534 There is some attempt to make this function usable for many architectures,

536 if only to serve as a learning tool.
538 The RELOCATE_SECTION function is called by the new ELF backend linker
539 to handle the relocations for a section.
541 The relocs are always passed as Rela structures; if the section

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