1324 on.
1325
1326 * simops.c: (all functions): Change all #ifdef DEBUG code so that
1327 the input and output values can be traced, along with the
1328 instruction type. Make the -t option enable tracing.
1329 (all functions): Change printf calls to use the printf_filtered
1330 function in the callback table.

1332 * interp.c (_leftright): New enumeration to say whether 2 short
1333 instructions are done left first or right first.

1335 type of instruction this is. Count each of the types of
1336 instructions executed.
1337 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug
1338 flag is set.
1339 (sim_resume): Pass left/right indication to do_2_short.
1340 (all functions): Change printf calls to use the printf_filtered
1341 function in the callback table.

1343 sim_resume.
1344 (sim_info): Print out statistics on instructions.
1345 (sim_{trace,create_inferior}): Eliminate extraneous output unless
1346 debugging.

1349
1350 * Makefile.in: Make objects depend on d10v_sim.h.
1351 ({,SIM_}CFLAGS): Include configure dependent switches. Setting
1352 CFLAGS does not override host/target defines or SIM_CFLAGS.

1355 in.
