478 There is some attempt to make this function usable for many architectures,
479 both USE_REL and USE_RELA ['twould be nice if such a critter existed],
480 if only to serve as a learning tool.
482 The RELOCATE_SECTION function is called by the new ELF backend linker
483 to handle the relocations for a section.
485 The relocs are always passed as Rela structures; if the section
486 actually uses Rel structures, the r_addend field will always be
489 This function is responsible for adjusting the section contents as
490 necessary, and (if using Rela relocs and generating a relocatable
491 output file) adjusting the reloc addend as necessary.
493 This function does not have to worry about setting the reloc
494 address or the reloc symbol index.
496 LOCAL_SYMS is a pointer to the swapped in local symbols.
498 LOCAL_SECTIONS is an array giving the section in the input file
499 corresponding to the st_shndx field of each local symbol.
501 The global hash table entry for the global symbols can be found
502 via elf_sym_hashes (input_bfd).
504 When generating relocatable output, this function must handle
505 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
506 going to be the section symbol corresponding to the output
