Subject: [PATCH 7/8] kbuild: refactor if_changed and if_changed_dep
Date: Thu, 15 Nov 2018 17:27:14 +0900	[thread overview]
Message-ID: <1542270435-11181-8-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1542270435-11181-1-git-send-email-yamada.masahiro@socionext.com>

'@set -e; $(echo-cmd) $(cmd_$(1)' can be replaced with '$(cmd)'.
More cleanups.
