[Qemu-devel] [PULL 02/11] pc-bios/s390-ccw: Use proper register names for Clang

[Cornelia Huck <cohuck@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

When compiling the s390-ccw firmware with Clang 7.0.1, I get the
following errors:

pc-bios/s390-ccw/start.S:62:19: error: invalid use of length addressing
        stctg 0,0,0(15)
                  ^

        oi 6(15), 0x2

pc-bios/s390-ccw/start.S:79:12: error: invalid operand for instruction
        br 14
           ^

Let's use proper register names like in the rest of this file to fix it.
