+Subject: [PATCH 3/7] gold: Initial TLS relocation scan support
+
+Add need_tls_process_relocs_ and input_objects_ to Target to allow TLS
+relocation scan for TLSDESC -> IE relaxation in shared object.
+
+	PR gold/25476
+	* target.h (Target): Add need_tls_process_relocs, input_objects,
+	set_input_objects, set_need_tls_process_relocs,
+	need_tls_process_relocs_ and input_objects_.
+	(Target::Target): Initialize need_tls_process_relocs_ and
+	input_objects_.
