Subject: [PATCH v2 2/2] kbuild: Cache a few more calls to the compiler
Date: Wed, 4 Oct 2017 15:37:17 -0700 [thread overview]
Message-ID: <20171004223717.3010-3-dianders@chromium.org> (raw)
In-Reply-To: <20171004223717.3010-1-dianders@chromium.org>
These are a few stragglers that I left out of the original patch to
cache calls to the C compiler ("kbuild: Add a cache for generated
variables") because they bleed out into the main Makefile and thus
uglify things a little bit. The idea is the same here, though.
