529 There is some attempt to make this function usable for many architectures,
530 both USE_REL and USE_RELA ['twould be nice if such a critter existed],
531 if only to serve as a learning tool.
533 The RELOCATE_SECTION function is called by the new ELF backend linker
534 to handle the relocations for a section.
536 The relocs are always passed as Rela structures; if the section

540 This function is responsible for adjusting the section contents as
541 necessary, and (if using Rela relocs and generating a relocatable
542 output file) adjusting the reloc addend as necessary.
544 This function does not have to worry about setting the reloc
545 address or the reloc symbol index.
547 LOCAL_SYMS is a pointer to the swapped in local symbols.
549 LOCAL_SECTIONS is an array giving the section in the input file
550 corresponding to the st_shndx field of each local symbol.
552 The global hash table entry for the global symbols can be found
553 via elf_sym_hashes (input_bfd).
555 When generating relocatable output, this function must handle
556 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
557 going to be the section symbol corresponding to the output
