        * ppc-macosx-tdep.c (ppc_gdbarch_init, ppc_macosx_init_abi_64):
        long doubles are 16 bytes, not 8.  gcc 3.3 would emit 8 byte
        long doubles, but gcc 4 emits 16 byte doubles.  We've transitioned
        the majority of our developers off of 3.3.

        * macosx-nat-dyld-process.c (dyld_libraries_compatible): Modify
        Klee's last change -- if two dyld_objfile_entries appear to be
        compatible but aren't similar, they aren't compatible.  (don't
        assert here -- we can have a plug-in with the same name loaded
        twice at two different addresses.)

2005-10-13  Klee Dienes  <kdienes@apple.com>

        * macosx-nat-inferior.c (do_check_is_thread_unsafe): Don't use

        * macosx-nat-inferior.c (do_check_is_thread_unsafe): Use
        get_current_frame(), not parse_frame_specification, to avoid
        trashing parser state.  Use pid_to_thread_id (inferior_ptid),
        instead of assuming a thread was passed in.  Fixes
        <rdar://problem/4287454>

2005-10-11  Jason Molenda  (jmolenda@apple.com)

        * macosx-nat-cfm.c (cfm_update): If we fail to read the cfm cookie

        always get a valid fpu context from the inferior.
        (i386_macosx_store_fp_registers): Because we always get a valid

        none of the objfiles are really present.)
	* macosx-nat-dyld-process.h: Prototype for above.

	* macosx-nat-dyld.c (macosx_dyld_mourn_inferior): A function called

	* macosx-nat-dyld-path.c (get_framework_pathname): Apply patch from 
	Eric Albert <ejalbert@apple.com> to recognize .bundle's correctly.
	Minor reworking of the functions variables/etc by me.

2004-12-02  Jason Molenda  (jmolenda@apple.com)

	Remove dyld_index from the dyld_objfile_entry.  I don't think it does
	anything except point at the mach_header of an image which dyld_addr
	already does.  So out it goes.

	* macosx-nat-dyld-info.c (dyld_objfile_entry_clear): Ditto.
	(dyld_objfile_entry_compare): Don't use dyld_index in comparisons.

	dyld_index.
	(dyld_info_read): Don't initialize dyld_index.

2004-11-29  Jim Ingham  <jingham@apple.com>

	* ppc-macosx-frameinfo.c (ppc_parse_instructions): Fix a typo in
	the stdu if branch.  And add to the terminal "scan-ahead" section
	a bit looking for setting up the stack frame.  Since we are now
	relying on unwinding r30 to get the frame, getting this bit of
	info is more important.
	* ppc-macosx-tdep.c (ppc_frame_find_prev_fp): Do some sanity checking
	on the frame pointer you have just unwound, and it if seems bad, fall
	back on the stack pointer.

	maybe a comment or two.  The usual.

2004-11-29  Jason Molenda  (jmolenda@apple.com)

	* macosx-nat-dyld.c (macosx_dyld_init): Make macosx_locate_dyld call
	a little clearer.  Always look up the dyld info even if it's in
	the same location as the past - maybe not necessary, but I don't
	trust this optimization without knowing more about what's going on.
	(macosx_solib_add): If we're called without a running inferior
	(i.e. we can't find dyld), don't try to read the non-existant dyld's
	data structures.
	(dyld_info_read_raw_data): Short-circuit a do-nothing call to this
	func.

2004-11-29  Jim Ingham  <jingham@apple.com>

	* ppc-macosx-tdep.c (ppc_sigtramp_frame_cache): Offset the registers
	after CR in the save area, that is always stored in an 4 byte int 
	regardless of the size of the GPR's.  
	(ppc_sigtramp_frame_prev_register): Also distinguish 32 bit and
	64 bit signal context areas here.
	* ppc-macosx-frameinfo.c: Add sigtramp_gp_save_size to pass info
	about what the save size is.
	
2004-11-23  Jason Molenda  (jmolenda@apple.com)

	* macosx-nat-dyld.c: Switch over to the new dyld interface for
	receiving notifications about image files loaded in the inferior
	process.  Run the file through gdb_indent.  There remains work to
	do, but the basics are in place.
	* macosx-nat-dyld.h: Same.

	* macosx-nat-dyld-info.c: Add comments.  Beginnings of my pogrom
	against the fear of signed types for counting small quantities which
	pervades this entire subdirectory.  Remove tabs.
	* macosx-nat-dyld-info.h: Same.
	* macosx-nat-dyld-path.c (strsave): Wow, a macro alias for xstrdup
	in one file.  Gone.  Small formatting cleanups.
	* macosx-nat-dyld-process.c: Add comments.  Removed unsigneds.  Fix
	a couple small mistakes gdb_indent made.
	* macosx-nat-dyld-process.h: Same.

2004-11-23  Jim Ingham  <jingham@apple.com>

	* ppc-macosx-frameinfo.c: (ppc_parse_instructions): Catch the
	case where std is used to save the link register.
	Also recognize std for saving the GPR's.
	And recognize stdu for updating the stack pointer.
	(ppc_frame_function_properties): When overriding the prologue
	parser for frames up on the stack, set the lr store offset
	to a value appropriate to the architecture.
	* ppc-macosx-tdep.c (ppc_frame_prev_register): When reading the 
	frame pointer, take architecture into account.

2004-11-22  Eric Albert <ejalbert@apple.com>

2004-11-18  Jim Ingham <jingham@apple.com>

	* macosx-nat-inferior.c (macosx_handle_exception): Cast
	exception_data to an unsigned int first, THEN to a CORE_ADDR.
	This keeps it from getting sign extended.
	
2004-11-16  Jason Molenda  (jmolenda@apple.com)

	Revert change from 2004-11-10; it doesn't work for host cross host

	(store_inferior_registers): Ditto.

	* ppc-macosx-tdep.c (ppc_unwind_dummy_id): Use register size,
	not addr bit.
	* (ppc_register_virtual_type): Since we always tread the registers

	of the relocation struct when relocating the objfile; don't set
	the objfile field explicitly.  Allocate a fresh malloc()-based
	memory allocator, and fresh obstacks, so that other code can add
	new types to the newly-consed objfile.  Generate the section table
	after reading in the cached objfile.
	* cached-symfile.h (struct relocation_context): Add new 'objfile'
	field, to allow the relocation code to munge objfile pointers to

2003-04-15  Jim Ingham (jingham@apple.com)

	This set of changes are the Mac OS X side of the changes to only

	set unless the objfile they are set in changes.

	* macosx-nat-dyld-process.c (dyld_prune_shlib): Call
	tell_breakpoints_objfile_changed.
	(dyld_shlibs_updated): No need to call breakpoint_re_set here.

	This change moves handling the exeception catchpoints to generic

	* macosx-nat-dyld.c (macosx_solib_add): Don't update the catchpoints
	here.  Marking the solib as changed will trigger it in generic code.

2003-04-11  Jim Ingham (jingham@apple.com)

	* ppc-macosx-frameinfo.c: Set max_skip_non_prologue_insns to 2.
	10 is excessive, since we are just looking for the FIRST non-prologue
	instruction...
	* (ppc_parse_instructions): This was returning the last recognized
	prologue instruction, it should return the first body instruction.
	* (ppc_frame_cache_properties): Pass body_start to 
	ppc_parse_instructions, not function_end.  That really is the bounds
	of the prologue scan, and if we got it wrong in 
	ppc_frame_cache_boundaries, looking further won't help us now.

2003-03-24  Jim Ingham (jingham@apple.com)

	* ppc-macosx-frameops.c (ppc_frame_saved_regs): The saved_regs for the 
	PC is expected to be the ADDRESS at which the PC is stored, not the
	value of the PC.  Only the SP is stored by value here.  Make it so.  
	* ppc-macosx-tdep.c: Move #define of DEFAULT_LR_SAVE to
	ppc-macosx-regs.h.
	* ppc-macosx-frameinfo.c: Ditto

	Handle relocating shared libraries who have already had an objfile
	loaded.
	(dyld_load_symfiles): Call dyld_load_symfile for shared libraries
	who need their symbols relocated.
	(dyld_libraries_compatible): Objfiles are now considered
	compatible even if they are at different addresses (i.e., one may
	need to be relocated).

2002-11-15  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-process.c (dyld_load_library): Remove "reading
	from memory" parts of the error messages; they weren't always
	true.  Don't check for e->dyld_valid with an assert; just don't
	try to read from memory if it's not set.

	(dyld_purge_cached_libraries): Use dyld_update_shlibs to handle
	the update portion of the purge.
	* macosx-nat-dyld.c (update_section_tables): Re-implement.  Now
	uses target_resize_to_sections instead of managing to_sections by
	hand.

	const unsigned int PPC_SIGCONTEXT_SP_OFFSET = 0xa4;

2002-11-06  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (macosx_solib_add): Don't assume that entry
	pointers will remain valid after a call to dyld_update_shlibs (it
	can pack the entries).
	
2002-11-06  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (macosx_init_dyld): Only add the
	dyld_reason_executable entry if symfile_objfile is set. 
	* macosx-nat-dyld-process.c (dyld_load_symfile): If an executable,
	check to make sure it matches symfile objfile.  Propagate back any
	changes to e->objfile to symfile_objfile (i.e., replace the
	special-case handling with the standard mechanism).
	
2002-11-06  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-process.c (dyld_load_library): If an executable,
	check to make sure it matches symfile objfile.  Propagate back any
	changes to e->objfile to symfile_objfile.
	(dyld_load_symfile): Ditto.
	(dyld_remove_objfile): Ditto.
	(dyld_remove_objfiles): If an executable, check to make sure it
	matches symfile objfile.
	* macosx-nat-dyld.c (macosx_init_dyld): Clear the objfile/bfd for
	any existing executable entries.  Set the objfile/bfd field for
	the new executable entry to include all available information.
	
2002-11-06  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-info.c (dyld_next_allocated_shlib): Formerly

2002-11-02  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (dyld_stop_on_shlibs_added): New variable.
	Causes macosx_solib_add to return a library-changed indicator if a
	shared library is added (using the "=shlibs-added notification, as
	opposed to "=shlibs-updated").  Without this variable set,
	macosx_solib_add will return zero even if a shared library is
	added.
	(dyld_stop_on_shlibs_updated): New variable.  Like
	dyld_stop_on_solibs_added, but corresponds to a full shared
	library update (using the "=shlibs-updated") notification.
	(macosx_solib_add): Honor dyld_stop_on_shlibs_added.  Rely on
	macosx_dyld_update to honor dyld_stop_on_shlibs_updated.
	(macosx_dyld_update): Honor dyld_stop_on_shlibs_updated.
	(_initialize_macosx_nat_dyld): Export dyld_stop_on_shlibs_added
	and dyld_stop_on_shlibs_updated as 'set/show sharedlibrary
	stop-on-shlibs-added' and 'set/show sharedlibrary
	stop-on-shlibs-updated'.
	
2002-11-02  Klee Dienes  <kdienes@apple.com>

	* symread.c (sym_read_type): Use bfd_bread instead of bfd_read.
	
2002-11-01  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (dyld_info_read): Remember the saved space for
	the executable as an index into the info, not a pointer ---
	otherwise it can end up pointing to stale data if
	dyld_objfile_entry_alloc ends up reallocating the array.
	
2002-11-01  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-process.c (dyld_prune_shlibs): New function.
	Remove all shared libraries in 'old' that match the entry 'n'.
	(dyld_merge_shlibs): Update to use dyld_prune_shlibs.  Algorithm
	is (finally) reasonably simple --- copy the old shlibs that can be
	re-used; purge the ones that shouldn't be cached; cache the rest.
	Update prototype to be "update from 'old' into 'new'" (previously
	it was "update from 'old' into 'result' according to 'new'").
	* macosx-nat-dyld-process.h (dyld_prune_shlibs): Update prototype.

	* macosx-nat-dyld.c (macosx_init_dyld): Update to new prototype
	for dyld_merge_shlibs.
	(macosx_dyld_update): Ditto.
	(dyld_add_symbol_file_command): Ditto.

	(dyld_set_load_state_command): Ditto.
	
2002-10-31  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-info.c (dyld_objfile_entry_clear): Initialize
	dyld_length to 0.
	(dyld_resolve_shlib_num): Swap the order of "user" and non-user
	shared library ordering.  The new order in all cases should be
	exec, dyld, dyld libraries, cached objects, user libraries.
	(dyld_entry_shlib_num): Remove the section for counting
	user-loaded libraires (they now come last).
	(dyld_print_entry_info): Print a "!" in the "reason" field if the
	objfile is invalid, rather than crashing.
	(dyld_print_shlib_info): Reformat the table header.  Increase the
	minimum library field width to 12, to accomodate the new table
	headers (in practice the field is always that long anyway).  Swap
	the order of "user" and non-user shared library ordering.

	* macosx-nat-dyld-io.c (extend_vma): Remove.
	(inferior_bfd_generic): No longer call extend_vma; rely on offset
	to be properly sign-extended.

	* macosx-nat-dyld-process.c (dyld_objfile_allocated): Export.
	(dyld_libraries_compatible): Libraries are incompatible if
	_either_ offset is non-zero and not equal to the other offset
	(previously both had to be non-zero).
	(next_allocated): New function.  Returns the next index into
	'info' that points to an allocated shared library entry.
	(DYLD_ALL_OBJFILE_INFO_ENTRIES): New macro.  Iterates 'o', 'n'
	through the allocated shared library entries of 'info'.
	(dyld_merge_shlib): No longer tries to handle removal of
	old/cached libraries; only handles copying of objfile information
	from the previous info into the new entry (if possible).
	(dyld_merge_shlibs): Re-implement (see comments in
	dyld_merge_shlib).  No longer call dyld_remove_objfiles or
	dyld_objfile_info_pack (these have been moved into
	dyld_update_shlibs).
	* macosx-nat-dyld-process.h (dyld_objfile_allocated): Add prototype.

	* macosx-nat-dyld.c (struct dyld_raw_info): Revert 'slide' to a
	CORE_ADDR.  We don't know whether a slide of a 32-bit address will
	be positive or negative until we know the address upon which it
	operates.
	(dyld_info_process_raw): Revert 'slide' to a CORE_ADDR.
	(macosx_init_dyld): Move the 'exec' entry to the top of the info
	list.
	(extend_slide): New function.  Given a slide and an address,
	sign-extend the slide as appropriate to operate as a CORE_ADDR.
	(dyld_info_read_raw): Read 'slide' as an unsigned integer; instead
	use extend_slide to extend it once we have read the address.
	(dyld_info_read): Reserve space for the 'exec' entry; fill it with
	the first entry of dyld_reason_executable ready by dyld.

2002-10-31  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (macosx_solib_add): Recognize DYLD_MODULE_*,
	DYLD_PAST_EVENTS_END, and DYLD_IMAGE_REMOVED.  Do a full dyld
	update on DYLD_IMAGE_REMOVED; ignore all other events.  For
	unknown events, emit a warning and do a fulld dyld update.
	(macosx_dyld_update): Only emit a shlibs-updated notification if
	the library state has actually changed.

2002-10-31  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-inferior-debug.c (macosx_debug_regions): Update to
	take a start address and maximum number of regions to be printed.
	Coalesce adjacent regions with identical permissions into a single
	printed line; print the number of sub-regions as part of the line.
	Shorten output to fit in a 100-character line (still too long, but
	a big improvement).
	(macosx_debug_region): Replace with a call to macosx_debug_region.
	* macosx-nat-inferior-debug.h (macosx_debug_regsions): Update
	prototype.  * macosx-nat-info.c (info_mach_regions_command):
	Update to new interface for macosx_debug_regions.

2002-10-30  Jim Ingham   <jingham@apple.com>

	* macosx-nat-dyld-path.c (dyld_resolve_image): Handle the case
	where the dyld name contains @executable_path.

2002-10-29  Klee Dienes  <kdienes@apple.com>

	* i386-macosx-tdep.c: Remove extraneous definitions of ss and st:
	they were a useless cut-and-paste accident, and now break the i386
	build.

2002-10-28  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-watchpoint.c: Include macosx-nat-watchpoint.h.
	(hppa_insert_hw_watchpoint): Make static.
	(hppa_remove_hw_watchpoint): Make static.
	(macosx_can_use_hw_watchpoint): Take an int instead of an enum
	bptype (less correct, but it avoids a giant header-dependency
	headache, and besides, this stuff should be gdbarched anyway).
	* macosx-nat-watchpoint.h: New file.  Contains prototypes for
	functions in macosx-nat-watchpoint.c
	
2002-10-28  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-frameops.c (ppc_frame_saved_regs): Use signed long
	for the offset, not unsigned, to prevent bogus values on 64-bit
	BFDs.

2002-10-28  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-io.c (inferior_stat): New function.
	(inferior_bfd_generic): Pass inferior_stat as part of the inferior
	bfd function vector.

2002-10-26  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-tdep.c (ppc_frame_find_pc): Convert to use

	deprecated_read_register.

2002-10-24  Jason Molenda  (jmolenda@apple.com)

	* ppc-macosx-tdep.c (ppc_fast_show_stack): Stop counting frames
	at the limit, if a limit is given.

2002-10-23  Klee Dienes  <kdienes@apple.com>
	
	* i386-macosx-tdep.c (i386_macosx_sigcontext_addr): New function.
	(i386_macosx_init_abi): Set tdep->sigcontext_addr to
	i386_macosx_sigcontext_addr; set values for tdep->sc_pc_offset and
	tdep->sc_sp_offset.

2002-10-23  Klee Dienes  <kdienes@apple.com>
	
	* i386-macosx-nat-exec.c (store_inferior_registers): Disable the
	attempt to set the FP registers (until #3067308 is fixed).
	* macosx-nat-inferior-debug.c (macosx_debug_region): Use 0x%lx
	instead of 0x%ulx as a format string for unsigned long.
	* macosx-nat-inferior.c: Update debug levels passed to
	inferior_debug.
	* i386-macosx-tdep.c (i386_macosx_fetch_fp_registers): Handle SSE
	registers.
	(i386_macosx_store_fp_registers): Ditto.
	
2002-10-23  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-excthread.c (macosx_exception_thread): Include the
	exception data in exception thread debug output.

2002-10-22  Klee Dienes  <kdienes@apple.com>

	struct_return field to reg_struct_return.
	
2002-10-21  Klee Dienes  <kdienes@apple.com>

	* cached-symfile.h: New file.  Add prototypes for functions in
	* cached-symfile.c: Include cached-symfile.h.  Remove local
	declarations for exported functions.

	* macosx-nat-cfm.c (cfm_update): Convert to use
	cfm_fetch_context_containers instead of
	cfm_fetch_context_connections.
	(cfm_fetch_context_connections): Remove, and replace with
	cfm_fetch_context_containers.
	(cfm_parse_container_info): Also parse the 'next' field of the
	container.
	(cfm_fetch_connection_section_info): Remove, and replace with
	cfm_fetch_container_section_info.  No longer return the instance
	information; it's difficult to access since it is part of the
	connection structure, and it appears to be unused.
	* macosx-nat-cfm.h: Update prototypes.
	(NCFragContainerInfo): Add 'next' pointer.

	* macosx-nat-cfmthread.c (macosx_cfm_thread_init): Clear the
	breakpoint_offset and cfm_breakpoint fields.
	(macosx_cfm_thread_create): Store the cfm breakpoint in the thread
	status for future reference.
	(macosx_cfm-thread_destroy): Delete the cfm breakpoint, if present.
	* macosx-nat-cfmthread.h (macosx_cfm_thread_status): Add cfm_breakpoint.

	* macosx-nat-dyld-process.c (dyld_load_symfile): When generating
	the cfm parser, set cfm breakpoint offset to the last instruction
	of PrepareClosure.
	(dyld_libraries_similar): If both libraries provide a load address
	or offset, they compare similar only if the addresses or offsets
	are the same.  This allows for images to have multiple bundles
	with the same basename loaded simultaneously, yet still replace
	'cached' libraries with ones supplied by dyld.
	(dyld_libraries_compatible): Fix bug that would trigger a fatal
	assertion if (fres == lres == NULL), but fname and lname compared
	equal.
	(dyld_merge_shlib): New function.  Like dyld_merge_shlibs, but for
	a single library.  Fill in a dyld_objfile_entry 'n' with any
	objfile data from the dyld_objfile_info passed in as 'old'.
	Removes the objfile data from 'old' as it merges it into 'n'.
	(dyld_merge_shlibs): Update to use dyld_merge_shlib.
	(dyld_update_shlibs): No longer call dyld_merge_shlibs (it must
	now be called explicitly).
	* macosx-nat-dyld-process.h: Update prototypes.
	
	* macosx-nat-dyld-info.c (dyld_entry_info): Remove prototype.
	(dyld_reason_string): Add vlaues for dyld_reason_deallocated,
	dyld_reason_user, and dyld_reason_init.
	(dyld_objfile_entry_clear): Clear cfm_container instead of
	cfm_connection.
	(dyld_objfile_entry_compare): Compare cfm_container instead of
	cfm_connection.
	(dyld_entry_shlib_num): New function. Returns the shared library
	number of the entry at 'eptr' in 'numptr'.  Returns 0 on success,
	anything else on failure.
	(dyld_shlib_info_basename_length): New function.  Returns the
	length of the longest field that would be printed when displaying
	's' according to 'reason_mask'.  Code was previously in
	dyld_print_entry info.  Convert to use dyld_convert_entry.
	(dyld_entry_shlib_num_matches): New function.  Return true if and
	only if the shared library specifier 'shlibnum' matches the string
	in 'args'.  Returns 'false' on error; outputs warning messages
	only if 'verbose' is passed as true.
	(dyld_print_entry_info): New function.  Prints a
	dyld_obfile_entry, using 'shlibnum' as the shared library number
	and 'baselen' to determine the padding.
	(dyld_convert_entry): Fill a dyld_objfile_entry structure based on
	the contents of a struct objfile.
	(dyld_print_shlib_info): Convert to use
	dyld_shlib_info_basename_length, dyld_entry_shlib_num_matches,
	dyld_print_entry_info, and dyld_convert_entry.  Only output the
	table header if 'header' is specified as true.  Fix the table
	header to line up properly.
	* macosx-nat-dyld-info.h: Update prototyles.
	(enum dyld_objfile_reason): Add exclude
	'user' objects from dyld_reason_all_mask.
	(struct dyld_objfile_entry): Replace cfm_connection with
	cfm_container.
	
	* macosx-nat-dyld.c (_initialize_macosx_nat_dyld): Add new command
	"info sharedlibrary all", both for general use, and to allow "info
	sharedlibrary all 1-4 10".  It would be nice to have "info
	sharedlibrary" accept this same syntax, but since "info
	sharedlibrary" is a prefix command, that is a bit more
	challenging.
	(info_raw_cfm_comamnd, info_cfm_command, info_dyld_command,
	info_sharedlibrary_command): Replace with
	info_sharedlibrary_command, info_sharedlibrary_all_command,
	info_sharedlibrary_dyld_command, info_sharedlibrary_cfm_command,
	and info_sharedlibrary_raw_cfm_command. Update to use new
	interfaces to dyld_print_status_info and dyld_print_shlib_info.
	Only print 'status' information for info_sharedlibrary_command.
	(section_info_helper): Convert to use cfm_fetch_container_info
	instead of cfm_fetch_connection_info.
	(dyld_add_symbol_file_command): Call dyld_merge_shlibs explicitly;
	it's no longer called by dyld_update_shlibs.
	(dyld_remove_symbol_file_command): Ditto.
	(dyld_set_load_state_command): Ditto.
	(struct dyld_raw_info): New structure.  Used by dyld_info_read_raw
	to return raw dyld address information read from the target.
	(dyld_info_read): The dyld_info_read_raw function has been split
	into dyld_info_read_raw, dyld_info_process_raw, and
	dyld_info_read.  The dyld_info_read_raw function reads the raw
	information from dyld into a dyld_raw_info structure;
	dyld_info_process_raw processes the raw information into
	dyld_objfile_entries, and dyld_info_read adds the dyld
	pseudo-entry and uses dyld_info_read_raw and dyld_info_process_raw
	to implement the previous behavior of dyld_info_read_raw.
	(dyld_info_read_raw): See above.
	(dyld_info_process_raw): See above.  Update to read name
	information from the LC_ID entry of the library itself if no name
	information is provided by the caller (by specifying a 'name'
	argument of INVALID_ADDRESS)
	(dyld_print_status_info): Update to allow lists of libraires to be
	processed.  Remove check for 'uses_dyld' (it will now just print
	an empty list).
	(macosx_set_start_breakpoint): Also take a
	macosx_dyld_thread_status; update the dyld_breakpoint if it has
	not already been set.
	(FETCH_ARGUMENT): Ugly, and should be replaced, but stolen from
	the Objective-C code.  Returns the value at the n'th argument of
	the currently-executing stack frame.
	(macosx_add_shard_symbol_files): No longer check the value of
	uses_dyld.
	(macosx_dyld_update): Update to use dyld_info_read instead of
	dyld_info_read_raw.  Update to call dyld_merge_shlibs expliicitly.
	Add MI notification ("=shlibs-updated") that the shared library
	state needs to be fully refreshed.
	(macosx_solib_add): Properly return the value of libraries_changed
	to the calling code.  Add support to break at the DYLD event
	routine used by the old dyld_debug code, to detect individual
	shared library events.  Dispatch based on the location at which
	GDB has stopped in the inferior; if we have stopped at the event
	routine, do an incremental update where possible, otherwise revert
	to re-parsing the entire shared library state.  Add MI
	notification ("=shlibs-added") for the incremental-update case.
	* macosx-nat-dyld.h (macosx_dyld_thread_status): Convert unsigned
	ints to unsigned longs.  Add dyld_event_breakpoint.  Remove uses_dyld.
	(dyld_print_status_info): Update prototype.
	(macosx_set_start_breakpoint): Update prototype.
	(macosx_solib_add): Update prototype.

	* macosx-nat-mutils.c (macosx_thread_valid): Remove obsolete comment.

2002-10-17  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-inferior.c (macosx_child_attach): Use
	stop_soon_quietly/wait_for_inferior, not macosx_wait, to read the
	initial attach-events.  Otherwise the stop-status doesn't get
	correctly set, and we end up not printing the current stack frame
	in normal_stop after the attach.
	(macosx_child_attach): Print "Attaching to program" message
	when attaching.

2002-10-17  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (dyld_info_read_raw): Don't bother reading if
	status->dyld_addr hasn't yet been set.  Set prefix to
	dyld_symbols_prefix, not hardcoded to "__dyld_".  Set the name
	from status->dyld_name, not hard-coded to "/usr/lib/dyld" (this is
	set as the default if no dyld_name is provided).  Only set
	dyld_slide if status->dyld_slide has been set.  No longer call
	macosx_init_addresses; that's handled by macosx_dyld_init.  Don't
	bother checking for images if dyld_slide isn't set.  Improve
	sanity-checking and error-handling for bogus dyld data; no longer
	call error (instead, print a warning and stop processing
	libraries, returning any libraries already processed).
	(dyld_info_process_raw): Don't mess around with crazy bit-shifting
	tactics for the slide; just read it as a signed integer.
	(macosx_init_dyld): Only use o->obfd to set the bfd for the entry
	if 'o' is non-NULL.
	(macosx_dyld_thread_init): Initialize the dyld fields to
	NULL/INVALID_ADDRESS.
	(macosx_solib_add); Just call macosx_dyld_init to "do the right
	thing" to update the dyld state.
	(info_sharedlibrary_command): Update to use dyld_reason_all_mask.
	(macosx_init_addresses): Pass in a dyld_thread_status; don't use
	global.
	(lookup_dyld_value): Ditto.
	(lookup_dyld_address): Ditto.  Use the slide from the
	dyld_thread_status, not a global.
	(dyld_starts_here_p): Pass a correct value for the 'count' field
	into vm_region.  Reformat.
	(macosx_lookup_dyld_name): New function.  Tries to find the name
	string for the dynamic linker used by the bfd given as an
	argument.  Returns 1 if it found a name, 0 if it didn't, -1 if
	there was an error.
	(macosx_locate_dyld): New function.  Searches the target address
	space for dyld itself, returning it in 'value'.  Returns 1 if it
	found dyld, 0 if it didn't, -1 if there was an error.  If 'hint'
	is not INVALID_ADDRESS, check there first as a hint for where to
	find dyld.
	(macosx_locate_dyld_static): New function.  Determine the address
	where the current target expected DYLD to be loaded.  This is used
	when first guessing the address of dyld for symbol loading on
	dynamic executables, and also to compute the proper slide to be
	applied to values found in the dyld memory itself. Returns 1 if
	it found the address, 0 if it did not.
	(macosx_dyld_init): Update to use the new functions defined above.
	This function should now be able to be called at any time, and
	should always do as much of the right thing as possible based on
	the information available at the time.  See the comments in the
	function for more details.
		
	* macosx-nat-dyld-process.c (dyld_load_library): Use
	dyld_reason_executable_mask to account for an entry in state
	dyld_reason_cached_executable.
	(dyld_load_symfile): Ditto.
	(dyld_remove_objfile): Ditto.
	(dyld_remove_objfiles): Ditto.
	(dyld_merge_shlibs): Ditto.  Also, when marking an entry as
	'cached', use dyld_reason_cached_executable or
	dyld_reason_cached_library, as appropriate.
	(dyld_purge_cached_libries): Update to use
	dyld_reason_cached_mask, not dyld_reason_cached.
	
	* macosx-nat-dyld.h: Add new fields dyld_addr, dyld_slide, and
	dyld_name.  Update function declarations to match
	macosx-nat-dyld.c.

	* macosx-nat-inferior.c (macosx_child_create_inferior): Replace
	call to macosx_set_start_breakpoint with macosx_dyld_init.
	
	* ppc-macosx-tdep.h (INVALID_ADDRESS): Define as ((CORE_ADDR) -1),
	not 0xffffffff, for proper behavior when building 64-bit.

	* macosx-nat-dyld-info.h (dyld_objfile_reason): Split the 'cached'
	value into 'cached_library' and 'dyld_reason_cached_executable'.
	Replace the masks 'image', 'shlib', and 'all' with 'cached_mask',
	'executable_mask', 'image_mask', and 'all_mask'.

	* macosx-nat-dyld-info.c (dyld_reason_string): Add string values
	for dyld_reason_cached_library and dyld_reason_cached_executable.
	(dyld_print_shlib_info): Update output accomdate wider values for
	the 'reason' field.

2002-10-14  Klee Dienes  <kdienes@apple.com>

	* i386-macosx-thread-status.h (GDB_i386_FP_SSE2): Define.
	(GDB_i386_FP_387_STATE_SIZE): Define.
	(GDB_i386_FP_SSE2_STATE_SIZE): Define.
	(gdb_i386_thread_fpstate): Use GDB_i386_FP_SSE2_STATE_SIZE
	instead of hard-coding the value.

2002-10-13  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-frameinfo.c (ppc_frame_cache_boundaries): Use
	frame_address_in_block to choose the address to pass to
	ppc_find_function_boundaries.

2002-10-13  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-frameinfo.c: Remove local declarations for
	types/functions now provided by core GDB header files.  Convert
	functions to ANSI prototypes.  Convert calls from obstack_alloc to
	frame_obstack_alloc.
	(ppc_frame_cache_properties): Parse function properties directly
	into frame->extra_info->props, rather than storing in a local
	variable first.  Force the properties to set lr_saved to '1' for
	all non-leaf functions, regardless of what ppc_parse_instructions
	claims (previously it would only set it to ($pc - 8), when it was
	not set by ppc_parse_instructions).  This solved a problem where a
	function was calling a function declared 'volatile' and not
	expecting it to return, so the prev-frame $pc was past the end of
	the calling function and at the beginning of the next.
	ppc_parse_instructions was returning (correctly) that the function
	saved its $lr at ($pc + 8), and so the prev_saved_pc code was
	(incorrectly) deducing that the register had not been saved on the
	stack.  The real place to fix this problem is by calling
	ppc_parse_instructions on the correct address range ... but
	regardless, there's nothing that GDB can do if $lr isn't saved on
	a non-leaf, and so it's best for it to look in the $lr save-area
	in all situations.
	* ppc-macosx-frameops.h: Remove obsolete function declarations.
	* ppc-macosx-frameops.c: Remove local declarations for
	types/functions now provided by core GDB header files.  Convert
	functions to ANSI prototypes.
	(ppc_frame_saved_regs): Offset should be a CORE_ADDR, not a signed
	long.

2002-10-13  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-tdep.c Convert functions to ANSI prototypes.
	(ppc_null_fix_call_dummy): Remove.
	(gdb_register_names): Convert to const char *.
	
2002-10-13  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-tdep.h: Remove SKIP_TRAMPOLINE_CODE,
	DYNAMIC_TRAMPOLINE_NEXTPC, IN_SOLIB_DYNSYM_RESOLVE_CODE,
	IN_SOLIB_CALL_TRAMPOLINE, IN_SOLIB_RETURN_TRAMPOLINE,
	INIT_FRAME_PC_FIRST, INIT_FRAME_PC, and CONVERT_FROM_FUNC_PTR_ADDR
	(they will be moved to use gdbarch in macosx-nat-tdep.c).  Remove
	STACK_ALLOC.
	* ppc-macosx-tdep.c: Remove ppc_convert_from_func_ptr_addr,
	ppc_find_toc_address, and ppc_macosx_in_solib_dynsym_resolve_code.
	Use gdbarch to set init_frame_pc_first, skip_trampoline_code,
	dynamic_trampoline_nextpc, in_solib_call_trampoline,
	in_solib_return_trampoline, init_frame_pc_first, and
	init_frame_pc.
	* ppc-macosx-frameinfo.c (ppc_parse_instructions): Remove unused
	target_reg declaration (removes compiler warning).
	
2002-10-06  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-tdep.c (ppc_extract_return_value): Remove unused tdep
	pointer.  Convert to ANSI prototype.
	(_initialize_ppc_tdep): Add command for "info powerpc" (to match
	RS/6000 behavior).
	(ppc_breakpoint_from_pc): Now returned a const unsigned char *.

2002-10-05  Klee Dienes  <kdienes@apple.com>

	* i386-macosx-nat-exec.c (fetch_inferior_regsisters): Mark all
	SSE registers as NULL.  Add i386-tdep.h for IS_SSE_REGNUM ().
	* i386-macosx-tdep.c Include i386-tdep.h, i387-tdep.h, and osabi.h.
	(i386_macosx_fetch_fp_registers): Mark all FP registers as
	invalid, if declared so by the kernel.
	(sigtramp_saved_pc): Convert to ANSI-style declaration.
	(i386_macosx_init_abi): New function.  Update NUM_REGS to
	include the SSE registers.
	(i386_mach_o_osabi_sniffer): New function.  Return
	GDB_OSABI_MACOSX if debugging any Mach-O file.
	(_initialize_i386_macosx_tdep): New function.  Register
	i386_macosx_init_abi and i386_mach_o_osabi_sniffer.

2002-10-04  Klee Dienes <kdienes@apple.com>

	* ppc-macosx-regs.h: Remove 'registers' argument from fetch/set
	function prototypes.
	* i386-macosx-tdep.h: Remove IS_GSP_REGNUM, add IS_VP_REGNUM.
	Provide correct values for FIRST/LAST_*_REGNUM and NUM_*_REGS.
	Prototype i386_macosx_fetch/store_*_registers.
	* ppc-macosx-thread-status.h: Regularize names of function and
	macros to gdb_i386_thread_state/fpstate/vpstate.
	* i386-macosx-thread-status.h: Use the FLOAT_STATE instead of the
	THREAD_FPSTATE interface to fetch registers from the thread.
	Remove structures used for decoding floating-point information
	(the new interface provides a single buffer of raw data in FSAVE
	format).  Regularize names of function and macros to
	gdb_i386_thread_state/fpstate/vpstate.
	* ppc-macosx-regs.c (ppc_macosx_fetch/store_gp/fp/vp_registers):
	Re-implement using regcache_collect and supply_register.
	* i386-macosx-tdep.c: (ppc_macosx_fetch/store_gp/fp/vp_registers):
	Re-implement using regcache_collect, supply_register, and the new
	thread interface from i386-macosx-thread-status.h.
	* ppc-macosx-nat-exec.c: Include "regcache.h".
	(fetch_inferior_registers): Convert to new interface from
	ppc-macosx-tdep.h.  No longer set register_valid directly.
	(store_inferior_registers): Ditto.
	* i386-macosx-nat-exec.c: Include "regcache.h".
	(fetch_inferior_registers): Convert to new interface from
	i386-macosx-tdep.h.  No longer set register_valid directly.
	(store_inferior_registers): Ditto.
	* core-macho.c: Include the proper register definition header
	based on the target.  Convert to new register interface for both
	i386 and powerpc (we now use supply/collect_register instead of
	registers/register_valid).
	* remote-kdp.c: Properly conditionalize inclusion of
	"ppc-macosx-regs.h" and "i386-macosx-tdep.h".  Move inclusion
	before "defs.h" to avoid conflicting with the target.h definitions
	of PC_REGNUM and the like.  Fix compiler warnings.
	* macosx-nat-inferior.c: No longer check for tm_print_insn; it's
	not used by function any more (it used to be used for debugging
	output) (previous ChangeLog entry is spurious; change was
	mistakenly not committed previously).
	* macosx-metrowerks.c: No longer include ppc-macosx-tdep.h
	directly.

2002-10-02  Jason Molenda  (jmolenda@apple.com)

	* ppc-macosx-tdep.c (ppc_gdbarch_init): Don't say chars
	are unsigned.  This is causing some fails from the improperly
	written charset.exp test cases; there are precisely four
	targets that set char_signed to 0, and I can't come up with
	any benefit from being one of them.

2002-09-30  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-inferior.c: No longer check for tm_print_insn; it's
	not used by function any more (it used to be used for debugging
	output).

2002-09-27  Jason Molenda  (jmolenda@apple.com)

        * macosx-nat-inferior.c (macosx_pid_to_str): Revert last - adjusting
        the testsuite is the right way to go on this one.

2002-09-27  Jason Molenda  (jmolenda@apple.com)

        * macosx-nat-inferior.c (macosx_pid_to_str): Change text to match
        pthreads.exp's expectations.
        * macosx-nat-mutils.h (__MACH_CHECK_FUNCTION): Don't bother
        checking for gcc's older than 2.6.

2002-09-29  Klee Dienes  <kdienes@apple.com>

	* cached-symfile.c (build_objfile_section_table): Properly
	Terminate objfiles->sections_end even if there are no sections in
	the objfile.  * core-macho.c (check_thread): Use a process-id of 1
	for the core threads; store (1, logical thread number, bfd section
	number) as
	(pid, lwp, tid).  This allows proper output of thread numbers when
	displaying threads, and avoids a previous bug where a thread
	stored as the first load command in a core file would be confused
	with null_ptid (since both tuples are 0, 0, 0).
	(macosx_core_ptid_to_str): Output correct thread IDs, not "??".  :
	Use the new macros for ptid access instead of PITGET/TIDGET.
	
2002-09-28  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.h (macosx_dyld_thread_init): Add.
	(macosx_dyld_thread_status): Add dyld_breakpoint field.
	* macosx-nat-dyld.c (macosx_dyld_thread_init): Add.
	(macosx_set_start_breakpoint): Only set the breakpoint if it
	hasn't already been created.
	(macosx_solib_add): Don't call macosx_remove_start_breakpoint ---
	this breaks stop-on-solib, since macosx_solib_add gets called from
	the stop-on-solib breakpoint, and ends up trashing the stop_bpstat
	when it removes and re-adds the breakpoint.  Instead, rely on
	macosx_set_start_breakpoint to only set the breakpoint if it
	hasn't been created yet.
	* macosx-nat-inferior-util.c (macosx_inferior_reset): Call
	macosx_dyld_thread_init.

2002-09-28  Klee Dienes  <kdienes@apple.com>

	* ppc-macosx-tdep.c (ppc_store_return_value): Convert floats to
	doubles before storing in registers.  Store shorts and chars in
	the proper end of registers on big-endian machines.

2002-09-27  Jason Molenda  (jmolenda@apple.com)

	* macosx-nat-inferior.c (macosx_pid_to_str): Revert last - adjusting
	the testsuite is the right way to go on this one.

2002-09-27  Jason Molenda  (jmolenda@apple.com)

	* macosx-nat-inferior.c (macosx_pid_to_str): Change text to match
	pthreads.exp's expectations.
	* macosx-nat-mutils.h (__MACH_CHECK_FUNCTION): Don't bother
	checking for gcc's older than 2.6.

2002-09-26  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-mutils.h (__MACH_CHECK_FUNCTION): Update to account
	for gcc3.

2002-09-24  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld.c (macosx_locate_dyld): Don't check for the
	Mach-O structures for non- Mach-O files.

2002-09-24  Klee Dienes  <kdienes@apple.com>

	See comments in the top-level ChangeLog.
	
	* macosx-nat-dyld.c (lookup_dyld_address): Return -1 on error,
	instead of throwing an error.
	* (lookup_dyld_address): Propagate -1 from lookup_dyld_address.
	* (macosx_locate_dyld): No longer called from SOLIB_ADD; update comment.
	* (macosx_locate_dyld): Warn, rather than error, when unable to find address
	of dylinker.
	* (macosx_set_start_breakpoint): Just set the breakpoint; don't
	try to locate dyld or init addresses.
	* (macosx_solib_add): Replaces macosx_try_start_dyld.  Inits
	addresses, sets start breakpoint, does section table updates.
	Designed to be able to be called repeatedly and "do the right
	thing" whenever.
	* (macosx_init_dyld): Update to take exec_bfd as an argument.  If
	exec_bfd does not match the bfd for the current symfile, use it in
	preference.
	* (update_section_tables): Move from objfile.c.  Re-implement to
	base section tables off of a dyld_objfile_info, not the list of
	objfiles (which is more correctly a list of symbols loaded, not
	executables).
	* macosx-nat-dyld.h (update_section_tables): Add prototype.
	* (macosx_init_dyld_symfile): Add exec_bfd as argument.
	* macosx-nat-inferior.c (macosx_set_auto_start_dyld): Use macosx_solib_add.
	* (macosx_child_attach): Ditto.
	
2002-09-23  Jim Ingham (jingham@apple.com)

	* ppc-macosx-tdep.c (ppc_find_function_boundaries): Use refine_prologue_limit so
	if there is line number information, we get its benefit in trying to skip the 
	prologue.
	
2002-09-20  Jason Molenda  (jmolenda@apple.com)

	* ppc-macosx-tdep.c (ppc_gdbarch_init):  Set pop_frame to
	rs6000_pop_frame, not generic_pop_dummy_frame.  Set ppc_lr_regnum -
	rs600-tdep.c uses this way of storing these register numbers
	and rs6000_pop_frame needs to know the $lr regnum.

2002-08-27  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-frameops.c: Delete all but ppc_frame_cache_saved_regs
	and ppc_frame_saved_regs.  We now use the rs6000 code for pushing
	function arguments.

	* ppc-macosx-tdep.c: Remove gdbarch_tdep; we now use the one from
	"ppc-tdep.h".

	* ppc-macos-tdep.c: Update to use the rs6000 and generic call-dummy support.
	(ppc_push_return_address): Store the new return address in the LR
	and in the saved LR location in the linkage area.
	(ppc_call_dummy_words): Remove.	
	(ppc_frame_find_pc): Update to use generic call_dummy support.
	(rs6000_push_arguments): Add local prototype.
	(ppc_gdbarch_init): Update to use the rs6000 and generic call-dummy support.
	
	* macosx-nat-inferior.c (macosx_child_create_inferior): Make sure
	exec_bfd isn't NULL before checking to see if it is a PEF binary.

	* ppc-macosx-frameops.c (ppc_push_dummy_frame): Delete.
	
2002-08-20  Jim Ingham   <jingham@apple.com>
 
 	* macosx-tdep.c (macosx_symbol_type): If the section is not the
 	first section, see if it is in the TEXT segment to determine
 	whether to label it TEXT or DATA...
 	
2002-08-06  Klee Dienes  <kdienes@bluegill.localnet>

	* (macosx-nat-watchpoint.c): Rename
	target_range_profitable_for_hw_watchpoint to
	target_range_ok_for_hw_watchpoint.

2002-08-06  Klee Dienes  <kdienes@bluegill.localnet>
	 
        * macosx-nat-inferior.c (macosx_handle_exception): macosx_status
        is already a pointer; pass it to macosx_inferior_resume_mach, not
        its address.

        * macosx-nat-inferior-util.c (macosx_inferior_resume_ptrace): Pass
	the signal to ptrace whever the inferior is either (a) detaching,
	or (b) not stopped by a software exception.
	
2002-08-06  Klee Dienes  <kdienes@bluegill.localnet>

        * ppc-macosx-tdep.c: Made the maximum stack frame size
        configurable via 'ppp-maximum-frame-size', and set the default to
        'unlimited'.  It's tempting to have ppc-maximum-frame-size default
        to 512K, since that's the default stack allocation size on Mac OS
        X.  But I couldn't think of a compelling reason to do it, and
        UINT_MAX is much less dependent on OS-level changes.

2002-07-19  Jim Ingham   <jingham@apple.com>

	* macosx-nat-inferior.c (macosx_child_create_inferior): Don't let someone
	try to run a CFM binary, error out here instead.
	
2002-07-12  Jim Ingham   <jingham@apple.com>

	* tm-ppc-macosx.h: Change FAST_SHOW_STACK macro to take a 
	print function.
	* ppc-macosx-tdep.c: Remove the ppc_fast_show_stack command,
	only the MI version is really interesting.  ppc_fast_show_stack_helper
	becomes ppc_fast_show_stack, and now takes the print_fun argument.
	
2002-07-09  Jim Ingham   <jingham@apple.com>

	* machoread.c (macho_symfile_offsets): don't cast a CORE_ADDR
	as a long, that's no way to truncate it...
	* macosx-nat-dyld.c (dyld_info_process_raw): Handle the case
	where a CORE_ADDR is bigger than the native address size, and
	the dyld slide causes the load address to wrap around.

2002-06-27  Jim Ingham <jingham@apple.com>

	* macosx-nat-inferior-util.c (macosx_inferior_reset): Set uses_dyld
	to 1.  If we are wrong about this, it is only a problem when we go
	to set the start breakpoint, and we always check before we do that,
	so this is a better setting.
	* macosx-nat-dyld.c (macosx_locate_dyld): exec_bfd is NULL currently
	when you attach.  (FIXME - why is this the case?).  So only change
	uses_dyld if you really have an exec_bfd to look at.
	
2002-06-26  Klee Dienes  <kdienes@annecy.apple.com>

	* ppc-macosx-frameinfo.c (ppc_parse_instructions): properly
	initialize 'start'.

2002-06-17  Klee Dienes  <kdienes@bluegill.localnet>

	* macosx-nat-inferior-util.c, macosx-nat-inferior.c: move the
	signal to the exception thread that causes it to continue out of
	individual functions, and into macosx_inferior_resume_mach.  Add
	calls to sched_yield() after killing the target and before
	terminating the debug thread, so that the debug thread has a
	chance to reap the dead target in waitpid().

2002-06-17  Klee Dienes  <kdienes@bluegill.localnet>

	* macosx-nat-inferior-util.c (macosx_inferior_resume_ptrace):
	check for PTRACE_DETACH, and always call ptrace in that case.

2002-06-17  Klee Dienes  <kdienes@law.apple.com>

        * macosx-nat-mutils.c (mach_xfer_memory): Handle integer overflow
	when returning negative values.  Previously when the next
	available address was more -INT_MIN away from the address
	requested, mach_xfer_memory would overflow and return a positive
	number in error.  Now it just returns 0.  A better fix for this
	would be to change the signature for mach_xfer_memory, but that's
	a much bigger change.

2002-06-13  Jim Ingham <jingham@apple.com>

        * ppc-macosx-regs.c: New function ppc_macosx_stab_reg_to_regnum,
        this implements the mapping from the gcc3 stabs register numbering
        scheme to gdb's internal numbering scheme.
        * ppc-macosx-regs.h: Declare it.
        * ppc-macosx-tdep.c: Add ppc_macosx_stab_reg_to_regnum to the ppc
        gdbarch.
        
2002-06-12  Klee Dienes  <kdienes@law.apple.com>

	* macosx-nat.c: remove obsolete (#ifdef 0) exception processing code.

2002-06-07  Jim Ingham <jingham@apple.com>

	* macosx-nat-dyld.c (macosx_locate_dyld): If we notice that the
	exec_bfd doesn't have the DYLINKER load command, then note that
	that fact in the dyld_status.
	(dyld_print_status_info): don't try to print dyld info if dyld isn't
	used.
	(macosx_set_start_breakpoint): don't try to set the start breakpoint
	if the executable doesn't load dyld.
	(macosx_add_shared_symbol_files): don't try to do this if the executable
	doesn't load dyld either.
	* macosx-nat-dyld.h: add uses_dyld to the dyld_status structure.

	* macosx-tdep.c (dyld_symbol_stub_function_addr): check that the block
	for the symbol value we just found is valid before trying to access it.

	* ppc-macosx-frameinfo.c (ppc_parse_instructions): treat an "sc" or a
	bare branch (except for the ones we recognize)  as end of prologue
	markers.  This way we don't scan too far in some hand-crafted functions,
	"read" being the example I found.
	
2002-05-30  Rab Hagy <rhagy@apple.com>

	* ppc-macosx-tdep.c, tm-ppc-macosx.h: added a limit argument to 
	ppc_fast_show_stack_helper.

2002-05-24  Klee Dienes  <kdienes@bluegill.localnet>

	* cached-symfile.c: Improve logic to detect mismatch between
	cached symbol files and object file / GDB versions.

2002-05-24  Klee Dienes  <kdienes@bluegill.localnet>

	* cached-symfile.c (open_mapped_objfile): Use openp instead of
	explicit search logic to find the cached symbol file; respect the
	'cached-symfile-path' variable.
	(_initialize_cached_symfile): Add cached-symfile-path variable.
	(dyld_cache_symfiles): Cleanup.

2002-05-23  Jim Ingham <jingham@apple.com>

	* machoread.c (macho_read_indirect_symbols): New function, 
	encapsulate getting the "dyld_stub" symbols from a SYMBOL_STUB
	type section.
	(macho_symfile_read): read in both the __picsymbol_stub and the
	new __symbol_stub sections.
	
2002-05-14  Jim Ingham <jingham@apple.com>

	* ppc-macosx-frameinfo.c (ppc_parse_instructions): Keep
	track of the last recognized instruction so we don't over
	report the prologue's size.
	
2002-05-01  Klee Dienes  <kdienes@bluegill.localnet>

	* config/i386/macosx.mh, config/i386/nm-i386-macosx.h,
	config/i386/tm-i386-macosx.h, macosx/i386-macosx-nat-exec.c,
	macosx/i386-macosx-tdep.c, macosx/macosx-nat-inferior.c:
	Fixes for i386.

2002-05-01  Klee Dienes  <kdienes@bluegill.localnet>

	* ppc-macosx-regs.h: re-order register numbering. VSCR is a 4-byte
	integer.

	* ppc-macosx-tdep.c (gdb_register_names): update to new ordering.

	* ppc-macosx-tdep.c (ppc_register_virtual_type): Change type of
	AltiVec registers to builtin_type_vec128.

	* ppc-macosx-regs.c (ppc_macosx_skip_trampoline_code,
	ppc_macosx_dynamic_trampoline_nextpc,
	ppc_macosx_in_solib_dynsym_resolve_code,
	ppc_macosx_in_solib_return_trampoline): move to ppc-macosx-tdep.c.

	
2002-05-01  Klee Dienes  <kdienes@bluegill.localnet>

	* ppc-macosx-frameinfo.c (ppc_parse_instructions): gcc3 has a new
	instruction 'mr r31,r12' in a function prologue.  Ignore it.

2002-04-23  Klee Dienes  <kdienes@bluegill.localnet>

	* ppc-macosx-regs.c (ppc_macosx_fetch_vp_registers) Process the
	vector data as unsigned integer, not as float (the Mach interface
	returns them as unsigned int as well).
	(ppc_macosx_store_vp_registers): Ditto.

2002-04-15  Jim Ingham  <jingham@apple.com>

	* core-macho.c: Small cleanups to remove compiler warnings.
	* macosx-metrowerks.c: ditto.
	* nextstep-core.c: ditto.
	* nextstep-nat-cfm.c: ditto.
	* nextstep-nat-cfmthread.c: ditto.
	* nextstep-nat-dyld-info.c: ditto.
	* nextstep-nat-dyld-io.c: ditto.
	* nextstep-nat-dyld-path.c: ditto.
	* nextstep-nat-dyld-process.c: ditto.
	* nextstep-nat-dyld-process.h: ditto.
	* nextstep-nat-dyld.c: ditto.
	* nextstep-nat-excthread.c: ditto.
	* nextstep-nat-inferior-debug.c: ditto.
	* nextstep-nat-inferior-debug.h: ditto.
	* nextstep-nat-inferior-util.c: ditto.

	* nextstep-nat-inferior.h: ditto.
	* nextstep-nat-info.c: ditto.
	* nextstep-nat-mutils.c: ditto.
	* nextstep-nat-sigthread.c: ditto.
	* nextstep-nat-threads.c: ditto.
	* nextstep-nat-watchpoint.c: ditto.
	* ppc-frameinfo.c: ditto.
	* ppc-frameops.c: ditto.
	* ppc-next-tdep.h: ditto.
	* ppc-tdep.h: ditto.
	
2002-04-11  Jim Ingham	<jingham@apple.com>

	* nextstep-nat-dyld.c (dyld_lookup_and_bind_function): New function
	calls NSLookupAndBindSymbol on a function to make sure the module
	is bound before we try to call a function.
	* nextstep-nat-dyld.h: declare dyld_lookup_and_bind_function.
	* nextstep-nat-inferior.c (_initialize_next_inferior): Add 
	dyld_lookup_and_bind_function to the child_ops.
	
2002-03-26  Jim Ingham  <jingham@apple.com>

	* macosx-nat-dyld.c: (macosx_locate_dyld): New function, extract
	this functionality from macosx_set_start_breakpoint.
	Also, don't pass a null cleanup to do_cleanups.
	(dyld_starts_here_p): New function, again, refactoring for
	convenience.

2002-03-19  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-process.c: rearrange the include order to remove a few
	compiler warnings.
	
	* ppc-tdep.c (ppc_fast_show_stack_helper): Return 1 when you find
	only 1 frame, not 0 dummy...

	* ppc-frameinfo.c (ppc_parse_instructions): Fix a bug with handling the
	saveFP builtin function in prologues.

2002-03-19  Klee Dienes  <klee@apple.com>

	* macosx-nat-inferior.c: Check incoming exceptions --- if the
	task receiving the exception is not the same as the one being
	debugged by GDB, reset the exception ports of the task back to the
	ones GDB saved for the target when it first started debugging;
	then resume the task.  This isn't quite perfect, since ideally GDB
	would allow changes to the exception ports made by the target be
	reflected in children of the target as well; and also because it
	relies on being able to repeat an exception by simply continuing
	the child without modifying the program state (I think this should
	always work, but there may be cases I haven't thought of).

2002-03-19  Klee Dienes  <klee@apple.com>

	* macosx-nat-dyld.c (dyld_info_process_raw); Treat ':' as a
	string terminator when reading library names from DYLD.

2002-03-14  James Ingham  <jingham@inghji.apple.com>

	* ppc-tdep.c (ppc_fast_show_stack_helper): Use lookup_minimal_symbol to find
	_sigtramp, it is much more efficient than parse_and_eval_address...

2002-03-05  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld.c (dyld_starts_here_p): New function, does the memory
	passed in actually contain dyld?
	(macosx_locate_dyld): New function, find where dyld got loaded in this
	executable.
	(macosx_set_start_breakpoint): call macosx_locate_dyld.
	(dyld_lookup_address): use the slide set by macosx_locate_dyld.

	* macosx-nat-cfm.h: add cfm_update to silence compiler warnings.
	* macosx-nat-dyld-info.h: add dyld_objfile_info_compare.
	* macosx-nat-dyld-process.h: add dyld_parse_load_level and
	dyld_minimal_load_flag.
	* macosx-nat-dyld.h: remove macosx_start_dyld - it is never used
	or defined.

2002-02-26  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-sigthread.c (macosx_signal_thread): Don't call pause
	in between pthread_testcancel calls, we never get a signal to wake
	us up...
	
	* macosx-nat-inferior.c (macosx_clear_pending_events): New
	function, clears out the pending event chain.
	(macosx_mourn_inferior): Call macosx_clear_pending_events.

2002-02-21  James Ingham  <jingham@inghji.apple.com>

	* remote-kdp.c (kdp_resume): Fix signature of kdp_resume - should
	be a ptid_t for first argument, not an int...

2002-02-06  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-process.c (dyld_libraries_compatible): The prefix may 
	be NULL, check this before comparing the contents.
	(dyld_objfile_move_load_data): copy the prefix over as well.
	* macosx-nat-dyld-info.c (dyld_objfile_entry_clear): The unset value for
	the prefix should be NULL, not "".

2002-01-25  James Ingham <jingham@inghji.apple.com>
        Create a queue of "pending events" to handle the case where we get more
	than one event from either Mach or BSD when the inferior stops.  If we
	get more than one event, then we report them to the user serially, and
	each call to macosx_child_resume will fetch the next pending event till
	the queue is exhausted.  Only then do we really resume the inferior.
	
	* macosx-nat-inferior-stubs.c: Fix child_wait to pass the client_data
	field.
	* macosx-nat-inferior-util.c (macosx_inferior_suspend_ptrace): Fix call 
	to macosx_wait.
	* macosx-nat-inferior.h: Change declaration of macosx_wait.
	* macosx-nat-inferior.c: Include regcache.h to remove compiler warnings.
	Generalize the signal & exception handling functions so we can share them 
	between the immediate event handling and the deferred servicing routines.
	Add the macosx_pending_event struct, queue, and handling functions.
	* kdp.c: change declaration of kdp_wait, and since the gdb_queue_event
	function is now exported, remove the copy of it from here.
	
2002-01-18  James Ingham  <jingham@inghji.apple.com>

	* i386-macosx-nat-exec.c (fetch_inferior_registers): Fix a reference to
	the obsolete inferior_pid.
	(store_inferior_registers): ditto

2002-01-11  James Ingham  <jingham@inghji.apple.com>

	* ppc-tdep.c (ppc_breakpoint_from_pc): Fixed a couple of places
	where we needed to switch BIG_ENDIAN for BFD_BIG_ENDIAN.

2001-12-07  James Ingham  <jingham@inghji.apple.com>

	(From Bernard Semeria)
	* remote-kdp.c (kdp_attach): Use the version packet rather than
	hijacking the region packet to get the kdp version.
	* kdp-protocol.c (kdp_marshall, kdp_unmarshall): ditto.
	* kdp-protocol.h: ditto.

2001-12-03  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-inferior.c: Format changes, more functions comply
	with the GNU coding conventions.  Also added a few prototypes, and
	extern'ed some functions from exec.c to remove compiler warnings.

	* macosx-nat-inferior.c (macosx_set_auto_start_dyld): New
	function, used to dynamically switch the dyld breakpoint on and
	off.
	(_initialize_macosx_inferior): use macosx_set_auto_start_dyld.
	
	(macosx_process_events): drain both event sources here, not just the
	one you got the first hit on.  We have more chance of handling
	extraneous events here than in macosx_child_resume...
	
2001-11-01  James Ingham  <jingham@inghji.apple.com>

	* ppc-tdep.c (ppc_fast_show_stack_helper): Move most of the
	functionality into this function, and set it as the
	FAST_COUNT_STACK_DEPTH function, which is used in
	mi_cmd_info_stack_depth.
	* tm-ppc.h: Add define for FAST_COUNT_STACK_DEPTH
	
2001-10-31  James Ingham  <jingham@inghji.apple.com>

	* ppc-tdep.c (ppc_fast_show_stack): New function.  Run up the
	stack and return pc & fp for each frame, and a frame count.  Since
	this doesn't build up the frame cache, it is much faster.
	(ppc_frame_find_pc): We were looking in the wrong place for the
	frame stored PC for signal frames.

2001-10-30  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-process.c (dyld_add_image_libraries): 
	recognize BFD_MACH_O_LC_LOAD_WEAK_DYLIB; treat it like
	LC_LOAD_DYLIB for now.

2001-10-26  Klee Dienes  <kdienes@apple.com>

	* macosx-nat-dyld-info.c (dyld_entry_out): Send the basename as
	the "path" field when talking via MI.  The ProjectBuilder shared
	library dialog uses the pathname as the key for the table, so all
	entries without a "path" field were getting collapsed into one
	line in the table.  The correct fix for this is to have PB used a
	different algorithm for building the table, but this fix should
	work well for now.

	* macosx-nat-dyld-process.c (dyld_load_library): Automatically
	load CFM fragments from memory, rather than trying to load from
	disk first.  The only time we should be relying on the fragment
	name to match a disk file is when looking for xSym files.  Trying
	to read from disk was taking extra time in the cases where the
	disk access failed, and the warning messages when it failed were
	distracting.

	* macosx-nat-dyld-.c (inferior_bfd_generic): Handle the case
	where a memory object is provided without a text string for the
	name (previously it would crash).

2001-10-23  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld.c (macosx_dyld_update): If you have turned off
	cfm with the inferior-auto-start-cfm variable, then don't call
	update-cfm when you update the libraries.

2001-10-17  James Ingham  <jingham@inghji.apple.com>

	* ppc-tdep.c (ppc_frame_find_pc): Actually return the signal frame
	value. Dopey bug...
	(ppc_frame_saved_pc_after_call): remove spurious warning.  This is
	always supposed to return the link register, and looking for the
	frame saved value is not relevant.
	(ppc_frame_chain_valid): Guard the call that reads the stack from
	errors.  Callers don't expect ppc_frame_chain_valid to error out,
	but it can if the stack is mauled so that the fp is an unreadable
	address.

	* ppc-frameinfo.h: define safe_read_memory_unsigned_integer, so
	that ppc-tdep can use is.  
	
	* ppc-frameinfo.c (ppc_parse_instructions): Don't assume that the
	pic base will use register 31.  The dyld stub code uses 11, for
	instance.

2001-10-02  Jim Ingham (jingham@apple.com) and Jason Molenda (jmolenda@apple.com)

       * macosx-nat-inferior.c (macosx_fetch_event):  Accept a third
       type of timeout:  Check for an event to read, but don't block if
       there's nothing there.
       (macosx_process_events, macosx_child_resume):  Update callers.

2001-08-06  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (safe_read_memory_unsigned_integer): The wrapped
	function has to return a value, or bad things happen...
	(ppc_frame_cache_properties): pass the function_end as the stop
	for the parsing, not the pc.  This way we can correctly parse the
	prologue & figure out where we are EVEN IF the pc is in the
	prologue.

2001-08-03  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-info.c (dyld_entry_info): Check for 
	e->loaded_name not null before passing to strrchr.

2001-08-02  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld.c (_initialize_macosx_nat_dyld): fix up doc strings.
	(macosx_init_dyld): Add a missing check for the ofile being NULL.

2001-08-02  Derek Kumar

	* remote-kdp.c: Added breakpoint packets, kdp-reattach and
	versioning support and kdp_mourn_inferior()

2001-07-31  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-process.c: The dyld code doesn't own the
	objfile for the executable.  The generic gdb code keeps a pointer
	to this through the symfile_objfile pointer.  So let the generic
	code handle the lifetime of the executable objfile.

2001-07-27  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (safe_read_memory_unsigned_integer): New
	function, safe version of read_memory_unsigned_int.
	(wrap_read_memory_unsigned_integer): This is the wrapper function.
	(ppc_parse_instructions): catch errors from
	read_memory_unsigned_integer, this gives us a much better chance
	of cleaning up from cases where the pc is off in unreadable
	memory.

2001-06-21  Klee Dienes  <kdienes@localhost>

	* macosx-nat-dyld.c (section_info_helper): protect the CFM
	section of the code with #if WITH_CFM .

2001-06-14  James Ingham  <jingham@gdbrulez.apple.com>

        * ppc-frameinfo.c (ppc_parse_instructions): properly sign extend
	the instruction offset from the "bl" instruction - the old way
	didn't work for CORE_ADDR = unsigned long long.
	
	* macosx-nat-dyld-path.c (dyld_resolve_image): check for name
	being null and don't crash.
	* macosx-nat-dyld-process.c (dyld_resolve_load_flag): Ditto...

2001-06-07  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (ppc_frame_cache_properties): protect against
	the case where we think the lr wasn't saved in a non-leaf
	function.
	* ppc-tdep.c (ppc_frame_find_pc): ditto.

2001-05-18  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (ppc_parse_instructions): Add a fallback if we
	don't recognize ANY valid prologue instructions.  In that case, we
	are just guessing, but guess that the pc is stored on the stack,
	since this is usually the case.

2001-05-15  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-info.c (dyld_print_shlib_info): use dyld_entry_out to 
	output the path, offset & slide in ui-out'ified form.
	(dyld_entry_string): Use dyld_entry_info.
	(dyld_entry_out): New function, format the path, offset & slide in ui-out.
	(dyld_entry_info): Generic function, returns path, offset & slide in separate
	fields, for use in dyld_entry_string & dyld_entry_out.

2001-05-10  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld.c (dyld_print_status_info): ui_out'ify the info 
	messages so we don't spam the mi...

	* macosx-nat-dyld-info.c (dyld_print_shlib_info): ui_out'ify the
	output from info sharedlibrary.

2001-04-18  Jim Ingham  <jingham@localhost.apple.com>

	* ppc-tdep.c (ppc_get_unsaved_pc): New function.  How to get the
	frame's pc if it hasn't been saved in the frame.
	(ppc_frame_find_pc): Reworked the logic to better handle cases
	where the of the parent frame is in its prologue.
	(ppc_frame_chain_valid): If the frame pointer is null, we are at
	the end of the stack.  Re-enable the code that does this check.
	Klee thinks this might cause trouble somewhere but can't remember
	where, and it is the right thing to do, so...

	* ppc-frameinfo.h: Removed the offset2 field, it was just for use
	IN ppc_parse_instructions.  Added lr_invalid to handle prologues
	that temporarily invalidate the link register.

	* ppc-frameinfo.c (ppc_print_properties): mutatis mutandi for
	changes to the properties structure.
	(ppc_parse_instructions): Add support for the saveFP and saveVec
	gcc prolog setup routines.  Also record WHEN the link register is
	stored in the frame so we can do a better job of backtraces while
	in the prolog.
	(ppc_clear_function_properties): mutatis mutandi for changes to
	the properties structure.

2001-02-21  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-process.c (dyld_load_library): If you get an
	error in getting the TEXT segment for a shlib, mark the entry as
	invalid.  You can't free it, it wasn't malloc'ed...

2001-01-24  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-inferior.c (macosx_fetch_task_info): Comment out the call 
	to macosx_init_dyld_symfile.  This caused gdb to reset shared library
	info when quitting.
	(macosx_child_stop): New function: don't use child_stop, it sends
	a kill (-pid, SIGINT) which doesn't work on MacOS X unless the inferior
	actually IS a process group leader.  But apps in MacOS X almost never
	are (they are children of the WindowServer).
	
	initialize remote_async_terminal_ours_p to 1 - this reflects truth:
	gdb at startup DOES own the terminal.
	* remote-kdp.c: ditto.

2001-01-22  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (ppc_frame_cache_properties): Check that the
	frame's extra_info is set.

2000-11-07  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (ppc_parse_instructions): If the FIRST instruction of the
	prologue is a bl, we are probably NOT in the prologue.

	* ppc-tdep.c (ppc_frame_find_pc): In the case where we have no symbols, 
	use the instruction parser to tell us whether the return address has
	been put on the stack yet or not.

2000-09-06  Jim Ingham  <jingham@localhost>

	* macosx-nat-inferior-util.c: add WITH_CFM guards in the
	appropriate places.
	* macosx-nat-inferior.c: ditto
	* macosx-nat-inferior.h: ditto.

2000-09-05  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.c (ppc_parse_instructions): Cleanup a comment & remove
	an unused variable.

2000-09-01  James Ingham  <jingham@inghji.apple.com>

	* ppc-frameinfo.h: Added a few comments.

	* ppc-frameinfo.c (ppc_parse_instructions): Detect the
	"save_world" stack setup routine that gcc uses for C++, and set up
	the props structure based on what it does.  NB. This will break if
	gcc changes this routine, but there's not much I can do about
	this...

2000-08-09  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-dyld-path.c (build_suffix_name): new function, find
	full name including the DYLD_IMAGE_SUFFIX.
	(search_for_name_in_path): Pass in the
	suffix that comes from DYLD_IMAGE_SUFFIX, and use in search.
	(get_framework_pathname): pass in flag telling whether to use
	the image suffix, and use it.
	(dyld_resolve_image): use the image suffix in resolving the image 
	path.
	(dyld_init_paths): Initialize the image_suffix from the environment.
	* macosx-nat-dyld-path.c: Add image_suffix to dyld_path_info struct.

2000-07-20  James Ingham  <jingham@inghji.apple.com>

	* macosx-nat-inferior-debug.c: Add fflush to the inferior_stderr.  
	There may be other places where this is needed as well, but we 
	will chase them down as we find them.

	* macosx-nat-inferior.c: Open the inferior_stderr "w", not
