572 * sim-endian.h (SWAP_N), sim-endian-n.h, sim-endian.c: How
573 embarasing - fix yet another bug in the swap code! Simplify

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

746 defined in lf_print_c_extraction.
747 (main): Recognize -R.

804 Sun Nov 19 23:00:52 1995 Michael Meissner <meissner@tiktok.cygnus.com>
806 * ppc-instructions (model data, model_busy): Rather than using a
807 bit mask for the busy units, just use a char array. Also, only
808 support 2 function units an insn can use, rather than a loop.
810 Fri Nov 17 14:08:08 1995 Michael Meissner <meissner@tiktok.cygnus.com>
812 * table.c (table_entry_read): Move setting entry->line_nr to after

817 before calling the model functions.
819 * debug.c (trace_descriptor): Add trace_model support.

872 * Makefile.in: Ditto.

882 for WITH_MODEL_ISSUE.
883 * mon.c (mon_issue): Remove call to mon_issue_here.
885 * ppc-instructions: Move branch tracing to the actual branch
886 instructions, rather than testing it in model_issue. Add code to
887 code successful/unsuccessful branch predictions, and the number of
888 conditional branches that fell through.
890 Wed Nov 15 17:32:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
892 * cpu.h (cpu_model): Add declaration.

960 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
962 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
963 inline.. Only problem being that with ppc-opcode-simple this gave
964 it the chance to inline all the idecode functions with potentially
965 disasterous results on a 16mb PC. For moment hobble INLINE.
967 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
970 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
971 Firstly make them errors and secondly remove the options gcc-245
974 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
976 * misc.c (zalloc), cpu.c (cpu_init), devices
977 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
978 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
979 sim_calls.c (zalloc) : replace bzero() with memset().
981 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
982 psim_write_register): replace bcopy() with memcpy().
984 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
986 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
987 force DEFAULT_INLINE to 0 rather then trusting the std
990 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
992 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
993 generation of switch entries in tables - treat the same as
994 cracking/semantic functions.
996 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
997 of a boolean switch statement (field zero or non-zero).
999 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
1000 switch/table generation ability of igen.
1002 * igen.c (idecode_switch_leaf): Fix code output when a switch
1003 statement needs to look up a table.
1005 * igen.c (idecode_declare_if_switch): New function called from
1006 gen_idecode_c - need to declare any idecode switch functions
1007 before they are used in idecode tables.
1009 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
1010 idecode_crack_insn): Add is_inline_function argument to code
1011 printing cracker functions which indicates if STATIC_IDECODE or
1012 STATIC_INLINE_IDECODE should be used for definition. For
1013 idecode_crack_insn (which implies not duplicating/expanding) don't
1014 declare function as inline - we assume that the only time this is
1015 code is generated is when things are being tested. For
1016 idecode_crack_leaf, make static (instead of INLINE) if the
1017 instructions parent is a table as function will always be called
1020 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
1021 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
1022 called directly, all others are called via a table.
1024 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
1025 semantics_h_insn, semantics_h_function,
1026 lf_print_c_semantic_function, semantics_c_function): Add
1027 is_inline_function argument to lf_print_semantic_function_header
1028 to indicate if an inline or static function declaration/definition
1029 should be output. Depending on situtation call accordingly:
1030 functions (not instruction semantic routines) are always inline;
1031 Semantic routines are made inline when there is no icache (cache
1032 will contain the function address) and are duplicating (see above)
1033 and the parent of the instruction is a switch statement.
1035 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
1036 and moved to insn_table_find_opcode_field.
1038 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
1040 * igen.c (model_c_insn): Suggestion - document the name of the
1041 instruction on each line of the instruction model table.
1043 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
1045 * emul_netbsd.c (do_ioctl): Cleanup compilation.
1047 * sim_callbacks.h (__attribute__): Only define if not defined (was
1048 already defined on NetBSD host).
1050 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1052 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
1053 macro, indicates if the PowerPC's horrible XOR endian mode should
1054 be suported. Add to configure and make.
1056 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
1057 (vm_instruction_map_read): If XOR endian, xor the address
1058 with a value from an xor table (indexed by size of access).
1060 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
1061 set up xor table to xor if there is a conflict between the
1062 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
1063 check of suported change of endian mode from cpu.c to vm.c.
1065 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
1066 Hopefully added correct hack to handle XOR endian mode.
1068 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
1069 little endian mode, the model accepts miss aligned transfers.
1071 FIXME: Need to create an `init' device that, during
1072 initializatioin for XOR mode, it mushes (XOR address) all the dma
1073 data before passing it on to the core for storage. Just like the
1076 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
1078 * devices.c (halt_io_write_buffer_callback): Use value written to
1079 halt device to determine exit status. Thus allowing
1080 success/failure of OEA tests.
1082 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
1084 * ppc-instructions (icbi): If icache present flush it.
1086 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1088 * devices.c (htab_init_callback): Add code to create htab/pte.
1090 * devices.c (dma_file, file_init_callback, htab_init_callback):
1091 New function - Dma the named file into memory at the specified
1094 * device_tree.h, device_tree.c (scand_*): New functions.
1096 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
1098 * filter_filename.c, Makefile.in: Change so that only dependant on
1099 a very limited nr of files. Stops an unnecessary dependency.
1101 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
1103 * core.c (core_map_find_mapping): Use cpu_halt rather than error
1104 to abort an access to an undefined address.

1658 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
1659 make them functions again. Appears 2.6.3 is confused by just a
1662 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
1664 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
1666 * psim.c (psim_create): Not correctly checking that runtime
1667 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
1668 matched the compiled in ones.
1670 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
1671 trace_semantics is now different to trace_idecode, the former
1674 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
1676 * ppc-instructions (mtsrin): Missing instruction
1677 * ppc-instructions (mfsrin): Missing instruction
1678 * ppc-instructions (eieio): Missing instruction
1680 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
1682 * build-psim: New shell script - see internals for usage,
1683 simplifies the process of building custom simulators.
1685 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
1687 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
1688 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
1689 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
1690 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
1691 the instruction or data critical paths.
1693 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
1694 the inclusion of device_tree.c/emul_generic.c.
1696 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
1698 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
1699 system.[hc]. Start of suport for multiple emulations and
1700 emulation state (os_emul object).
1702 * emul_generic.[hc]: Start of code to implement proper system call
1705 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
1707 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
1708 the processor is started. Fixes problem of registers being
1709 undefined when restarting from within gdb.
1711 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
1712 instruction cache (if present). Fixes problem of cpu caching gdb
1713 breakpoint instructions.
1715 FIXME: PSIM sometimes aborts calling error(), it should instead
1716 call sim_error() say which takes care of housekeeping such as
1717 saving the CIA before calling error.
1719 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
1720 used when restarting a simulation because the latter has the
1721 unwanted side effect (well I as a kernel hacker think it is) of
1722 performing an isync when the instruction stream doesn't contain
1725 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
1727 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
1728 monitoring module. Counts both instructions issued and
1731 * NOTE: mon does not contain to count instruction loads as this
1732 information is already available from the mon_issue() hook.
1734 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
1736 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
1737 a common monitor to each of the cpus. Delete
1738 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
1739 replaced by copied code in mon.[hc].
1741 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
1743 * sim_calls.c, main.c, psim.c (psim_create): always create
1744 `WITH_SMP' cpus. The actual number of CPU's active in a
1745 simulation run is taken from the device node: /init/smp (an
1746 integer). WITH_SMP changed to 2 (remember to put it back to 0).
1748 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
1750 * system.c: More system call emulation. If code appears NetBSD
1751 specific, make conditional to being compiled on a NetBSD system
1754 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
1756 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
1757 lf.[ch](new), table.[ch](new): Split into two generators - igen
1758 that outputs the instruction tables and dgen that outputs the spr
1759 tables. Add -f (filter out) flag to igen to filter out certain
1760 instructions (ex 64 bit ones) from the created tables. Include
1761 $(LIBIBERTY_LIB) in link options in case host lacks some libc
1764 * NOTE: igen, since it was originally written for the
1765 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
1767 * Makefile.in, std-config.h, ppc-cache-rules(new),
1768 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
1769 cache-rule and opcode-rule tables from macros found std-config.h.
1770 Delete corresponding macro's from std-config.h.
1772 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
1773 an table of all the instructions. Code to output a type
1774 enumerating all the instructin names.
1776 * igen.c(lf_print_c_semantic): Move call to increment instruction
1777 counter so that it occures _after_ the instruction has been fully
1778 validated, was double counting illegal/invalid instructions. Add
1779 conditional so only compiled in when WITH_PROFILE enabled (enabled
1782 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
1783 itable.h, count individual instruction types not just total,
1784 adjust reporting functions to output this.
1786 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
1787 Had 32./ instead of 31./
1789 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
1790 bitrot - updated to use newer CR register operators.
1792 * ppc-instructions (64bit Floating Convert from Integer
1793 Doubleword): Correct call to Round_Float().
1795 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
1797 * basics.h: #include "sim_callbacks.h" earlier so that its
1798 prototypes are declared in all other header files.
1800 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
1801 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
1804 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
1805 Add size of buffer argument to functions writing a string into a
1806 buffer. Check for buffer overflow.
1808 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
1810 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
1811 of each device. Make parameter names consistent so macros work.
1812 Use macro's in device functions.
1814 * device_tree.c, devices.h, devices.c: include path to device in a
1815 devices node when creating it.
1817 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
1819 * core.c: add tracing of core-device, adjust parameter names in
1820 core functions to be consistent with those in devices*.
1822 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
1824 * debug.h, debug.c (trace_option): New function. Parses the trace
1825 option, updating the trace array.
1827 * debug.h, debug.c (trace_usage): New function. Outputs the list
1828 of all possible trace options.
1830 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
1831 parse trace options specified with the simpler -t flag. Adjust
1834 * FIXME: basic parsing of command line options is still duplicated
1835 by main.c and sim_calls.c
1837 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1839 * Makefile.in (clean): Delete *.i and *.out files.
1841 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
1842 macros for either assignment or return. Fix SWAP_8 to use a
1843 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
1844 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
1845 that hardwired swapping on/off, let optimizer delete dead code.
1847 * main.c (main): Add printf that we caught a signal and print out
1848 the failing address.
1850 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
1852 * Makefile.in: Remove tabs from otherwise empty line.
1853 Confuses many non-GNU versions of "make".

1862 instructions here so it works with caching.
1863 (gen_idecode_c): Move from here.
1865 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1867 * gen.c, ppc-instructions, psim.c: Fix code for generating
1868 cracking instruction cache. Delete the code that cached just the
1869 result from doing an instruction lookup - this ran slower than no
1872 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
1874 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
1876 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
1877 TCL when gdb is linked with the simulator.
1878 * debug.c (ppc_trace): Ditto.
1879 * sim_calls.c (sim_open): Change trace -> ppc_trace.

1887 psim.o depend on all sources.
1889 * cpu.c (cpu_add_commas): New function to format a long with
1891 (cpu_print_info): Use it to print number_of_insns.
1893 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
1895 (ENDIAN_N): If both target and host byte orders are known, don't
1896 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
1898 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
1899 to allow target specific H2T_n/T2H_n macros to be used.
1900 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
1901 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
1902 of the 3 instruction sequence that runs on 386s.
1904 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
1905 specified on the compile line.
1906 (WITH_BSWAP): If not defined, define as 0.
1908 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
1909 default inline support. Pass INLINE_CFLAGS when compiling.
1911 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
1912 INLINE_DEVICES since GCC doesn't like inline functions that
1913 accept variable arguments.
1914 (stack_ioctl_callback): Make function just static because GCC
1915 doesn't like inline functions that accept variable arguments.
1917 * devices.h (STATIC_DEVICES): Define as empty if not defined.
1919 * inline.c: Correct pathnames of included C files to match current
1922 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
1923 non-zero, define STATIC_DEVICES to be static.
1925 * std-config.h (INLINE): If GNU C and optimizing, define this as
1927 (DEFAULT_INLINE): If not defined, define as 0.
1928 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
1929 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
1930 ({SPREG,IDECODE}_INLINE): Ditto.
1932 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
1934 * ppc-instructions: Initial cut of floating point suport added.
1935 Of note include - use of host IEEE floating point instructions,
1936 use of PowerPC manual pseudo code to handle the FPSCR. It is not
1937 currently a pretty sight.
1939 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
1940 merge into core.h, core.c, core_n.h. The type memory_map replaced
1941 with core_map. This removes a level of pointer indirection when
1942 translating an address.
1944 * memory_map.h, memory_map.c, memory_map_n.h: delete.
1946 * Makefile.in et.al (sorry): tweek to use new core, core_map and

1952 most of the other functions in sim_calls.c.
1954 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
1955 Add macros to better cover up `generic' code. Makes it possible
1956 to step through the generic code!
1958 * vm.c, vm_n.h, Makefile.in: ditto
1960 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
1962 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
1963 callback interface so that there is a read/write buffer but no
1964 read/write_word. VEA default memory read/write handler sometimes
1965 couldn't resolve an access and of those some were for a memory
1966 fault and some were because gdb was making a bogus request.
1968 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
1969 eliminate transfer_mode (raw or cooked) parameter from read/write
1972 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
1974 * ppc-instructions (fmul, fmuls): correct instruction format - had
1977 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
1979 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
1980 scand_*): new functions to parse/print fields in device names
1981 while hiding any machine dependency.
1983 * devices.c, psim.c: Change the stack init code so that it is
1984 handled by a device. Arguments passed across using a device ioctl
1987 * devices.h, devices.c: device ioctl callback changed to allow a
1988 variable number of arguments. This gives greater flexability and
1989 greater chance of bugs.
1991 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
1993 * main.c (printf_filtered, error): Missing va_end() to close off
1994 variable argument use.
1996 * Makefile.in (tmp-gencode): comment out hack to get around some
1997 versions of make not handling files being created as side-effects.
1999 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
2000 alternative file name to use in output files for things like #line
2003 Makefile.in (tmp-gencode): Use gen -n so that debug info is
2006 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the

2026 At present, print the number of instructions executed.
2028 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
2031 * psim.c (psim_print_info): New function to iterate over each of
2032 the CPU's calling cpu_print_info.
2034 * psim.h,cpu.h: Add new declarations.
2036 * sim_calls.c (sim_open): Add argument processing to add the same
2037 switches main.c accepts for the standalone processor.
2038 (sim_close): Call psim_print_info if -I.
2040 * main.c (main): Add comment saying to update sim_calls.c when
2041 adding switches. Add -I to call psim_print_info when done.

2063 * main.c (main): Switch to using getopt. Make -p also set
2064 trace_semantics. Make -a turn on all trace flags. Make -C turn
2067 * device_tree.c (create_option_device_node): Assume a program is
2068 OEA if the start address is < 4096, not just == 0.
2070 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>
2072 * Makefile.in (maintainer-clean): New synonym for realclean.

2114 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au>
2116 * core.c (core_add_data): First growth of bss was being put at
2117 wrong address (0) instead of &end.
2119 * core.c (core_add_stack, core_add_data): Was not handling case
2120 where bss/stack is grown across the current end-of-{bss,stack}.
2122 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
2124 * system.c (system_call): Fix SYS_break - was aligning bss to a
2125 page boundary instead of just an 8 byte one; On first call sbrk(0)

2145 and make tracing output line up.
2147 * Makefile.in: Rewrite from Makefile to work with the Cygnus
2148 environment, and support compiling in a different directory than
2149 the sources reside in.
2151 * ppc-endian.h: Rename from endian.h so that it doesn't get
2152 confused with /usr/include/sys/endian.h on Linux. Add Linux
2155 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
2156 Include ppc-endian.h, not endian.h.

2186 Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney@highland.com.au>
2188 * device_tree.c (create_option_device_node): Alignment rules (at
2189 least for the moment) now are for strict alignment only for LE OEA
2190 mode. (Because of compiler problems).
2192 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
2194 Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
2196 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
2199 * system.c (system_call): didn't page align break argument before
2200 determining increment break increment.
2202 * psim/ppc: Re-arange entire directory structure so that
2203 everything lives in the one directory. While a pain for cleaning,
2204 makes building across multiple architectures much simpler.
2206 * devices.c, device_tree.c: Added code that provides a simple
2207 illustration of how an interrupt control device could be
2210 * devices.c: Added code so that the dumb console device can read
2211 (from stdin) as well as write to stdout.
