2000-10-24 Kevin Buettner <kevinb@redhat.com>
* solib-svr4.c: New file created out of much of solib.c...
* solib.c (_SYSCALL32, BKPT_AT_SYMBOL): Move these defines to
solib-svr4.c.
(sys/types.h, signal.h, sys/param.h, fcntl.h, a.out.h,
elf/external.h, link.h): Move these includes to solib-svr4.c.
(bkpt_names, debug_base_symbols, main_name_list,
solib_extract_address, SOLIB_EXTRACT_ADDRESS, dynamic_copy,
ld_2_copy, debug_addr, flag_addr, LM_ADDR, LM_NEXT, LM_NAME,
IGNORE_FIRST_LINK_MAP_ENTRY, breakpoint_addr,
allocate_rt_common_objfile, solib_add_common_symbols,
bfd_lookup_symbol, look_for_base, elf_locate_base, locate_base,
first_link_map_member, open_symbol_file_object, match_main,
current_sos, interp_text_sect_low, interp_text_sect_high,
interp_plt_sect_low, interp_plt_sect_high,
in_svr4_dynsym_resolve_code, disable_break, enable_break,
special_symbol_handling): Moved to solib-svr4.c.
(debug32_copy, shadow_contents, fdmatch)
Removed entirely.
(struct so_list): Moved to solist.h
(MAX_PATH_SIZE): Moved to solist.h and renamed to
SO_NAME_MAX_PATH_SIZE.
* solist.h: New file created from struct so_list in solib.c.
(struct lm_info): Add forward declaration.
(struct so_list): Remove fields lm, lm32, lmaddr. Replace with a
single field, lm_info, which will be a pointer to target specific
data.
(struct target_so_ops): New struct.
(free_so): Add extern declaration.
(current_target_so_ops): Declare new global variable.
(solib_map_sections):
(TARGET_SO_LM_ADDR, TARGET_SO_FREE_SO, TARGET_SO_CLEAR_SOLIB,
TARGET_SO_SOLIB_CREATE_INFERIOR_HOOK,
TARGET_SO_SPECIAL_SYMBOL_HANDLING, TARGET_SO_CURRENT_SOS,
TARGET_SO_OPEN_SYMBOL_FILE_OBJECT): New macros.
* solib.c (solib_map_sections, free_so, symbol_add_stub,
update_solib_list, solib_add, info_shared_library_command,
solib_address, clear_solib, solib_create_inferior_hook): Use
new TARGET_SO_* macros to call function on target specific
side indirectly.
(current_target_so_ops): Define new global variable.
(_initialize_solib): Eliminate HAVE_LINK_H ifdef.
* solib-svr4.h: New file; defines struct link_map_offsets and
SVR4_FETCH_LINK_MAP_OFFSETS.
* solib-svr4.c (_initialize_svr4_solib, svr4_clear_solib,
svr4_free_so): New functions.
(special_symbol_handling, solib_create_inferior_function_hook,
current_sos): Rename by adding a svr4_ prefix.
(default_svr4_fetch_link_map_offsets): New function.
(LM_ADDR, LM_NEXT, LM_NAME, IGNORE_FIRST_LINK_MAP_ENTRY,
first_link_map_member, open_symbol_file_object, svr4_current_sos):
Remove dependence on existence of link.h by calling
SVR4_FETCH_LINK_MAP_OFFSETS to obtain the offsets of shared library
data. As a result, SVR4 and non-SVR4 versions of many of these
functions coalesce into a single function and HAVE_STRUCT_LINK_MAP32
ugliness is moved into default_svr4_fetch_link_map_offsets where it
is relatively contained.
(SOLIB_EXTRACT_ADDRESS): Revert 2000-08-29 change in which
solib_extract_address() is called instead of extract_address().
(solib_extract_address): Removed.
* Makefile.in (solib.o): Add solist.h as a dependency.
(solib-svr4.o): Add dependencies.
* sparc-tdep.c (gregset.h): Don't include unless USE_PROC_FS is
defined.
