The %z modifier is IMO not intended for general use, so I don't think the
backport will be done. However, you could just use
out (unsigned port, T val)
{
asm volatile ("out %0, %w1" : : "a" (val), "Nd" (port));
}
(i.e. "out" insn without any decorations), and correct code will be generated.
At least recent binutils will handle all cases, including unsigned long on
x86_64.
