1782         on.
1783
1784         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1785         the input and output values can be traced, along with the
1786         instruction type.  Make the -t option enable tracing.

1788         function in the callback table.
1789
1790         * interp.c (_leftright): New enumeration to say whether 2 short
1791         instructions are done left first or right first.
1792         (do_{long,2_short,parallel}): Indicate in the machine state which
1793         type of instruction this is.  Count each of the types of
1794         instructions executed.
1795         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1796         flag is set.

1801         sim_resume.
1802         (sim_info): Print out statistics on instructions.
1803         (sim_{trace,create_inferior}): Eliminate extraneous output unless
1804         debugging.

1808         * Makefile.in: Make objects depend on d10v_sim.h.
1809         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1810         CFLAGS does not override host/target defines or SIM_CFLAGS.
1811         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1812         (run): By default, the math library is not needed to be linked
1813         in.
1814         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1815         overridden.

1819         source directories.
1820         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1821         and linking.  Instead of linking in libopcodes.a, just compile
1822         d10v-opc.o directly to handle canadian cross.
1823         (CSEARCH): Add opcodes directory.
1824
1825         * configure.in (--enable-sim-cflags): New switch to allow user to
1826         set the defaults.
