1504 time for.
1505 * emul_generic.c (emul_add_tree_options): Only require strict
1506 alignment if it was explicitly requested at configuration time.
1507 Don't make it the default for little-endian machines.
1508 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1509 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1510 THRM2, THRM3): Plop in the MPC750 SPR registers.
1511 (DABR): This is weird. This was HID5, but the PPC spec says this
1512 should be DABR; why did some random processor use it for something
1513 else? The HID5 entry dates back to the original checkin of the
1514 simulator code in 1995, so remove it.
1515 * sim_calls.c (register_names): Delete this; since the user can
1516 now change GDB's list of register names dynamically, we can't
1517 pretend there's a static mapping here.
1518 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1519 function to get the register name. That ought to be accurate.
1520 However, we're changing a compile-time dependency (using the
1521 REGISTER_NAMES macro) into a link- and run-time dependency
1522 (calling REGISTER_NAME, which happens to be a function call on the
1523 PPC).
1525 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1527 * igen.c(gen_semantics_[ch]): setup/use of new option
1528 (-o mpc860c0[=n]).

1530 ppc-instructions(the four branch insn groups): detect problematic br's.
1531 psim.c(is_num - added, psim_options): Parse and init new option.
1532 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1534 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1536 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1547 poll the external environment.
1549 1998-11-19 Michael Meissner <meissner@cygnus.com>
1551 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1552 fractional type, so that quiet NaN's aren't treated like
1553 Infinities.
1555 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1557 * table.c (table_open): For cygwin hosts, we need to use the
1558 return value from the read routine as the number of bytes to
1559 process. This apparently is due to text-mode vs binary-mode. If
1560 the mounts are done text-mode, then the size returnedby fstat()
1561 may be different than the number of bytes "read" in text mode.
1563 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1565 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1582 * configure: Regenerate.
1583 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1584 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1586 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1588 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1589 but there was no such target, only plain psim. So I changed the
1590 run target to depend on psim.
1592 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1594 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1595 now defined in ../common/aclocal.m4, and the double definition causes
1596 problems with AC_SUBST of EXEEXT.

1679 (sim_io_flush_stdoutput): Replace gdb_flush with callback ->
1680 flush_stdout.
1682 Fri Sep 26 09:50:29 1997 Andrew Cagney <cagney@b1.cygnus.com>

1928 Augment each extracted field with a comment citing the codes
1929 origin. Should simplify tracking down incorrect cache
1930 extractions.

1956 entry code so that it involves a mask + test instead of shift +
1957 shift + mask + test.
1959 * gen-idecode.c: Correct generated igen body so that it no drops
1960 or doubles clock interrupts.

1997 * When performance monitoring is disabled, it is still possible to
1998 determine the simulation speed by looking at the number of elapsed
1999 ticks recorded by the event queue.
2001 * psim.c (psim_write_register, psim_read_register): Force the cpu
2002 to zero when it is either of `-1' or `nr_cpus'. In both cases the
2003 next cpu would be zero any way.
2005 * mon.c (mon_print_info): If possible, print the system cycle
2006 performance. This is an indication of the number of instructions
2007 per second.
2009 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2011 * The code to allow an event queue to be updated during a signal
2012 was missing. For main.c, a cntrl-c simulation termination wasn't
2013 handled cleanly.
2015 * The simulation would not correctly restart if an event requested
2016 that the simulation be halted.
2018 * psim.c (psim_options): Add hack to -i option to optionally
2019 include a level vis -i2.
2020 (psim_usage): Document.
2022 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
2023 cntrl-c occures schedule an event to halt the simulation.
2024 (main): Catch CNTRL-C signals with the function cntrl_c.
2026 * events.c (event_queue_process): Mask interrupts while
2027 manipulating the async event queue.

2032 the processing state when processing has started. Adjust code
2033 so that it is tolerant of halts.
2034 (event_queue_init): Start the event queue out with processing
2035 false.
2036 (event_queue_tick): Check that processing isn't still being
2037 performed.
2039 * gen-idecode.c (print_run_until_stop_body): Call
2040 event_queue_process_events to clear possibly pending events before
2041 starting a simulation run. Re-arange main loop so that simulator
2042 is correctly restarted when an event halts the simulation.
2044 * psim.c (psim_halt): Handle an event halting the simulation.
2045 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
2046 reworked idecode.
2048 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2050 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
2051 RA. Based on instruction frequency stats, expand additional
2052 instructions.
2053 * ppc-instructions: Change all `RA == 0' to RA_is_0.
2055 * ppc-opcode-stupid: Move all but the basic table in -complex into
2056 here. Update to new format.
2058 * Makefile.in (tmp-defines): New target. Force defines.h to always
2059 be built. Hence get ppc-opcode-goto to build.
2061 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2063 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
2064 Implement.
2066 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2068 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
2069 to be initialized independant of the rest of the simulation
2070 initalization. Otherwize a trace option explictly set from gdb
2071 could be overridden by hw_trace.
2073 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
2075 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
2076 debug.c. It could be much simpler.
2078 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2080 * Some devices support removable media. Add hooks to the disk

2092 image property list.
2093 (hw_disk_init_address): Change the file property so that it is a
2094 string array - use the first entry for the initial file image.

2106 * psim.c (psim_command): New function, parse more complex psim
2107 commands such as "change-media" and "trace".
2108 * sim_calls.c (sim_do_command): Use.
2110 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2112 * For expressions like (RA == 0) that are entered in to the cache
2113 as RA_is_0. If possible generate the result of the expression so
2114 that the compiler gets a better chance of eliminating dead
2115 branches.
2117 * gen-icache.c (print_icache_extraction): For a cache entry of
2118 the form <name>_is_<const> where it is a boolean field, generate
2119 the result of the expression instead of the expression its self.

2121 then generating corresponding definitions.
2123 * gen-icache.c (print_icache_struct): If there is no cache, do not
2124 output expressions in idecode.h file.
2126 * gen-icache.c (print_icache_body): Output them here.
2128 * ppc-opcode-complex: Clarify constant values for SPR==LR register
2129 expansion.
2131 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
2133 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
2135 * The code that put values in and extracted values from the cache
2136 was too compilicated. The cache table did not allow values to be
2137 computed from cache entries. #defines could only be used when a
2138 cache was present, remove the restriction.
2140 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
2141 scratch variable is defined when a cache entry is beinf
2142 filled. Change the definition of a COMPUTE variable to be defined
2143 when the cache entry is being used.
2144 * gen-icache.c: Update.
2146 * ld-cache.h, ld-cache.c: Change field names so that their meaning
2147 is more obvious. old_name->field_name, new_name->derived_name.
2148 * gen-icache.c: Update
2150 * gen-icache.h, gen-icache.c (print_icache_body): Make the three

2153 * gen-icache.c (print_icache_extraction): Ditto.
2155 * gen-semantics.c (print_c_semantic): Update use.
2156 * gen-idecode.c (print_jump_insn): Update use.
2157 * gen-icache.c (print_icache_function): Update use.
2159 * igen.c (main): Change 'R' option so that it does not force the
2160 cache.
2162 * configure.in (enable-sim-icache): Clarify description. Make
2163 #define one of the defaults regardless of the cache. Probably
2164 should revamp and add a separate option.

2178 * The cap object was retaining a reference to the instance of a
2179 device after it was deleted. Instead add and remove cap's from the
2180 cap db as they are created and deleted. This ensuring that a
2181 capibility is only used during the lifetime of the corresponding
2182 object.
2184 * cap.h, cap.c: Correct cap type - was signed32 should be
2185 signed_cell.
2187 * cap.c (cap_add, cap_remove): New methods for cap object that
2188 allow the explicit addition and removal of internal objects that
2189 the cap knows about.
2191 * cap.c (cap_init): Rewrite. Verify that the only objects
2192 remaining in the cap data base are those that were entered first.
2193 Thse objects will be the permenant ones.
2194 * device.c (device_init_address): Remember to initialize the cap
2195 database.
2197 * device.c (device_create_instance_from): Explicitly add device
2198 instances to the cap database. Simplify create code.

2243 (chirm_emul_release): Ditto.
2245 * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files

2247 not made inline.
2249 * hw_init.c (update_for_binary_section): Fix failure to allocate

3519 * configure.in (--enable-sim-hardware, --enable-sim-packages): New
3520 configuration options. Let the user specify the packages or
3521 hardware devices that are to be included in the build. Makes it
3522 possible for user packages to be specified.
3524 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
3525 hardware instead of checking it using ls. configure.in should
3526 have taken care of any problems.
3527 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
3529 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
3531 * psim.c (psim_options): Enter the argument to the memory size

3571 * : Have the generated idecode.c include inline.c (instead of psim.c).
3573 * std-config.h: Change psim.c so that it isn't inlined (as this is
3574 no longer needed).
3576 * psim.c (run_until_stop): Delete the old run_until_stop function
3577 instead calling the idecode_run and idecode_run_until_stop
3578 functions that gen-idecode.c is now creating.

3605 corresponding call to ITRACE so that it still matches.
3607 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
3608 of ITRACE. The CPP line directives would have previously set the
3609 line-nr and file name so ITRACE isn't needed.
3611 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3613 * gen-idecode.c (print_jump_until_stop_body): New function and
3614 idecode generation option. Instead of generating and calling

3639 as 1024,define. Add a new choice to the list - semantic - which
3640 will cause igen to generate instruction decode functions that
3641 include the corresponding semantic code.
3643 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3645 * configure.in: New option --enable-sim-line-nr (default enabled).

3648 used when generating the simulator code.
3650 * Makefile.in (sim_line_nr): Pass to igen.
3652 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

5025 Tue Dec 19 13:00:11 1995 Andrew Cagney <cagney@highland.com.au>
5027 * emul_chirp.c (chirp_emul_exit): Full out call.
5029 * device_table.c (htab_map_page): Wasn't handling byte swap when
5030 creating entries in the hash table.
5032 * device.c (device_tree_find_node): Allow primative wild-card match
5033 of device names with the path.
5035 FIXME: As mentioned earlier, the device stuff needs work to bring
5036 it into line with OpenBoot. Part of this work is rewriting the
5037 find_node function so that it behaves as specified in p1275.
5039 Mon Dec 18 19:58:56 1995 Andrew Cagney <cagney@highland.com.au>
5041 * emul_chrp.c (chirp_emul_write, chirp_emul_finddevice): add
5042 better tracing.
5044 * emul_chrp.c: Change return type of emul functions to int. Emul
5045 functions either return -1 or zero so unsigned was a bit
5046 dangerous.
5048 * inline.h (*), igen.c, dgen.c, *: Update INLINE macros so that
5049 they are paramaterised with the type of the function. Gets around
5050 the problem of `static' needing to come first with `attribute'
5051 comming last. Format declarations and definitions so that emacs
5052 doesn't get confused.
5054 Fri Dec 15 17:06:44 1995 Andrew Cagney <cagney@highland.com.au>
5056 * std-config.h (PSIM_INLINE): Add missing inline configuration
5057 control for the main loop.
5059 * mon.c (mon_print_info): If monitoring disabled still print out
5060 the number seconds used.
5062 * psim.c (run_until_stop): Don't monitor the cache misses when
5063 monitoring is disabled.
5065 * configure.in (sim_mon, sim_monitor): Correct typo - sim_mon ->
5066 sim_monitor for shell variable (or should that have been the other
5067 way around?).
5069 * vm.c (vm_synchronize_context): Fix wrong test for unsuported
5070 change in endian-mode.
5072 * std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE,
5073 SEMANTICS_INLINE): Add -DWITH_REGPARM=<n> option. Enables the
5074 __attribute__((__regparm(WITH_REGPARM))) for some functions.
5075 configure with --enable-sim-cflags="-DWITH_REGPARAM=3" (say).
5076 Unfortunatly it tickles a bug (gcc?) and can't be used.
5078 Mon Dec 18 13:36:06 1995 Michael Meissner <meissner@tiktok.cygnus.com>
5080 * device.c (device_tree_add_device): Make trace fprintf arguments

5087 Sat Dec 16 09:54:18 1995 Michael Meissner <meissner@wogglebug.tiac.net>
5089 * emul_netbsd.c (emul_netbsd_create): Deal with new BFD that
5090 changed how big/little endian support is recorded, while remaining
5091 compatible with the old BFD with #ifdefs.
5092 * emul_chirp.c (emul_chirp_create): Ditto.
5093 * emul_bugapi.c (emul_bugapi_create): Ditto.
5095 Fri Dec 15 15:55:56 1995 Michael Meissner <meissner@tiktok.cygnus.com>
5097 * std-config.h (MODEL_INLINE): Turn off INLINE_MODULE by default.
5099 * corefile.h: Delete declarations for unknown functions.
5100 * device.h: Ditto.
5101 * interrupts.h: Ditto.
5102 * interrupts.c: Ditto.
5104 Thu Dec 14 18:49:34 1995 Andrew Cagney <cagney@highland.com.au>
5106 * lf.c (lf_print_function_type): New function. Munges a function
5107 type so that the prefix (eg INLINE...) is inserted after the type
5108 but before any `*'.
5110 * igen.c: Change to output functions using this.
5112 Wed Dec 13 23:47:00 1995 Andrew Cagney <cagney@highland.com.au>
5114 FIXME: Emul CHIRP does not correctly implement the find device
5115 function.
5117 FIXME: Emul CHIRP and device do not implement device instance
5118 operations.
5120 Wed Dec 13 23:47:00 1995 Andrew Cagney <cagney@highland.com.au>
5122 * options.c (options_inline): Function to output meaningful
5123 description of the INLINE options.
5125 * configure.in (inline): Replace inline magic numbers with macro
5126 names. Map 1->LOCALS_INLINE and 2->ALL_INLINE.
5128 * inline.h, inline.c: update to use inline method.
5130 * std-config.h (CPU_INLINE), cpu.h, inline.h, inline.c: make cpu.h
5131 inline always.
5133 * std-config.h (EVENTS_INLINE): Inline events in psim.
5135 Wed Dec 13 22:01:21 1995 Andrew Cagney <cagney@highland.com.au>
5137 * device_table.c (htab_sum_binary): DMA binaries to correct byte
5138 within a page.
5140 Tue Dec 12 22:51:18 1995 Andrew Cagney <cagney@highland.com.au>
5142 * psim.c (psim_merge_device_file): Change `=' to `==', was this an
5143 error?
5145 Tue Dec 5 11:56:14 1995 Andrew Cagney <cagney@highland.com.au>
5147 * ppc-instructions (ppc_nr_mtcrf_crs, ppc_branch_conditional_name,
5148 ppc_function_unit_name): Simplify by declaring these arrays as
5149 pure and simple static (instead of STATIC_MODEL).
5151 Tue Dec 5 00:45:34 1995 Andrew Cagney <cagney@highland.com.au>
5153 * sim_calls.c (sim_create, sim_load), main.c (main), psim.c: Pass
5154 an options device into psim_create() so that options can be merged
5155 into the tree.
5157 * device.c (*add*): Change semantics so the add functions only add
5158 when the new device (or property) doesn't already exist. This
5159 allows merging of options and data.
5161 Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@highland.com.au>
5163 * Makefile.in (BASICS_H): Didn't include basics.h in the list of
5164 header files to depend on.
5166 Mon Dec 4 17:12:13 1995 Andrew Cagney <cagney@highland.com.au>
5168 * std-config.h: (*_MODULE): Extend the <module>_inline macro's so
5169 that they also allow control over static functions. Rewrite
5170 document to reflect this.
5172 * std-config.h: (INLINE): Simplify definition, the above and
5173 earlier changes to igen.h eliminate the need to be defensive about
5174 enabling the inline of static functions.
5176 * std-config.h: (SIM_ENDIAN_INLINE, BITS_INLINE): Document limited
5177 suport for inlineing of modules for all callers. Adjust relevant
5178 macro's so that DEFAULT_INLINE will enable this.
5180 * basics.h: Re-order #includes and definitions so that c-code for
5181 basic include files does not call functions delcared in later
5182 #includes.
5184 * basics.h (__attribute__), sim_callbacks.h: Move attribute macro
5185 to basics.h and add hack (include <stdio.h>) to try and bring that
5186 and other possible conflicting macros into scope much earler.
5188 * sim-endian.h,c (SIM_ENDIAN_INLINE) bits.h,c (BITS_INLINE):
5189 Change to use the updated inline definitions. If enabled
5190 immediately include the corresponding c-code so that it will inline
5191 for all modules.
5193 * inline.h, inline.c (SIM_ENDIAN_INLINE, BITS_INLINE): Remove
5194 these cases, moved to module specific header files.
5196 Sat Dec 2 18:37:51 1995 Andrew Cagney <cagney@highland.com.au>
5198 * vm.c, vm_n.c: Fix htab code.
5200 * vm.c (vm_data_map_read_buffer): Was using EA not RA when reading
5201 the data from core.
5203 * device.c: Fix htab create code.
5205 Fri Nov 24 23:10:09 1995 Andrew Cagney <cagney@highland.com.au>
5207 * bits.h, bits.c (EXTRACTED): Convert to function, fix - had &&
5208 instead of &.
5210 * sim-endian.h (SWAP_N), sim-endian-n.h, sim-endian.c: How
5211 embarasing - fix yet another bug in the swap code! Simplify
5212 everything by using more functions. Add host to big-endian byte
5213 swapping support.
5215 Fri Nov 24 23:10:09 1995 Andrew Cagney <cagney@highland.com.au>
5217 * devices.h, devices.c: delete, replaced by the files
5218 device_table.[ch] and device.[ch].
5219 * device_tree.h, device_tree.c: ditto
5221 * device_table.h, device_table.c: New files. Contain a table of
5222 devices.

5229 For convenience, change the printd functions into device_tree_add
5230 functions.
5232 * psim.c (create_*_tree): Use new device_tree create functions.
5234 * corefile.h, corefile.c corefile-n.h (core_n.h): Update to use
5235 the new device.h / device_table.h interface. Rename core_n.h to
5236 corefile-n.h to be consistent with other n files.
5238 * Makefile.in (run): add corefile-n.h to dependencies for
5239 corefile.
5241 * basics.h (device_instance), device.h, device.c, device_table.h,
5242 device_table.c: Add the concept of a device instance and operators
5243 on these instances - corresponds to ihandle in OpenBoot speak.
5244 Don't yet implement it.
5246 Tue Nov 14 12:27:08 1995 Andrew Cagney <cagney@highland.com.au>
5248 * emul_generic.h, emul_generic.c (emul_syscall_enter,
5249 emul_syscall_exit): rename from emul_enter_call /
5250 emul_exit_call. As only used by emul_do_system_call simplify
5251 associated code.
5253 * os_emul.h, os_emul.c, emul_generic.h: Correct and fill an
5254 os_emul interface.
5256 * os_emul.c, emul_bugapi.h, emul_bugapi.c, Makefile.in: Add
5257 preliminary hooks for a kernel mode rom emulation.
5259 * cap.h (new), cap.c (new): Capability data base. Some emulations
5260 pass object identifiers (capabilities?) to/from the simulated code
5261 (for instance the phandle in OpenBoot). The cap object is able to

5277 call the instruction-call emulation handler.
5279 * interrupts.c (system_call_interrupt): Call renamed
5280 os_emul_system_call function().
5282 * emul_netbsd.c: Update to interface to generic emulation. Since
5283 all its functions are called via a table don't worry about any
5284 inline.
5286 * emul_generic.h, emul_generic.c, spa-*(delete): Remove references
5287 and code for spa, no longer to be used.
5289 * psim.c (create_chirp_device_tree): Fill out what was previously

5295 * debug.h, debug.c: pte trace is made redundant by htab trace,
5296 delete it. Add vm to list of options. Simplify tracing output so
5297 lines are not as long.

5311 * sim-endian.h: Look at WORDS_BIGENDIAN to determine if the host
5312 is big endian or little endian. For SWAP_n, use htonl/htons if
5313 host is little endian, not big endian and if WITH_NTOH is defined.
5315 * configure{,.in} (--enable-sim-model-issue): Instead of defining
5316 0/1, define it to be MODEL_ISSUE_{PROCESS,IGNORE}. Add
5317 AC_C_BIGENDIAN to determine if the host is big endian or not.
5318 * config.in: Regenerate.
5320 * std-config.h (WITH_MODEL_ISSUE): Default to 0.
5321 (CURRENT_MODEL_ISSUE): Reference WITH_MODEL_ISSUE, and if that is
5322 0, use current_model_issue.

5351 * config.in: Regenerate.
5353 * cpu.h (CONST_ATTRIBUTE): Define as __attribute__((__const__)) if
5354 not already defined.
5355 (cpu_system): Use CONST_ATTRIBUTE, so that when we're not inlining
5356 the world, the optimizer has a fair chance of CSE'ing function
5357 calls.
5358 (cpu_{monitor,nr,registers,model}): Ditto.
5360 * std-config.h (MODEL_INLINE): If not defined, define as 1 if
5361 DEFAULT_INLINE is non-zero, 0 otherwise, rather than just the

5372 add -R to flags passed to igen.
5374 * igen.c (stdlib.h): Include if the system supplies one.

5379 #undef if -R.
5380 (lf_print_c_extraction): If -R and this is semantics, emit names

5382 the values into local variables.
5383 (lf_print_c_semantic_function): If -R, #undef all of the names
5384 defined in lf_print_c_extraction.
5385 (main): Recognize -R.

5440 better tracing support to the model specific information.
5442 Sun Nov 19 23:00:52 1995 Michael Meissner <meissner@tiktok.cygnus.com>
5444 * ppc-instructions (model data, model_busy): Rather than using a
5445 bit mask for the busy units, just use a char array. Also, only
5446 support 2 function units an insn can use, rather than a loop.

5470 * mon.h (count_type): New type for counters.
5471 * mon.c: Use count_type instead of unsigned.
5473 * ppc-instructions: Redo scheduling code once again. Make it all

5542 (mon_{read,write}): Count # of unaligned memory accesses.
5543 (mon_print_info): Switch to calling model_mon_info and
5544 model_mon_info_free instead of function_unit version. Print out
5545 number of unaligned reads/writes.
5547 * {ppc-instructions,igen.c}: More global changes to add model
5548 specific features.
5550 * inline.{c,h}: Provide for inlining options.c.
5551 * options.{c,h}: Ditto.
5552 * std-config.h: Add OPTIONS_INLINE.
5554 Tue Nov 14 04:47:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
5556 * Makefile.in (devices.o, main.o): Update dependency.
5558 * igen.c (gen_model_h): Use correct variable in loop.
5559 (gen_model_c): Use strcmp, strcasecmp.
5560 (gen_model_c): Use EXTERN_MODEL for arrays.
5561 (gen_model_h): Use STATIC_MODEL for arrays.
5562 (lf_print_c_semantic_function_header): Delete unused function.
5564 * main.c (cpu.h): Include cpu.h to get model.h.
5566 * inline.h ({EXTERN,STATIC}_MODEL): Define.
5568 Mon Nov 13 09:14:13 1995 Michael Meissner <meissner@tiktok.cygnus.com>
5570 * igen.c ({insn,model}_table_fields): Spell mnemonic correctly.
5571 (gen_itable_h,itable_c_insn): Ditto.
5572 (model support): Move model support around, add support for
5573 model-data, model-internal. Use annex field for model-macros
5574 now.
5576 * configure.in (--enable-sim-inline): If --enable-sim-inline=no,
5577 also define INLINE as nothing.
5578 * configure: Regenerate.
5580 * std-config.h (INLINE): Rather than nuking INLINE, only define it
5581 as __inline__ if any of the INLINE flags are non-zero.
5583 * options.c (print_options): Print out WITH_XOR_ENDAIN.
5585 Mon Nov 13 23:03:45 1995 Andrew Cagney <cagneyhighland.com.au>
5587 * ppc-instructions (rfi): Add missing code.
5589 * cpu.c (cpu_get_time_base): Fix calculation of current value of
5590 time base register.
5592 * ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
5593 m[tf]tb with m[tf]spr.
5595 * ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
5596 lower word.
5598 Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
5600 * std-config.h (INLINE, STATIC_INLINE): Was being set to static
5601 inline.. Only problem being that with ppc-opcode-simple this gave
5602 it the chance to inline all the idecode functions with potentially
5603 disasterous results on a 16mb PC. For moment hobble INLINE.
5605 * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
5606 default ...
5608 * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
5609 Firstly make them errors and secondly remove the options gcc-245
5610 doesn't reconize.
5612 Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
5614 * misc.c (zalloc), cpu.c (cpu_init), devices
5615 (console_io_read_buffer_callback, icu_io_read_buffer_callback,
5616 vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
5617 sim_calls.c (zalloc) : replace bzero() with memset().
5619 * emul_netbsd.c (write_direntries), psim.c (psim_read_register,
5620 psim_write_register): replace bcopy() with memcpy().
5622 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
5624 * configure.in: for --disable-sim-inline (--enable-sim-inline=no),
5625 force DEFAULT_INLINE to 0 rather then trusting the std
5626 configuration.
5628 Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
5630 * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
5631 generation of switch entries in tables - treat the same as
5632 cracking/semantic functions.
5634 * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
5635 of a boolean switch statement (field zero or non-zero).
5637 * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
5638 switch/table generation ability of igen.
5640 * igen.c (idecode_switch_leaf): Fix code output when a switch
5641 statement needs to look up a table.
5643 * igen.c (idecode_declare_if_switch): New function called from
5644 gen_idecode_c - need to declare any idecode switch functions
5645 before they are used in idecode tables.
5647 * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
5648 idecode_crack_insn): Add is_inline_function argument to code
5649 printing cracker functions which indicates if STATIC_IDECODE or
5650 STATIC_INLINE_IDECODE should be used for definition. For
5651 idecode_crack_insn (which implies not duplicating/expanding) don't
5652 declare function as inline - we assume that the only time this is
5653 code is generated is when things are being tested. For
5654 idecode_crack_leaf, make static (instead of INLINE) if the
5655 instructions parent is a table as function will always be called
5656 via a table.
5658 * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
5659 STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
5660 called directly, all others are called via a table.
5662 * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
5663 semantics_h_insn, semantics_h_function,
5664 lf_print_c_semantic_function, semantics_c_function): Add
5665 is_inline_function argument to lf_print_semantic_function_header
5666 to indicate if an inline or static function declaration/definition
5667 should be output. Depending on situtation call accordingly:
5668 functions (not instruction semantic routines) are always inline;
5669 Semantic routines are made inline when there is no icache (cache
5670 will contain the function address) and are duplicating (see above)
5671 and the parent of the instruction is a switch statement.
5673 * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
5674 and moved to insn_table_find_opcode_field.
5676 * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
5678 * igen.c (model_c_insn): Suggestion - document the name of the
5679 instruction on each line of the instruction model table.
5681 Fri Nov 10 00:44:38 1995 Andrew Cagney <cagneyhighland.com.au>
5683 * emul_netbsd.c (do_ioctl): Cleanup compilation.
5685 * sim_callbacks.h (__attribute__): Only define if not defined (was
5686 already defined on NetBSD host).
5688 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
5690 * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
5691 macro, indicates if the PowerPC's horrible XOR endian mode should
5692 be suported. Add to configure and make.
5694 * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
5695 (vm_instruction_map_read): If XOR endian, xor the address
5696 with a value from an xor table (indexed by size of access).
5698 * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
5699 set up xor table to xor if there is a conflict between the
5700 CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
5701 check of suported change of endian mode from cpu.c to vm.c.
5703 * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
5704 Hopefully added correct hack to handle XOR endian mode.
5706 FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
5707 little endian mode, the model accepts miss aligned transfers.
5709 FIXME: Need to create an `init' device that, during
5710 initializatioin for XOR mode, it mushes (XOR address) all the dma
5711 data before passing it on to the core for storage. Just like the
5712 real thing really.
5714 Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
5716 * devices.c (halt_io_write_buffer_callback): Use value written to
5717 halt device to determine exit status. Thus allowing
5718 success/failure of OEA tests.
5720 Wed Nov 8 00:10:38 1995 Andrew Cagney <cagneyhighland.com.au>
5722 * ppc-instructions (icbi): If icache present flush it.
5724 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
5726 * devices.c (htab_init_callback): Add code to create htab/pte.
5728 * devices.c (dma_file, file_init_callback, htab_init_callback):
5729 New function - Dma the named file into memory at the specified
5730 address. Use.
5732 * device_tree.h, device_tree.c (scand_*): New functions.
5734 Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
5736 * filter_filename.c, Makefile.in: Change so that only dependant on
5737 a very limited nr of files. Stops an unnecessary dependency.
5739 Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
5741 * core.c (core_map_find_mapping): Use cpu_halt rather than error
5742 to abort an access to an undefined address.

5770 Print out DEFAULT_MODEL as the first model if there any models
5771 specified, otherwise MODEL_NONE. Print out external decl for
5772 current_model. Print out decl for model_set.
5773 (gen_model_c): Add function model_set. Switch to use printable
5774 name for the model, not the internal identifier used.
5776 * psim.c (current_model): New global variable.
5778 * ppc-instructions: Add macros for flag defines. Switch first
5779 model so 604 is first.
5781 * main.c (main): Call model_set, not function_unit_model.
5782 * sim_calls.c (sim_open): Ditto.
5783 * sim_calls.c, Makefile.in: sim_calls.c now includes cpu.h.

6047 (mon_issue): Call function_unit_issue if function units are
6048 supported.
6049 (mon_print_info): Take psim * argument. Print out information
6050 from function_unit if available. Move read/write stats to always
6051 print, instead of printing if verbose > 1. Fix up plural
6052 vs. singular usage.
6054 * mon.h (mon_print_info): Update prototype.
6056 * psim.c (current_ppc_model): Add global variable.

6070 * table.c (config.h): Include config.h.
6072 * vm.c (om_virtual_to_real): Print pte_word_{0,1} so the compiler
6073 doesn't complain that they're unused.
6075 * vm_n.h (vm_data_map_read_N): Delete unused variable rval.
6077 Mon Nov 6 23:15:54 1995 Andrew Cagney <cagney@highland.com.au>

6083 * sim-endian.h (SWAP_N), sim-endian.c (_SWAP_1): Rename existing
6084 SWAP_<N> to _SWAP_<N> so that sim-endian.h can contain SWAP_N
6085 macro's as required.
6087 * sim-endian.c, sim-endian-n.h (new file): Move endian code into a
6088 debugable header file.
6090 * ppc-instructions (Byte-Reverse): Enable byte reverse

6103 * sim_calls.c (sim_open): Fix parsing of `target sim' options.
6105 * device_tree.c (device_tree_add_string): Wasn't saving the value
6106 of the string being entered into the tree.
6108 * psim.c (create_filed_device_tree): Not terminating string device
6109 names with a null.
6111 * psim.c (psim_create): Use `env' instead of
6112 `environment-architecture' to be consistent with configure.
6113 Reconize user/uea, virtual/vea and operating/oea.

6133 * ppc-instructions (data cache instructions): Make all data cache
6134 instructions nops instead of invalid instructions.
6136 * Makefile.in (CONFIG_CFLAGS): Add ALIGNMENT_CFLAGS and
6137 TIMEBASE_CFLAGS which weren't included.
6139 Thu Nov 2 08:54:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6141 * Makefile.in: Uncomment built file dependencies.
6143 * configure.in: Rewrite --enable-sim switch handling to use the
6144 autoconf builtins so it works correctly if the configure or
6145 Makefile.in files are modified and make decides to rebuild
6146 Makefile. Also document all of the --enable-sim switches
6147 supported. Check whether getrusage and sys/resource.h are
6148 supported.
6149 * config.in: Regenerate.
6150 * configure: Regenerate.
6151 * Makefile.in: Add support for all of the variables set with
6152 --enable-sim switches.
6154 * Makefile.in (clean): make clean now removes all built sources as
6155 well.
6157 * cpu.c: Use HAVE_STRING_H, HAVE_STRINGS_H, HAVE_UNISTD_H,
6158 HAVE_TIME_H, HAVE_SYS_TIMES_H, HAVE_SYS_RESOURCE_H defined in
6159 the generated config.h.
6160 * debug.c: Ditto.
6161 * device_tree.c: Ditto.
6162 * devices.c: Ditto.
6163 * dgen.c: Ditto.

6165 * igen.c: Ditto.
6166 * lf.c: Ditto.
6167 * misc.c: Ditto.
6168 * psim.c: Ditto.
6169 * registers.c: Ditto.
6170 * sim_calls.c: Ditt.
6171 * table.c: Ditto.
6174 * main.c (main): Call psim_print_info with verbose == 2.
6176 * mon.c (mon_print_info): Align the cpu number and number of
6177 instructions fields. Do not print an instruction category if the
6178 CPU did not execute any of those instructions. Print out number
6179 of reads and writes. If getrusage is supported, print out number
6180 of simulated instructins per second.
6182 * configure.in: Add support for --enable-sim-opcode=stupid.
6183 * configure: Regenerate.
6185 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
6187 * std-config (INLINE_DEVICE_TREE): Don't inline either of
6188 device_tree.c or devices.c. There is no significant gain.
6190 * configure.in, Makefile.in: add --enable-sim-icache=[0-9]* and
6191 IGEN_ICACHE macro.
6193 Wed Nov 1 23:46:59 1995 Andrew Cagney <cagney@highland.com.au>
6195 * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
6196 functions to convert between target and igen internal bit numbers.
6197 Make IO go through these functions. Add -b (bit size) and -h (high
6198 bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
6199 15 for a 16 bit instruction format with the msb given a number 15.
6201 Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
6203 * dgen.c (main): Was outputting optarg even when it was NULL.
6205 Tue Oct 31 23:48:33 1995 Andrew Cagney <cagney@highland.com.au>
6207 * vm_n.h (vm_data_map_load_N, vm_data_map_store_n), debug.h,
6208 debug.c: Add tracing of load/store unit (virtual) with -t
6209 load-store.
6211 Tue Oct 31 21:44:01 1995 Andrew Cagney <cagney@highland.com.au>
6213 * std-config.h (WITH_ENVIRONMENT): Add USER_ENVIRONMENT which does
6214 not include things such as the time base and events.
6216 * interrupt.c, sim_calls.c, cpu.h, vm.c, configure.in: Add UEA to
6217 all environment switches for above.
6219 * psim.c (psim_create): ditto - new device tree node name is
6220 /options/environment-architecture with values user, virtual and
6221 operating.
6223 Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
6225 * ppc-opcode-stupid: Third example of use of opcode table - this
6226 one expands all mtspr/mfspr and branch instructions. Appears to
6227 give about a 10% gain in performance if everything enabled. Also
6228 takes about 150mb of swap to build.
6230 Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6232 * emul_netbsd.c (do_exit): Print arguments and close parenthesis
6233 if tracing, since exit doesn't go through emul_exit_call.
6234 (do_read): Print arguments if tracing.
6235 (do_write): Ditto.
6236 (do_open): Ditto.
6237 (do_break): Ditto.

6240 (do_sigprocmask): Replace trace with printing arguments if
6241 tracing.

6246 (do_gettimeofday): Ditto.
6247 (do_getrusage): Ditto.
6248 (do_fstatfs): Ditto.
6250 * filter_filename.c: New file to provide filter_filename to strip
6251 the directory prefix from a file.
6252 * filter_filename.h: New include file to declare filter_filename.
6254 * debug.h: Include filter_filename.h.
6255 (TRACE,DTRACE,ERROR): Use filter_filename on __FILE__.

6258 (ASSERT): Use filter_filename on __FILE__.
6260 * igen.c (lf_print_my_prefix): Use filter_filename on the filename
6261 argument.
6263 * Makefile.in: Add filter_filename support.
6265 * ppc-instructions (dcbi, icbi): Make these NOPs rather than
6266 invalid instructions.
6268 * configure.in: Add support for more --enable-sim-* switches.
6269 Use config.make and config.hdr to write to Makefile and config.h
6270 respectively. Don't rewrite Makefile, just append to it.
6271 * configure: Regenerate.
6272 * config.{make,hdr}: New shell scripts.
6274 * Makefile.in: Remove all variables set by configure.in.
6275 (psim.o): Depend on $(BUILT_SRC) also.
6277 * emul_netbsd.c (do_gettimeofday,do_getrusage): When comparing an
6278 integer, use 0, not NULL.
6280 Tue Oct 31 15:20:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6282 * configure.in: Add support for --enable-sim-inline,
6283 --enable-sim-bswap, --enable-sim-cflags, --enable-sim-complex,
6284 --enable-sim-switch, --enable-sim-duplicate, --enable-sim-filter,
6285 and --enable-sim-endian switch to control various Makefile
6286 variables.
6287 * configure: Regenerate from configure.in.
6288 * Makefile.in: Add various Make variables that the various
6289 switches alter.
6291 * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
6292 and optimizing by default.
6294 Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
6296 * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
6297 make them functions again. Appears 2.6.3 is confused by just a
6298 macro.
6300 Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
6302 * ppc-endian.c (SWAP_8): Fix 8 byte swap!
6304 * psim.c (psim_create): Not correctly checking that runtime
6305 configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
6306 matched the compiled in ones.
6308 * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
6309 trace_semantics is now different to trace_idecode, the former
6310 checks the cache.
6312 Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
6314 * ppc-instructions (mtsrin): Missing instruction
6315 * ppc-instructions (mfsrin): Missing instruction
6316 * ppc-instructions (eieio): Missing instruction
6318 Tue Oct 24 20:55:29 1995 Andrew Cagney <cagney@highland.com.au>
6320 * build-psim: New shell script - see internals for usage,
6321 simplifies the process of building custom simulators.
6323 Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
6325 * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
6326 INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
6327 Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
6328 DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
6329 the instruction or data critical paths.
6331 * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
6332 the inclusion of device_tree.c/emul_generic.c.
6334 Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
6336 * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace
6337 system.[hc]. Start of suport for multiple emulations and
6338 emulation state (os_emul object).
6340 * emul_generic.[hc]: Start of code to implement proper system call
6341 tracing (from spy).
6343 Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
6345 * cpu.h, cpu.c (cpu_init): New function, zero the registers before
6346 the processor is started. Fixes problem of registers being
6347 undefined when restarting from within gdb.
6349 * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
6350 instruction cache (if present). Fixes problem of cpu caching gdb
6351 breakpoint instructions.
6353 FIXME: PSIM sometimes aborts calling error(), it should instead
6354 call sim_error() say which takes care of housekeeping such as
6355 saving the CIA before calling error.
6357 * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
6358 used when restarting a simulation because the latter has the
6359 unwanted side effect (well I as a kernel hacker think it is) of
6360 performing an isync when the instruction stream doesn't contain
6361 one.
6363 Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
6365 * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
6366 monitoring module. Counts both instructions issued and
6367 load/stores.
6369 * NOTE: mon does not contain to count instruction loads as this
6370 information is already available from the mon_issue() hook.
6372 * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
6374 * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
6375 a common monitor to each of the cpus. Delete
6376 cpu_increment_number_of_insns() and cpu_get_number_of_insns()
6377 replaced by copied code in mon.[hc].
6379 Sun Oct 22 18:42:45 1995 Andrew Cagney <cagney@highland.com.au>
6381 * sim_calls.c, main.c, psim.c (psim_create): always create
6382 `WITH_SMP' cpus. The actual number of CPU's active in a
6383 simulation run is taken from the device node: /init/smp (an
6384 integer). WITH_SMP changed to 2 (remember to put it back to 0).
6386 Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
6388 * system.c: More system call emulation. If code appears NetBSD
6389 specific, make conditional to being compiled on a NetBSD system
6390 (sigh).
6392 Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
6394 * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
6395 lf.[ch](new), table.[ch](new): Split into two generators - igen
6396 that outputs the instruction tables and dgen that outputs the spr
6397 tables. Add -f (filter out) flag to igen to filter out certain
6398 instructions (ex 64 bit ones) from the created tables. Include
6399 $(LIBIBERTY_LIB) in link options in case host lacks some libc
6400 functions.
6402 * NOTE: igen, since it was originally written for the
6403 PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
6405 * Makefile.in, std-config.h, ppc-cache-rules(new),
6406 ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
6407 cache-rule and opcode-rule tables from macros found std-config.h.
6408 Delete corresponding macro's from std-config.h.
6410 * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
6411 an table of all the instructions. Code to output a type
6412 enumerating all the instructin names.
6414 * igen.c(lf_print_c_semantic): Move call to increment instruction
6415 counter so that it occures _after_ the instruction has been fully
6416 validated, was double counting illegal/invalid instructions. Add
6417 conditional so only compiled in when WITH_PROFILE enabled (enabled
6418 by default).
6420 * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
6421 itable.h, count individual instruction types not just total,
6422 adjust reporting functions to output this.
6424 * ppc-instructions (64 bit Load Doubleword with Update Indexed):
6425 Had 32./ instead of 31./
6427 * ppc-instructions (64 bit Store Double Word Conditional Indexed):
6428 bitrot - updated to use newer CR register operators.
6430 * ppc-instructions (64bit Floating Convert from Integer
6431 Doubleword): Correct call to Round_Float().
6433 Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
6435 * basics.h: #include "sim_callbacks.h" earlier so that its
6436 prototypes are declared in all other header files.
6438 * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
6439 doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
6440 bits.h.
6442 * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
6443 Add size of buffer argument to functions writing a string into a
6444 buffer. Check for buffer overflow.
6446 Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
6448 * devices.h, devices.c, debug.h, debug.c: add macro's for tracing
6449 of each device. Make parameter names consistent so macros work.
6450 Use macro's in device functions.
6452 * device_tree.c, devices.h, devices.c: include path to device in a
6453 devices node when creating it.
6455 * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.
6457 * core.c: add tracing of core-device, adjust parameter names in
6458 core functions to be consistent with those in devices*.
6460 Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
6462 * debug.h, debug.c (trace_option): New function. Parses the trace
6463 option, updating the trace array.
6465 * debug.h, debug.c (trace_usage): New function. Outputs the list
6466 of all possible trace options.
6468 * sim_calls.c (sim_open), main.c (main): Use new trace_option() to
6469 parse trace options specified with the simpler -t flag. Adjust
6470 usage.
6472 * FIXME: basic parsing of command line options is still duplicated
6473 by main.c and sim_calls.c
6475 Thu Oct 26 10:42:28 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6477 * Makefile.in (clean): Delete *.i and *.out files.
6479 * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
6480 macros for either assignment or return. Fix SWAP_8 to use a
6481 union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
6482 (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
6483 that hardwired swapping on/off, let optimizer delete dead code.
6485 * main.c (main): Add printf that we caught a signal and print out
6486 the failing address.
6488 Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
6490 * Makefile.in: Remove tabs from otherwise empty line.
6491 Confuses many non-GNU versions of "make".
6493 Wed Oct 18 08:51:25 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6495 * Makefile.in (clean): Delete files produced by gen.
6497 Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6499 * gen.c (lf_print_c_semantic_function): Move counting # of
6500 instructions here so it works with caching.
6501 (gen_idecode_c): Move from here.
6503 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
6505 * gen.c, ppc-instructions, psim.c: Fix code for generating
6506 cracking instruction cache. Delete the code that cached just the
6507 result from doing an instruction lookup - this ran slower than no
6508 cache at all.
6510 Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6512 * Makefile.in (gen.o): Include $(INLINE_CFLAGS).
6514 * debug.h (ppc_trace): Rename from trace, to avoid a conflict with
6515 TCL when gdb is linked with the simulator.
6516 * debug.c (ppc_trace): Ditto.
6517 * sim_calls.c (sim_open): Change trace -> ppc_trace.
6518 * main.c (main): Ditto.
6520 * cpu.c (cpu_add_commas): Remove extra static.
6522 Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6524 * Makefile.in (psim.o): Now that inlines are turned on, make
6525 psim.o depend on all sources.
6527 * cpu.c (cpu_add_commas): New function to format a long with
6528 commas.
6529 (cpu_print_info): Use it to print number_of_insns.
6531 * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
6532 2, 4, and 8 bytes.
6533 (ENDIAN_N): If both target and host byte orders are known, don't
6534 bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
6536 * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
6537 to allow target specific H2T_n/T2H_n macros to be used.
6538 (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
6539 non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
6540 of the 3 instruction sequence that runs on 386s.
6542 * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
6543 specified on the compile line.
6544 (WITH_BSWAP): If not defined, define as 0.
6546 * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
6547 default inline support. Pass INLINE_CFLAGS when compiling.
6549 * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
6550 INLINE_DEVICES since GCC doesn't like inline functions that
6551 accept variable arguments.
6552 (stack_ioctl_callback): Make function just static because GCC
6553 doesn't like inline functions that accept variable arguments.
6555 * devices.h (STATIC_DEVICES): Define as empty if not defined.
6557 * inline.c: Correct pathnames of included C files to match current
6558 implementation.
6560 * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
6561 non-zero, define STATIC_DEVICES to be static.
6563 * std-config.h (INLINE): If GNU C and optimizing, define this as
6564 __inline__.
6565 (DEFAULT_INLINE): If not defined, define as 0.
6566 (ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
6567 ({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
6568 ({SPREG,IDECODE}_INLINE): Ditto.
6570 Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
6572 * ppc-instructions: Initial cut of floating point suport added.
6573 Of note include - use of host IEEE floating point instructions,
6574 use of PowerPC manual pseudo code to handle the FPSCR. It is not
6575 currently a pretty sight.
6577 * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
6578 merge into core.h, core.c, core_n.h. The type memory_map replaced
6579 with core_map. This removes a level of pointer indirection when
6580 translating an address.
6582 * memory_map.h, memory_map.c, memory_map_n.h: delete.
6584 * Makefile.in et.al (sorry): tweek to use new core, core_map and
6585 core.h.
6587 Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@highland.com.au>
6589 * sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
6590 most of the other functions in sim_calls.c.
6592 * basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
6593 Add macros to better cover up `generic' code. Makes it possible
6594 to step through the generic code!
6596 * vm.c, vm_n.h, Makefile.in: ditto
6598 Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
6600 * devices.h, devices.c, memory_map.h, memory_map.c: Changed
6601 callback interface so that there is a read/write buffer but no
6602 read/write_word. VEA default memory read/write handler sometimes
6603 couldn't resolve an access and of those some were for a memory
6604 fault and some were because gdb was making a bogus request.
6606 * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
6607 eliminate transfer_mode (raw or cooked) parameter from read/write
6608 buffer.
6610 Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
6612 * ppc-instructions (fmul, fmuls): correct instruction format - had
6613 FRB instead of FRC.
6615 Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@highland.com.au>
6617 * psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
6618 scand_*): new functions to parse/print fields in device names
6619 while hiding any machine dependency.
6621 * devices.c, psim.c: Change the stack init code so that it is
6622 handled by a device. Arguments passed across using a device ioctl
6623 (hack).
6625 * devices.h, devices.c: device ioctl callback changed to allow a
6626 variable number of arguments. This gives greater flexability and
6627 greater chance of bugs.
6629 Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
6631 * main.c (printf_filtered, error): Missing va_end() to close off
6632 variable argument use.
6634 * Makefile.in (tmp-gencode): comment out hack to get around some
6635 versions of make not handling files being created as side-effects.
6637 * gen.c (lf_open): Add -n (real_file_name) option. Specifies an
6638 alternative file name to use in output files for things like #line
6639 macros.
6641 Makefile.in (tmp-gencode): Use gen -n so that debug info is
6642 correct.
6644 * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
6645 Makefile.
6647 Sat Oct 7 22:40:59 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6649 * sim_calls.c (sim_set_callbacks): Define new function.

6658 instructions are executed.
6659 (cpu_increment_number_of_insns): New function to increment the
6660 number of instructions issued.
6661 (cpu_get_number_of_insns): New function to return the number of
6662 instructions issued.
6663 (cpu_print_info): New function to print cpu related information.
6664 At present, print the number of instructions executed.
6666 * gen_idecode_c: Emit call to cpu_increment_number_of_insns within
6667 idecode_issue.
6669 * psim.c (psim_print_info): New function to iterate over each of
6670 the CPU's calling cpu_print_info.
6672 * psim.h,cpu.h: Add new declarations.
6674 * sim_calls.c (sim_open): Add argument processing to add the same
6675 switches main.c accepts for the standalone processor.
6676 (sim_close): Call psim_print_info if -I.
6678 * main.c (main): Add comment saying to update sim_calls.c when
6679 adding switches. Add -I to call psim_print_info when done.
6680 (usage): Update usage message.
6682 Sun Oct 1 13:52:59 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6684 * main.c (printf_filtered): Correct to match new prototype.
6686 Sat Sep 30 20:47:05 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6688 * sim_callbacks.h (printf_filtered): Correct prototype.

6693 0x100000.
6694 (clayton_memory_size): Define as OEA_MEMORY_SIZE.
6696 * std-config.h (WITH_TRACE): Default to 1 now.
6698 * psim.c (write_stack_arguments): Don't write any stack arguments
6699 if OEA.
6701 * main.c (main): Switch to using getopt. Make -p also set
6702 trace_semantics. Make -a turn on all trace flags. Make -C turn
6703 on console tracing.
6705 * device_tree.c (create_option_device_node): Assume a program is
6706 OEA if the start address is < 4096, not just == 0.
6708 Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>
6710 * Makefile.in (maintainer-clean): New synonym for realclean.
6712 Sun Sep 10 10:23:56 1995 Michael Tiemann <tiemann@axon.cygnus.com>
6714 * registers.c (register_description): Add gdb synonyms for cr
6715 (cnd) and msr (ps).
6717 Fri Sep 8 13:16:10 1995 Ian Lance Taylor <ian@cygnus.com>
6719 * Makefile.in (install): Don't install in $(tooldir).
6721 * configure.in: Call AC_CONFIG_HEADER. Don't try to use
6722 bfd/hosts/*.h file or bfd/config/*.mh file. Call AC_PROG_CC and
6723 AC_PROG_RANLIB. Substitute in values for CFLAGS, HDEFINES, AR,
6724 and CC_FOR_BUILD. Call AC_CHECK_HEADERS for various header files.
6725 Touch stamp.h if creating config.h.
6726 * configure: Rebuild.
6727 * config.in: New file, created by autoheader.
6728 * Makefile.in (AR): Define as @AR@.
6729 (CC): New variable, defined as @CC@.
6730 (CFLAGS): Define as @CFLAGS@.
6731 (CC_FOR_BUILD): New variable, defined as @CC_FOR_BUILD@.

6736 (clean): Remove config.log.
6737 (distclean): Remove config.h and stamp-h.

6745 Fri Sep 8 09:51:03 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6747 * configure{,.in}: Don't include sysdep.h from bfd, since bfd no
6748 longer provides it.
6749 * basics.h (sysdep.h): Don't include it.
6750 * Makefile.in (BASICS_H): Remove sysdep.h.
6752 Wed Sep 6 13:25:42 1995 Andrew Cagney <cagney@highland.com.au>
6754 * core.c (core_add_data): First growth of bss was being put at
6755 wrong address (0) instead of &end.
6757 * core.c (core_add_stack, core_add_data): Was not handling case
6758 where bss/stack is grown across the current end-of-{bss,stack}.
6760 Wed Sep 6 00:46:10 1995 Andrew Cagney <cagney@highland.com.au>
6762 * system.c (system_call): Fix SYS_break - was aligning bss to a
6763 page boundary instead of just an 8 byte one; On first call sbrk(0)
6764 != sbrk(0).
6766 Thu Aug 24 14:48:54 1995 Michael Meissner <meissner@tiktok.cygnus.com>
6768 * Makefile.in (install): Fix install rule.

6772 * system.c (system_call): Add read support.
6774 * main.c (main): -t sets trace_device_tree. Correct usage message
6775 to current reality.
6777 * device_tree.c (update_memory_node_for_section): Make tracing
6778 output line up. If not code or readonly, assume that the section
6779 is a data section and has read/write permissions. Add readonly
6780 support.
6782 * core.c (create_core_from_addresses): Print end address in traces
6783 and make tracing output line up.
6785 * Makefile.in: Rewrite from Makefile to work with the Cygnus
6786 environment, and support compiling in a different directory than
6787 the sources reside in.
6789 * ppc-endian.h: Rename from endian.h so that it doesn't get
6790 confused with /usr/include/sys/endian.h on Linux. Add Linux
6791 endian support.
6793 * ppc-endian.c: Rename to be consistant with ppc-endian.h.
6794 Include ppc-endian.h, not endian.h.
6796 * basics.h (sysdep.h): Include sysdep.h that configure makes.
6797 Include ppc-endian.h, not endian.h.
6799 * std-config.h: Rename from ppc-config. Put #ifndefs around most
6800 configuration macros, so they can be overridden via CFLAGS. By
6801 default, turn off tracing.
6803 * configure.in: Clone from other simulator targets.
6804 * configure: Generate via autoconf from configure.in.
6806 Sat Aug 19 09:05:32 1995 Andrew Cagney <cagney@highland.com.au>
6808 * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
6810 * interrupts.c (data_storage_interrupt): allow stack to grow by
6811 upto one MB per increment.
6813 * ppc-instructions: divw was computing rA / rA not rA / rB
6815 * main.c (main): really stupid. Wasn't exiting with correct status
6817 Fri Aug 18 00:38:01 1995 Andrew Cagney <cagney@highland.com.au>

6822 finishes.
6824 Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney@highland.com.au>
6826 * device_tree.c (create_option_device_node): Alignment rules (at
6827 least for the moment) now are for strict alignment only for LE OEA
6828 mode. (Because of compiler problems).
6830 * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
6832 Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
6834 * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
6835 forgot to return.
6837 * system.c (system_call): didn't page align break argument before
6838 determining increment break increment.
6840 * psim/ppc: Re-arange entire directory structure so that
6841 everything lives in the one directory. While a pain for cleaning,
6842 makes building across multiple architectures much simpler.
6844 * devices.c, device_tree.c: Added code that provides a simple
6845 illustration of how an interrupt control device could be
6846 implemented.
6848 * devices.c: Added code so that the dumb console device can read
6849 (from stdin) as well as write to stdout.
