Subject: [PATCH 04/11] KVM: PPC: fix incorrect element_size for stxsiwx in analyse_instr
Date: Wed, 25 Apr 2018 19:54:37 +0800 [thread overview]
Message-ID: <1524657284-16706-5-git-send-email-wei.guo.simon@gmail.com> (raw)
In-Reply-To: <1524657284-16706-1-git-send-email-wei.guo.simon@gmail.com>
From: Simon Guo <wei.guo.simon@gmail.com>
stwsiwx will place contents of word element 1 of VSR into word
storage of EA. So the element size of stwsiwx should be 4.
This patch correct the size from 8 to 4.
