1250 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
1251 | to handle the relocations for a section. | |
1252 | ||
1253 | The relocs are always passed as Rela structures; if the section | |
1254 | actually uses Rel structures, the r_addend field will always be | |
1255 | zero. | |
1256 | ||

1258 | necessary, and (if using Rela relocs and generating a relocatable | |
1259 | output file) adjusting the reloc addend as necessary. | |
1260 | ||
1261 | This function does not have to worry about setting the reloc | |
1262 | address or the reloc symbol index. | |
1263 | ||
1264 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
1265 | ||
1266 | LOCAL_SECTIONS is an array giving the section in the input file | |
1267 | corresponding to the st_shndx field of each local symbol. | |
1268 | ||
1269 | The global hash table entry for the global symbols can be found | |
1270 | via elf_sym_hashes (input_bfd). | |
1271 | ||
1272 | When generating relocatable output, this function must handle | |
1273 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is | |
1274 | going to be the section symbol corresponding to the output | |
