* solib.c (symbol_add_stub): Remember the index and the name of the section with the lowest address. Use this data (instead of data from .text) to pass info into symbol_file_add. * elfread.c (record_minimal_symbol_and_info): Use the section where the symbol lives to get the index, instead of guessing.
2000-05-052000-05-03 Michael Snyder <msnyder@seadog.cygnus.com>Michael Snyder1-49/+67
* solib.c (elf_locate_base, info_sharedlibrary_command): Look at the bfd to determine if it is elf32 or elf64, rather than using an ifdef. This makes it runtime teststable and multi-arch.

* symfile.h (struct section_addr_info ): Remove fields for special treatment of .text, .data and .bss sections. * solib.c (symbol_add_stub): The special field text_addr is not available anymore. Search for the .text field the hard way. * symfile.c (build_section_addr_info_from_section_table): Don't fill in {text, data, bss}_addr any more. (default_symfile_offsets): Don't use {text, data, bss}_addr fields to fill in section_offsets for objfile. (syms_from_objfile): Don't deal with {text, data, bss}_addr as a special case anymore. (add_symbol_file_command): Ditto.
2000-04-05* solib.c (update_solib_list): New function.Jim Blandy1-30/+54
(solib_add): Call update_solib_list, and then read symbols. (info_sharedlibrary_command): Call update_solib_list, not solib_add.
2000-04-042000-04-03 H.J. Lu <hjl@gnu.org>H.J. Lu1-1/+1
* gdb_regex.h: New. Include "regex.h" if USE_INCLUDED_REGEX is defined and <regex.h> otherwise. * irix5-nat.c: Include "gdb_regex.h" instead of "gnu-regex.h". * monitor.c: Likewise. * osfsolib.c: Likewise. * solib.c: Likewise. * source.c: Likewise. * symtab.c: Likewise. * Makefile.in (REGEX): Changed to @REGEX@. (REGEX_CFLAGS): New. (REGEX1): Removed. (ADD_DEPS): Use $(REGEX) instead of $(REGEX1). (INTERNAL_WARN_CFLAGS): Add $(REGEX_CFLAGS). * configure.in (--with-included-regex): New switch. (REGEX): New. Subsstitue @REGEX@ in Makefile.in. (REGEX_CFLAGS): New. Subsstitue @REGEX_CFLAGS@ in Makefile.in. * configure: Regenerated.
2000-04-03* solib.c (solib_add): Move all the code for loading symbol tablesJim Blandy1-33/+51
below the code to sort out additions and removals. That way, we always catch all loaded shared libraries whose symbols we haven't grabbed yet. * solib.c (solib_add): Don't try to free a shared object's objfile if it doesn't have one. Duh. * solib.c (solib_add): If a pattern was given, but it doesn't match any currently loaded shared libraries, print a message; don't just be silent.
2000-03-242000-03-23 Michael Snyder <msnyder@cleaver.cygnus.com>Michael Snyder1-7/+6
* solib.c (open_symbol_file_object): to sneak an int argument past catch_errors, instead of casting it to a pointer, simply pass it by address.

2000-03-17* solib.c (solib_add): Delete debugging code.Jim Blandy1-23/+0
2000-03-16* solib.c (current_sos): Be more careful about freeing the newJim Blandy1-3/+4
so_list node if an error occurs.
2000-03-15Deal with the inferior unloading shared objects.Jim Blandy1-259/+422
* solib.c (current_sos): New function, replacing find_solib. (find_solib): Deleted. (free_so): New function. (clear_solib): Call free_so, instead of writing it out. (solib_add): Rewritten: compare the inferior's current list of shared objects with GDB's list, and do the required loads and unloads. (info_sharedlibrary_command, solib_address): Don't use find_solib to walk the list of shared libraries: call solib_add, and then walk the list at so_list_head normally. * objfiles.c (free_objfile): Don't call CLEAR_SOLIB, and don't detach the core target. These tasks are taken care of elsewhere. * target.c (remove_target_sections): New function. * target.h (remove_target_sections): New declaration. * solib.c (symbol_add_stub): Check whether we've already created an objfile for this shared object first, before doing all that work to compute section addresses, etc. * objfiles.c (unlink_objfile): Report an internal error if objfile doesn't occur in the object_files list. * solib.c (special_symbol_handling): Delete argument; it's not used. * solib.c (SOLIB_EXTRACT_ADDRESS): New macro to extract addresses from solib structures. Use it throughout solib.c, get rid of all CORE_ADDR casts. (struct so_list): Change type of lmaddr to CORE_ADDR. (first_link_map_member): Change return value type to CORE_ADDR, update callers. (solib_add_common_symbols): Change parameter type to CORE_ADDR, update callers. (open_symbol_file_object, find_solib): Change type of lm variable to CORE_ADDR.

(enable_break): For SVR4 systems, first try to use the debugger interfaces in the dynamic linker to track shared library events as they happen, then fall back to BKPT_AT_SYMBOL code. Convert BKPT_AT_SYMBOL code to use shared library event breakpoints. (solib_create_inferior_hook): Simplify BKPT_AT_SYMBOL code, it no longer needs to restart/wait on the inferior. * symfile.c (find_lowest_section): No longer static. * symfile.h (find_lowest_section): Corresponding changes.
