Running qemu-hexagon with a binary that was compiled for an arch version unknown by qemu can produce a somewhat confusing message: qemu-hexagon: unable to find CPU model 'unknown' Let's give a bit more info by appending the eflags so that the message becomes: qemu-hexagon: unable to find CPU model 'unknown (0x69)' Signed-off-by: Matheus Tavares Bernardino <quic_mathbern@quicinc.com> Signed-off-by: Taylor Simpson <tsimpson@quicinc.com> Tested-by: Taylor Simpson <tsimpson@quicinc.com> Reviewed-by: Taylor Simpson <tsimpson@quicinc.com> Message-Id: <8a8d013cc619b94fd4fb577ae6a8df26cedb972b.1683225804.git.quic_mathbern@quicinc.com>
