Subject: [Qemu-devel] [PATCH] linux-user: fix running programs with iwmmxt instructions
Date: Mon, 15 Mar 2010 13:39:32 +0100	[thread overview]
Message-ID: <20100315123932.GB8895@firewall> (raw)


When using linux-user for emulating an pxa270 we cannot generate an illegal
instruction trap to the kernel to save/load the iwmmxt registers.
