Subject: [Qemu-devel] [PULL 22/28] target-mips/translate.c: Update OPC_SYNCI
Date: Wed, 15 Oct 2014 10:54:14 +0100	[thread overview]
Message-ID: <1413366860-7833-23-git-send-email-leon.alrae@imgtec.com> (raw)
In-Reply-To: <1413366860-7833-1-git-send-email-leon.alrae@imgtec.com>

From: Dongxue Zhang <elta.era@gmail.com>

Update OPC_SYNCI with BS_STOP, in order to handle the instructions which saved
in the same TB of the store instruction.
