| 835 | both USE_REL and USE_RELA ['twould be nice if such a critter existed], |
| 836 | if only to serve as a learning tool. |
| 837 | |
| 838 | The RELOCATE_SECTION function is called by the new ELF backend linker |
| 839 | to handle the relocations for a section. |
| 840 | |
| 841 | The relocs are always passed as Rela structures; if the section |
| 842 | actually uses Rel structures, the r_addend field will always be |
| 843 | zero. |
| 844 | |
| 845 | This function is responsible for adjusting the section contents as |
| 846 | necessary, and (if using Rela relocs and generating a relocateable |
| 847 | output file) adjusting the reloc addend as necessary. |
| 848 | |
| 849 | This function does not have to worry about setting the reloc |
| 850 | address or the reloc symbol index. |
| 851 | |
| 852 | LOCAL_SYMS is a pointer to the swapped in local symbols. |
| 853 | |
| 854 | LOCAL_SECTIONS is an array giving the section in the input file |
| 855 | corresponding to the st_shndx field of each local symbol. |
| 856 | |
| 857 | The global hash table entry for the global symbols can be found |
| 858 | via elf_sym_hashes (input_bfd). |
| 859 | |
| 860 | When generating relocateable output, this function must handle |
| 861 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is |
| 862 | going to be the section symbol corresponding to the output |
