Subject: [PATCH v2 2/2] x86: set a dependency on macros.S
Date: Wed, 14 Nov 2018 12:43:09 -0800	[thread overview]
Message-ID: <20181114204309.18645-3-namit@vmware.com> (raw)
In-Reply-To: <20181114204309.18645-1-namit@vmware.com>

Changes in macros.S should trigger the recompilation of all C files, as
the macros might need to affect their compilation.
