2407 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
2408 | to handle the relocations for a section. | |

2411 | actually uses Rel structures, the r_addend field will always be | |
2412 | zero. | |

2414 | This function is responsible for adjust the section contents as | |
2415 | necessary, and (if using Rela relocs and generating a | |
1049f94e | 2416 | relocatable output file) adjusting the reloc addend as |
252b5132 RH |
2417 | necessary. |

2419 | This function does not have to worry about setting the reloc | |
2420 | address or the reloc symbol index. | |

2422 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
2423 | ||
2424 | LOCAL_SECTIONS is an array giving the section in the input file | |
2425 | corresponding to the st_shndx field of each local symbol. | |
2426 | ||
2427 | The global hash table entry for the global symbols can be found | |
2428 | via elf_sym_hashes (input_bfd). | |
2429 | ||
1049f94e | 2430 | When generating relocatable output, this function must handle |
252b5132 RH |
2431 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is |
