You use %= inside the label names, e.g. "label%=x01".
The source says:
%= outputs a number which is unique to each insn in the entire
compilation. This is useful for making local labels that are
referred to more than once in a given insn.
Beware, old cc on i386-nextstep doesn't support this syntax (it's a
too old version of gcc).
