 339         (sim_resume): Pass left/right indication to do_2_short.
 340         (all functions): Change printf calls to use the printf_filtered
 341         function in the callback table.
 342         (sim_trace): Turn on debug flag if DEBUG was defined, and call
 343         sim_resume.
 344         (sim_info): Print out statistics on instructions.
 345         (sim_{trace,create_inferior}): Eliminate extraneous output unless
 346         debugging.
 347         (sim_open): If args == -t and DEBUG was defined, set d10v_debug.
 348         Only initialize the hash table the first time sim_open is called.
 349
 350         * Makefile.in: Make objects depend on d10v_sim.h.
 351         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
 352         CFLAGS does not override host/target defines or SIM_CFLAGS.
 353         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
 354         (run): By default, the math library is not needed to be linked
 355         in.
 356         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
 357         overridden.
 358         (VPATH): Don't set to anything but @srcdir@ to work with non-GNU
 359         makes.

 361         source directories.
 362         (gencode{,.o},d10v-opc.o): Split compilation into creating object
 363         and linking.  Instead of linking in libopcodes.a, just compile
 364         d10v-opc.o directly to handle canadian cross.
 365         (CSEARCH): Add opcodes directory.
 366
 367         * configure.in (--enable-sim-cflags): New switch to allow user to
 368         set the defaults.
 369         (CC_FOR_BUILD): Deal with canadian crosses.
 370         * configure: Regenerate.
