* 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.

* 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.

e8930304b2 * solib.c (solib_add): Move all the code for loading symbol tables 
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.

* 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.

07cd4b9723 Deal with the inferior unloading shared objects. 
* 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.

b420cea7eb Handle missing shared libraries during the examination of a core 
dump gracefully.

464c6c5f3f * solib.c (solib_break_names): Define for Solaris and Linux. 
(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.

Wraps up 7763 work, simplifies BKPT_AT_SYMBOL code somewhat, and allows
