Subject: [PATCH v4 3/5] firmware: Explicitly pass -pie to the linker, not just the driver
Date: Fri, 9 Jul 2021 20:34:21 +0100 [thread overview]
Message-ID: <20210709193423.29712-4-jrtc27@jrtc27.com> (raw)
In-Reply-To: <20210709193423.29712-1-jrtc27@jrtc27.com>
When using Clang with a bare-metal triple, -pie does not get passed to
the linker as it's not normally a thing that makes sense. However, in
our case it is, and manually forwarding it on works as desired, so do so
to fully support FW_PIC with Clang, including when linking with LLD.
