// This file contains the PassNameParser and FilteredPassNameParser<> classes,
// which are used to add command line arguments to a utility for all of the
// passes that have been registered into the system.
//
// The PassNameParser class adds ALL passes linked into the system (that are
// creatable) as command line arguments to the tool (when instantiated with the
// appropriate command line option template).  The FilteredPassNameParser<>
// template is used for the same purposes as PassNameParser, except that it only
// includes passes that have a PassType that are compatible with the filter
// (which is the template argument).
//
// Note that this is part of the legacy pass manager infrastructure and will be
// (eventually) going away.
