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

Convert the entire file to the new bfd iovec semantics. Convert

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

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.
2004-11-30 Jason Molenda (jmolenda@apple.com)
* macosx-nat-dyld.c (dyld_info_process_raw): Change ppc64 file handling
to work better.

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_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.

well as all the get_frame_base (prev_frame) gunk ... this is now

to be an offset, not an absolute value. Set the 'objfile' field
of the relocation struct when relocating the objfile; don't set
the objfile field explicitly. Allocate a fresh malloc()-based

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

2003-04-17 Jim Ingham (jingham@apple.com)
* machoread.c (macho_read_indirect_symbols): Don't hard-code the
names of sections containing symbol stubs, instead scan all the

This set of changes are the Mac OS X side of the changes to only
set breakpoints in newly added objfiles, and not reset them once
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
code where it properly belongs.
* macosx-nat-dyld.c (macosx_solib_add): Don't update the catchpoints
here. Marking the solib as changed will trigger it in generic code.

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.

native bits still don't obey this but at least the upper layers
will.

ignore fix-and-continue NOP prologue padding.
* cached-symfile.c (allocate_objfile): Don't create "syms" directory
turds when I'm running gdb. Waiting for fix of r. 3204584.

* 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

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
next_allocated, moved from macosx-nat-dyld-process.c.
* macosx-nat-dyld-info.h (dyld_next_allocated_shlib): Add
prototype.
(DYLD_ALL_OBJFILE_INFO_ENTRIES): Moved from
macosx-nat-dyld-process.c.
* macosx-nat-dyld-process.c (DYLD_ALL_OBJFILE_INFO_ENTRIES): Moved
to macosx-nat-dyld-info.h
(next_allocated): Moved to macosx-nat-dyld-info.h
* macosx-nat-inferior.c (macosx_mourn_inferior): Replace
hand-written code in the #if 0 with a call to
macosx_init_dyld_symfile.
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>
* macosx-nat-dyld-process.c (dyld_add_image_libraries): Add
handler for LC_LOAD_WEAK_DYLIB.
2002-11-01 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_remove_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
frame_unwind_unsigned_register instead of
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>
* i386-macosx-tdep.c (i386_macosx_init_abi): Set the target
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_detach): Print "Detaching from
program" message when detaching.
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.

* 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
"w+", so the debugging output will work when gdb is running as
pipe under another program.
2000-06-23 James Ingham <jingham@inghji.apple.com>
* macosx-nat-dyld-process.c: Take out the call to
build_objfile_section_table, since it only screwed up the
section table, and had no other purpose...
