When a branch count is reported without an address it is because a branch has failed the prediction. However, when an address is
reported along with a branch count, it will be because the packet was initiated by an uninferable discontinuity, an exception, or
because a branch has been encountered when \textbf{branch\_count} is 0xffff\_ffff. For the latter case, the
because a branch has been encountered that increments \textbf{branch\_count} to 0xffff\_ffff. For the latter case, the
reported address will always be for a branch, and in the former cases it may be. If it is a branch,
it is necessary to be explicit about whether or not the prediction was met or not. If it is met, then the reported address is
that of the last correctly predicted branch.
