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. */
