170 the macro name and the arguments in a use of such a definition.
174 * sim_calls.c: Doc fix.
175 (sim_fetch_register, sim_store_register): Call

238 * emul_generic.c (emul_add_tree_options): Only require strict
239 alignment if it was explicitly requested at configuration time.
240 Don't make it the default for little-endian machines.

242 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
243 THRM2, THRM3): Plop in the MPC750 SPR registers.
244 (DABR): This is weird. This was HID5, but the PPC spec says this
245 should be DABR; why did some random processor use it for something
246 else? The HID5 entry dates back to the original checkin of the
247 simulator code in 1995, so remove it.
248 * sim_calls.c (register_names): Delete this; since the user can
249 now change GDB's list of register names dynamically, we can't
250 pretend there's a static mapping here.
251 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
252 function to get the register name. That ought to be accurate.
253 However, we're changing a compile-time dependency (using the
254 REGISTER_NAMES macro) into a link- and run-time dependency
255 (calling REGISTER_NAME, which happens to be a function call on the

262 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

280 poll the external environment.
284 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
285 fractional type, so that quiet NaN's aren't treated like
290 * table.c (table_open): For cygwin hosts, we need to use the
291 return value from the read routine as the number of bytes to
292 process. This apparently is due to text-mode vs binary-mode. If
293 the mounts are done text-mode, then the size returnedby fstat()
294 may be different than the number of bytes "read" in text mode.
298 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
305 * emul_{netbsd,unix}.c: Update copyright year.
309 * sim_calls.c (sim_fetch_register, sim_store_register):

317 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
321 * Makefile.in: The run target depended on a target psim$(EXEEXT),
322 but there was no such target, only plain psim. So I changed the
323 run target to depend on psim.
327 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
328 now defined in ../common/aclocal.m4, and the double definition causes
329 problems with AC_SUBST of EXEEXT.
330 * configure: Regenerate.
334 * aclocal.m4: new file for AM_EXEEXT macro
335 * configure.in: call AM_EXEEXT

652 (device_add_ihandle_runtime_property): Update.

661 Augment each extracted field with a comment citing the codes
662 origin. Should simplify tracking down incorrect cache
667 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
668 works for normal and boolean table entries.
670 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
671 valid. Handle this just like *_{read,write}_register now handles
676 * events.c (insert_event_entry): Correct loop termination
681 * psim.c (psim_options): Add new option -c for max-iterations or
683 (psim_usage): Document.
684 (psim_max_iterations_exceeded): New function, abort simulation if
685 max iterations exceeded.
687 * gen-idecode.c: Re-work the table lookup code so that it assumes
688 that the entry is a leaf by default. Simplify the boolean table
689 entry code so that it involves a mask + test instead of shift +
692 * gen-idecode.c: Correct generated igen body so that it no drops
693 or doubles clock interrupts.

730 * When performance monitoring is disabled, it is still possible to
731 determine the simulation speed by looking at the number of elapsed
732 ticks recorded by the event queue.
734 * psim.c (psim_write_register, psim_read_register): Force the cpu
735 to zero when it is either of `-1' or `nr_cpus'. In both cases the
736 next cpu would be zero any way.
738 * mon.c (mon_print_info): If possible, print the system cycle
739 performance. This is an indication of the number of instructions
744 * The code to allow an event queue to be updated during a signal
745 was missing. For main.c, a cntrl-c simulation termination wasn't
748 * The simulation would not correctly restart if an event requested
749 that the simulation be halted.

752 include a level vis -i2.
753 (psim_usage): Document.

804 could be overridden by hw_trace.
806 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
808 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
809 debug.c. It could be much simpler.
813 * Some devices support removable media. Add hooks to the disk
814 device so that it supports this.

869 was too compilicated. The cache table did not allow values to be
870 computed from cache entries. #defines could only be used when a
871 cache was present, remove the restriction.
873 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
874 scratch variable is defined when a cache entry is beinf
875 filled. Change the definition of a COMPUTE variable to be defined
876 when the cache entry is being used.
877 * gen-icache.c: Update.

895 * configure.in (enable-sim-icache): Clarify description. Make
896 #define one of the defaults regardless of the cache. Probably
897 should revamp and add a separate option.
901 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
903 (pk_disklabel_create_instance): Partition 1..4 are valid - not
905 (is_iso9660): New function, verify a CD9660 File system.
906 (pk_disklabel_create_instance): Start expanding so that active
907 partition selection is supported.
911 * The cap object was retaining a reference to the instance of a
912 device after it was deleted. Instead add and remove cap's from the

951 size as arguments. These may be multi cell values. Initially fix
952 the memory code so that they check/detect this. Leave the

2172 (Move To FPSCR Bit 1): Ditto.
2176 * std-config.h (SEMANTICS_INLINE): By default, mask out the
2177 inlining of semantic functions from DEFAULT_INLINE. Almost all

2209 always update the cache_entries semantic and address fields.
2211 * gen-idecode.c (print_idecode_switch_illegal): Include a break
2212 when generating illegal instructions. This was commented out
2213 which is a hangover from looking a at switch statements generated
2214 using indirect jumps.
2218 * igen.c (print_my_defines): Replaces print_define_my_index.
2219 Print both a definition for MY_INDEX and MY_PREFIX.
2220 * gen-icache.c (print_icache_function): Adjust.

2233 * ppc-instructions (convert_to_integer, Floating Round to
2234 Single-Precision, Floating Convert from Integer Doubleword): Use
2235 LABEL and GOTO instead of the recently added switch statements.

2246 that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE.
2248 * configure: rebuild.
2252 * configure.in (--enable-sim-hardware, --enable-sim-packages): New
2253 configuration options. Let the user specify the packages or
2254 hardware devices that are to be included in the build. Makes it
2255 possible for user packages to be specified.
2257 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
2258 hardware instead of checking it using ls. configure.in should
2259 have taken care of any problems.

2264 * psim.c (psim_options): Enter the argument to the memory size
2265 option directly into the device tree. Was using atol() which is
2266 dangerously non portable.
2270 * configure.in (icache): Extend icache flag to include an insn
2271 option. If specifyed the insn - aka instruction - is included in
2272 the instruction cache. Make this the default.
2273 * configure: re-generate.
2275 * igen.c (main), igen.h: Add option -S - inSn - for specifying
2276 that the instruction should be included in the icache.
2278 * gen-icache.c (print_icache_body): If enabled, output code to put
2279 the instruction into the icache.
2280 (print_icache_struct): If enabled, add insn to the icache struct.
2284 * Makefile.in (BUILD_CFLAGS): Include -g when building the
2289 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2290 the strict-alignment option when hardwired for non-strict

2297 * ppc-instructions: Adjust so that references are to MY_INDEX and
2302 * gen-idecode.c: Output the complete run_until_stop function
2303 instead of just the code to handle a single instruction issue.

2306 * std-config.h: Change psim.c so that it isn't inlined (as this is
2309 * psim.c (run_until_stop): Delete the old run_until_stop function
2310 instead calling the idecode_run and idecode_run_until_stop
2311 functions that gen-idecode.c is now creating.
2315 * dgen.c: Maintenance - update to use new features found in lf.c.
2317 * filter_filename.c (filter_filename): Maintenance - make the

2335 match new interface.
2337 * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
2338 corresponding call to ITRACE so that it still matches.
2340 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2341 of ITRACE. The CPP line directives would have previously set the
2342 line-nr and file name so ITRACE isn't needed.
2346 * gen-idecode.c (print_jump_until_stop_body): New function and
2347 idecode generation option. Instead of generating and calling
2348 separate functions containing the semantic and icache code
2349 generate a single monolythic function and use goto's (and GCC's
2350 indirect jump) to move between code blocks.
2352 * Makefile.in: Add sim_jump flag to those passed to igen.
2354 * configure.in: New option --enable-sim-jump (default disabled)

2373 will cause igen to generate instruction decode functions that
2374 include the corresponding semantic code.
2378 * configure.in: New option --enable-sim-line-nr (default enabled).
2379 Enable/disable the inclusion of CPP line directives in the
2380 generated files. Such directives refer back to the source files
2381 used when generating the simulator code.
2383 * Makefile.in (sim_line_nr): Pass to igen.
2387 * igen.c (main): Revamp the options so that more letters are

2427 * ppc-opcode-flat: Ditto
2429 * filter.h, filter.c: New files. Separate the opcode filter table
2430 reading code from the rest of igen.c. Re-design the filter so that
2431 it works inclusivly not exclusivly.
2432 * igen.c: Remove the opcode filter table loading code.
2433 * Makefile.in (filter.o): Adjust
2434 * configure.in: Adjust filter flag so that default includes 32bit
2436 * ppc-instructions: Clean up filter fields so that only in use
2437 entries are specifed (ie delete `be').
2439 * misc.c (name2i, i2name): New function. Map between a string and

2458 * psim.c (psim_read_register): Add call to new function
2459 model_get_number_of_cycles().
2463 * device_table.h: Don't pass the parent device into a devices
2464 create function. This makes the create function consistent with
2466 * device.c (device_template_create_device): Ditto
