Subject: [Xen-devel] [XEN PATCH v3 12/23] xen/build: Move as-option-add to xen/
Date: Wed, 26 Feb 2020 11:33:44 +0000 [thread overview]
Message-ID: <20200226113355.2532224-13-anthony.perard@citrix.com> (raw)
In-Reply-To: <20200226113355.2532224-1-anthony.perard@citrix.com>
Only xen/ uses as-option-add and as-insn, so there aren't needed in
Config.mk.
Signed-off-by: Anthony PERARD <anthony.perard@citrix.com>
