Subject: [PATCH v2 06/14] arm: Delete LOADREGS macro
Date: Fri, 01 Mar 2013 17:36:00 -0000	[thread overview]
Message-ID: <1362159320-5934-7-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1362159320-5934-1-git-send-email-rth@twiddle.net>

There was only one user.  It's "condition" argument was used
for "ia" rather than an actual condition.  The apcs26 syntax
is almost certainly not needed, given current binutils requirements.

        * sysdeps/arm/__longjmp.S (__longjmp): Use ldmia insn directly.
        * sysdeps/arm/sysdep.h (LOADREGS): Remove.
