sim: rename ChangeLog files to ChangeLog-2021

Now that ChangeLog entries are no longer used for sim patches,
this commit renames all relevant sim ChangeLog to ChangeLog-2021,
similar to what we would do in the context of the "Start of New
Year" procedure.

The purpose of this change is to avoid people merging ChangeLog
entries by mistake when applying existing commits that they are
currently working on.

Also throw in a .gitignore entry to keep people from adding new
ChangeLog files anywhere in the sim tree.

+        they are paramaterised with the type of the function.  Gets around
+        the problem of `static' needing to come first with `attribute'

+ 	way around?).
+
+	* vm.c (vm_synchronize_context): Fix wrong test for unsuported
+ 	change in endian-mode.
+
+	* std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE,

+        into the tree.
+
+	* device.c (*add*): Change semantics so the add functions only add
+        when the new device (or property) doesn't already exist.  This

+	(gen_itable_h,itable_c_insn): Ditto.
+	(model support): Move model support around, add support for

+
+Mon Nov 13 23:03:45 1995  Andrew Cagney   <cagneyhighland.com.au>

+	* cpu.c (cpu_get_time_base): Fix calculation of current value of

+
+	* ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
+        m[tf]tb with m[tf]spr.
+
+	* ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
+        lower word.
+
+Mon Nov 13 21:35:37 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* std-config.h (INLINE, STATIC_INLINE): Was being set to static
+        inline..  Only problem being that with ppc-opcode-simple this gave
+        it the chance to inline all the idecode functions with potentially
+        disasterous results on a 16mb PC.  For moment hobble INLINE.
+
+	* configure.in, std-config.h (WITH_SMP): Make that 5 processors by
+        default ...
+
+	* configure.in: Tweek flags passed to gcc for --with-sim-warnings.
+        Firstly make them errors and secondly remove the options gcc-245
+        doesn't reconize.
+
+Mon Nov 13 17:57:24 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* misc.c (zalloc), cpu.c (cpu_init), devices
+ 	(console_io_read_buffer_callback, icu_io_read_buffer_callback,
+ 	vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
+ 	sim_calls.c (zalloc) : replace bzero() with memset().
+
+	* emul_netbsd.c (write_direntries), psim.c (psim_read_register,
+ 	psim_write_register): replace bcopy() with memcpy().
+
+Sun Nov 12 20:55:41 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* configure.in: for --disable-sim-inline (--enable-sim-inline=no),
+        force DEFAULT_INLINE to 0 rather then trusting the std
+        configuration.
+
+Sun Nov 12 20:55:41 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
+        generation of switch entries in tables - treat the same as
+        cracking/semantic functions.
+
+	* igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
+        of a boolean switch statement (field zero or non-zero).
+
+	* ppc-opcode-test-1, ppc-opcode-test-2: New files.  These test the
+        switch/table generation ability of igen.
+
+	* igen.c (idecode_switch_leaf): Fix code output when a switch
+        statement needs to look up a table.
+
+	* igen.c (idecode_declare_if_switch): New function called from
+        gen_idecode_c - need to declare any idecode switch functions
+        before they are used in idecode tables.
+
+	* igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
+        idecode_crack_insn): Add is_inline_function argument to code
+        printing cracker functions which indicates if STATIC_IDECODE or
+        STATIC_INLINE_IDECODE should be used for definition.  For
+        idecode_crack_insn (which implies not duplicating/expanding) don't
+        declare function as inline - we assume that the only time this is
+        code is generated is when things are being tested.  For
+        idecode_crack_leaf, make static (instead of INLINE) if the
+        instructions parent is a table as function will always be called
+        via a table.
+
+	* igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
+        STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
+        called directly, all others are called via a table.
+
+	* igen.c (lf_print_semantic_function_header, semantics_h_leaf,
+        semantics_h_insn, semantics_h_function,
+        lf_print_c_semantic_function, semantics_c_function): Add
+        is_inline_function argument to lf_print_semantic_function_header
+        to indicate if an inline or static function declaration/definition
+        should be output.  Depending on situtation call accordingly:
+        functions (not instruction semantic routines) are always inline;
+        Semantic routines are made inline when there is no icache (cache
+        will contain the function address) and are duplicating (see above)
+        and the parent of the instruction is a switch statement.
+
+	* igen.c (opcode_field_new): Delete.  Code changed to use ZALLOC
+        and moved to insn_table_find_opcode_field.
+
+	* table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
+
+	* igen.c (model_c_insn): Suggestion - document the name of the
+        instruction on each line of the instruction model table.
+
+Fri Nov 10 00:44:38 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* emul_netbsd.c (do_ioctl): Cleanup compilation.
+
+	* sim_callbacks.h (__attribute__): Only define if not defined (was
+        already defined on NetBSD host).
+
+Wed Nov  8 21:49:52 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
+        macro, indicates if the PowerPC's horrible XOR endian mode should
+        be suported.  Add to configure and make.
+
+	* vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
+        (vm_instruction_map_read): If XOR endian, xor the address
+	with a value from an xor table (indexed by size of access).
+
+	* vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
+        set up xor table to xor if there is a conflict between the
+        CURRENT_TARGET_ENDIAN and the endian indicated in the MSR.  Move
+        check of suported change of endian mode from cpu.c to vm.c.
+
+	* vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
+        Hopefully added correct hack to handle XOR endian mode.
+
+	FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
+        little endian mode, the model accepts miss aligned transfers.
+
+	FIXME: Need to create an `init' device that, during
+        initializatioin for XOR mode, it mushes (XOR address) all the dma
+        data before passing it on to the core for storage. Just like the
+        real thing really.
+
+Wed Nov  8 21:49:52 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* devices.c (halt_io_write_buffer_callback): Use value written to
+        halt device to determine exit status.  Thus allowing
+        success/failure of OEA tests.
+
+Wed Nov  8 00:10:38 1995  Andrew Cagney   <cagneyhighland.com.au>

+
+	* device_tree.h, device_tree.c (scand_*): New functions.
+
+Tue Nov  7 23:36:31 1995  Andrew Cagney   <cagneyhighland.com.au>
+
+	* filter_filename.c, Makefile.in: Change so that only dependant on
+        a very limited nr of files.  Stops an unnecessary dependency.
+
+Tue Nov  7 15:44:33 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* core.c (core_map_find_mapping): Use cpu_halt rather than error
+ 	to abort an access to an undefined address.

+
+	* sim-endian.h (SWAP_N), sim-endian.c (_SWAP_1): Rename existing
+        SWAP_<N> to _SWAP_<N> so that sim-endian.h can contain SWAP_N
+        macro's as required.
+
+	* sim-endian.c, sim-endian-n.h (new file): Move endian code into a
+        debugable header file.
+
+	* ppc-instructions (Byte-Reverse): Enable byte reverse
+        instructions using SWAP_N macros.
+
+Mon Nov  6 10:39:28 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+

+
+	* Makefile.in: Uncomment built file dependencies.
+
+	* configure.in: Rewrite --enable-sim switch handling to use the
+	autoconf builtins so it works correctly if the configure or
+	Makefile.in files are modified and make decides to rebuild
+	Makefile.  Also document all of the --enable-sim switches
+	supported.  Check whether getrusage and sys/resource.h are
+	supported.
+	* config.in: Regenerate.
+	* configure: Regenerate.
+	* Makefile.in: Add support for all of the variables set with
+	--enable-sim switches.

+	well.
+
+	* cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H,
+	HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in

+
+
+	* main.c (main): Call psim_print_info with verbose == 2.
+
+	* mon.c (mon_print_info): Align the cpu number and number of
+	instructions fields.  Do not print an instruction category if the

+
+Wed Nov  1 23:46:59 1995  Andrew Cagney   <cagney@highland.com.au>
+
+	* std-config (INLINE_DEVICE_TREE): Don't inline either of
+        device_tree.c or devices.c.  There is no significant gain.
+
+	* configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
+ 	IGEN_ICACHE macro.
+
+Wed Nov  1 23:46:59 1995  Andrew Cagney   <cagney@highland.com.au>
+
+	* igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
+        functions to convert between target and igen internal bit numbers.
+        Make IO go through these functions. Add -b (bit size) and -h (high
+        bit nr) options to igen.  Typical usage would be: ./igen -b 16 -h
+        15 for a 16 bit instruction format with the msb given a number 15.
+
+Wed Nov  1 22:17:32 1995  Andrew Cagney   <cagney@highland.com.au>
+
+	* dgen.c (main): Was outputting optarg even when it was NULL.
+
+Tue Oct 31 23:48:33 1995  Andrew Cagney   <cagney@highland.com.au>
+

+Tue Oct 31 21:44:01 1995  Andrew Cagney   <cagney@highland.com.au>
+
+        * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does
+        not include things such as the time base and events.
+
+	* interrupt.c, sim_calls.c, cpu.h, vm.c, configure.in: Add UEA to
+ 	all environment switches for above.
+
+	* psim.c (psim_create): ditto - new device tree node name is
+        /options/environment-architecture with values user, virtual and
+        operating.
+
+Tue Oct 31 21:31:32 1995  Andrew Cagney   <cagney@highland.com.au>
+
+	* ppc-opcode-stupid: Third example of use of opcode table - this
+        one expands all mtspr/mfspr and branch instructions.  Appears to
+        give about a 10% gain in performance if everything enabled.  Also
+        takes about 150mb of swap to build.
+
+Wed Nov  1 10:49:48 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* emul_netbsd.c (do_exit): Print arguments and close parenthesis

+	invalid instructions.
+
+	* configure.in: Add support for more --enable-sim-* switches.
+	Use config.make and config.hdr to write to Makefile and config.h

+	variables.
+	* configure: Regenerate from configure.in.
+	* Makefile.in: Add various Make variables that the various
+	switches alter.
+
+	* std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
+	and optimizing by default.
+
+Fri Oct 27 19:26:27 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* bits.h (ROTL32, ROTL64): Were functions, made them macros, now
+ 	make them functions again.  Appears 2.6.3 is confused by just a
+ 	macro.
+
+Thu Oct 26 18:31:58 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* ppc-endian.c (SWAP_8): Fix 8 byte swap!
+
+	* psim.c (psim_create): Not correctly checking that runtime
+ 	configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
+ 	matched the compiled in ones.
+
+	* debug.h (ITRACE), igen.c: Tidy up more tracing flags -
+ 	trace_semantics is now different to trace_idecode, the former
+ 	checks the cache.
+
+Tue Oct 24 21:54:13 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* ppc-instructions (mtsrin): Missing instruction
+	* ppc-instructions (mfsrin): Missing instruction
+	* ppc-instructions (eieio): Missing instruction
+
+Tue Oct 24 20:55:29 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* build-psim: New shell script - see internals for usage,
+ 	simplifies the process of building custom simulators.
+
+Mon Oct 23 23:48:59 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
+        INLINE macros.  Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
+        Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
+        DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
+        the instruction or data critical paths.
+
+	* FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
+ 	the inclusion of device_tree.c/emul_generic.c.
+
+Mon Oct 23 00:31:50 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
+        system.[hc].  Start of suport for multiple emulations and
+        emulation state (os_emul object).
+
+	* emul_generic.[hc]: Start of code to implement proper system call
+	tracing (from spy).
+
+Sun Oct 22 21:33:51 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* cpu.h, cpu.c (cpu_init): New function, zero the registers before
+        the processor is started. Fixes problem of registers being
+        undefined when restarting from within gdb.
+
+	* cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
+        instruction cache (if present).  Fixes problem of cpu caching gdb
+        breakpoint instructions.
+
+	FIXME: PSIM sometimes aborts calling error(), it should instead
+ 	call sim_error() say which takes care of housekeeping such as
+ 	saving the CIA before calling error.
+
+	* NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
+ 	used when restarting a simulation because the latter has the
+ 	unwanted side effect (well I as a kernel hacker think it is) of
+ 	performing an isync when the instruction stream doesn't contain
+ 	one.
+
+Sun Oct 22 19:27:48 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
+        monitoring module. Counts both instructions issued and
+        load/stores.
+
+	* NOTE: mon does not contain to count instruction loads as this
+ 	information is already available from the mon_issue() hook.
+
+	* igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
+
+	* psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
+        a common monitor to each of the cpus. Delete
+        cpu_increment_number_of_insns() and cpu_get_number_of_insns()
+        replaced by copied code in mon.[hc].
+
+Sun Oct 22 18:42:45 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* sim_calls.c, main.c, psim.c (psim_create): always create
+        `WITH_SMP' cpus.  The actual number of CPU's active in a
+        simulation run is taken from the device node: /init/smp (an
+        integer). WITH_SMP changed to 2 (remember to put it back to 0).
+
+Fri Oct 20 17:26:54 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* system.c: More system call emulation.  If code appears NetBSD
+ 	specific, make conditional to being compiled on a NetBSD system
+ 	(sigh).
+
+Wed Oct 18 23:02:20 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
+ 	lf.[ch](new), table.[ch](new): Split into two generators - igen
+ 	that outputs the instruction tables and dgen that outputs the spr
+ 	tables.  Add -f (filter out) flag to igen to filter out certain
+ 	instructions (ex 64 bit ones) from the created tables.  Include
+ 	$(LIBIBERTY_LIB) in link options in case host lacks some libc
+ 	functions.
+
+	* NOTE: igen, since it was originally written for the
+ 	PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
+
+	* Makefile.in, std-config.h, ppc-cache-rules(new),
+ 	ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
+ 	cache-rule and opcode-rule tables from macros found std-config.h.
+ 	Delete corresponding macro's from std-config.h.
+
+	* igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
+ 	an table of all the instructions.  Code to output a type
+ 	enumerating all the instructin names.
+
+	* igen.c(lf_print_c_semantic): Move call to increment instruction
+ 	counter so that it occures _after_ the instruction has been fully
+ 	validated, was double counting illegal/invalid instructions.  Add
+ 	conditional so only compiled in when WITH_PROFILE enabled (enabled
+ 	by default).
+
+	* igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
+ 	itable.h, count individual instruction types not just total,
+ 	adjust reporting functions to output this.
+
+	* ppc-instructions (64 bit Load Doubleword with Update Indexed):
+ 	Had 32./ instead of 31./
+
+	* ppc-instructions (64 bit Store Double Word Conditional Indexed):
+ 	bitrot - updated to use newer CR register operators.
+
+	* ppc-instructions (64bit Floating Convert from Integer
+ 	Doubleword): Correct call to Round_Float().
+
+Mon Oct 16 00:31:20 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* basics.h: #include "sim_callbacks.h" earlier so that its
+ 	prototypes are declared in all other header files.
+
+	* bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
+ 	doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
+ 	bits.h.
+
+	* cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
+ 	Add size of buffer argument to functions writing a string into a
+ 	buffer.  Check for buffer overflow.
+
+Sun Oct 15 22:16:11 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* devices.h, devices.c, debug.h, debug.c: add macro's for tracing
+        of each device.  Make parameter names consistent so macros work.
+        Use macro's in device functions.
+
+	* device_tree.c, devices.h, devices.c: include path to device in a
+        devices node when creating it.
+
+	* device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
+
+	* core.c: add tracing of core-device, adjust parameter names in
+ 	core functions to be consistent with those in devices*.
+
+Sun Oct 15 20:33:20 1995  Andrew Cagney  <cagney@highland.com.au>
+
+        * debug.h, debug.c (trace_option): New function. Parses the trace
+        option, updating the trace array.
+
+	* debug.h, debug.c (trace_usage): New function. Outputs the list
+        of all possible trace options.
+
+	* sim_calls.c (sim_open), main.c (main): Use new trace_option() to
+ 	parse trace options specified with the simpler -t flag.  Adjust
+ 	usage.
+
+	* FIXME: basic parsing of command line options is still duplicated
+ 	by main.c and sim_calls.c
+
+Thu Oct 26 10:42:28 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* Makefile.in (clean): Delete *.i and *.out files.
+
+	* ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
+	macros for either assignment or return.  Fix SWAP_8 to use a
+	union, and two SWAP_4's.  Delete SWAP_N, since nobody uses it now.
+	(ENDIAN_N): Add SET argument to SWAP_n calls.  Delete macro defs
+	that hardwired swapping on/off, let optimizer delete dead code.
+
+	* main.c (main): Add printf that we caught a signal and print out
+	the failing address.
+
+Thu Oct 19 21:43:39 1995  Fred Fish  <fnf@fishfood.amigalib.com>
+
+	* Makefile.in:  Remove tabs from otherwise empty line.
+	Confuses many non-GNU versions of "make".

+Wed Oct 18 08:51:25 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* Makefile.in (clean): Delete files produced by gen.
+
+Mon Oct 16 17:34:24 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* gen.c (lf_print_c_semantic_function): Move counting # of
+	instructions here so it works with caching.
+	(gen_idecode_c): Move from here.
+
+Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* gen.c, ppc-instructions, psim.c: Fix code for generating
+	cracking instruction cache.  Delete the code that cached just the
+	result from doing an instruction lookup - this ran slower than no
+	cache at all.
+
+Fri Oct 13 09:58:43 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* Makefile.in (gen.o): Include $(INLINE_CFLAGS).
+
+	* debug.h (ppc_trace): Rename from trace, to avoid a conflict with
+	TCL when gdb is linked with the simulator.
+	* debug.c (ppc_trace): Ditto.
+	* sim_calls.c (sim_open): Change trace -> ppc_trace.
+	* main.c (main): Ditto.

+Thu Oct 12 11:35:53 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* Makefile.in (psim.o): Now that inlines are turned on, make
+	psim.o depend on all sources.
+
+	* cpu.c (cpu_add_commas): New function to format a long with
+	commas.
+	(cpu_print_info): Use it to print number_of_insns.
+
+	* ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
+	2, 4, and 8 bytes.
+	(ENDIAN_N): If both target and host byte orders are known, don't
+	bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
+
+	* ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
+	to allow target specific H2T_n/T2H_n macros to be used.
+	(htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
+	non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
+	of the 3 instruction sequence that runs on 386s.
+
+	* std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
+	specified on the compile line.
+	(WITH_BSWAP): If not defined, define as 0.
+
+	* Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
+	default inline support.  Pass INLINE_CFLAGS when compiling.
+
+	* devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
+	INLINE_DEVICES since GCC doesn't like inline functions that
+	accept variable arguments.
+	(stack_ioctl_callback): Make function just static because GCC
+	doesn't like inline functions that accept variable arguments.
+
+	* devices.h (STATIC_DEVICES): Define as empty if not defined.
+
+	* inline.c: Correct pathnames of included C files to match current
+	implementation.
+
+	* inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
+	non-zero, define STATIC_DEVICES to be static.
+
+	* std-config.h (INLINE): If GNU C and optimizing, define this as
+	__inline__.
+	(DEFAULT_INLINE): If not defined, define as 0.
+	(ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
+	({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
+	({SPREG,IDECODE}_INLINE): Ditto.
+
+Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@highland.com.au>
+
+        * ppc-instructions: Initial cut of floating point suport added.
+  	Of note include - use of host IEEE floating point instructions,
+ 	use of PowerPC manual pseudo code to handle the FPSCR.  It is not
+ 	currently a pretty sight.
+
+	* memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
+ 	merge into core.h, core.c, core_n.h. The type memory_map replaced
+ 	with core_map.  This removes a level of pointer indirection when
+ 	translating an address.
+
+	* memory_map.h, memory_map.c, memory_map_n.h: delete.
+
+	* Makefile.in et.al (sorry): tweek to use new core, core_map and
+ 	core.h.
+
+Wed Oct 11 12:10:26 1995  Andrew Cagney  <cagney@highland.com.au>
+
+	* sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to

+
+Tue Oct 10 15:42:59 1995  Andrew Cagney  <cagney@highland.com.au>
+

-
-Mon Nov 13 21:35:37 1995  Andrew Cagney   <cagneyhighland.com.au>
-
-	* std-config.h (INLINE, STATIC_INLINE): Was being set to static
-        inline..  Only problem being that with ppc-opcode-simple this gave
-        it the chance to inline all the idecode functions with potentially
-        disasterous results on a 16mb PC.  For moment hobble INLINE.
-
-	* configure.in, std-config.h (WITH_SMP): Make that 5 processors by

-	
-Sun Nov 12 20:55:41 1995  Andrew Cagney   <cagneyhighland.com.au>
-
-	* configure.in: for --disable-sim-inline (--enable-sim-inline=no),
-        force DEFAULT_INLINE to 0 rather then trusting the std
-        configuration.
-
-Sun Nov 12 20:55:41 1995  Andrew Cagney   <cagneyhighland.com.au>
-
-	* igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
-        generation of switch entries in tables - treat the same as
-        cracking/semantic functions.
-
-	* igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
-        of a boolean switch statement (field zero or non-zero).
-
-	* ppc-opcode-test-1, ppc-opcode-test-2: New files.  These test the
-        switch/table generation ability of igen.
-
-	* igen.c (idecode_switch_leaf): Fix code output when a switch
-        statement needs to look up a table.
-
-	* igen.c (idecode_declare_if_switch): New function called from
-        gen_idecode_c - need to declare any idecode switch functions
-        before they are used in idecode tables.
-
-	* igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
-        idecode_crack_insn): Add is_inline_function argument to code
-        printing cracker functions which indicates if STATIC_IDECODE or
-        STATIC_INLINE_IDECODE should be used for definition.  For
-        idecode_crack_insn (which implies not duplicating/expanding) don't
-        declare function as inline - we assume that the only time this is
-        code is generated is when things are being tested.  For
-        idecode_crack_leaf, make static (instead of INLINE) if the
-        instructions parent is a table as function will always be called
-        via a table.
-
-	* igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
-        STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
-        called directly, all others are called via a table.
-
-	* igen.c (lf_print_semantic_function_header, semantics_h_leaf,
-        semantics_h_insn, semantics_h_function,
-        lf_print_c_semantic_function, semantics_c_function): Add
-        is_inline_function argument to lf_print_semantic_function_header
-        to indicate if an inline or static function declaration/definition
-        should be output.  Depending on situtation call accordingly:
-        functions (not instruction semantic routines) are always inline;
-        Semantic routines are made inline when there is no icache (cache
-        will contain the function address) and are duplicating (see above)
-        and the parent of the instruction is a switch statement.
-
-	* igen.c (opcode_field_new): Delete.  Code changed to use ZALLOC
-        and moved to insn_table_find_opcode_field.
-
-	* table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
-
-	* igen.c (model_c_insn): Suggestion - document the name of the
-        instruction on each line of the instruction model table.
-
-Fri Nov 10 00:44:38 1995  Andrew Cagney   <cagneyhighland.com.au>
-
-	* emul_netbsd.c (do_ioctl): Cleanup compilation.

-
-	* std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
-        macro, indicates if the PowerPC's horrible XOR endian mode should
-        be suported.  Add to configure and make.
-
-	* vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
-        (vm_instruction_map_read): If XOR endian, xor the address
-	with a value from an xor table (indexed by size of access).
-
-	* vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
-        set up xor table to xor if there is a conflict between the
-        CURRENT_TARGET_ENDIAN and the endian indicated in the MSR.  Move
-        check of suported change of endian mode from cpu.c to vm.c.
-
-	* vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
-        Hopefully added correct hack to handle XOR endian mode.
-
-	FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
-        little endian mode, the model accepts miss aligned transfers.
-
-	FIXME: Need to create an `init' device that, during
-        initializatioin for XOR mode, it mushes (XOR address) all the dma
-        data before passing it on to the core for storage. Just like the
-        real thing really.
-
-Wed Nov  8 21:49:52 1995  Andrew Cagney   <cagneyhighland.com.au>
-
-	* devices.c (halt_io_write_buffer_callback): Use value written to
-        halt device to determine exit status.  Thus allowing
-        success/failure of OEA tests.

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

-
-Tue Oct 31 21:31:32 1995  Andrew Cagney   <cagney@highland.com.au>
-
-	* ppc-opcode-stupid: Third example of use of opcode table - this
-        one expands all mtspr/mfspr and branch instructions.  Appears to
-        give about a 10% gain in performance if everything enabled.  Also

-Fri Oct 27 19:26:27 1995  Andrew Cagney  <cagney@highland.com.au>
-
-	* bits.h (ROTL32, ROTL64): Were functions, made them macros, now
- 	make them functions again.  Appears 2.6.3 is confused by just a
- 	macro.
-
-Thu Oct 26 18:31:58 1995  Andrew Cagney  <cagney@highland.com.au>
-
-	* ppc-endian.c (SWAP_8): Fix 8 byte swap!

-
-Mon Oct 23 23:48:59 1995  Andrew Cagney  <cagney@highland.com.au>
-
-	* std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
-        INLINE macros.  Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
-        Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
-        DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
-        the instruction or data critical paths.
-  	
-	* FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
- 	the inclusion of device_tree.c/emul_generic.c.

-        undefined when restarting from within gdb.
-
-	* cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
-        instruction cache (if present).  Fixes problem of cpu caching gdb
-        breakpoint instructions.
-
-	FIXME: PSIM sometimes aborts calling error(), it should instead
- 	call sim_error() say which takes care of housekeeping such as
- 	saving the CIA before calling error.
-	
-	* NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
- 	used when restarting a simulation because the latter has the
- 	unwanted side effect (well I as a kernel hacker think it is) of
- 	performing an isync when the instruction stream doesn't contain
- 	one.
-
-Sun Oct 22 19:27:48 1995  Andrew Cagney  <cagney@highland.com.au>
-
-	* mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance

-
-	* sim_calls.c, main.c, psim.c (psim_create): always create
-        `WITH_SMP' cpus.  The actual number of CPU's active in a
-        simulation run is taken from the device node: /init/smp (an
-        integer). WITH_SMP changed to 2 (remember to put it back to 0).
-
-Fri Oct 20 17:26:54 1995  Andrew Cagney  <cagney@highland.com.au>
-
-	* system.c: More system call emulation.  If code appears NetBSD

- 	$(LIBIBERTY_LIB) in link options in case host lacks some libc
- 	functions.
-
-	* NOTE: igen, since it was originally written for the
- 	PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
-	
-	* Makefile.in, std-config.h, ppc-cache-rules(new),
- 	ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
- 	cache-rule and opcode-rule tables from macros found std-config.h.

- 	an table of all the instructions.  Code to output a type
- 	enumerating all the instructin names.
-
-	* igen.c(lf_print_c_semantic): Move call to increment instruction
- 	counter so that it occures _after_ the instruction has been fully
- 	validated, was double counting illegal/invalid instructions.  Add
- 	conditional so only compiled in when WITH_PROFILE enabled (enabled
- 	by default).
-	
-	* igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
- 	itable.h, count individual instruction types not just total,

-
-	* ppc-instructions (64bit Floating Convert from Integer
- 	Doubleword): Correct call to Round_Float().

-
-	* bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
- 	doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into

-
-	* cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
- 	Add size of buffer argument to functions writing a string into a
- 	buffer.  Check for buffer overflow.

-
-	* sim_calls.c (sim_open), main.c (main): Use new trace_option() to

-
-	* Makefile.in (clean): Delete *.i and *.out files.

-
-	* gen.c, ppc-instructions, psim.c: Fix code for generating
-	cracking instruction cache.  Delete the code that cached just the
-	result from doing an instruction lookup - this ran slower than no
-	cache at all.
-
-Fri Oct 13 09:58:43 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
-
-	* Makefile.in (gen.o): Include $(INLINE_CFLAGS).

-	(ENDIAN_N): If both target and host byte orders are known, don't
-	bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
-
-	* ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
-	to allow target specific H2T_n/T2H_n macros to be used.
-	(htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is

-Wed Oct 11 17:13:15 1995  Andrew Cagney  <cagney@highland.com.au>
-
-        * ppc-instructions: Initial cut of floating point suport added.
-  	Of note include - use of host IEEE floating point instructions,
- 	use of PowerPC manual pseudo code to handle the FPSCR.  It is not
- 	currently a pretty sight.
-	
-	* memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
- 	merge into core.h, core.c, core_n.h. The type memory_map replaced
- 	with core_map.  This removes a level of pointer indirection when
- 	translating an address.
-
-	* memory_map.h, memory_map.c, memory_map_n.h: delete.
-
-	* Makefile.in et.al (sorry): tweek to use new core, core_map and

-
-	* basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
- 	Add macros to better cover up `generic' code.  Makes it possible
- 	to step through the generic code!
-
-	* vm.c, vm_n.h, Makefile.in: ditto
-	
-Tue Oct 10 15:42:59 1995  Andrew Cagney  <cagney@highland.com.au>
-
-	* devices.h, devices.c, memory_map.h, memory_map.c: Changed
- 	callback interface so that there is a read/write buffer but no
- 	read/write_word.  VEA default memory read/write handler sometimes
- 	couldn't resolve an access and of those some were for a memory
- 	fault and some were because gdb was making a bogus request.
-
-	* devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
- 	eliminate transfer_mode (raw or cooked) parameter from read/write
- 	buffer.
-

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