Hunt <hunt@pizza.cygnus.com> 1288 1289 * simops.c (OP_2600, OP_2601): Changed min and max comparisons 1290 to use signed register values. 1291 1292Wed Sep 4 11:35:17 1996 Michael Meissner <meissner@tiktok.cygnus.com> 1293 1294 * d10v_sim.h (DEBUG_*): Add bit flags for controlling debug 1295 output. 1296 (_ins_type): New enumeration to specify which container an 1297 instruction is in, and whether it is part of a parallel operation. 1298 (_state): Add ins_type field. 1299 ({,u}int{8,16,32,64}): Use limits.h to size the appropriate types. 1300 (ins_type_counters): Counters for the various instruction types. 1301 ({left,right}_nops): Counters for the number of nops in each 1302 container. 1303 (d10v_debug): New variable to indicate whether debugging is turned 1304 on. 1305 1306 * simops.c: (all functions): Change all #ifdef DEBUG code so that 1307 the input and output values can be traced, along with the 1308 instruction type. Make the -t option enable tracing. 1309 (all functions): Change printf calls to use the printf_filtered 1310 function in the callback table. 1311 1312 * interp.c (_leftright): New enumeration to say whether 2 short 1313 instructions are done left first or right first. 1314 (do_{long,2_short,parallel}): Indicate in the machine state which 1315 type of instruction this is. Count each of the types of 1316 instructions executed. 1317 (sim_size): Only print the memory sizes if DEBUG_MEMSIZE debug 1318 flag is set. 1319 (sim_resume): Pass left/right indication to do_2_short. 1320 (all functions): Change printf calls to use the printf_filtered 1321 function in the callback table. 1322 (sim_trace): Turn on debug flag if DEBUG was defined, and call 1323 sim_resume. 1324 (sim_info): Print out statistics on instructions. 1325 (sim_{trace,create_inferior}): Eliminate extraneous output unless 1326 debugging. 1327 (sim_open): If args == -t and DEBUG was defined, set d10v_debug. 1328 Only initialize the hash table the first time sim_open is called. 1329 1330 * Makefile.in: Make objects depend on d10v_sim.h. 1331 ({,SIM_}CFLAGS): Include configure dependent switches. Setting 1332 CFLAGS does not override host/target defines or SIM_CFLAGS. 1333 (CC_FOR_BUILD,gencode): Use CC_FOR_BUILD to compile gencode. 1334 (run): By default, the math library is not needed to be linked 1335 in. 1336 ({BFD,LIBIBERTY}_LIB): Define as variables so they can be 1337 overridden. 1338 (VPATH): Don't set to anything but @srcdir@ to work with non-GNU 1339 makes. 1340 ({run,callback}.o): Provide explicit paths to their appropriate 1341 source directories. 1342 (gencode{,.o},d10v-opc.o): Split compilation into creating object 1343 and linking. Instead of linking in libopcodes.a, just compile 1344 d10v-opc.o directly to handle canadian cross. 1345 (CSEARCH): Add opcodes directory. 1346 1347 * configure.in (--enable-sim-cflags): New switch to allow user to 1348 set the defaults. 1349 (CC_FOR_BUILD): Deal with canadian crosses. 1350 * configure: Regenerate. 1351 1352Wed Sep 04 04:45:34 1996 Mark Alexander <marka@cygnus.com> 1353 1354 * simops.c: Include correct syscall.h for d10v, not host's. 1355 Fix #ifdef SYS_stat. 1356 1357Tue Sep 3 14:00:04 1996 Michael Meissner <meissner@tiktok.cygnus.com> 1358 1359 * simops.c (OP_5F00): Wrap all SYS_xxx traps with #ifdef. 1360 Add trap 2 to be printf and trap 3 to be putchar. 1361 1362Wed Aug 28 21:42:34 1996 Mark Alexander <marka@cygnus.com> 1363 1364 * Makefile.in, d10v_sim.h, interp.c, simops.c: Add support 1365 for low-level system calls. 1366 1367Wed Aug 28 17:33:19 1996 Martin M.
