  23 // The goal of this program is to verify is strings are handled correctly
  24 // by ICF.  ICF inlines strings that can be merged.  In some cases, the
  25 // addend of the relocation pointing to a string merge section must be
  26 // ignored.  This program has no pair of identical functions that can be
  27 // folded.  However, if the addend is not ignored then get2 and get3 will
  28 // become identical.
