Subject: [PATCH] kbuild: consolidate single targets
Date: Tue, 30 Oct 2018 13:32:45 +0900	[thread overview]
Message-ID: <1540873965-31342-1-git-send-email-yamada.masahiro@socionext.com> (raw)

Instead of specifying target/source pairs, let's list patterns that we
want to handle as single targets. This slightly changes the behavior;
the top Makefile previously checked the presence of a source file,
now Kbuild will descend into a subdirectory anyway to find out what to
do there.
