 339         on.
 340
 341         * simops.c: (all functions): Change all #ifdef DEBUG code so that
 342         the input and output values can be traced, along with the
 343         instruction type.  Make the -t option enable tracing.
 344         (all functions): Change printf calls to use the printf_filtered
 345         function in the callback table.
 346
 347         * interp.c (_leftright): New enumeration to say whether 2 short
 348         instructions are done left first or right first.
 349         (do_{long,2_short,parallel}): Indicate in the machine state which
 350         type of instruction this is.  Count each of the types of
 351         instructions executed.
 352         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
 353         flag is set.
 354         (sim_resume): Pass left/right indication to do_2_short.
 355         (all functions): Change printf calls to use the printf_filtered
 356         function in the callback table.
 357         (sim_trace): Turn on debug flag if DEBUG was defined, and call
 358         sim_resume.
 359         (sim_info): Print out statistics on instructions.
 360         (sim_{trace,create_inferior}): Eliminate extraneous output unless
 361         debugging.
 362         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
 363         Only initialize the hash table the first time sim_open is called.
 364
 365         * Makefile.in: Make objects depend on d10v_sim.h.
 366         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
 367         CFLAGS does not override host/target defines or SIM_CFLAGS.
 368         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
 369         (run): By default, the math library is not needed to be linked
 370         in.
 371         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
 372         overridden.
 373         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
 374         makes.
 375         ({run,callback}.o): Provide explicit paths to their appropriate
 376         source directories.
 377         (gencode{,.o},d10v-opc.o): Split compilation into creating object
 378         and linking.  Instead of linking in libopcodes.a, just compile
 379         d10v-opc.o directly to handle canadian cross.
 380         (CSEARCH): Add opcodes directory.
 381
 382         * configure.in (--enable-sim-cflags): New switch to allow user to
 383         set the defaults.
 384         (CC_FOR_BUILD): Deal with canadian crosses.
 385         * configure: Regenerate.

 388
 389         * simops.c: Include correct syscall.h for d10v, not host's.
 390         Fix #ifdef SYS_stat.

 392 Tue Sep  3 14:00:04 1996  Michael Meissner  <meissner@tiktok.cygnus.com>
 393
 394         * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef.
 395         Add trap 2 to be printf and trap 3 to be putchar.
