593 Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
595 * Makefile.in (devices.o, main.o): Update dependency.
597 * igen.c (gen_model_h): Use correct variable in loop.
598 (gen_model_c): Use strcmp, strcasecmp.
599 (gen_model_c): Use EXTERN_MODEL for arrays.
600 (gen_model_h): Use STATIC_MODEL for arrays.

610 (gen_itable_h,itable_c_insn): Ditto.
611 (model support): Move model support around, add support for
612 model-data, model-internal. Use annex field for model-macros
615 * configure.in (--enable-sim-inline): If --enable-sim-inline=no,
616 also define INLINE as nothing.
617 * configure: Regenerate.
619 * std-config.h (INLINE): Rather than nuking INLINE, only define it
620 as __inline__ if any of the INLINE flags are non-zero.

628 * cpu.c (cpu_get_time_base): Fix calculation of current value of
631 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
632 m[tf]tb with m[tf]spr.
634 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
637 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
639 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
640 inline.. Only problem being that with ppc-opcode-simple this gave
641 it the chance to inline all the idecode functions with potentially
642 disasterous results on a 16mb PC. For moment hobble INLINE.
644 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
647 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
648 Firstly make them errors and secondly remove the options gcc-245
651 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
653 * misc.c (zalloc), cpu.c (cpu_init), devices
654 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
655 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
656 sim_calls.c (zalloc) : replace bzero() with memset().
658 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
659 psim_write_register): replace bcopy() with memcpy().
661 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
663 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
664 force DEFAULT_INLINE to 0 rather then trusting the std
667 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
669 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
670 generation of switch entries in tables - treat the same as
671 cracking/semantic functions.
673 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
674 of a boolean switch statement (field zero or non-zero).
676 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
677 switch/table generation ability of igen.
679 * igen.c (idecode_switch_leaf): Fix code output when a switch
680 statement needs to look up a table.
682 * igen.c (idecode_declare_if_switch): New function called from
683 gen_idecode_c - need to declare any idecode switch functions
684 before they are used in idecode tables.
686 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
687 idecode_crack_insn): Add is_inline_function argument to code
688 printing cracker functions which indicates if STATIC_IDECODE or
689 STATIC_INLINE_IDECODE should be used for definition. For
690 idecode_crack_insn (which implies not duplicating/expanding) don't
691 declare function as inline - we assume that the only time this is
692 code is generated is when things are being tested. For
693 idecode_crack_leaf, make static (instead of INLINE) if the
694 instructions parent is a table as function will always be called
697 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
698 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
699 called directly, all others are called via a table.
701 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
702 semantics_h_insn, semantics_h_function,
703 lf_print_c_semantic_function, semantics_c_function): Add
704 is_inline_function argument to lf_print_semantic_function_header
705 to indicate if an inline or static function declaration/definition
706 should be output. Depending on situtation call accordingly:
707 functions (not instruction semantic routines) are always inline;
708 Semantic routines are made inline when there is no icache (cache
709 will contain the function address) and are duplicating (see above)
710 and the parent of the instruction is a switch statement.
712 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
713 and moved to insn_table_find_opcode_field.
715 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
717 * igen.c (model_c_insn): Suggestion - document the name of the
718 instruction on each line of the instruction model table.
720 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
722 * emul_netbsd.c (do_ioctl): Cleanup compilation.
724 * sim_callbacks.h (__attribute__): Only define if not defined (was
725 already defined on NetBSD host).

730 macro, indicates if the PowerPC's horrible XOR endian mode should
731 be suported. Add to configure and make.
733 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
734 (vm_instruction_map_read): If XOR endian, xor the address
735 with a value from an xor table (indexed by size of access).
737 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
738 set up xor table to xor if there is a conflict between the
739 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
740 check of suported change of endian mode from cpu.c to vm.c.
742 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
743 Hopefully added correct hack to handle XOR endian mode.
745 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
746 little endian mode, the model accepts miss aligned transfers.
748 FIXME: Need to create an `init' device that, during
749 initializatioin for XOR mode, it mushes (XOR address) all the dma
750 data before passing it on to the core for storage. Just like the
753 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
755 * devices.c (halt_io_write_buffer_callback): Use value written to
756 halt device to determine exit status. Thus allowing
757 success/failure of OEA tests.
759 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
761 * ppc-instructions (icbi): If icache present flush it.

765 * devices.c (htab_init_callback): Add code to create htab/pte.
767 * devices.c (dma_file, file_init_callback, htab_init_callback):
768 New function - Dma the named file into memory at the specified

773 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
775 * filter_filename.c, Makefile.in: Change so that only dependant on
776 a very limited nr of files. Stops an unnecessary dependency.
778 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
780 * core.c (core_map_find_mapping): Use cpu_halt rather than error
781 to abort an access to an undefined address.
783 Sun Nov 12 07:58:09 1995 Michael Meissner <meissner@tiktok.cygnus.com>

821 * sim_calls.c (sim_open): Ditto.
822 * sim_calls.c, Makefile.in: sim_calls.c now includes cpu.h.

840 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
841 instead of INLINE_SEMANTICS so that the compiler won't keep all of
842 the semantic functions as inline RTL, given that the address of
843 the function is taken which forces outline calls anyway.

1176 TIMEBASE_CFLAGS which weren't included.
1178 Thu Nov 2 08:54:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1180 * Makefile.in: Uncomment built file dependencies.
1182 * configure.in: Rewrite --enable-sim switch handling to use the
1183 autoconf builtins so it works correctly if the configure or
1184 Makefile.in files are modified and make decides to rebuild
1185 Makefile. Also document all of the --enable-sim switches
1186 supported. Check whether getrusage and sys/resource.h are
1188 * config.in: Regenerate.
1189 * configure: Regenerate.
1190 * Makefile.in: Add support for all of the variables set with
1191 --enable-sim switches.

1203 * emul_netbsd.c: Ditto.
1208 * registers.c: Ditto.
1209 * sim_calls.c: Ditt.
1213 * main.c (main): Call psim_print_info with verbose == 2.
1215 * mon.c (mon_print_info): Align the cpu number and number of
1216 instructions fields. Do not print an instruction category if the
1217 CPU did not execute any of those instructions. Print out number
1218 of reads and writes. If getrusage is supported, print out number
1219 of simulated instructins per second.
1221 * configure.in: Add support for --enable-sim-opcode=stupid.
1222 * configure: Regenerate.
1224 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
1226 * std-config (INLINE_DEVICE_TREE): Don't inline either of
1227 device_tree.c or devices.c. There is no significant gain.
1229 * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
1232 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
1234 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
1235 functions to convert between target and igen internal bit numbers.
1236 Make IO go through these functions. Add -b (bit size) and -h (high
1237 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
1238 15 for a 16 bit instruction format with the msb given a number 15.
1240 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
1242 * dgen.c (main): Was outputting optarg even when it was NULL.
1244 Tue Oct 31 23:48:33 1995 Andrew Cagney <cagney@highland.com.au>
1246 * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h,
1247 debug.c: Add tracing of load/store unit (virtual) with -t
1250 Tue Oct 31 21:44:01 1995 Andrew Cagney <cagney@highland.com.au>
1252 * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does
1253 not include things such as the time base and events.

1256 all environment switches for above.
1258 * psim.c (psim_create): ditto - new device tree node name is

1262 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
1264 * ppc-opcode-stupid: Third example of use of opcode table - this
1265 one expands all mtspr/mfspr and branch instructions. Appears to
1266 give about a 10% gain in performance if everything enabled. Also
1267 takes about 150mb of swap to build.
1269 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1271 * emul_netbsd.c (do_exit): Print arguments and close parenthesis
1272 if tracing, since exit doesn't go through emul_exit_call.

1324 and --enable-sim-endian switch to control various Makefile
1326 * configure: Regenerate from configure.in.
1327 * Makefile.in: Add various Make variables that the various
1330 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
1331 and optimizing by default.
1333 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
1335 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1336 make them functions again. Appears 2.6.3 is confused by just a
1339 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1341 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
1343 * psim.c (psim_create): Not correctly checking that runtime
1344 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1345 matched the compiled in ones.
1347 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1348 trace_semantics is now different to trace_idecode, the former
1351 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
1353 * ppc-instructions (mtsrin): Missing instruction
1354 * ppc-instructions (mfsrin): Missing instruction
1355 * ppc-instructions (eieio): Missing instruction
1357 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
1359 * build-psim: New shell script - see internals for usage,
1360 simplifies the process of building custom simulators.
1362 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
1364 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1365 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1366 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1367 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1368 the instruction or data critical paths.
1370 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1371 the inclusion of device_tree.c/emul_generic.c.
1373 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1375 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

1382 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
1384 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1385 the processor is started. Fixes problem of registers being
1386 undefined when restarting from within gdb.
1388 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1389 instruction cache (if present). Fixes problem of cpu caching gdb
1390 breakpoint instructions.
1392 FIXME: PSIM sometimes aborts calling error(), it should instead
1393 call sim_error() say which takes care of housekeeping such as
1394 saving the CIA before calling error.
1396 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1397 used when restarting a simulation because the latter has the
1398 unwanted side effect (well I as a kernel hacker think it is) of
1399 performing an isync when the instruction stream doesn't contain
1402 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1404 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1405 monitoring module. Counts both instructions issued and
1408 * NOTE: mon does not contain to count instruction loads as this
1409 information is already available from the mon_issue() hook.
1411 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1413 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1414 a common monitor to each of the cpus. Delete
1415 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1416 replaced by copied code in mon.[hc].
1418 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1420 * sim_calls.c, main.c, psim.c (psim_create): always create
1421 `WITH_SMP' cpus. The actual number of CPU's active in a
1422 simulation run is taken from the device node: /init/smp (an
1423 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1425 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1427 * system.c: More system call emulation. If code appears NetBSD
1428 specific, make conditional to being compiled on a NetBSD system
1431 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
1433 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1434 lf.[ch](new), table.[ch](new): Split into two generators - igen
1435 that outputs the instruction tables and dgen that outputs the spr
1436 tables. Add -f (filter out) flag to igen to filter out certain
1437 instructions (ex 64 bit ones) from the created tables. Include
1438 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1441 * NOTE: igen, since it was originally written for the
1442 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1444 * Makefile.in, std-config.h, ppc-cache-rules(new),
1445 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1446 cache-rule and opcode-rule tables from macros found std-config.h.
1447 Delete corresponding macro's from std-config.h.
1449 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1450 an table of all the instructions. Code to output a type
1451 enumerating all the instructin names.
1453 * igen.c(lf_print_c_semantic): Move call to increment instruction
1454 counter so that it occures _after_ the instruction has been fully
1455 validated, was double counting illegal/invalid instructions. Add
1456 conditional so only compiled in when WITH_PROFILE enabled (enabled
1459 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1460 itable.h, count individual instruction types not just total,
1461 adjust reporting functions to output this.
1463 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
1464 Had 32./ instead of 31./
1466 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1467 bitrot - updated to use newer CR register operators.
1469 * ppc-instructions (64bit Floating Convert from Integer
1470 Doubleword): Correct call to Round_Float().
1472 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1474 * basics.h: #include "sim_callbacks.h" earlier so that its
1475 prototypes are declared in all other header files.
1477 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1478 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1481 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1482 Add size of buffer argument to functions writing a string into a
1483 buffer. Check for buffer overflow.
1485 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1487 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1488 of each device. Make parameter names consistent so macros work.
1489 Use macro's in device functions.
1491 * device_tree.c, devices.h, devices.c: include path to device in a
1492 devices node when creating it.
1494 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
1496 * core.c: add tracing of core-device, adjust parameter names in
1497 core functions to be consistent with those in devices*.
1499 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
1501 * debug.h, debug.c (trace_option): New function. Parses the trace
1502 option, updating the trace array.
1504 * debug.h, debug.c (trace_usage): New function. Outputs the list
1505 of all possible trace options.
1507 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1508 parse trace options specified with the simpler -t flag. Adjust
1511 * FIXME: basic parsing of command line options is still duplicated
1512 by main.c and sim_calls.c
1514 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1516 * Makefile.in (clean): Delete *.i and *.out files.
1518 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1519 macros for either assignment or return. Fix SWAP_8 to use a
1520 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1521 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1522 that hardwired swapping on/off, let optimizer delete dead code.
1524 * main.c (main): Add printf that we caught a signal and print out
1525 the failing address.
1527 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1529 * Makefile.in: Remove tabs from otherwise empty line.
1530 Confuses many non-GNU versions of "make".

1534 * Makefile.in (clean): Delete files produced by gen.
1536 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1538 * gen.c (lf_print_c_semantic_function): Move counting # of
1539 instructions here so it works with caching.
1540 (gen_idecode_c): Move from here.
1542 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1544 * gen.c, ppc-instructions, psim.c: Fix code for generating
1545 cracking instruction cache. Delete the code that cached just the
1546 result from doing an instruction lookup - this ran slower than no
1549 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1551 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1553 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1554 TCL when gdb is linked with the simulator.
1555 * debug.c (ppc_trace): Ditto.
1556 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1557 * main.c (main): Ditto.

1563 * Makefile.in (psim.o): Now that inlines are turned on, make
1564 psim.o depend on all sources.
1566 * cpu.c (cpu_add_commas): New function to format a long with
1568 (cpu_print_info): Use it to print number_of_insns.
1570 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1572 (ENDIAN_N): If both target and host byte orders are known, don't
1573 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1575 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1576 to allow target specific H2T_n/T2H_n macros to be used.
1577 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1578 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1579 of the 3 instruction sequence that runs on 386s.
1581 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1582 specified on the compile line.
1583 (WITH_BSWAP): If not defined, define as 0.
1585 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1586 default inline support. Pass INLINE_CFLAGS when compiling.
1588 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1589 INLINE_DEVICES since GCC doesn't like inline functions that
1590 accept variable arguments.
1591 (stack_ioctl_callback): Make function just static because GCC
1592 doesn't like inline functions that accept variable arguments.
1594 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1596 * inline.c: Correct pathnames of included C files to match current
1599 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1600 non-zero, define STATIC_DEVICES to be static.
1602 * std-config.h (INLINE): If GNU C and optimizing, define this as
1604 (DEFAULT_INLINE): If not defined, define as 0.
1605 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1606 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1607 ({SPREG,IDECODE}_INLINE): Ditto.
1609 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1611 * ppc-instructions: Initial cut of floating point suport added.
1612 Of note include - use of host IEEE floating point instructions,
1613 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1614 currently a pretty sight.
1616 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1617 merge into core.h, core.c, core_n.h. The type memory_map replaced
1618 with core_map. This removes a level of pointer indirection when
1619 translating an address.
1621 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1623 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1628 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1629 most of the other functions in sim_calls.c.
1631 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1632 Add macros to better cover up `generic' code. Makes it possible
1633 to step through the generic code!
1635 * vm.c, vm_n.h, Makefile.in: ditto
1637 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1639 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1640 callback interface so that there is a read/write buffer but no
1641 read/write_word. VEA default memory read/write handler sometimes
1642 couldn't resolve an access and of those some were for a memory
1643 fault and some were because gdb was making a bogus request.
1645 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1646 eliminate transfer_mode (raw or cooked) parameter from read/write
1649 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1651 * ppc-instructions (fmul, fmuls): correct instruction format - had
1654 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1656 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
