808 | This is boiler-plate code copied from fr30. |
809 | There is some attempt to make this function usable for many architectures, | |
810 | both USE_REL and USE_RELA ['twould be nice if such a critter existed], | |
811 | if only to serve as a learning tool. | |
812 | ||
813 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
814 | to handle the relocations for a section. | |
815 | ||
816 | The relocs are always passed as Rela structures; if the section | |
817 | actually uses Rel structures, the r_addend field will always be | |
818 | zero. | |
819 | ||
820 | This function is responsible for adjusting the section contents as | |
821 | necessary, and (if using Rela relocs and generating a relocateable | |
822 | output file) adjusting the reloc addend as necessary. | |
823 | ||
824 | This function does not have to worry about setting the reloc | |
825 | address or the reloc symbol index. | |
826 | ||
827 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
828 | ||
829 | LOCAL_SECTIONS is an array giving the section in the input file | |
830 | corresponding to the st_shndx field of each local symbol. | |
831 | ||
832 | The global hash table entry for the global symbols can be found | |
833 | via elf_sym_hashes (input_bfd). | |
834 | ||
835 | When generating relocateable output, this function must handle | |
836 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is | |
837 | going to be the section symbol corresponding to the output | |
838 | section, which means that the addend must be adjusted | |
