From afa974b771281fd89e8fdcb71152152f17fb8303 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 17 Jan 2019 19:02:43 +0900 Subject: kbuild: add real-prereqs shorthand for $(filter-out FORCE,$^) In Kbuild, if_changed and friends must have FORCE as a prerequisite. Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common idiom to get the names of all the prerequisites except phony targets. Add real-prereqs as a shorthand. Note: We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ may include auto-generated dependencies from the .*.cmd file when a single object module is changed into a multi object module. Refer to commit 69ea912fda74 ("kbuild: remove unneeded link_multi_deps"). I added some comment to avoid accidental breakage.
