Subject: [PATCH 02/37] kbuild: refactor tagets caluculation for KBUILD_{BUILTIN,KBUILD_MODULES}
Date: Mon, 1 Jun 2020 14:56:56 +0900 [thread overview]
Message-ID: <20200601055731.3006266-2-masahiroy@kernel.org> (raw)
In-Reply-To: <20200601055731.3006266-1-masahiroy@kernel.org>
Remove lib-target, builtin-target, modorder-target, and modtargets.
Instead, add targets-for-builtin and targets-for-modules.
