Using arm-linux-gnueabi-gcc 4.7.3-1ubuntu1 on Ubuntu 13.04 to compiled the m5 binary yields the error: m5op_arm.S: Assembler messages: m5op_arm.S:85: Error: selected processor does not support ARM mode `bxj lr' For each of of the SIMPLE_OPs. Apparently, this compiler doesn't like the interworking of these code types for the default arch. Adding -march=armv7-a makes it compile. Another alternative that I found to work is replacing the bxj lr instruction with mov pc, lr, but I don't know how that affects the KVM stuff and if bxj is needed.
