Subject: [GIT] kbuild/lto changes for 3.15-rc1
Date: Mon, 7 Apr 2014 22:19:19 +0200 [thread overview]
Message-ID: <20140407201919.GA15838@sepie.suse.cz> (raw)
Hi Linus,
besides the kbuild branch, here is the LTO build support by Andi. It is
a separate branch, because it depends on other patches by Andi which
were merged through other trees. The link-time-optimization build is an
experimental feature, so there one kconfig option to enable it and
another kconfig option to disable it (behind a door with a sign "Beware
of the Leopard"...), so that it is not enabled by
allmodconfig/allyesconfig.
Thanks,
Michal
