1788
1789         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1790         the input and output values can be traced, along with the
1791         instruction type.  Make the -t option enable tracing.

1793         function in the callback table.
1794
1795         * interp.c (_leftright): New enumeration to say whether 2 short
1796         instructions are done left first or right first.
1797         (do_{long,2_short,parallel}): Indicate in the machine state which

1801         flag is set.
1802         (sim_resume): Pass left/right indication to do_2_short.

1806         sim_resume.
1807         (sim_info): Print out statistics on instructions.
1808         (sim_{trace,create_inferior}): Eliminate extraneous output unless

1813         * Makefile.in: Make objects depend on d10v_sim.h.
1814         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1815         CFLAGS does not override host/target defines or SIM_CFLAGS.
1816         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1817         (run): By default, the math library is not needed to be linked
1818         in.

1824         source directories.
1825         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1826         and linking.  Instead of linking in libopcodes.a, just compile
1827         d10v-opc.o directly to handle canadian cross.
1828         (CSEARCH): Add opcodes directory.
1829
1830         * configure.in (--enable-sim-cflags): New switch to allow user to
1831         set the defaults.
