1218 | ||
1219 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
1220 | to handle the relocations for a section. | |
1221 | ||
1222 | The relocs are always passed as Rela structures; if the section | |
1223 | actually uses Rel structures, the r_addend field will always be | |
1224 | zero. | |
1225 | ||
1226 | This function is responsible for adjusting the section contents as | |
1227 | necessary, and (if using Rela relocs and generating a relocatable | |
1228 | output file) adjusting the reloc addend as necessary. | |
1229 | ||
1230 | This function does not have to worry about setting the reloc | |
1231 | address or the reloc symbol index. | |
1232 | ||
1233 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
1234 | ||
1235 | LOCAL_SECTIONS is an array giving the section in the input file | |
1236 | corresponding to the st_shndx field of each local symbol. | |
1237 | ||
1238 | The global hash table entry for the global symbols can be found | |
1239 | via elf_sym_hashes (input_bfd). | |
1240 | ||
1241 | When generating relocatable output, this function must handle | |
1242 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is | |
1243 | going to be the section symbol corresponding to the output | |
1244 | section, which means that the addend must be adjusted | |
1245 | accordingly. */ | |
