7 Thu Dec 14 18:49:34 1995 Andrew Cagney <cagney@highland.com.au>
9 * lf.c (lf_print_function_type): New function. Munges a function
10 type so that the prefix (eg INLINE...) is inserted after the type
13 * igen.c: Change to output functions using this.
15 Wed Dec 13 23:47:00 1995 Andrew Cagney <cagney@highland.com.au>
17 FIXME: Emul CHIRP does not correctly implement the find device
20 FIXME: Emul CHIRP and device do not implement device instance

25 * options.c (options_inline): Function to output meaningful
26 description of the INLINE options.

52 pure and simple static (instead of STATIC_MODEL).
54 Tue Dec 5 00:45:34 1995 Andrew Cagney <cagney@highland.com.au>
56 * sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass
57 an options device into psim_create() so that options can be merged
60 * device.c (*add*): Change semantics so the add functions only add
61 when the new device (or property) doesn't already exist. This

80 suport for inlineing of modules for all callers. Adjust relevant
81 macro's so that DEFAULT_INLINE will enable this.

87 * basics.h (__attribute__), sim_callbacks.h: Move attribute macro
88 to basics.h and add hack (include <stdio.h>) to try and bring that
89 and other possible conflicting macros into scope much earler.

132 For convenience, change the printd functions into device_tree_add
135 * psim.c (create_*_tree): Use new device_tree create functions.
137 * corefile.h, corefile.c corefile-n.h (core_n.h): Update to use
138 the new device.h / device_table.h interface. Rename core_n.h to
139 corefile-n.h to be consistent with other n files.
141 * Makefile.in (run): add corefile-n.h to dependencies for
144 * basics.h (device_instance), device.h, device.c, device_table.h,
145 device_table.c: Add the concept of a device instance and operators
146 on these instances - corresponds to ihandle in OpenBoot speak.
147 Don't yet implement it.

190 and code for spa, no longer to be used.
192 * psim.c (create_chirp_device_tree): Fill out what was previously
193 the openboot create function so that it starts to create a full
194 OpenBoot device tree.
196 Tue Nov 28 21:48:06 1995 Andrew Cagney <cagney@highland.com.au>

216 host is little endian, not big endian and if WITH_NTOH is defined.
218 * configure{,.in} (--enable-sim-model-issue): Instead of defining
219 0/1, define it to be MODEL_ISSUE_{PROCESS,IGNORE}. Add

263 * std-config.h (MODEL_INLINE): If not defined, define as 1 if
264 DEFAULT_INLINE is non-zero, 0 otherwise, rather than just the

279 semantics is to use the cache structure directly rather than
280 putting the values into local variables.
281 (first_undef, last_undef): New structures to remember names to
283 (lf_print_c_extraction): If -R and this is semantics, emit names
284 as #defines pointing to the cache structure, rather than loading
285 the values into local variables.
286 (lf_print_c_semantic_function): If -R, #undef all of the names
287 defined in lf_print_c_extraction.
288 (main): Recognize -R.
290 * idecode_fields.h (SPR_*): Redefine spr_* macros as SPR_* to
291 avoid a name confict if -R passed to igen.

345 Sun Nov 19 23:00:52 1995 Michael Meissner <meissner@tiktok.cygnus.com>
347 * ppc-instructions (model data, model_busy): Rather than using a
348 bit mask for the busy units, just use a char array. Also, only
349 support 2 function units an insn can use, rather than a loop.
351 Fri Nov 17 14:08:08 1995 Michael Meissner <meissner@tiktok.cygnus.com>
353 * table.c (table_entry_read): Move setting entry->line_nr to after
354 the model specific fields so the line numbers for the annex are
357 * cpu.c (cpu_{create,init,halt}): Check for WITH_MODEL_ISSUE
358 before calling the model functions.
360 * debug.c (trace_descriptor): Add trace_model support.
361 * debug.h (trace_options): Ditto.
363 * igen.c (gen_icache_h): Create type idecode_cache as void if not

374 * mon.c: Use count_type instead of unsigned.
376 * ppc-instructions: Redo scheduling code once again. Make it all
377 inline friendly. Instead of having general code emitted by igen,
378 go the route of having each semantic routine call the appropriate

383 * table.c (table_entry_read): Allow the annex to have blank lines.
385 * ppc-instructions: Change lines in model stuff that just have a
386 tab to just newline. Add 601 support. Document most instructions
387 in terms of model specific timing information. Drop 'FUNCTION'
388 from PPC_FUNCTION_UNIT_xxx enums. Change PPC_UNIT_UNKNOWN ->
389 PPC_UNIT_BAD. Add TRACE(trace_tbd) for all data cache
390 instruction.s. Signal illegal instruciton if data cache block
391 invalidate is issued from problem state.
393 * igen.c (max_model_fields_len): New static to keep track of the
394 max size for the model specific fields.
395 (model_c_insn): Use max_model_fields_len to size fields.
396 (insn_table_insert_insn): Set max_model_fields_len.

401 * debug.c (trace_description): Add support for trace_tbd.
403 * mon.c (mon_issue): Pass processor argument to model_issue.

413 * Makefile.in: Ditto.
415 * function_unit.{c,h}: Delete these now usused files.

421 * Makefile.in: Add --enable-sim-model-issue flags.
422 * igen.c (lf_print_c_semantic): Add call to mon_issue here. Check
423 for WITH_MODEL_ISSUE.
424 * mon.c (mon_issue): Remove call to mon_issue_here.
426 * ppc-instructions: Move branch tracing to the actual branch
427 instructions, rather than testing it in model_issue. Add code to
428 code successful/unsuccessful branch predictions, and the number of
429 conditional branches that fell through.
431 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
433 * cpu.h (cpu_model): Add declaration.

492 * cpu.c (cpu_get_time_base): Fix calculation of current value of
495 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
496 m[tf]tb with m[tf]spr.
498 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
501 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
503 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
504 inline.. Only problem being that with ppc-opcode-simple this gave
505 it the chance to inline all the idecode functions with potentially
506 disasterous results on a 16mb PC. For moment hobble INLINE.
508 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
511 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
512 Firstly make them errors and secondly remove the options gcc-245
515 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
517 * misc.c (zalloc), cpu.c (cpu_init), devices
518 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
519 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
520 sim_calls.c (zalloc) : replace bzero() with memset().
522 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
523 psim_write_register): replace bcopy() with memcpy().
525 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
527 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
528 force DEFAULT_INLINE to 0 rather then trusting the std
531 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
533 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
534 generation of switch entries in tables - treat the same as
535 cracking/semantic functions.
537 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
538 of a boolean switch statement (field zero or non-zero).
540 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
541 switch/table generation ability of igen.
543 * igen.c (idecode_switch_leaf): Fix code output when a switch
544 statement needs to look up a table.
546 * igen.c (idecode_declare_if_switch): New function called from
547 gen_idecode_c - need to declare any idecode switch functions
548 before they are used in idecode tables.
550 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
551 idecode_crack_insn): Add is_inline_function argument to code
552 printing cracker functions which indicates if STATIC_IDECODE or
553 STATIC_INLINE_IDECODE should be used for definition. For
554 idecode_crack_insn (which implies not duplicating/expanding) don't
555 declare function as inline - we assume that the only time this is
556 code is generated is when things are being tested. For
557 idecode_crack_leaf, make static (instead of INLINE) if the
558 instructions parent is a table as function will always be called
561 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
562 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
563 called directly, all others are called via a table.
565 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
566 semantics_h_insn, semantics_h_function,
567 lf_print_c_semantic_function, semantics_c_function): Add
568 is_inline_function argument to lf_print_semantic_function_header
569 to indicate if an inline or static function declaration/definition
570 should be output. Depending on situtation call accordingly:
571 functions (not instruction semantic routines) are always inline;
572 Semantic routines are made inline when there is no icache (cache
573 will contain the function address) and are duplicating (see above)
574 and the parent of the instruction is a switch statement.

1130 give about a 10% gain in performance if everything enabled. Also
1131 takes about 150mb of swap to build.
1133 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1135 * emul_netbsd.c (do_exit): Print arguments and close parenthesis
1136 if tracing, since exit doesn't go through emul_exit_call.

1166 * Makefile.in: Add filter_filename support.
1168 * ppc-instructions (dcbi, icbi): Make these NOPs rather than
1169 invalid instructions.
1171 * configure.in: Add support for more --enable-sim-* switches.
1172 Use config.make and config.hdr to write to Makefile and config.h
1173 respectively. Don't rewrite Makefile, just append to it.
1174 * configure: Regenerate.
1175 * config.{make,hdr}: New shell scripts.
1177 * Makefile.in: Remove all variables set by configure.in.
1178 (psim.o): Depend on $(BUILT_SRC) also.
1180 * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an
1181 integer, use 0, not NULL.
1183 Tue Oct 31 15:20:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1185 * configure.in: Add support for --enable-sim-inline,
1186 --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex,

1188 and --enable-sim-endian switch to control various Makefile
1190 * configure: Regenerate from configure.in.
1191 * Makefile.in: Add various Make variables that the various
1194 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
1195 and optimizing by default.
1197 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
1199 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1200 make them functions again. Appears 2.6.3 is confused by just a
1203 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1205 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
1207 * psim.c (psim_create): Not correctly checking that runtime
1208 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1209 matched the compiled in ones.
1211 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1212 trace_semantics is now different to trace_idecode, the former
1215 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
1217 * ppc-instructions (mtsrin): Missing instruction
1218 * ppc-instructions (mfsrin): Missing instruction
1219 * ppc-instructions (eieio): Missing instruction
1221 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
1223 * build-psim: New shell script - see internals for usage,
1224 simplifies the process of building custom simulators.
1226 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
1228 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1229 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1230 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1231 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1232 the instruction or data critical paths.
1234 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1235 the inclusion of device_tree.c/emul_generic.c.
1237 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1239 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

1246 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
1248 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1249 the processor is started. Fixes problem of registers being
1250 undefined when restarting from within gdb.
1252 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1253 instruction cache (if present). Fixes problem of cpu caching gdb
1254 breakpoint instructions.
1256 FIXME: PSIM sometimes aborts calling error(), it should instead
1257 call sim_error() say which takes care of housekeeping such as
1258 saving the CIA before calling error.
1260 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1261 used when restarting a simulation because the latter has the
1262 unwanted side effect (well I as a kernel hacker think it is) of
1263 performing an isync when the instruction stream doesn't contain
1266 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1268 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1269 monitoring module. Counts both instructions issued and
1272 * NOTE: mon does not contain to count instruction loads as this
1273 information is already available from the mon_issue() hook.
1275 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1277 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1278 a common monitor to each of the cpus. Delete
1279 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1280 replaced by copied code in mon.[hc].
1282 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1284 * sim_calls.c, main.c, psim.c (psim_create): always create
1285 `WITH_SMP' cpus. The actual number of CPU's active in a
1286 simulation run is taken from the device node: /init/smp (an
1287 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1289 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1291 * system.c: More system call emulation. If code appears NetBSD
1292 specific, make conditional to being compiled on a NetBSD system
1295 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
1297 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1298 lf.[ch](new), table.[ch](new): Split into two generators - igen
1299 that outputs the instruction tables and dgen that outputs the spr
1300 tables. Add -f (filter out) flag to igen to filter out certain
1301 instructions (ex 64 bit ones) from the created tables. Include
1302 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1305 * NOTE: igen, since it was originally written for the
1306 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1308 * Makefile.in, std-config.h, ppc-cache-rules(new),
1309 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1310 cache-rule and opcode-rule tables from macros found std-config.h.
1311 Delete corresponding macro's from std-config.h.
1313 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1314 an table of all the instructions. Code to output a type
1315 enumerating all the instructin names.
1317 * igen.c(lf_print_c_semantic): Move call to increment instruction
1318 counter so that it occures _after_ the instruction has been fully
1319 validated, was double counting illegal/invalid instructions. Add
1320 conditional so only compiled in when WITH_PROFILE enabled (enabled
1323 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1324 itable.h, count individual instruction types not just total,
1325 adjust reporting functions to output this.
1327 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
1328 Had 32./ instead of 31./
1330 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1331 bitrot - updated to use newer CR register operators.
1333 * ppc-instructions (64bit Floating Convert from Integer
1334 Doubleword): Correct call to Round_Float().
1336 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1338 * basics.h: #include "sim_callbacks.h" earlier so that its
1339 prototypes are declared in all other header files.
1341 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1342 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1345 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1346 Add size of buffer argument to functions writing a string into a
1347 buffer. Check for buffer overflow.
1349 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1351 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1352 of each device. Make parameter names consistent so macros work.
1353 Use macro's in device functions.
1355 * device_tree.c, devices.h, devices.c: include path to device in a
1356 devices node when creating it.
1358 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
1360 * core.c: add tracing of core-device, adjust parameter names in
1361 core functions to be consistent with those in devices*.
1363 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
1365 * debug.h, debug.c (trace_option): New function. Parses the trace
1366 option, updating the trace array.
1368 * debug.h, debug.c (trace_usage): New function. Outputs the list
1369 of all possible trace options.
1371 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1372 parse trace options specified with the simpler -t flag. Adjust
1375 * FIXME: basic parsing of command line options is still duplicated
1376 by main.c and sim_calls.c
1378 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1380 * Makefile.in (clean): Delete *.i and *.out files.
1382 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1383 macros for either assignment or return. Fix SWAP_8 to use a
1384 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1385 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1386 that hardwired swapping on/off, let optimizer delete dead code.
1388 * main.c (main): Add printf that we caught a signal and print out
1389 the failing address.
1391 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1393 * Makefile.in: Remove tabs from otherwise empty line.
1394 Confuses many non-GNU versions of "make".

1403 instructions here so it works with caching.
1404 (gen_idecode_c): Move from here.
1406 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1408 * gen.c, ppc-instructions, psim.c: Fix code for generating
1409 cracking instruction cache. Delete the code that cached just the
1410 result from doing an instruction lookup - this ran slower than no
1413 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1415 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1417 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1418 TCL when gdb is linked with the simulator.
1419 * debug.c (ppc_trace): Ditto.
1420 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1421 * main.c (main): Ditto.

1428 psim.o depend on all sources.
1430 * cpu.c (cpu_add_commas): New function to format a long with
1432 (cpu_print_info): Use it to print number_of_insns.
1434 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1436 (ENDIAN_N): If both target and host byte orders are known, don't
1437 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1439 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1440 to allow target specific H2T_n/T2H_n macros to be used.
1441 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1442 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1443 of the 3 instruction sequence that runs on 386s.
1445 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1446 specified on the compile line.
1447 (WITH_BSWAP): If not defined, define as 0.
1449 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1450 default inline support. Pass INLINE_CFLAGS when compiling.
1452 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1453 INLINE_DEVICES since GCC doesn't like inline functions that
1454 accept variable arguments.
1455 (stack_ioctl_callback): Make function just static because GCC
1456 doesn't like inline functions that accept variable arguments.
1458 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1460 * inline.c: Correct pathnames of included C files to match current
1463 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1464 non-zero, define STATIC_DEVICES to be static.
1466 * std-config.h (INLINE): If GNU C and optimizing, define this as
1468 (DEFAULT_INLINE): If not defined, define as 0.
1469 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1470 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1471 ({SPREG,IDECODE}_INLINE): Ditto.
1473 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1475 * ppc-instructions: Initial cut of floating point suport added.
1476 Of note include - use of host IEEE floating point instructions,
1477 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1478 currently a pretty sight.
1480 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1481 merge into core.h, core.c, core_n.h. The type memory_map replaced
1482 with core_map. This removes a level of pointer indirection when
1483 translating an address.
1485 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1487 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1501 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1503 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1504 callback interface so that there is a read/write buffer but no
1505 read/write_word. VEA default memory read/write handler sometimes
1506 couldn't resolve an access and of those some were for a memory
1507 fault and some were because gdb was making a bogus request.
1509 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1510 eliminate transfer_mode (raw or cooked) parameter from read/write
1513 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1515 * ppc-instructions (fmul, fmuls): correct instruction format - had

1520 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1521 scand_*): new functions to parse/print fields in device names
1522 while hiding any machine dependency.
1524 * devices.c, psim.c: Change the stack init code so that it is
1525 handled by a device. Arguments passed across using a device ioctl
1528 * devices.h, devices.c: device ioctl callback changed to allow a
1529 variable number of arguments. This gives greater flexability and
1530 greater chance of bugs.
1532 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1534 * main.c (printf_filtered, error): Missing va_end() to close off
1535 variable argument use.
1537 * Makefile.in (tmp-gencode): comment out hack to get around some
1538 versions of make not handling files being created as side-effects.
1540 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1541 alternative file name to use in output files for things like #line
1544 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1547 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1567 At present, print the number of instructions executed.
1569 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1572 * psim.c (psim_print_info): New function to iterate over each of
1573 the CPU's calling cpu_print_info.
1575 * psim.h,cpu.h: Add new declarations.
1577 * sim_calls.c (sim_open): Add argument processing to add the same
1578 switches main.c accepts for the standalone processor.
1579 (sim_close): Call psim_print_info if -I.
1581 * main.c (main): Add comment saying to update sim_calls.c when
1582 adding switches. Add -I to call psim_print_info when done.

1604 * main.c (main): Switch to using getopt. Make -p also set
1605 trace_semantics. Make -a turn on all trace flags. Make -C turn
1608 * device_tree.c (create_option_device_node): Assume a program is
1609 OEA if the start address is < 4096, not just == 0.
1611 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>
1613 * Makefile.in (maintainer-clean): New synonym for realclean.

1657 * core.c (core_add_data): First growth of bss was being put at
1658 wrong address (0) instead of &end.
1660 * core.c (core_add_stack, core_add_data): Was not handling case
1661 where bss/stack is grown across the current end-of-{bss,stack}.
1663 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1665 * system.c (system_call): Fix SYS_break - was aligning bss to a
1666 page boundary instead of just an 8 byte one; On first call sbrk(0)
1669 Thu Aug 24 14:48:54 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1671 * Makefile.in (install): Fix install rule.
1673 Tue Aug 22 09:31:18 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1675 * system.c (system_call): Add read support.
1677 * main.c (main): -t sets trace_device_tree. Correct usage message
1680 * device_tree.c (update_memory_node_for_section): Make tracing
1681 output line up. If not code or readonly, assume that the section
1682 is a data section and has read/write permissions. Add readonly
1685 * core.c (create_core_from_addresses): Print end address in traces
1686 and make tracing output line up.
1688 * Makefile.in: Rewrite from Makefile to work with the Cygnus
1689 environment, and support compiling in a different directory than
1690 the sources reside in.
1692 * ppc-endian.h: Rename from endian.h so that it doesn't get
1693 confused with /usr/include/sys/endian.h on Linux. Add Linux
1696 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
1697 Include ppc-endian.h, not endian.h.
1699 * basics.h (sysdep.h): Include sysdep.h that configure makes.
1700 Include ppc-endian.h, not endian.h.
1702 * std-config.h: Rename from ppc-config. Put #ifndefs around most
1703 configuration macros, so they can be overridden via CFLAGS. By
1704 default, turn off tracing.
1706 * configure.in: Clone from other simulator targets.
1707 * configure: Generate via autoconf from configure.in.
1709 Sat Aug 19 09:05:32 1995 Andrew Cagney <cagney@highland.com.au>
1711 * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
1713 * interrupts.c (data_storage_interrupt): allow stack to grow by
1714 upto one MB per increment.
1716 * ppc-instructions: divw was computing rA / rA not rA / rB
1718 * main.c (main): really stupid. Wasn't exiting with correct status
1720 Fri Aug 18 00:38:01 1995 Andrew Cagney <cagney@highland.com.au>
1722 * system.c (system_call): add system calls kill(2) and getpid(2).
1724 * main.c (main): Check/return exit status when simulation
1727 Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney@highland.com.au>
1729 * device_tree.c (create_option_device_node): Alignment rules (at
1730 least for the moment) now are for strict alignment only for LE OEA
1731 mode. (Because of compiler problems).
1733 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
1735 Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
1737 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
1740 * system.c (system_call): didn't page align break argument before
1741 determining increment break increment.
1743 * psim/ppc: Re-arange entire directory structure so that
1744 everything lives in the one directory. While a pain for cleaning,
1745 makes building across multiple architectures much simpler.
1747 * devices.c, device_tree.c: Added code that provides a simple
1748 illustration of how an interrupt control device could be
1751 * devices.c: Added code so that the dumb console device can read
1752 (from stdin) as well as write to stdout.
