Subject: [PATCH] aarch64: Fix the documentation on :pg_hi21:
Date: Thu, 29 May 2014 17:58:00 -0000 [thread overview]
Message-ID: <1401386309-16156-1-git-send-email-martin@martin.st> (raw)
In-Reply-To: <alpine.DEB.2.02.1405292057290.14339@cone.martin.st>
The syntax described, including a leading '#', was not supported
in practice. (For :lo12: it is optional.)
---
Removed the # from the declaration of :lo12: as well - the
'#' isn't a part of the :lo12: prefix itself but is part of how
the symbol is used in the instruction.
