4e5ba5b7 DB |
2684 | |
2685 | The RELOCATE_SECTION function is called by the new ELF backend linker | |
2686 | to handle the relocations for a section. | |
2687 | ||
2688 | The relocs are always passed as Rela structures; if the section | |
2689 | actually uses Rel structures, the r_addend field will always be | |
2690 | zero. | |
2691 | ||
2692 | This function is responsible for adjusting the section contents as | |
1049f94e | 2693 | necessary, and (if using Rela relocs and generating a relocatable |
4e5ba5b7 DB |
2694 | output file) adjusting the reloc addend as necessary. |
2695 | ||
2696 | This function does not have to worry about setting the reloc | |
2697 | address or the reloc symbol index. | |
2698 | ||
2699 | LOCAL_SYMS is a pointer to the swapped in local symbols. | |
2700 | ||
2701 | LOCAL_SECTIONS is an array giving the section in the input file | |
2702 | corresponding to the st_shndx field of each local symbol. | |
2703 | ||
2704 | The global hash table entry for the global symbols can be found | |
2705 | via elf_sym_hashes (input_bfd). | |
2706 | ||
1049f94e | 2707 | When generating relocatable output, this function must handle |
4e5ba5b7 DB |
2708 | STB_LOCAL/STT_SECTION symbols specially. The output symbol is |
2709 | going to be the section symbol corresponding to the output | |
2710 | section, which means that the addend must be adjusted | |
2711 | accordingly. */ | |

6056 | 32 relocations are propagated to the linker output when creating | |
6057 | position-independent output. LO16 and HI16 relocations are not | |
6058 | supposed to be encountered in this case. | |
6059 | ||
6060 | LABEL16 should always be resolvable by the linker, since it's only | |
6061 | used by branches. | |
6062 | ||
6063 | LABEL24, on the other hand, is used by calls. If it turns out that | |
6064 | the target of a call is a dynamic symbol, a PLT entry must be | |
6065 | created for it, which triggers the creation of a private function | |
6066 | descriptor and, unless lazy binding is disabled, a lazy PLT entry. | |
6067 | ||
6068 | GPREL relocations require the referenced symbol to be in the same | |
6069 | segment as _gp, but this can only be checked later. | |
6070 | ||
6071 | All GOT, GOTOFF and FUNCDESC relocations require a .got section to | |
6072 | exist. LABEL24 might as well, since it may require a PLT entry, | |
6073 | that will require a got. | |
6074 | ||
6075 | Non-FUNCDESC GOT relocations require a GOT entry to be created | |
6076 | regardless of whether the symbol is dynamic. However, since a | |
6077 | global symbol that turns out to not be exported may have the same | |
6078 | address of a non-dynamic symbol, we don't assign GOT entries at | |
6079 | this point, such that we can share them in this case. A relocation | |
6080 | for the GOT entry always has to be created, be it to offset a | |
6081 | private symbol by the section load address, be it to get the symbol | |
6082 | resolved dynamically. | |
6083 | ||
6084 | FUNCDESC GOT relocations require a GOT entry to be created, and | |
6085 | handled as if a FUNCDESC relocation was applied to the GOT entry in | |
6086 | an object file. | |
6087 | ||
6088 | FUNCDESC relocations referencing a symbol that turns out to NOT be | |
6089 | dynamic cause a private function descriptor to be created. The | |
6090 | FUNCDESC relocation then decays to a 32 relocation that points at | |
6091 | the private descriptor. If the symbol is dynamic, the FUNCDESC | |
6092 | relocation is propagated to the linker output, such that the | |
6093 | dynamic linker creates the canonical descriptor, pointing to the | |
6094 | dynamically-resolved definition of the function. | |
6095 | ||
6096 | Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic | |
6097 | symbols that are assigned to the same segment as the GOT, but we | |
6098 | can only check this later, after we know the complete set of | |
6099 | symbols defined and/or exported. | |
6100 | ||
6101 | FUNCDESC GOTOFF relocations require a function descriptor to be | |
6102 | created and, unless lazy binding is disabled or the symbol is not | |
6103 | dynamic, a lazy PLT entry. Since we can't tell at this point | |
6104 | whether a symbol is going to be dynamic, we have to decide later | |
6105 | whether to create a lazy PLT entry or bind the descriptor directly | |
6106 | to the private function. | |
6107 | ||
6108 | FUNCDESC_VALUE relocations are not supposed to be present in object | |
6109 | files, but they may very well be simply propagated to the linker | |
6110 | output, since they have no side effect. | |
6111 | ||
6112 | ||
6113 | A function descriptor always requires a FUNCDESC_VALUE relocation. | |
6114 | Whether it's in .plt.rel or not depends on whether lazy binding is | |
6115 | enabled and on whether the referenced symbol is dynamic. | |
6116 | ||
6117 | The existence of a lazy PLT requires the resolverStub lazy PLT | |
6118 | entry to be present. | |
6119 | ||
6120 | ||
6121 | As for assignment of GOT, PLT and lazy PLT entries, and private | |
6122 | descriptors, we might do them all sequentially, but we can do | |
6123 | better than that. For example, we can place GOT entries and | |
6124 | private function descriptors referenced using 12-bit operands | |
6125 | closer to the PIC register value, such that these relocations don't | |
6126 | overflow. Those that are only referenced with LO16 relocations | |
6127 | could come next, but we may as well place PLT-required function | |
6128 | descriptors in the 12-bit range to make them shorter. Symbols | |
6129 | referenced with LO16/HI16 may come next, but we may place | |
6130 | additional function descriptors in the 16-bit range if we can | |
6131 | reliably tell that we've already placed entries that are ever | |
6132 | referenced with only LO16. PLT entries are therefore generated as | |
6133 | small as possible, while not introducing relocation overflows in | |
6134 | GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be | |
6135 | generated before or after PLT entries, but not intermingled with | |
6136 | them, such that we can have more lazy PLT entries in range for a | |
6137 | branch to the resolverStub. The resolverStub should be emitted at | |
6138 | the most distant location from the first lazy PLT entry such that | |
6139 | it's still in range for a branch, or closer, if there isn't a need | |
6140 | for so many lazy PLT entries. Additional lazy PLT entries may be | |
6141 | emitted after the resolverStub, as long as branches are still in | |
6142 | range. If the branch goes out of range, longer lazy PLT entries | |
6143 | are emitted. | |
6144 | ||
6145 | We could further optimize PLT and lazy PLT entries by giving them | |
6146 | priority in assignment to closer-to-gr17 locations depending on the | |
6147 | number of occurrences of references to them (assuming a function | |
6148 | that's called more often is more important for performance, so its | |
6149 | PLT entry should be faster), or taking hints from the compiler. | |
6150 | Given infinite time and money... :-) */ | |
