Lu * 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 * 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. --- ld/ldlang.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'ld/ldlang.h') diff --git a/ld/ldlang.h b/ld/ldlang.h index 0b56c27..f7e2fa6 100644 --- a/ld/ldlang.h +++ b/ld/ldlang.h @@ -266,6 +266,10 @@ typedef struct lang_input_statement_struct /* Whether to search for this entry as a dynamic archive. */ bfd_boolean dynamic; + /* Whether DT_NEEDED tags should be added for dynamic libraries in + DT_NEEDED tags from this entry. */ + bfd_boolean add_needed; + /* Whether this entry should cause a DT_NEEDED tag only when satisfying references from regular files, or always. */ bfd_boolean as_needed; -- cgit v1.1
