(update_section_tables_dyld): Little cleanup. 2004-12-16 Jason Molenda (jmolenda@apple.com) * macosx-nat-dyld-info.h: Comment add. 2004-12-16 Jason Molenda (jmolenda@apple.com) * macosx-nat-dyld.c: Comment tweak. * macosx-nat-dyld-process.c: Code rearrangement.

A little reformatting and such. * macosx-nat-dyld-info.h: Comment fix. 2004-12-03 Jason Molenda (jmolenda@apple.com) * macosx-nat-dyld-path.c (get_framework_pathname): Apply patch from Eric Albert 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-cfm.c (cfm_update): Don't initialize dyld_index. * macosx-nat-dyld-info.c (dyld_objfile_entry_clear): Ditto. (dyld_objfile_entry_compare): Don't use dyld_index in comparisons. (dyld_offset_string): Add comment. * macosx-nat-dyld-info.h: Remove dyld_index.

(dyld_info_read): Don't initialize dyld_index. 2004-11-29 Jim Ingham * 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. * macosx-nat-dyld-info.c (dyld_entry_string, dyld_entry_info, dyld_entry_shlib_num): Pedantic cleanups - whitespace, unsigneds, 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.

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 * 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 * ppc-macosx-tdep.c (ppc_mach_o_osabi_sniffer): Sniff the correct side of fat files. * i386-macosx-tdep.c (i386_mach_o_osabi_sniffer): Ditto, and register the sniffer for unknown architectures. 2004-11-18 Jim Ingham * 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 configs. Reimplement. * i386-macosx-tdep.c (osabi_seen_in_attached_dyld): New global, unused. * ppc-macosx-tdep.c (osabi_seen_in_attached_dyld): New global.

(store_inferior_registers): Ditto. * ppc-macosx-frameinfo.c (ppc_frame_saved_regs): Use the word size rather than the register size (word size is 4 on 32 bit apps, but register size is 8). * ppc-macosx-regs.c: (supply_unsigned_int): Zero out buf. (ppc_macosx_fetch_gp_registers_64): Have to supply the mq register so it gets marked valid. * ppc-macosx-tdep.c (ppc_unwind_dummy_id): Use register size, not addr bit. * (ppc_register_virtual_type): Since we always tread the registers as 8 byte, call them long_long. * (ppc_frame_prev_register): wordsize is what gets stored on the stack, not register size. * (ppc_macosx_convert_register_p): New function. * (ppc_macosx_value_to_register): New function. * (ppc_macosx_register_to_value): New function. * (ppc_macosx_init_abi): register the new functions with the 32 bit ABI. 2004-11-11 Jason Molenda (jmolenda@apple.com) * i386-macosx-nat-exec.c, i386-macosx-nat-float.c, i386-macosx-tdep.c, kdp-protocol.c, kdp-transactions.c, kdp-udp.c, machoread.c, macosx-metrowerks.c, macosx-nat-cfm.c, macosx-nat-cfmthread.c, macosx-nat-cmds-load.c, pefread.c, remote-kdp.c, smread.c: St-st-st-st-standards. 2004-11-11 Jason Molenda (jmolenda@apple.com) * ppc-macosx-tdep.c: Stds r tasty. 2004-11-10 Jason Molenda (jmolenda@apple.com) * macosx-nat-dyld.h: Add cpu type/subtype fields to macosx_dyld_thread_status. * macosx-nat-dyld.c (dyld_starts_here_p): In addition to PPC32 magic number, look for other variants that may occur.

This will help keep sync'ed with the get_prev_frame version in more cases. 2004-09-13 Jim Ingham This set of changes converts safe_read_memory_unsigned_integer from returning the memory in a "unsigned long" to a ULONGEST. * ppc-macosx-frameinfo.c: Convert ret_val to ULONGEST. (safe_read_memory_unsigned_integer): Convert pc arg to ULONGEST *. (ppc_parse_instruction): Use unsigned ints for lr_reg & cr_reg so math with a ULONGEST won't sign extend.

(_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 * macosx-nat-dyld-process.c (dyld_add_image_libraries): Add handler for LC_LOAD_WEAK_DYLIB. 2002-11-01 Klee Dienes * symread.c (sym_read_type): Use bfd_bread instead of bfd_read. 2002-11-01 Klee Dienes * 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 * 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 * 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 * 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 * 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 * macosx-nat-dyld-path.c (dyld_resolve_image): Handle the case where the dyld name contains @executable_path. 2002-10-29 Klee Dienes * 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 * 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 * 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 * 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 * 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 * 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 * 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 * macosx-nat-excthread.c (macosx_exception_thread): Include the exception data in exception thread debug output. 2002-10-22 Klee Dienes * i386-macosx-tdep.c (i386_macosx_init_abi): Set the target struct_return field to reg_struct_return. 2002-10-21 Klee Dienes * 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 * macosx-nat-inferior.c (macosx_child_detach): Print "Detaching from program" message when detaching. 2002-10-17 Klee Dienes * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * macosx-nat-mutils.h (__MACH_CHECK_FUNCTION): Update to account for gcc3. 2002-09-24 Klee Dienes * 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 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 * 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 * 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 * (macosx-nat-watchpoint.c): Rename target_range_profitable_for_hw_watchpoint to target_range_ok_for_hw_watchpoint. 2002-08-06 Klee Dienes * 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 * 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 * 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 * 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 * 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 * 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 * ppc-macosx-frameinfo.c (ppc_parse_instructions): properly initialize 'start'. 2002-06-17 Klee Dienes * 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 * 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 * 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 * 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 * macosx-nat.c: remove obsolete (#ifdef 0) exception processing code. 2002-06-07 Jim Ingham * 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 * ppc-macosx-tdep.c, tm-ppc-macosx.h: added a limit argument to ppc_fast_show_stack_helper. 2002-05-24 Klee Dienes * cached-symfile.c: Improve logic to detect mismatch between cached symbol files and object file / GDB versions. 2002-05-24 Klee Dienes * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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.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 * 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 * 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 * 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 * 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 * macosx-nat-dyld.c (dyld_info_process_raw); Treat ':' as a string terminator when reading library names from DYLD. 2002-03-14 James Ingham * 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 * 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 * 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 * 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 * 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 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 * 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 * 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 (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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * macosx-nat-dyld-info.c (dyld_entry_info): Check for e->loaded_name not null before passing to strrchr. 2001-08-02 James Ingham * 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 * 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 * 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 * macosx-nat-dyld.c (section_info_helper): protect the CFM section of the code with #if WITH_CFM . 2001-06-14 James Ingham * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * ppc-frameinfo.c (ppc_frame_cache_properties): Check that the frame's extra_info is set. 2000-11-07 James Ingham * 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 * 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 * ppc-frameinfo.c (ppc_parse_instructions): Cleanup a comment & remove an unused variable. 2000-09-01 James Ingham * 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 * 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 * 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 * 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...
