| 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. |
