2682 | to handle the relocations for a section. | |
2683 | ||
2684 | The relocs are always passed as Rela structures; if the section | |
2685 | actually uses Rel structures, the r_addend field will always be | |
2686 | zero. | |
2687 | ||
2688 | This function is responsible for adjusting the section contents as | |
1049f94e | 2689 | necessary, and (if using Rela relocs and generating a relocatable |
4e5ba5b7 DB |
2690 | output file) adjusting the reloc addend as necessary. |
2691 | ||
2692 | This function does not have to worry about setting the reloc | |
2693 | address or the reloc symbol index. | |
2694 | ||
2695 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
2696 | ||
2697 | LOCAL_SECTIONS is an array giving the section in the input file | |
2698 | corresponding to the st_shndx field of each local symbol. | |
2699 | ||
2700 | The global hash table entry for the global symbols can be found | |
2701 | via elf_sym_hashes (input_bfd). | |
2702 | ||
1049f94e | 2703 | When generating relocatable output, this function must handle |
4e5ba5b7 DB |
2704 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is |
2705 | going to be the section symbol corresponding to the output | |
2706 | section, which means that the addend must be adjusted | |
2707 | accordingly. */ | |

51532845 AO |
5980 | |
5981 | Besides handling virtual table relocs for gc, we have to deal with | |
5982 | all sorts of PIC-related relocations. We describe below the | |
5983 | general plan on how to handle such relocations, even though we only | |
5984 | collect information at this point, storing them in hash tables for | |
5985 | perusal of later passes. | |
5986 | ||
5987 | 32 relocations are propagated to the linker output when creating | |
5988 | position-independent output. LO16 and HI16 relocations are not | |
5989 | supposed to be encountered in this case. | |
5990 | ||
5991 | LABEL16 should always be resolvable by the linker, since it's only | |
5992 | used by branches. | |
5993 | ||
5994 | LABEL24, on the other hand, is used by calls. If it turns out that | |
5995 | the target of a call is a dynamic symbol, a PLT entry must be | |
5996 | created for it, which triggers the creation of a private function | |
5997 | descriptor and, unless lazy binding is disabled, a lazy PLT entry. | |
5998 | ||
5999 | GPREL relocations require the referenced symbol to be in the same | |
6000 | segment as _gp, but this can only be checked later. | |
6001 | ||
6002 | All GOT, GOTOFF and FUNCDESC relocations require a .got section to | |
6003 | exist. LABEL24 might as well, since it may require a PLT entry, | |
6004 | that will require a got. | |
6005 | ||
6006 | Non-FUNCDESC GOT relocations require a GOT entry to be created | |
6007 | regardless of whether the symbol is dynamic. However, since a | |
6008 | global symbol that turns out to not be exported may have the same | |
6009 | address of a non-dynamic symbol, we don't assign GOT entries at | |
6010 | this point, such that we can share them in this case. A relocation | |
6011 | for the GOT entry always has to be created, be it to offset a | |
6012 | private symbol by the section load address, be it to get the symbol | |
6013 | resolved dynamically. | |
6014 | ||
6015 | FUNCDESC GOT relocations require a GOT entry to be created, and | |
6016 | handled as if a FUNCDESC relocation was applied to the GOT entry in | |
6017 | an object file. | |
6018 | ||
6019 | FUNCDESC relocations referencing a symbol that turns out to NOT be | |
6020 | dynamic cause a private function descriptor to be created. The | |
6021 | FUNCDESC relocation then decays to a 32 relocation that points at | |
6022 | the private descriptor. If the symbol is dynamic, the FUNCDESC | |
6023 | relocation is propagated to the linker output, such that the | |
6024 | dynamic linker creates the canonical descriptor, pointing to the | |
6025 | dynamically-resolved definition of the function. | |
6026 | ||
6027 | Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic | |
6028 | symbols that are assigned to the same segment as the GOT, but we | |
6029 | can only check this later, after we know the complete set of | |
6030 | symbols defined and/or exported. | |
6031 | ||
6032 | FUNCDESC GOTOFF relocations require a function descriptor to be | |
6033 | created and, unless lazy binding is disabled or the symbol is not | |
6034 | dynamic, a lazy PLT entry. Since we can't tell at this point | |
6035 | whether a symbol is going to be dynamic, we have to decide later | |
6036 | whether to create a lazy PLT entry or bind the descriptor directly | |
6037 | to the private function. | |
6038 | ||
6039 | FUNCDESC_VALUE relocations are not supposed to be present in object | |
6040 | files, but they may very well be simply propagated to the linker | |
6041 | output, since they have no side effect. | |
6042 | ||
6043 | ||
6044 | A function descriptor always requires a FUNCDESC_VALUE relocation. | |
6045 | Whether it's in .plt.rel or not depends on whether lazy binding is | |
6046 | enabled and on whether the referenced symbol is dynamic. | |
6047 | ||
6048 | The existence of a lazy PLT requires the resolverStub lazy PLT | |
6049 | entry to be present. | |
6050 | ||
6051 | ||
6052 | As for assignment of GOT, PLT and lazy PLT entries, and private | |
6053 | descriptors, we might do them all sequentially, but we can do | |
6054 | better than that. For example, we can place GOT entries and | |
6055 | private function descriptors referenced using 12-bit operands | |
6056 | closer to the PIC register value, such that these relocations don't | |
6057 | overflow. Those that are only referenced with LO16 relocations | |
6058 | could come next, but we may as well place PLT-required function | |
6059 | descriptors in the 12-bit range to make them shorter. Symbols | |
6060 | referenced with LO16/HI16 may come next, but we may place | |
6061 | additional function descriptors in the 16-bit range if we can | |
6062 | reliably tell that we've already placed entries that are ever | |
6063 | referenced with only LO16. PLT entries are therefore generated as | |
6064 | small as possible, while not introducing relocation overflows in | |
6065 | GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be | |
6066 | generated before or after PLT entries, but not intermingled with | |
6067 | them, such that we can have more lazy PLT entries in range for a | |
6068 | branch to the resolverStub. The resolverStub should be emitted at | |
6069 | the most distant location from the first lazy PLT entry such that | |
6070 | it's still in range for a branch, or closer, if there isn't a need | |
6071 | for so many lazy PLT entries. Additional lazy PLT entries may be | |
6072 | emitted after the resolverStub, as long as branches are still in | |
6073 | range. If the branch goes out of range, longer lazy PLT entries | |
6074 | are emitted. | |
6075 | ||
6076 | We could further optimize PLT and lazy PLT entries by giving them | |
6077 | priority in assignment to closer-to-gr17 locations depending on the | |
6078 | number of occurrences of references to them (assuming a function | |
6079 | that's called more often is more important for performance, so its | |
6080 | PLT entry should be faster), or taking hints from the compiler. | |
6081 | Given infinite time and money... :-) */ | |
