non_ir_ref_dynamic
dynamic_ref_after_ir_def is a little odd compared to other symbol flags in that as the name suggests, it is set only for certain references after a definition. It turns out that setting a flag for any non-ir reference from a dynamic object can be used to solve the problem for which this flag was invented, which I think is a cleaner. This patch does that, and sets non_ir_ref only for regular object references. include/ * bfdlink.h (struct bfd_link_hash_entry): Update non_ir_ref comment. Rename dynamic_ref_after_ir_def to non_ir_ref_dynamic. ld/ * plugin.c (is_visible_from_outside): Use non_ir_ref_dynamic. (plugin_notice): Set non_ir_ref for references from regular objects, non_ir_ref_dynamic for references from dynamic objects. bfd/ * elf64-ppc.c (add_symbol_adjust): Transfer non_ir_ref_dynamic. * elflink.c (elf_link_add_object_symbols): Update to use non_ir_ref_dynamic. (elf_link_input_bfd): Test non_ir_ref_dynamic in addition to non_ir_ref. * linker.c (_bfd_generic_link_add_one_symbol): Likewise.
