Linker plugin_maybe_claim is the interface of linker plugin support. This patch extracts linker plugin_maybe_claim into plugin_object_p and makes it available to BFD via a new function: void register_ld_plugin_object_p (const bfd_target *(*) (bfd *)); bfd_plugin_object_p calls plugin_object_p registered by linker first. It adds an enum bfd_plugin_format field and a pointer to plugin dummy BFD so that plugin_object_p stores plugin dummy BFD to allow plugin_maybe_claim to retrieve it later. bfd/ PR ld/17878 * bfd.c (bfd_plugin_format): New. (bfd): Add plugin_format and plugin_dummy_bfd. * plugin.c (try_load_plugin): Take a pointer to bfd_boolean argument to return TRUE if any plugin is found. Set plugin_format. (has_plugin): New. (bfd_plugin_target_p): New. (bfd_plugin_specified_p): Likewise. (bfd_plugin_target_p): Likewise. (register_ld_plugin_object_p): Likewise. (bfd_plugin_set_plugin): Set has_plugin. (load_plugin): Cache try_load_plugin result. (bfd_plugin_object_p): Try ld_plugin_object_p first. Check plugin_format. * plugin.h (bfd_plugin_target_p): New. (bfd_plugin_specified_p): Likewise. (register_ld_plugin_object_p): Likewise. * bfd-in2.h: Regenerated. ld/ PR ld/17878 * plugin.c: Include ../bfd/plugin.h. (plugin_get_ir_dummy_bfd): Call bfd_create with link_info.output_bfd instead of srctemplate. Copy BFD info from srctemplate only if it doesn't use BFD plugin target vector. (plugin_load_plugins): Call register_ld_plugin_object_p with (plugin_object_p) (plugin_maybe_claim): Renamed to ... (plugin_object_p): This. Return dummy BFD target vector if input is calimed by plugin library, otherwise return NULL. Update plugin_format and plugin_dummy_bfd. (plugin_maybe_claim): New. Use plugin_object_p. xx
