  10 // Signature class encapsulates a single line of nm output. This line may be
  11 // either an "undefined" name to be resolved, or text or data which resolves
  12 // the unknowns. Some of the features of the Signature class are currently
  13 // unused, such as owner_, which is anticipation of analysis that may lead to
  14 // further code reduction. The premise being that unresolved symbols that are
  15 // defined within otherwise unused code should not be resolved. However this
  16 // information is not available in the output of nm. Further research is
  17 // required.

  19 // Signatures are reference counted to avoid duplication.
