2677 The RELOCATE_SECTION function is called by the new ELF backend linker
2678 to handle the relocations for a section.
2679
2680 The relocs are always passed as Rela structures; if the section
2681 actually uses Rel structures, the r_addend field will always be
2682 zero.
2683
2684 This function is responsible for adjusting the section contents as
1049f94e 2685 necessary, and (if using Rela relocs and generating a relocatable
4e5ba5b7
DB		 2686 output file) adjusting the reloc addend as necessary.
2687
2688 This function does not have to worry about setting the reloc
2689 address or the reloc symbol index.
2690
2691 LOCAL_SYMS is a pointer to the swapped in local symbols.
2692
2693 LOCAL_SECTIONS is an array giving the section in the input file
2694 corresponding to the st_shndx field of each local symbol.
2695
2696 The global hash table entry for the global symbols can be found
2697 via elf_sym_hashes (input_bfd).
2698
1049f94e 2699 When generating relocatable output, this function must handle
4e5ba5b7
DB		 2700 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2701 going to be the section symbol corresponding to the output
2702 section, which means that the addend must be adjusted
2703 accordingly. */

51532845
AO		 5972
5973 Besides handling virtual table relocs for gc, we have to deal with
5974 all sorts of PIC-related relocations. We describe below the
5975 general plan on how to handle such relocations, even though we only
5976 collect information at this point, storing them in hash tables for
5977 perusal of later passes.
5978
5979 32 relocations are propagated to the linker output when creating
5980 position-independent output. LO16 and HI16 relocations are not
5981 supposed to be encountered in this case.
5982
5983 LABEL16 should always be resolvable by the linker, since it's only
5984 used by branches.
5985
5986 LABEL24, on the other hand, is used by calls. If it turns out that
5987 the target of a call is a dynamic symbol, a PLT entry must be
5988 created for it, which triggers the creation of a private function
5989 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5990
5991 GPREL relocations require the referenced symbol to be in the same
5992 segment as _gp, but this can only be checked later.
5993
5994 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5995 exist. LABEL24 might as well, since it may require a PLT entry,
5996 that will require a got.
5997
5998 Non-FUNCDESC GOT relocations require a GOT entry to be created
5999 regardless of whether the symbol is dynamic. However, since a
6000 global symbol that turns out to not be exported may have the same
6001 address of a non-dynamic symbol, we don't assign GOT entries at
6002 this point, such that we can share them in this case. A relocation
6003 for the GOT entry always has to be created, be it to offset a
6004 private symbol by the section load address, be it to get the symbol
6005 resolved dynamically.
6006
6007 FUNCDESC GOT relocations require a GOT entry to be created, and
6008 handled as if a FUNCDESC relocation was applied to the GOT entry in
6009 an object file.
6010
6011 FUNCDESC relocations referencing a symbol that turns out to NOT be
6012 dynamic cause a private function descriptor to be created. The
6013 FUNCDESC relocation then decays to a 32 relocation that points at
6014 the private descriptor. If the symbol is dynamic, the FUNCDESC
6015 relocation is propagated to the linker output, such that the
6016 dynamic linker creates the canonical descriptor, pointing to the
6017 dynamically-resolved definition of the function.
6018
6019 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
6020 symbols that are assigned to the same segment as the GOT, but we
6021 can only check this later, after we know the complete set of
6022 symbols defined and/or exported.
6023
6024 FUNCDESC GOTOFF relocations require a function descriptor to be
6025 created and, unless lazy binding is disabled or the symbol is not
6026 dynamic, a lazy PLT entry. Since we can't tell at this point
6027 whether a symbol is going to be dynamic, we have to decide later
6028 whether to create a lazy PLT entry or bind the descriptor directly
6029 to the private function.
6030
6031 FUNCDESC_VALUE relocations are not supposed to be present in object
6032 files, but they may very well be simply propagated to the linker
6033 output, since they have no side effect.
6034
6035
6036 A function descriptor always requires a FUNCDESC_VALUE relocation.
6037 Whether it's in .plt.rel or not depends on whether lazy binding is
6038 enabled and on whether the referenced symbol is dynamic.
6039
6040 The existence of a lazy PLT requires the resolverStub lazy PLT
6041 entry to be present.
6042
6043
6044 As for assignment of GOT, PLT and lazy PLT entries, and private
6045 descriptors, we might do them all sequentially, but we can do
6046 better than that. For example, we can place GOT entries and
6047 private function descriptors referenced using 12-bit operands
6048 closer to the PIC register value, such that these relocations don't
6049 overflow. Those that are only referenced with LO16 relocations
6050 could come next, but we may as well place PLT-required function
6051 descriptors in the 12-bit range to make them shorter. Symbols
6052 referenced with LO16/HI16 may come next, but we may place
6053 additional function descriptors in the 16-bit range if we can
6054 reliably tell that we've already placed entries that are ever
6055 referenced with only LO16. PLT entries are therefore generated as
6056 small as possible, while not introducing relocation overflows in
6057 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6058 generated before or after PLT entries, but not intermingled with
6059 them, such that we can have more lazy PLT entries in range for a
6060 branch to the resolverStub. The resolverStub should be emitted at
6061 the most distant location from the first lazy PLT entry such that
6062 it's still in range for a branch, or closer, if there isn't a need
6063 for so many lazy PLT entries. Additional lazy PLT entries may be
6064 emitted after the resolverStub, as long as branches are still in
6065 range. If the branch goes out of range, longer lazy PLT entries
6066 are emitted.
6067
6068 We could further optimize PLT and lazy PLT entries by giving them
6069 priority in assignment to closer-to-gr17 locations depending on the
6070 number of occurrences of references to them (assuming a function
6071 that's called more often is more important for performance, so its
6072 PLT entry should be faster), or taking hints from the compiler.
6073 Given infinite time and money... :-) */
