Subject: [Qemu-devel] [PATCH 1/2] s390x: add TR function for EXECUTE
Date: Thu, 12 Jan 2012 18:43:26 +0100	[thread overview]
Message-ID: <1326390207-2650-2-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1326390207-2650-1-git-send-email-agraf@suse.de>

Newer gcc versions (or glibc?) also generate code that tries to EXECUTE
the TR opcode. Implement it so that we don't break valid guests.
