Subject: [PATCH v2 5/8] arm64: Add assembly annotations for weak-PI-alias madness
Date: Thu, 27 May 2021 16:34:45 +0100	[thread overview]
Message-ID: <75545b3c4129b20b887474bb58a9cf302bf2132b.1622128527.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1622128527.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>
