 347
 348         * simops.c: (all functions): Change all #ifdef DEBUG code so that
 349         the input and output values can be traced, along with the
 350         instruction type.  Make the -t option enable tracing.

 352         function in the callback table.
 353

 355         instructions are done left first or right first.
 356         (do_{long,2_short,parallel}): Indicate in the machine state which
 357         type of instruction this is.  Count each of the types of
 358         instructions executed.

 360         flag is set.

 365         sim_resume.
 366         (sim_info): Print out statistics on instructions.
 367         (sim_{trace,create_inferior}): Eliminate extraneous output unless
 368         debugging.

 370         Only initialize the hash table the first time sim_open is called.
 371
 372         * Makefile.in: Make objects depend on d10v_sim.h.
 373         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
 374         CFLAGS does not override host/target defines or SIM_CFLAGS.
 375         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
 376         (run): By default, the math library is not needed to be linked
 377         in.
 378         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
 379         overridden.
 380         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU

 384         (gencode{,.o},d10v-opc.o): Split compilation into creating object
 385         and linking.  Instead of linking in libopcodes.a, just compile
 386         d10v-opc.o directly to handle canadian cross.
 387         (CSEARCH): Add opcodes directory.
 388
 389         * configure.in (--enable-sim-cflags): New switch to allow user to
 390         set the defaults.
 391         (CC_FOR_BUILD): Deal with canadian crosses.
 392         * configure: Regenerate.
