Subject: [PATCH] SH: Delete unnecessary mov in the top of interrupt
Date: Mon, 08 Dec 2008 14:04:11 +0000 [thread overview]
Message-ID: <493D295B.1010806@gmail.com> (raw)
Hi, all.
I think that to move INTEVT address to the scratch reg in the top of
interrupt is already unnecessary.
So this patch delete it.
