Subject: [PATCH 2/5] selftests/powerpc: Standardise TM calls
Date: Wed, 23 Dec 2015 16:49:51 +1100 [thread overview]
Message-ID: <1450849794-23174-3-git-send-email-rashmicy@gmail.com> (raw)
In-Reply-To: <1450849794-23174-1-git-send-email-rashmicy@gmail.com>
Currently tbegin, tend etc are written as opcodes or asm instructions. So
standardise these to asm instructions.
