462 | /* Relocate an RX ELF section. | |
463 | There is some attempt to make this function usable for many architectures, | |
464 | both USE_REL and USE_RELA ['twould be nice if such a critter existed], | |
465 | if only to serve as a learning tool. | |
466 | ||
467 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
468 | to handle the relocations for a section. | |
469 | ||
470 | The relocs are always passed as Rela structures; if the section | |
471 | actually uses Rel structures, the r_addend field will always be | |
472 | zero. | |
473 | ||
474 | This function is responsible for adjusting the section contents as | |
475 | necessary, and (if using Rela relocs and generating a relocatable | |
476 | output file) adjusting the reloc addend as necessary. | |
477 | ||
478 | This function does not have to worry about setting the reloc | |
479 | address or the reloc symbol index. | |
480 | ||
481 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
482 | ||
483 | LOCAL_SECTIONS is an array giving the section in the input file | |
484 | corresponding to the st_shndx field of each local symbol. | |
485 | ||
486 | The global hash table entry for the global symbols can be found | |
487 | via elf_sym_hashes (input_bfd). | |
488 | ||
489 | When generating relocatable output, this function must handle | |
490 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is | |
491 | going to be the section symbol corresponding to the output | |
492 | section, which means that the addend must be adjusted | |
493 | accordingly. */ | |
