Subject: [PATCH v2 04/14] arm: Enable thumb2 mode in assembly files
Date: Fri, 01 Mar 2013 17:36:00 -0000	[thread overview]
Message-ID: <1362159320-5934-5-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1362159320-5934-1-git-send-email-rth@twiddle.net>

The preceeding patches have allowed for the few incompatibilities
between arm and thumb2 mode, or have marked the file as not wanting
to use thumb2 mode.
---
	* sysdeps/arm/sysdep.h [__ASSEMBLER__]: Enable thumb2 if __thumb2__.
	(PC_OFS): Respect __thumb__ if __ASSEMBLER__.
