I've got a loose plan in my head for how to clean up handling of reverse-endian load/store instructions at both the translator and tcg backend levels. Hopefully it make the ppc, sparc, and s390 targets cleaner. I would think that would equally apply to the arm setend. r~ From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from eggs.gnu.org ([2001:4830:134:3::10]:55129) by lists.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1VEgnw-0001Cm-Br for qemu-devel@nongnu.org; Wed, 28 Aug 2013 10:33:11 -0400 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1VEgnp-00053q-29 for qemu-devel@nongnu.org; Wed, 28 Aug 2013 10:33:04 -0400 Sender: Richard Henderson Message-ID: <521E09DF.20102@twiddle.net> Date: Wed, 28 Aug 2013 07:31:59 -0700 From: Richard Henderson MIME-Version: 1.0 References: <1377664796-11698-1-git-send-email-sw@weilnetz.de> In-Reply-To: Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Subject: Re: [Qemu-devel] [PATCH] target-arm: Report unimplemented opcodes (LOG_UNIMP) List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Peter Maydell Cc: qemu-trivial , Stefan Weil , qemu-devel , Paul Brook On 08/28/2013 01:15 AM, Peter Maydell wrote: > [*] not impossible, we already do something on the ppc > that's similar; however I'd really want to take the time to > figure out how to do endianness swapping "properly" > and what qemu does currently before messing with it.
