1018 * simops.c (OP_2600, OP_2601): Changed min and max comparisons
1019 to use signed register values.
1021 Wed Sep 4 11:35:17 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1023 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1025 (_ins_type): New enumeration to specify which container an
1026 instruction is in, and whether it is part of a parallel operation.
1027 (_state): Add ins_type field.
1028 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.
1029 (ins_type_counters): Counters for the various instruction types.
1030 ({left,right}_nops): Counters for the number of nops in each
1032 (d10v_debug): New variable to indicate whether debugging is turned
1035 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1036 the input and output values can be traced, along with the
1037 instruction type. Make the -t option enable tracing.
1038 (all functions): Change printf calls to use the printf_filtered
1039 function in the callback table.
1041 * interp.c (_leftright): New enumeration to say whether 2 short
1042 instructions are done left first or right first.
1043 (do_{long,2_short,parallel}): Indicate in the machine state which
1044 type of instruction this is. Count each of the types of
1045 instructions executed.
1046 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1048 (sim_resume): Pass left/right indication to do_2_short.
1049 (all functions): Change printf calls to use the printf_filtered
1050 function in the callback table.
1051 (sim_trace): Turn on debug flag if DEBUG was defined, and call
1053 (sim_info): Print out statistics on instructions.
1054 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1056 (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
1057 Only initialize the hash table the first time sim_open is called.
1059 * Makefile.in: Make objects depend on d10v_sim.h.
1060 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1061 CFLAGS does not override host/target defines or SIM_CFLAGS.
1062 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1063 (run): By default, the math library is not needed to be linked
1065 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1067 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
1069 ({run,callback}.o): Provide explicit paths to their appropriate
1071 (gencode{,.o},d10v-opc.o): Split compilation into creating object
1072 and linking. Instead of linking in libopcodes.a, just compile
1073 d10v-opc.o directly to handle canadian cross.
1074 (CSEARCH): Add opcodes directory.
1076 * configure.in (--enable-sim-cflags): New switch to allow user to
1078 (CC_FOR_BUILD): Deal with canadian crosses.
1079 * configure: Regenerate.
1081 Wed Sep 04 04:45:34 1996 Mark Alexander <marka@cygnus.com>
1083 * simops.c: Include correct syscall.h for d10v, not host's.
1084 Fix #ifdef SYS_stat.
1086 Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com>
1088 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
1089 Add trap 2 to be printf and trap 3 to be putchar.
1091 Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com>
1093 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support
1094 for low-level system calls.
1096 Wed Aug 28 17:33:19 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1098 * Makefile.in, d10v_sim.h, interp.c: Fix byte-order problems.
1100 Mon Aug 26 18:30:28 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1102 * d10v_sim.h (SEXT32): Added.
1103 * interp.c: Commented out printfs.
1104 * simops.c: Fixed error in sb and st2w.
1106 Thu Aug 15 13:30:03 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
1108 * Makefile.in, d10v_sim.h, interp.c, simops.c: Added remaining
1109 DSP instructions. Added modulo addressing.

1122 gencode.c, interp.c, simops.c: Created.
