848 | ||
849 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
850 | to handle the relocations for a section. | |
851 | ||
852 | The relocs are always passed as Rela structures; if the section | |
853 | actually uses Rel structures, the r_addend field will always be | |
854 | zero. | |
855 | ||
856 | This function is responsible for adjusting the section contents as | |
857 | necessary, and (if using Rela relocs and generating a relocateable | |
858 | output file) adjusting the reloc addend as necessary. | |
859 | ||
860 | This function does not have to worry about setting the reloc | |
861 | address or the reloc symbol index. | |
862 | ||
863 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
864 | ||
865 | LOCAL_SECTIONS is an array giving the section in the input file | |
866 | corresponding to the st_shndx field of each local symbol. | |
867 | ||
868 | The global hash table entry for the global symbols can be found | |
869 | via elf_sym_hashes (input_bfd). | |
870 | ||
871 | When generating relocateable output, this function must handle | |
872 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is | |
873 | going to be the section symbol corresponding to the output | |
874 | section, which means that the addend must be adjusted | |
875 | accordingly. */ | |
