2698 The RELOCATE_SECTION function is called by the new ELF backend linker
2699 to handle the relocations for a section.
2700
2701 The relocs are always passed as Rela structures; if the section
2702 actually uses Rel structures, the r_addend field will always be
2703 zero.
2704
2705 This function is responsible for adjusting the section contents as
1049f94e 2706 necessary, and (if using Rela relocs and generating a relocatable
4e5ba5b7
DB
2707 output file) adjusting the reloc addend as necessary.
2708
2709 This function does not have to worry about setting the reloc
2710 address or the reloc symbol index.
2711
2712 LOCAL_SYMS is a pointer to the swapped in local symbols.
2713
2714 LOCAL_SECTIONS is an array giving the section in the input file
2715 corresponding to the st_shndx field of each local symbol.
2716
2717 The global hash table entry for the global symbols can be found
2718 via elf_sym_hashes (input_bfd).
2719
1049f94e 2720 When generating relocatable output, this function must handle
4e5ba5b7
DB
2721 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2722 going to be the section symbol corresponding to the output
2723 section, which means that the addend must be adjusted
2724 accordingly. */

6068
6069 Besides handling virtual table relocs for gc, we have to deal with
6070 all sorts of PIC-related relocations. We describe below the
6071 general plan on how to handle such relocations, even though we only
6072 collect information at this point, storing them in hash tables for
6073 perusal of later passes.
6074
6075 32 relocations are propagated to the linker output when creating
6076 position-independent output. LO16 and HI16 relocations are not
6077 supposed to be encountered in this case.
6078
6079 LABEL16 should always be resolvable by the linker, since it's only
6080 used by branches.
6081
6082 LABEL24, on the other hand, is used by calls. If it turns out that
6083 the target of a call is a dynamic symbol, a PLT entry must be
6084 created for it, which triggers the creation of a private function
6085 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
6086
6087 GPREL relocations require the referenced symbol to be in the same
6088 segment as _gp, but this can only be checked later.
6089
6090 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
6091 exist. LABEL24 might as well, since it may require a PLT entry,
6092 that will require a got.
6093
6094 Non-FUNCDESC GOT relocations require a GOT entry to be created
6095 regardless of whether the symbol is dynamic. However, since a
6096 global symbol that turns out to not be exported may have the same
6097 address of a non-dynamic symbol, we don't assign GOT entries at
6098 this point, such that we can share them in this case. A relocation
6099 for the GOT entry always has to be created, be it to offset a
6100 private symbol by the section load address, be it to get the symbol
6101 resolved dynamically.
6102
6103 FUNCDESC GOT relocations require a GOT entry to be created, and
6104 handled as if a FUNCDESC relocation was applied to the GOT entry in
6105 an object file.
6106
6107 FUNCDESC relocations referencing a symbol that turns out to NOT be
6108 dynamic cause a private function descriptor to be created. The
6109 FUNCDESC relocation then decays to a 32 relocation that points at
6110 the private descriptor. If the symbol is dynamic, the FUNCDESC
6111 relocation is propagated to the linker output, such that the
6112 dynamic linker creates the canonical descriptor, pointing to the
6113 dynamically-resolved definition of the function.
6114
6115 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
6116 symbols that are assigned to the same segment as the GOT, but we
6117 can only check this later, after we know the complete set of
6118 symbols defined and/or exported.
6119
6120 FUNCDESC GOTOFF relocations require a function descriptor to be
6121 created and, unless lazy binding is disabled or the symbol is not
6122 dynamic, a lazy PLT entry. Since we can't tell at this point
6123 whether a symbol is going to be dynamic, we have to decide later
6124 whether to create a lazy PLT entry or bind the descriptor directly
6125 to the private function.
6126
6127 FUNCDESC_VALUE relocations are not supposed to be present in object
6128 files, but they may very well be simply propagated to the linker
6129 output, since they have no side effect.
6130
6131
6132 A function descriptor always requires a FUNCDESC_VALUE relocation.
6133 Whether it's in .plt.rel or not depends on whether lazy binding is
6134 enabled and on whether the referenced symbol is dynamic.
6135
6136 The existence of a lazy PLT requires the resolverStub lazy PLT
6137 entry to be present.
6138
6139
6140 As for assignment of GOT, PLT and lazy PLT entries, and private
6141 descriptors, we might do them all sequentially, but we can do
6142 better than that. For example, we can place GOT entries and
6143 private function descriptors referenced using 12-bit operands
6144 closer to the PIC register value, such that these relocations don't
6145 overflow. Those that are only referenced with LO16 relocations
6146 could come next, but we may as well place PLT-required function
6147 descriptors in the 12-bit range to make them shorter. Symbols
6148 referenced with LO16/HI16 may come next, but we may place
6149 additional function descriptors in the 16-bit range if we can
6150 reliably tell that we've already placed entries that are ever
6151 referenced with only LO16. PLT entries are therefore generated as
6152 small as possible, while not introducing relocation overflows in
6153 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6154 generated before or after PLT entries, but not intermingled with
6155 them, such that we can have more lazy PLT entries in range for a
6156 branch to the resolverStub. The resolverStub should be emitted at
6157 the most distant location from the first lazy PLT entry such that
6158 it's still in range for a branch, or closer, if there isn't a need
6159 for so many lazy PLT entries. Additional lazy PLT entries may be
6160 emitted after the resolverStub, as long as branches are still in
6161 range. If the branch goes out of range, longer lazy PLT entries
6162 are emitted.
6163
6164 We could further optimize PLT and lazy PLT entries by giving them
6165 priority in assignment to closer-to-gr17 locations depending on the
6166 number of occurrences of references to them (assuming a function
6167 that's called more often is more important for performance, so its
6168 PLT entry should be faster), or taking hints from the compiler.
6169 Given infinite time and money... :-) */
