We need to make an IR symbol visible if it is defined in an IR object and referenced in a dynamic object. When --as-needed is used, since linker removes the IR symbol reference of the dynamic object if the dynamic object isn't needed in the first pass, the IR definition isn't visible to the dynamic object even if the dynamic object becomes needed in the second pass. Add dynamic_ref_after_ir_def to bfd_link_hash_entry to track IR symbol which is defined in an IR object and later referenced in a dynamic object. dynamic_ref_after_ir_def is preserved when restoring the symbol table for unneeded dynamic object. bfd/ PR ld/21382 * elflink.c (elf_link_add_object_symbols): Preserve dynamic_ref_after_ir_def when restoring the symbol table for unneeded dynamic object. include/ PR ld/21382 * bfdlink.h (bfd_link_hash_entry): Add dynamic_ref_after_ir_def. ld/ PR ld/21382 * plugin.c (is_visible_from_outside): Symbol may be visible from outside if dynamic_ref_after_ir_def is set. (plugin_notice): Set dynamic_ref_after_ir_def if the symbol is defined in an IR object and referenced in a dynamic object. * testsuite/ld-plugin/lto.exp: Run PR ld/21382 tests. * testsuite/ld-plugin/pr21382a.c: New file. * testsuite/ld-plugin/pr21382b.c: Likewise.
