright): New enumeration to say whether 2 short
1047 instructions are done left first or right first.
1048 (do_{long,2_short,parallel}): Indicate in the machine state which
1049 type of instruction this is. Count each of the types of
1050 instructions executed.
1051 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1053 (sim_resume): Pass left/right indication to do_2_short.
1054 (all functions): Change printf calls to use the printf_filtered
1055 function in the callback table.
1056 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1058 (sim_info): Print out statistics on instructions.
1059 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1061 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1062 Only initialize the hash table the first time sim_open is called.
1064 * Makefile.in: Make objects depend on d10v_sim.h.
1065 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1066 CFLAGS does not override host/target defines or SIM_CFLAGS.
1067 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1068 (run): By default, the math library is not needed to be linked
1070 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1072 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1074 ({run,callback}.o): Provide explicit paths to their appropriate
1076 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1077 and linking. Instead of linking in libopcodes.a, just compile
1078 d10v-opc.o directly to handle canadian cross.
1079 (CSEARCH): Add opcodes directory.
1081 * configure.in (--enable-sim-cflags): New switch to allow user to
1083 (CC_FOR_BUILD): Deal with canadian crosses.
1084 * configure: Regenerate.
1086 Wed Sep 04 04:45:34 1996 Mark Alexander <marka@cygnus.com>
1088 * simops.c: Include correct syscall.h for d10v, not host's.
1089 Fix #ifdef SYS_stat.
1091 Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1093 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1094 Add trap 2 to be printf and trap 3 to be putchar.
1096 Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com>
1098 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1099 for low-level system calls.
1101 Wed Aug 28 17:33:19 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1103 * Makefile.in, d10v_sim.h, interp.c: Fix byte-order problems.
1105 Mon Aug 26 18:30:28 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1107 * d10v_sim.h (SEXT32): Added.
1108 * interp.c: Commented out printfs.
1109 * simops.c: Fixed error in sb and st2w.
1111 Thu Aug 15 13:30:03 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1113 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1114 DSP instructions. Added modulo addressing.

1127 gencode.c, interp.c, simops.c: Created.
