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