1407
1408         * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug
1409         output.
1410         (_ins_type): New enumeration to specify which container an
1411         instruction is in, and whether it is part of a parallel operation.
1412         (_state): Add ins_type field.
1413         ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types.

1418         on.
1419
1420         * simops.c: (all functions): Change all #ifdef DEBUG code so that
1421         the input and output values can be traced, along with the
1422         instruction type.  Make the -t option enable tracing.
1423         (all functions): Change printf calls to use the printf_filtered
1424         function in the callback table.
1425
1426         * interp.c (_leftright): New enumeration to say whether 2 short
1427         instructions are done left first or right first.
1428         (do_{long,2_short,parallel}): Indicate in the machine state which
1429         type of instruction this is.  Count each of the types of
1430         instructions executed.
1431         (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1432         flag is set.
1433         (sim_resume): Pass left/right indication to do_2_short.
1434         (all functions): Change printf calls to use the printf_filtered
1435         function in the callback table.
1436         (sim_trace): Turn on debug flag if DEBUG was defined, and call
1437         sim_resume.
1438         (sim_info): Print out statistics on instructions.
1439         (sim_{trace,create_inferior}): Eliminate extraneous output unless

1443
1444         * Makefile.in: Make objects depend on d10v_sim.h.
1445         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting
1446         CFLAGS does not override host/target defines or SIM_CFLAGS.
1447         (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode.
1448         (run): By default, the math library is not needed to be linked
1449         in.
1450         ({BFD,LIBIBERTY}_LIB): Define as variables so they can be
1451         overridden.

1455         source directories.
1456         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1457         and linking.  Instead of linking in libopcodes.a, just compile
1458         d10v-opc.o directly to handle canadian cross.
1459         (CSEARCH): Add opcodes directory.
1460
1461         * configure.in (--enable-sim-cflags): New switch to allow user to
1462         set the defaults.
