Subject: [PATCH 5/8] arm64: Add assembly annotations for weak-PI-alias madness
Date: Tue, 11 May 2021 17:12:35 +0100 [thread overview]
Message-ID: <93210932f8a83f88c69195d5c72a3c1bf4b02222.1620738177.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1620738177.git.robin.murphy@arm.com>
Add yet another set of assembly symbol annotations, this time for the
borderline-absurd situation of a function aliasing to a weak symbol
which itself also wants a position-independent alias.
Signed-off-by: Robin Murphy <robin.murphy@arm.com>
