--export-dynamic-symbol-list is like a dynamic list, but without the symbolic property for unspecified symbols. When creating an executable, --export-dynamic-symbol-list is treated like --dynamic-list. When creating a shared library, it is treated like --dynamic-list if -Bsymbolic or --dynamic-list are used, otherwise, it is ignored, so that references to matched symbols will not be bound to the definitions within the shared library. PR ld/25910 * NEWS: Mention --export-dynamic-symbol[-list]. * ld.texi: Document --export-dynamic-symbol[-list]. * ldgram.y: Pass current_dynamic_list_p to lang_append_dynamic_list. * ldlang.c (current_dynamic_list_p): New. (ang_append_dynamic_list): Updated to take a pointer to struct bfd_elf_dynamic_list * argument instead of using link_info.dynamic_list. (lang_append_dynamic_list_cpp_typeinfo): Pass &link_info.dynamic_list to ang_append_dynamic_list. (lang_append_dynamic_list_cpp_new): Likewise. * ldlang.h (current_dynamic_list_p): New. (lang_append_dynamic_list): Add a pointer to struct bfd_elf_dynamic_list * argument. * ldlex.h (option_values): Add OPTION_EXPORT_DYNAMIC_SYMBOL and OPTION_EXPORT_DYNAMIC_SYMBOL_LIST. * lexsup.c (ld_options): Add entries for OPTION_EXPORT_DYNAMIC_SYMBOL and OPTION_EXPORT_DYNAMIC_SYMBOL_LIST. (parse_args): Handle --export-dynamic-symbol and --export-dynamic-symbol-list. * testsuite/ld-dynamic/export-dynamic-symbol-1.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-2.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-glob.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-list-1.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-list-2.d: New. * testsuite/ld-dynamic/export-dynamic-symbol-list-glob.d: New. * testsuite/ld-dynamic/export-dynamic-symbol.exp: New. * testsuite/ld-dynamic/export-dynamic-symbol.s: New. * testsuite/ld-dynamic/foo-bar.list: New. * testsuite/ld-dynamic/foo.list: New. * testsuite/ld-dynamic/foo.s: New. * testsuite/ld-dynamic/fstar.list: New. * testsuite/ld-elf/dlempty.list: New. * testsuite/ld-elf/shared.exp: Add tests for --export-dynamic-symbol and --export-dynamic-symbol-list.
