1779
1780         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1781         the input and output values can be traced, along with the
1782         instruction type.  Make the -t option enable tracing.

1792         flag is set.

1797         sim_resume.
1798         (sim_info): Print out statistics on instructions.
1799         (sim_{trace,create_inferior}): Eliminate extraneous output unless

1803
1804         * Makefile.in: Make objects depend on d10v_sim.h.
1805         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1806         CFLAGS does not override host/target defines or SIM_CFLAGS.
1807         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1808         (run): By default, the math library is not needed to be linked
1809         in.
1810         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1811         overridden.

1815         source directories.
1816         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1817         and linking.  Instead of linking in libopcodes.a, just compile
1818         d10v-opc.o directly to handle canadian cross.
1819         (CSEARCH): Add opcodes directory.
1820
1821         * configure.in (--enable-sim-cflags): New switch to allow user to
1822         set the defaults.
