3 * lf.c (lf_print_function_type): New function. Munges a function
4 type so that the prefix (eg INLINE...) is inserted after the type
7 * igen.c: Change to output functions using this.
9 Wed Dec 13 23:47:00 1995 Andrew Cagney <cagney@highland.com.au>
11 FIXME: Emul CHIRP does not correctly implement the find device

50 * sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass
51 an options device into psim_create() so that options can be merged
54 * device.c (*add*): Change semantics so the add functions only add
55 when the new device (or property) doesn't already exist. This

126 For convenience, change the printd functions into device_tree_add
129 * psim.c (create_*_tree): Use new device_tree create functions.
131 * corefile.h, corefile.c corefile-n.h (core_n.h): Update to use
132 the new device.h / device_table.h interface. Rename core_n.h to
133 corefile-n.h to be consistent with other n files.

138 * basics.h (device_instance), device.h, device.c, device_table.h,
139 device_table.c: Add the concept of a device instance and operators
140 on these instances - corresponds to ihandle in OpenBoot speak.
141 Don't yet implement it.

184 and code for spa, no longer to be used.
186 * psim.c (create_chirp_device_tree): Fill out what was previously

210 host is little endian, not big endian and if WITH_NTOH is defined.
212 * configure{,.in} (--enable-sim-model-issue): Instead of defining
213 0/1, define it to be MODEL_ISSUE_{PROCESS,IGNORE}. Add

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

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

339 Sun Nov 19 23:00:52 1995 Michael Meissner <meissner@tiktok.cygnus.com>
341 * ppc-instructions (model data, model_busy): Rather than using a
342 bit mask for the busy units, just use a char array. Also, only
343 support 2 function units an insn can use, rather than a loop.
345 Fri Nov 17 14:08:08 1995 Michael Meissner <meissner@tiktok.cygnus.com>
347 * table.c (table_entry_read): Move setting entry->line_nr to after
348 the model specific fields so the line numbers for the annex are
351 * cpu.c (cpu_{create,init,halt}): Check for WITH_MODEL_ISSUE
352 before calling the model functions.
354 * debug.c (trace_descriptor): Add trace_model support.

368 * mon.c: Use count_type instead of unsigned.
370 * ppc-instructions: Redo scheduling code once again. Make it all

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

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

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

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

1184 * configure: Regenerate from configure.in.
1185 * Makefile.in: Add various Make variables that the various
1188 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC

1191 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
1193 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1194 make them functions again. Appears 2.6.3 is confused by just a
1197 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1199 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
1201 * psim.c (psim_create): Not correctly checking that runtime
1202 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1203 matched the compiled in ones.
1205 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1206 trace_semantics is now different to trace_idecode, the former
1209 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
1211 * ppc-instructions (mtsrin): Missing instruction
1212 * ppc-instructions (mfsrin): Missing instruction
1213 * ppc-instructions (eieio): Missing instruction
1215 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
1217 * build-psim: New shell script - see internals for usage,
1218 simplifies the process of building custom simulators.
1220 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
1222 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1223 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1224 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1225 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1226 the instruction or data critical paths.
1228 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1229 the inclusion of device_tree.c/emul_generic.c.
1231 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1233 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

1242 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1243 the processor is started. Fixes problem of registers being
1244 undefined when restarting from within gdb.
1246 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1247 instruction cache (if present). Fixes problem of cpu caching gdb
1248 breakpoint instructions.
1250 FIXME: PSIM sometimes aborts calling error(), it should instead
1251 call sim_error() say which takes care of housekeeping such as
1252 saving the CIA before calling error.
1254 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1255 used when restarting a simulation because the latter has the
1256 unwanted side effect (well I as a kernel hacker think it is) of
1257 performing an isync when the instruction stream doesn't contain
1260 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1262 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1263 monitoring module. Counts both instructions issued and

1273 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1274 replaced by copied code in mon.[hc].
1276 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1278 * sim_calls.c, main.c, psim.c (psim_create): always create
1279 `WITH_SMP' cpus. The actual number of CPU's active in a
1280 simulation run is taken from the device node: /init/smp (an
1281 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1283 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1285 * system.c: More system call emulation. If code appears NetBSD
1286 specific, make conditional to being compiled on a NetBSD system
1289 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
1291 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1292 lf.[ch](new), table.[ch](new): Split into two generators - igen
1293 that outputs the instruction tables and dgen that outputs the spr
1294 tables. Add -f (filter out) flag to igen to filter out certain
1295 instructions (ex 64 bit ones) from the created tables. Include
1296 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1299 * NOTE: igen, since it was originally written for the
1300 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1302 * Makefile.in, std-config.h, ppc-cache-rules(new),
1303 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1304 cache-rule and opcode-rule tables from macros found std-config.h.
1305 Delete corresponding macro's from std-config.h.
1307 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1308 an table of all the instructions. Code to output a type
1309 enumerating all the instructin names.
1311 * igen.c(lf_print_c_semantic): Move call to increment instruction
1312 counter so that it occures _after_ the instruction has been fully
1313 validated, was double counting illegal/invalid instructions. Add
1314 conditional so only compiled in when WITH_PROFILE enabled (enabled
1317 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1318 itable.h, count individual instruction types not just total,
1319 adjust reporting functions to output this.

1322 Had 32./ instead of 31./
1324 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1325 bitrot - updated to use newer CR register operators.
1327 * ppc-instructions (64bit Floating Convert from Integer
1328 Doubleword): Correct call to Round_Float().
1330 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1332 * basics.h: #include "sim_callbacks.h" earlier so that its
1333 prototypes are declared in all other header files.
1335 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1336 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1339 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1340 Add size of buffer argument to functions writing a string into a
1341 buffer. Check for buffer overflow.
1343 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1345 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1346 of each device. Make parameter names consistent so macros work.
1347 Use macro's in device functions.
1349 * device_tree.c, devices.h, devices.c: include path to device in a
1350 devices node when creating it.
1352 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.

1355 core functions to be consistent with those in devices*.
1357 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
1359 * debug.h, debug.c (trace_option): New function. Parses the trace
1360 option, updating the trace array.
1362 * debug.h, debug.c (trace_usage): New function. Outputs the list
1363 of all possible trace options.
1365 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1366 parse trace options specified with the simpler -t flag. Adjust
1369 * FIXME: basic parsing of command line options is still duplicated
1370 by main.c and sim_calls.c
1372 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1374 * Makefile.in (clean): Delete *.i and *.out files.
1376 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1377 macros for either assignment or return. Fix SWAP_8 to use a
1378 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1379 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1380 that hardwired swapping on/off, let optimizer delete dead code.
1382 * main.c (main): Add printf that we caught a signal and print out
1383 the failing address.
1385 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1387 * Makefile.in: Remove tabs from otherwise empty line.

1397 instructions here so it works with caching.
1398 (gen_idecode_c): Move from here.
1400 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1402 * gen.c, ppc-instructions, psim.c: Fix code for generating
1403 cracking instruction cache. Delete the code that cached just the
1404 result from doing an instruction lookup - this ran slower than no
1407 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1409 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1411 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1412 TCL when gdb is linked with the simulator.
1413 * debug.c (ppc_trace): Ditto.

1422 psim.o depend on all sources.
1424 * cpu.c (cpu_add_commas): New function to format a long with
1426 (cpu_print_info): Use it to print number_of_insns.
1428 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1430 (ENDIAN_N): If both target and host byte orders are known, don't
1431 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1433 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1434 to allow target specific H2T_n/T2H_n macros to be used.
1435 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1436 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1437 of the 3 instruction sequence that runs on 386s.
1439 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1440 specified on the compile line.
1441 (WITH_BSWAP): If not defined, define as 0.
1443 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1444 default inline support. Pass INLINE_CFLAGS when compiling.
1446 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1447 INLINE_DEVICES since GCC doesn't like inline functions that
1448 accept variable arguments.
1449 (stack_ioctl_callback): Make function just static because GCC
1450 doesn't like inline functions that accept variable arguments.
1452 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1454 * inline.c: Correct pathnames of included C files to match current
1457 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1458 non-zero, define STATIC_DEVICES to be static.
1460 * std-config.h (INLINE): If GNU C and optimizing, define this as
1462 (DEFAULT_INLINE): If not defined, define as 0.
1463 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1464 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1465 ({SPREG,IDECODE}_INLINE): Ditto.
1467 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1469 * ppc-instructions: Initial cut of floating point suport added.
1470 Of note include - use of host IEEE floating point instructions,
1471 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1472 currently a pretty sight.
1474 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1475 merge into core.h, core.c, core_n.h. The type memory_map replaced
1476 with core_map. This removes a level of pointer indirection when
1477 translating an address.
1479 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1481 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1495 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1497 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1498 callback interface so that there is a read/write buffer but no
1499 read/write_word. VEA default memory read/write handler sometimes
1500 couldn't resolve an access and of those some were for a memory
1501 fault and some were because gdb was making a bogus request.
1503 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1504 eliminate transfer_mode (raw or cooked) parameter from read/write
1507 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1509 * ppc-instructions (fmul, fmuls): correct instruction format - had

1514 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1515 scand_*): new functions to parse/print fields in device names
1516 while hiding any machine dependency.
1518 * devices.c, psim.c: Change the stack init code so that it is
1519 handled by a device. Arguments passed across using a device ioctl
1522 * devices.h, devices.c: device ioctl callback changed to allow a
1523 variable number of arguments. This gives greater flexability and
1524 greater chance of bugs.
1526 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1528 * main.c (printf_filtered, error): Missing va_end() to close off
1529 variable argument use.
1531 * Makefile.in (tmp-gencode): comment out hack to get around some
1532 versions of make not handling files being created as side-effects.
1534 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1535 alternative file name to use in output files for things like #line
1538 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1541 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

1561 At present, print the number of instructions executed.
1563 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1566 * psim.c (psim_print_info): New function to iterate over each of
1567 the CPU's calling cpu_print_info.
1569 * psim.h,cpu.h: Add new declarations.
1571 * sim_calls.c (sim_open): Add argument processing to add the same
1572 switches main.c accepts for the standalone processor.
1573 (sim_close): Call psim_print_info if -I.
1575 * main.c (main): Add comment saying to update sim_calls.c when
1576 adding switches. Add -I to call psim_print_info when done.

1602 * device_tree.c (create_option_device_node): Assume a program is
1603 OEA if the start address is < 4096, not just == 0.
1605 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>
1607 * Makefile.in (maintainer-clean): New synonym for realclean.

1651 * core.c (core_add_data): First growth of bss was being put at
1652 wrong address (0) instead of &end.
1654 * core.c (core_add_stack, core_add_data): Was not handling case
1655 where bss/stack is grown across the current end-of-{bss,stack}.
1657 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
1659 * system.c (system_call): Fix SYS_break - was aligning bss to a
1660 page boundary instead of just an 8 byte one; On first call sbrk(0)
1663 Thu Aug 24 14:48:54 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1665 * Makefile.in (install): Fix install rule.
1667 Tue Aug 22 09:31:18 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1669 * system.c (system_call): Add read support.
1671 * main.c (main): -t sets trace_device_tree. Correct usage message
1674 * device_tree.c (update_memory_node_for_section): Make tracing
1675 output line up. If not code or readonly, assume that the section
1676 is a data section and has read/write permissions. Add readonly
1679 * core.c (create_core_from_addresses): Print end address in traces
1680 and make tracing output line up.
1682 * Makefile.in: Rewrite from Makefile to work with the Cygnus
1683 environment, and support compiling in a different directory than
1684 the sources reside in.
1686 * ppc-endian.h: Rename from endian.h so that it doesn't get
1687 confused with /usr/include/sys/endian.h on Linux. Add Linux
1690 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
1691 Include ppc-endian.h, not endian.h.
1693 * basics.h (sysdep.h): Include sysdep.h that configure makes.
1694 Include ppc-endian.h, not endian.h.
1696 * std-config.h: Rename from ppc-config. Put #ifndefs around most
1697 configuration macros, so they can be overridden via CFLAGS. By
1698 default, turn off tracing.
1700 * configure.in: Clone from other simulator targets.
1701 * configure: Generate via autoconf from configure.in.
1703 Sat Aug 19 09:05:32 1995 Andrew Cagney <cagney@highland.com.au>
1705 * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
1707 * interrupts.c (data_storage_interrupt): allow stack to grow by
1708 upto one MB per increment.
1710 * ppc-instructions: divw was computing rA / rA not rA / rB
1712 * main.c (main): really stupid. Wasn't exiting with correct status
1714 Fri Aug 18 00:38:01 1995 Andrew Cagney <cagney@highland.com.au>
1716 * system.c (system_call): add system calls kill(2) and getpid(2).
1718 * main.c (main): Check/return exit status when simulation
1721 Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney@highland.com.au>
1723 * device_tree.c (create_option_device_node): Alignment rules (at
1724 least for the moment) now are for strict alignment only for LE OEA
1725 mode. (Because of compiler problems).
1727 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
1729 Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
1731 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
1734 * system.c (system_call): didn't page align break argument before
1735 determining increment break increment.
1737 * psim/ppc: Re-arange entire directory structure so that
1738 everything lives in the one directory. While a pain for cleaning,
1739 makes building across multiple architectures much simpler.
1741 * devices.c, device_tree.c: Added code that provides a simple
1742 illustration of how an interrupt control device could be
1745 * devices.c: Added code so that the dumb console device can read
1746 (from stdin) as well as write to stdout.
