* bfd-in.h (dynamic_lib_link_class): Add DYN_NO_ADD_NEEDED and
DYN_NO_NEEDED.
(bfd_elf_get_dyn_lib_class): New prototype.
* elf.c (bfd_elf_get_dyn_lib_class): New function.
* elflink.c (elf_link_add_object_symbols): Check DYN_AS_NEEDED,
DYN_DT_NEEDED and DYN_NO_NEEDED bits to see if a DT_NEEDED
entry is needed. Issue an error if a DT_NEEDED entry is needed
for a file marked DYN_NO_NEEDED.
(elf_link_check_versioned_symbol): Check the DYN_DT_NEEDED bit
for DT_NEEDED tags.
* bfd-in2.h: Regenerated.
ld/
2004-07-19 H.J. Lu <hongjiu.lu@intel.com>
* emultempl/elf32.em (gld${EMULATION_NAME}_load_symbols): Also
check the add_needed field.
(dt_needed): New struct.
(gld${EMULATION_NAME}_try_needed): Change the first argument
to a pointer to struct dt_needed. Check the DYN_NO_ADD_NEEDED
bit in the file where the DT_NEEDED entry comes from.
(gld${EMULATION_NAME}_search_needed): Change the second
argument to a pointer to struct dt_needed.
(gld${EMULATION_NAME}_check_ld_so_conf): Updated.
(gld${EMULATION_NAME}_after_open): Likewise.
* ld.texinfo: Add --add-needed document.
* ldlang.c (new_afile): Set p->add_needed.
* ldlang.h (lang_input_statement_type): Add add_needed field.
* ldmain.h (add_needed): Declare.
* ldmain.c (add_needed): New global var.
* lexsup.c (option_values): Add OPTION_ADD_NEEDED and
OPTION_NO_ADD_NEEDED.
(ld_options): Likewise.
(parse_args): Handle them.
