+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

+
+Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * misc.c (zalloc), cpu.c (cpu_init), devices

+
+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>
+
+ * ppc-instructions (icbi): If icache present flush it.
+
+Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
+
+ * devices.c (htab_init_callback): Add code to create htab/pte.
+
+ * devices.c (dma_file, file_init_callback, htab_init_callback):
+ New function - Dma the named file into memory at the specified
+ address. Use.
+
+ * 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.

+
+ * 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

+ 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

+
+ * configure.in: Add support for --enable-sim-opcode=stupid.

+
+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 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

+
+Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
+
+ * emul_netbsd.c (do_exit): Print arguments and close parenthesis

+ 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!

+ 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

+
+Tue Oct 24 20:55:29 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

+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

+ 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.

+
+ * 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

+ * 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__.

+ ({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

+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
+ most of the other functions in sim_calls.c.

+
+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.
+
+Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * ppc-instructions (fmul, fmuls): correct instruction format - had

+
+Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
+ 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.

- * 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.

- 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.

- 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.

-
-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.

-
- * ppc-endian.c (SWAP_8): Fix 8 byte swap!

-
- * ppc-instructions (mtsrin): Missing instruction

- the instruction or data critical paths.
-
- * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from

-
-Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>

- 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

-
- * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
- a common monitor to each of the cpus. Delete

-
-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

- functions.
-
- * NOTE: igen, since it was originally written for the
- PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.

- 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.

- 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.

- 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

- * ppc-endian.c: Rename to be consistant with ppc-endian.h.
- Include ppc-endian.h, not endian.h.
-
- * basics.h (sysdep.h): Include sysdep.h that configure makes.
- Include ppc-endian.h, not endian.h.
-
- * std-config.h: Rename from ppc-config. Put #ifndefs around most
- configuration macros, so they can be overridden via CFLAGS. By
- default, turn off tracing.
-
- * configure.in: Clone from other simulator targets.
- * configure: Generate via autoconf from configure.in.
-
-Sat Aug 19 09:05:32 1995 Andrew Cagney <cagney@highland.com.au>
-
- * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
-
- * interrupts.c (data_storage_interrupt): allow stack to grow by
- upto one MB per increment.
-
- * ppc-instructions: divw was computing rA / rA not rA / rB
-
- * main.c (main): really stupid. Wasn't exiting with correct status
-
-Fri Aug 18 00:38:01 1995 Andrew Cagney <cagney@highland.com.au>
-
- * system.c (system_call): add system calls kill(2) and getpid(2).
-
- * main.c (main): Check/return exit status when simulation
- finishes.
-
-Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney@highland.com.au>
-
- * device_tree.c (create_option_device_node): Alignment rules (at
- least for the moment) now are for strict alignment only for LE OEA
- mode. (Because of compiler problems).
-
- * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
-
-Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
-
- * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
- forgot to return.
-
- * system.c (system_call): didn't page align break argument before
- determining increment break increment.
-
- * psim/ppc: Re-arange entire directory structure so that
- everything lives in the one directory. While a pain for cleaning,
- makes building across multiple architectures much simpler.
-
- * devices.c, device_tree.c: Added code that provides a simple
- illustration of how an interrupt control device could be
- implemented.
-
- * devices.c: Added code so that the dumb console device can read
- (from stdin) as well as write to stdout.
