722 instruction.s. Signal illegal instruciton if data cache block
723 invalidate is issued from problem state.
725 * igen.c (max_model_fields_len): New static to keep track of the
726 max size for the model specific fields.
727 (model_c_insn): Use max_model_fields_len to size fields.

741 * inline.{c,h}: Ditto.
742 * std-config.h: Ditto.
744 * configure{,.in}: Ditto.
745 * Makefile.in: Ditto.

752 * configure{,.in}: Add --enable-sim-model-issue option.
753 * Makefile.in: Add --enable-sim-model-issue flags.
754 * igen.c (lf_print_c_semantic): Add call to mon_issue here. Check
755 for WITH_MODEL_ISSUE.
756 * mon.c (mon_issue): Remove call to mon_issue_here.
758 * ppc-instructions: Move branch tracing to the actual branch
759 instructions, rather than testing it in model_issue. Add code to
760 code successful/unsuccessful branch predictions, and the number of
761 conditional branches that fell through.

830 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
833 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
835 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
836 inline.. Only problem being that with ppc-opcode-simple this gave
837 it the chance to inline all the idecode functions with potentially
838 disasterous results on a 16mb PC. For moment hobble INLINE.
840 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
843 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
844 Firstly make them errors and secondly remove the options gcc-245
849 * misc.c (zalloc), cpu.c (cpu_init), devices
850 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
851 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
852 sim_calls.c (zalloc) : replace bzero() with memset().
854 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
855 psim_write_register): replace bcopy() with memcpy().
857 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
859 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
860 force DEFAULT_INLINE to 0 rather then trusting the std
863 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
865 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
866 generation of switch entries in tables - treat the same as
867 cracking/semantic functions.
869 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
870 of a boolean switch statement (field zero or non-zero).
872 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
873 switch/table generation ability of igen.
875 * igen.c (idecode_switch_leaf): Fix code output when a switch
876 statement needs to look up a table.
878 * igen.c (idecode_declare_if_switch): New function called from
879 gen_idecode_c - need to declare any idecode switch functions
880 before they are used in idecode tables.
882 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
883 idecode_crack_insn): Add is_inline_function argument to code
884 printing cracker functions which indicates if STATIC_IDECODE or
885 STATIC_INLINE_IDECODE should be used for definition. For
886 idecode_crack_insn (which implies not duplicating/expanding) don't
887 declare function as inline - we assume that the only time this is
888 code is generated is when things are being tested. For
889 idecode_crack_leaf, make static (instead of INLINE) if the
890 instructions parent is a table as function will always be called
893 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
894 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
895 called directly, all others are called via a table.
897 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
898 semantics_h_insn, semantics_h_function,
899 lf_print_c_semantic_function, semantics_c_function): Add
900 is_inline_function argument to lf_print_semantic_function_header
901 to indicate if an inline or static function declaration/definition
902 should be output. Depending on situtation call accordingly:
903 functions (not instruction semantic routines) are always inline;
904 Semantic routines are made inline when there is no icache (cache
905 will contain the function address) and are duplicating (see above)
906 and the parent of the instruction is a switch statement.
908 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
909 and moved to insn_table_find_opcode_field.
911 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
913 * igen.c (model_c_insn): Suggestion - document the name of the
914 instruction on each line of the instruction model table.

918 * emul_netbsd.c (do_ioctl): Cleanup compilation.
920 * sim_callbacks.h (__attribute__): Only define if not defined (was
921 already defined on NetBSD host).

926 macro, indicates if the PowerPC's horrible XOR endian mode should
927 be suported. Add to configure and make.
929 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
930 (vm_instruction_map_read): If XOR endian, xor the address
931 with a value from an xor table (indexed by size of access).
933 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
934 set up xor table to xor if there is a conflict between the
935 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
936 check of suported change of endian mode from cpu.c to vm.c.
938 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
939 Hopefully added correct hack to handle XOR endian mode.
941 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
942 little endian mode, the model accepts miss aligned transfers.
944 FIXME: Need to create an `init' device that, during
945 initializatioin for XOR mode, it mushes (XOR address) all the dma
946 data before passing it on to the core for storage. Just like the
949 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
951 * devices.c (halt_io_write_buffer_callback): Use value written to
952 halt device to determine exit status. Thus allowing
953 success/failure of OEA tests.
955 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
957 * ppc-instructions (icbi): If icache present flush it.

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

969 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
971 * filter_filename.c, Makefile.in: Change so that only dependant on

1014 model so 604 is first.

1036 * igen.c (semantics_h_print_function): Emit STATIC_SEMANTICS
1037 instead of INLINE_SEMANTICS so that the compiler won't keep all of
1038 the semantic functions as inline RTL, given that the address of
1039 the function is taken which forces outline calls anyway.
1040 (lf_print_c_semantic_function_header): Ditto.
1041 (gen_semantics_h): Define STATIC_SEMANTICS as nothing if not
1043 (lf_print_c_cracker_function): Emit STATIC_IDECODE instead of

1282 (mon_issue): Call function_unit_issue if function units are
1284 (mon_print_info): Take psim * argument. Print out information
1285 from function_unit if available. Move read/write stats to always
1286 print, instead of printing if verbose > 1. Fix up plural
1289 * mon.h (mon_print_info): Update prototype.
1291 * psim.c (current_ppc_model): Add global variable.
1292 (psim_print_info): Pass system argument to mon_print_info.

1305 * table.c (config.h): Include config.h.
1307 * vm.c (om_virtual_to_real): Print pte_word_{0,1} so the compiler
1308 doesn't complain that they're unused.
1310 * vm_n.h (vm_data_map_read_N): Delete unused variable rval.
1314 * sim-endian.c (ppc-endian.c), sim-endian.h (ppc-endian.h):
1315 renameed. These files are target independant.
1316 * Makefile.in, basics.h: update for new name.
1318 * sim-endian.h (SWAP_N), sim-endian.c (_SWAP_1): Rename existing
1319 SWAP_<N> to _SWAP_<N> so that sim-endian.h can contain SWAP_N
1320 macro's as required.
1322 * sim-endian.c, sim-endian-n.h (new file): Move endian code into a
1323 debugable header file.
1325 * ppc-instructions (Byte-Reverse): Enable byte reverse
1326 instructions using SWAP_N macros.
1330 * Makefile.in (config.status): Remove references to config.make
1333 * config.{make,hdr}: Delete, no longer used.
1334 * build-psim: Ditto.
1338 * sim_calls.c (sim_open): Fix parsing of `target sim' options.

1341 of the string being entered into the tree.
1343 * psim.c (create_filed_device_tree): Not terminating string device
1346 * psim.c (psim_create): Use `env' instead of
1347 `environment-architecture' to be consistent with configure.
1348 Reconize user/uea, virtual/vea and operating/oea.
1352 * core.c: Rename to corefile.c
1353 * core.h: Rename to corefile.h
1354 * inline.c: Include corefile.h, renamed from core.h.
1355 * cpu.h: Include corefile.h, renamed from core.h
1356 * vm.c: Include corefile.h, renamed from core.h
1357 * corefile.c: Include corefile.h rather than core.h

1364 (corefile.o): Change dependencies to corefile.c, corefile.h.
1368 * ppc-instructions (data cache instructions): Make all data cache
1369 instructions nops instead of invalid instructions.
1371 * Makefile.in (CONFIG_CFLAGS): Add ALIGNMENT_CFLAGS and
1372 TIMEBASE_CFLAGS which weren't included.
1376 * Makefile.in: Uncomment built file dependencies.
1378 * configure.in: Rewrite --enable-sim switch handling to use the
1379 autoconf builtins so it works correctly if the configure or
1380 Makefile.in files are modified and make decides to rebuild
1381 Makefile. Also document all of the --enable-sim switches
1382 supported. Check whether getrusage and sys/resource.h are
1384 * config.in: Regenerate.
1385 * configure: Regenerate.
1386 * Makefile.in: Add support for all of the variables set with
1387 --enable-sim switches.
1389 * Makefile.in (clean): make clean now removes all built sources as
1392 * cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H,
1393 HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in
1394 the generated config.h.
1396 * device_tree.c: Ditto.
1399 * emul_netbsd.c: Ditto.
1404 * registers.c: Ditto.
1405 * sim_calls.c: Ditt.
1409 * main.c (main): Call psim_print_info with verbose == 2.
1411 * mon.c (mon_print_info): Align the cpu number and number of
1412 instructions fields. Do not print an instruction category if the
1413 CPU did not execute any of those instructions. Print out number
1414 of reads and writes. If getrusage is supported, print out number
1415 of simulated instructins per second.
1417 * configure.in: Add support for --enable-sim-opcode=stupid.
1418 * configure: Regenerate.
1422 * std-config (INLINE_DEVICE_TREE): Don't inline either of
1423 device_tree.c or devices.c. There is no significant gain.
1425 * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
1430 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
1431 functions to convert between target and igen internal bit numbers.
1432 Make IO go through these functions. Add -b (bit size) and -h (high
1433 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
1434 15 for a 16 bit instruction format with the msb given a number 15.
1438 * dgen.c (main): Was outputting optarg even when it was NULL.
1442 * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h,
1443 debug.c: Add tracing of load/store unit (virtual) with -t
1448 * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does
1449 not include things such as the time base and events.

1452 all environment switches for above.
1454 * psim.c (psim_create): ditto - new device tree node name is
1455 /options/environment-architecture with values user, virtual and
1460 * ppc-opcode-stupid: Third example of use of opcode table - this
1461 one expands all mtspr/mfspr and branch instructions. Appears to
1462 give about a 10% gain in performance if everything enabled. Also
1463 takes about 150mb of swap to build.
1467 * emul_netbsd.c (do_exit): Print arguments and close parenthesis
1468 if tracing, since exit doesn't go through emul_exit_call.
1469 (do_read): Print arguments if tracing.
1475 (do_sigprocmask): Replace trace with printing arguments if
1477 (do_ioctl): Print arguments if tracing.

1486 the directory prefix from a file.
1487 * filter_filename.h: New include file to declare filter_filename.
1489 * debug.h: Include filter_filename.h.
1490 (TRACE,DTRACE,ERROR): Use filter_filename on __FILE__.
1492 * misc.h: Include filter_filename.h.
1493 (ASSERT): Use filter_filename on __FILE__.
1495 * igen.c (lf_print_my_prefix): Use filter_filename on the filename
1498 * Makefile.in: Add filter_filename support.
1500 * ppc-instructions (dcbi, icbi): Make these NOPs rather than
1501 invalid instructions.
1503 * configure.in: Add support for more --enable-sim-* switches.
1504 Use config.make and config.hdr to write to Makefile and config.h
1505 respectively. Don't rewrite Makefile, just append to it.
1506 * configure: Regenerate.
1507 * config.{make,hdr}: New shell scripts.
1509 * Makefile.in: Remove all variables set by configure.in.
1510 (psim.o): Depend on $(BUILT_SRC) also.
1512 * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an
1513 integer, use 0, not NULL.
1517 * configure.in: Add support for --enable-sim-inline,
1518 --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex,
1519 --enable-sim-switch, --enable-sim-duplicate, --enable-sim-filter,
1520 and --enable-sim-endian switch to control various Makefile
1522 * configure: Regenerate from configure.in.
1523 * Makefile.in: Add various Make variables that the various
1526 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
1527 and optimizing by default.
1531 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1532 make them functions again. Appears 2.6.3 is confused by just a
1537 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
1539 * psim.c (psim_create): Not correctly checking that runtime
1540 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1541 matched the compiled in ones.
1543 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1544 trace_semantics is now different to trace_idecode, the former
1549 * ppc-instructions (mtsrin): Missing instruction
1550 * ppc-instructions (mfsrin): Missing instruction
1551 * ppc-instructions (eieio): Missing instruction
1555 * build-psim: New shell script - see internals for usage,
1556 simplifies the process of building custom simulators.
1560 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1561 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1562 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1563 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1564 the instruction or data critical paths.
1566 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1567 the inclusion of device_tree.c/emul_generic.c.
1571 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
1572 system.[hc]. Start of suport for multiple emulations and
1573 emulation state (os_emul object).
1575 * emul_generic.[hc]: Start of code to implement proper system call
1580 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1581 the processor is started. Fixes problem of registers being
1582 undefined when restarting from within gdb.
1584 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1585 instruction cache (if present). Fixes problem of cpu caching gdb
1586 breakpoint instructions.
1588 FIXME: PSIM sometimes aborts calling error(), it should instead
1589 call sim_error() say which takes care of housekeeping such as
1590 saving the CIA before calling error.
1592 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1593 used when restarting a simulation because the latter has the
1594 unwanted side effect (well I as a kernel hacker think it is) of
1595 performing an isync when the instruction stream doesn't contain
1600 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1601 monitoring module. Counts both instructions issued and
1604 * NOTE: mon does not contain to count instruction loads as this
1605 information is already available from the mon_issue() hook.
1607 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1609 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1610 a common monitor to each of the cpus. Delete
1611 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1612 replaced by copied code in mon.[hc].
1616 * sim_calls.c, main.c, psim.c (psim_create): always create
1617 `WITH_SMP' cpus. The actual number of CPU's active in a
1618 simulation run is taken from the device node: /init/smp (an
1619 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1623 * system.c: More system call emulation. If code appears NetBSD
1624 specific, make conditional to being compiled on a NetBSD system
1629 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1630 lf.[ch](new), table.[ch](new): Split into two generators - igen
1631 that outputs the instruction tables and dgen that outputs the spr
1632 tables. Add -f (filter out) flag to igen to filter out certain
1633 instructions (ex 64 bit ones) from the created tables. Include
1634 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1637 * NOTE: igen, since it was originally written for the
1638 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1640 * Makefile.in, std-config.h, ppc-cache-rules(new),
1641 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1642 cache-rule and opcode-rule tables from macros found std-config.h.
1643 Delete corresponding macro's from std-config.h.
1645 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1646 an table of all the instructions. Code to output a type
1647 enumerating all the instructin names.
1649 * igen.c(lf_print_c_semantic): Move call to increment instruction
1650 counter so that it occures _after_ the instruction has been fully
1651 validated, was double counting illegal/invalid instructions. Add
1652 conditional so only compiled in when WITH_PROFILE enabled (enabled
1655 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1656 itable.h, count individual instruction types not just total,
1657 adjust reporting functions to output this.
1659 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
1660 Had 32./ instead of 31./
1662 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1663 bitrot - updated to use newer CR register operators.
1665 * ppc-instructions (64bit Floating Convert from Integer
1666 Doubleword): Correct call to Round_Float().
1670 * basics.h: #include "sim_callbacks.h" earlier so that its
1671 prototypes are declared in all other header files.
1673 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1674 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1677 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1678 Add size of buffer argument to functions writing a string into a
1679 buffer. Check for buffer overflow.
1683 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1684 of each device. Make parameter names consistent so macros work.
1685 Use macro's in device functions.
1687 * device_tree.c, devices.h, devices.c: include path to device in a
1688 devices node when creating it.
1690 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
1692 * core.c: add tracing of core-device, adjust parameter names in
1693 core functions to be consistent with those in devices*.
1697 * debug.h, debug.c (trace_option): New function. Parses the trace
1698 option, updating the trace array.
1700 * debug.h, debug.c (trace_usage): New function. Outputs the list
1701 of all possible trace options.
1703 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1704 parse trace options specified with the simpler -t flag. Adjust
1707 * FIXME: basic parsing of command line options is still duplicated
1708 by main.c and sim_calls.c
1712 * Makefile.in (clean): Delete *.i and *.out files.
1714 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1715 macros for either assignment or return. Fix SWAP_8 to use a
1716 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1717 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1718 that hardwired swapping on/off, let optimizer delete dead code.
1720 * main.c (main): Add printf that we caught a signal and print out
1721 the failing address.
1725 * Makefile.in: Remove tabs from otherwise empty line.
1726 Confuses many non-GNU versions of "make".
1730 * Makefile.in (clean): Delete files produced by gen.
1734 * gen.c (lf_print_c_semantic_function): Move counting # of
1735 instructions here so it works with caching.
1736 (gen_idecode_c): Move from here.
1740 * gen.c, ppc-instructions, psim.c: Fix code for generating
1741 cracking instruction cache. Delete the code that cached just the
1742 result from doing an instruction lookup - this ran slower than no
1747 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1749 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1750 TCL when gdb is linked with the simulator.
1751 * debug.c (ppc_trace): Ditto.
1752 * sim_calls.c (sim_open): Change trace -> ppc_trace.
1753 * main.c (main): Ditto.
1755 * cpu.c (cpu_add_commas): Remove extra static.
1759 * Makefile.in (psim.o): Now that inlines are turned on, make
1760 psim.o depend on all sources.
1762 * cpu.c (cpu_add_commas): New function to format a long with
1764 (cpu_print_info): Use it to print number_of_insns.
1766 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1768 (ENDIAN_N): If both target and host byte orders are known, don't
1769 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1771 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1772 to allow target specific H2T_n/T2H_n macros to be used.
1773 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1774 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1775 of the 3 instruction sequence that runs on 386s.
1777 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1778 specified on the compile line.
1779 (WITH_BSWAP): If not defined, define as 0.
1781 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1782 default inline support. Pass INLINE_CFLAGS when compiling.
1784 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1785 INLINE_DEVICES since GCC doesn't like inline functions that
1786 accept variable arguments.
1787 (stack_ioctl_callback): Make function just static because GCC
1788 doesn't like inline functions that accept variable arguments.
1790 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1792 * inline.c: Correct pathnames of included C files to match current
1795 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1796 non-zero, define STATIC_DEVICES to be static.
1798 * std-config.h (INLINE): If GNU C and optimizing, define this as
1800 (DEFAULT_INLINE): If not defined, define as 0.
1801 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1802 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1803 ({SPREG,IDECODE}_INLINE): Ditto.
1807 * ppc-instructions: Initial cut of floating point suport added.
1808 Of note include - use of host IEEE floating point instructions,
1809 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1810 currently a pretty sight.
1812 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1813 merge into core.h, core.c, core_n.h. The type memory_map replaced
1814 with core_map. This removes a level of pointer indirection when
1815 translating an address.
1817 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1819 * Makefile.in et.al (sorry): tweek to use new core, core_map and
1824 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
1825 most of the other functions in sim_calls.c.
1827 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1828 Add macros to better cover up `generic' code. Makes it possible
1829 to step through the generic code!
1831 * vm.c, vm_n.h, Makefile.in: ditto
1835 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1836 callback interface so that there is a read/write buffer but no
1837 read/write_word. VEA default memory read/write handler sometimes
1838 couldn't resolve an access and of those some were for a memory
1839 fault and some were because gdb was making a bogus request.
1841 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1842 eliminate transfer_mode (raw or cooked) parameter from read/write
1847 * ppc-instructions (fmul, fmuls): correct instruction format - had
1852 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1853 scand_*): new functions to parse/print fields in device names
1854 while hiding any machine dependency.
1856 * devices.c, psim.c: Change the stack init code so that it is
1857 handled by a device. Arguments passed across using a device ioctl
1860 * devices.h, devices.c: device ioctl callback changed to allow a
1861 variable number of arguments. This gives greater flexability and
1862 greater chance of bugs.
1866 * main.c (printf_filtered, error): Missing va_end() to close off
1867 variable argument use.
1869 * Makefile.in (tmp-gencode): comment out hack to get around some
1870 versions of make not handling files being created as side-effects.
1872 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
1873 alternative file name to use in output files for things like #line
1876 Makefile.in (tmp-gencode): Use gen -n so that debug info is
1879 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
1884 * sim_calls.c (sim_set_callbacks): Define new function.
1888 * psim.c (psim_print_info): Print exit status or signal number.
1892 * cpu.c (struct _cpu): Add number_of_insns field to trace how many
1893 instructions are executed.
1894 (cpu_increment_number_of_insns): New function to increment the
1895 number of instructions issued.
1896 (cpu_get_number_of_insns): New function to return the number of
1897 instructions issued.
1898 (cpu_print_info): New function to print cpu related information.
1899 At present, print the number of instructions executed.
1901 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
1904 * psim.c (psim_print_info): New function to iterate over each of
1905 the CPU's calling cpu_print_info.
1907 * psim.h,cpu.h: Add new declarations.
1909 * sim_calls.c (sim_open): Add argument processing to add the same
1910 switches main.c accepts for the standalone processor.
1911 (sim_close): Call psim_print_info if -I.
1913 * main.c (main): Add comment saying to update sim_calls.c when
1914 adding switches. Add -I to call psim_print_info when done.
1915 (usage): Update usage message.
1919 * main.c (printf_filtered): Correct to match new prototype.
1923 * sim_callbacks.h (printf_filtered): Correct prototype.
1927 * device_tree.c (OEA_MEMORY_SIZE): Define if not defined to
1929 (clayton_memory_size): Define as OEA_MEMORY_SIZE.
1931 * std-config.h (WITH_TRACE): Default to 1 now.
1933 * psim.c (write_stack_arguments): Don't write any stack arguments
1936 * main.c (main): Switch to using getopt. Make -p also set
1937 trace_semantics. Make -a turn on all trace flags. Make -C turn
1940 * device_tree.c (create_option_device_node): Assume a program is
1941 OEA if the start address is < 4096, not just == 0.
1945 * Makefile.in (maintainer-clean): New synonym for realclean.
1949 * registers.c (register_description): Add gdb synonyms for cr
1954 * Makefile.in (install): Don't install in $(tooldir).
1956 * configure.in: Call AC_CONFIG_HEADER. Don't try to use
1957 bfd/hosts/*.h file or bfd/config/*.mh file. Call AC_PROG_CC and
1958 AC_PROG_RANLIB. Substitute in values for CFLAGS, HDEFINES, AR,
1959 and CC_FOR_BUILD. Call AC_CHECK_HEADERS for various header files.
1960 Touch stamp.h if creating config.h.
1961 * configure: Rebuild.
1962 * config.in: New file, created by autoheader.
1963 * Makefile.in (AR): Define as @AR@.
1964 (CC): New variable, defined as @CC@.
1965 (CFLAGS): Define as @CFLAGS@.
1966 (CC_FOR_BUILD): New variable, defined as @CC_FOR_BUILD@.
1967 (RANLIB): Define as @RANLIB@.
1968 (HDEFINES, TDEFINES): New variables.
1969 (@host_makefile_frag@): Remove.
1970 (mostlyclean): Make the same as clean, not distclean.
1971 (clean): Remove config.log.
1972 (distclean): Remove config.h and stamp-h.
1973 (Makefile): Don't depend upon @frags@. Just rebuild Makefile when
1974 invoking config.status.
1975 (config.h, stamp-h): New targets.
1976 (gen, gen.o): Build with CC_FOR_BUILD, not CC.
1977 (ppc-config.h): Rename from old config.h build.
1978 * (basics.h,gen.c,ppc-endian.c,psim.c): Include ppc-config.h.
1982 * configure{,.in}: Don't include sysdep.h from bfd, since bfd no
1984 * basics.h (sysdep.h): Don't include it.
1985 * Makefile.in (BASICS_H): Remove sysdep.h.
1989 * core.c (core_add_data): First growth of bss was being put at
1990 wrong address (0) instead of &end.
1992 * core.c (core_add_stack, core_add_data): Was not handling case
1993 where bss/stack is grown across the current end-of-{bss,stack}.
1997 * system.c (system_call): Fix SYS_break - was aligning bss to a
1998 page boundary instead of just an 8 byte one; On first call sbrk(0)
2003 * Makefile.in (install): Fix install rule.
2007 * system.c (system_call): Add read support.
2009 * main.c (main): -t sets trace_device_tree. Correct usage message
2012 * device_tree.c (update_memory_node_for_section): Make tracing
2013 output line up. If not code or readonly, assume that the section
2014 is a data section and has read/write permissions. Add readonly
2017 * core.c (create_core_from_addresses): Print end address in traces
2018 and make tracing output line up.
2020 * Makefile.in: Rewrite from Makefile to work with the Cygnus
2021 environment, and support compiling in a different directory than
2022 the sources reside in.
2024 * ppc-endian.h: Rename from endian.h so that it doesn't get
2025 confused with /usr/include/sys/endian.h on Linux. Add Linux
2028 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
2029 Include ppc-endian.h, not endian.h.
2031 * basics.h (sysdep.h): Include sysdep.h that configure makes.
2032 Include ppc-endian.h, not endian.h.
2034 * std-config.h: Rename from ppc-config. Put #ifndefs around most
2035 configuration macros, so they can be overridden via CFLAGS. By
2036 default, turn off tracing.
2038 * configure.in: Clone from other simulator targets.
2039 * configure: Generate via autoconf from configure.in.
2043 * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
2045 * interrupts.c (data_storage_interrupt): allow stack to grow by
2046 upto one MB per increment.
2048 * ppc-instructions: divw was computing rA / rA not rA / rB
2050 * main.c (main): really stupid. Wasn't exiting with correct status
2054 * system.c (system_call): add system calls kill(2) and getpid(2).
2056 * main.c (main): Check/return exit status when simulation
2061 * device_tree.c (create_option_device_node): Alignment rules (at
2062 least for the moment) now are for strict alignment only for LE OEA
2063 mode. (Because of compiler problems).
2065 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
2069 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
2072 * system.c (system_call): didn't page align break argument before
2073 determining increment break increment.
2075 * psim/ppc: Re-arange entire directory structure so that
2076 everything lives in the one directory. While a pain for cleaning,
2077 makes building across multiple architectures much simpler.
2079 * devices.c, device_tree.c: Added code that provides a simple
2080 illustration of how an interrupt control device could be
2083 * devices.c: Added code so that the dumb console device can read
2084 (from stdin) as well as write to stdout.
