1792
1793         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1794         the input and output values can be traced, along with the
1795         instruction type.  Make the -t option enable tracing.

1797         function in the callback table.
1798
1799         * interp.c (_leftright): New enumeration to say whether 2 short

1805         flag is set.
1806         (sim_resume): Pass left/right indication to do_2_short.

1810         sim_resume.
1811         (sim_info): Print out statistics on instructions.
1812         (sim_{trace,create_inferior}): Eliminate extraneous output unless

1817         * Makefile.in: Make objects depend on d10v_sim.h.
1818         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1819         CFLAGS does not override host/target defines or SIM_CFLAGS.
1820         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1821         (run): By default, the math library is not needed to be linked
1822         in.

1828         source directories.
1829         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1830         and linking.  Instead of linking in libopcodes.a, just compile
1831         d10v-opc.o directly to handle canadian cross.
1832         (CSEARCH): Add opcodes directory.
1833
1834         * configure.in (--enable-sim-cflags): New switch to allow user to
1835         set the defaults.
