6213 | global symbol which is defined in an object we are | |

6218 | possibility below by storing information in the | |

6220 | situation occurs when creating shared libraries and symbol | |
6221 | visibility changes render the symbol local. | |

6224 | may need to keep relocations for symbols satisfied by a | |
6225 | dynamic library if we manage to avoid copy relocs for the | |
