2627
2628 This function is responsible for adjusting the section contents as
1049f94e 2629 necessary, and (if using Rela relocs and generating a relocatable
4e5ba5b7
DB		 2630 output file) adjusting the reloc addend as necessary.
2631
2632 This function does not have to worry about setting the reloc
2633 address or the reloc symbol index.
2634
2635 LOCAL_SYMS is a pointer to the swapped in local symbols.
2636
2637 LOCAL_SECTIONS is an array giving the section in the input file
2638 corresponding to the st_shndx field of each local symbol.
2639
2640 The global hash table entry for the global symbols can be found
2641 via elf_sym_hashes (input_bfd).
2642
1049f94e 2643 When generating relocatable output, this function must handle
4e5ba5b7
DB		 2644 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2645 going to be the section symbol corresponding to the output
2646 section, which means that the addend must be adjusted
2647 accordingly. */

51532845
AO		 5907
5908 Besides handling virtual table relocs for gc, we have to deal with
5909 all sorts of PIC-related relocations. We describe below the
5910 general plan on how to handle such relocations, even though we only
5911 collect information at this point, storing them in hash tables for
5912 perusal of later passes.
5913
5914 32 relocations are propagated to the linker output when creating
5915 position-independent output. LO16 and HI16 relocations are not
5916 supposed to be encountered in this case.
5917
5918 LABEL16 should always be resolvable by the linker, since it's only
5919 used by branches.
5920
5921 LABEL24, on the other hand, is used by calls. If it turns out that
5922 the target of a call is a dynamic symbol, a PLT entry must be
5923 created for it, which triggers the creation of a private function
5924 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5925
5926 GPREL relocations require the referenced symbol to be in the same
5927 segment as _gp, but this can only be checked later.
5928
5929 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5930 exist. LABEL24 might as well, since it may require a PLT entry,
5931 that will require a got.
5932
5933 Non-FUNCDESC GOT relocations require a GOT entry to be created
5934 regardless of whether the symbol is dynamic. However, since a
5935 global symbol that turns out to not be exported may have the same
5936 address of a non-dynamic symbol, we don't assign GOT entries at
5937 this point, such that we can share them in this case. A relocation
5938 for the GOT entry always has to be created, be it to offset a
5939 private symbol by the section load address, be it to get the symbol
5940 resolved dynamically.
5941
5942 FUNCDESC GOT relocations require a GOT entry to be created, and
5943 handled as if a FUNCDESC relocation was applied to the GOT entry in
5944 an object file.
5945
5946 FUNCDESC relocations referencing a symbol that turns out to NOT be
5947 dynamic cause a private function descriptor to be created. The
5948 FUNCDESC relocation then decays to a 32 relocation that points at
5949 the private descriptor. If the symbol is dynamic, the FUNCDESC
5950 relocation is propagated to the linker output, such that the
5951 dynamic linker creates the canonical descriptor, pointing to the
5952 dynamically-resolved definition of the function.
5953
5954 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
5955 symbols that are assigned to the same segment as the GOT, but we
5956 can only check this later, after we know the complete set of
5957 symbols defined and/or exported.
5958
5959 FUNCDESC GOTOFF relocations require a function descriptor to be
5960 created and, unless lazy binding is disabled or the symbol is not
5961 dynamic, a lazy PLT entry. Since we can't tell at this point
5962 whether a symbol is going to be dynamic, we have to decide later
5963 whether to create a lazy PLT entry or bind the descriptor directly
5964 to the private function.
5965
5966 FUNCDESC_VALUE relocations are not supposed to be present in object
5967 files, but they may very well be simply propagated to the linker
5968 output, since they have no side effect.
5969
5970
5971 A function descriptor always requires a FUNCDESC_VALUE relocation.
5972 Whether it's in .plt.rel or not depends on whether lazy binding is
5973 enabled and on whether the referenced symbol is dynamic.
5974
5975 The existence of a lazy PLT requires the resolverStub lazy PLT
5976 entry to be present.
5977
5978
5979 As for assignment of GOT, PLT and lazy PLT entries, and private
5980 descriptors, we might do them all sequentially, but we can do
5981 better than that. For example, we can place GOT entries and
5982 private function descriptors referenced using 12-bit operands
5983 closer to the PIC register value, such that these relocations don't
5984 overflow. Those that are only referenced with LO16 relocations
5985 could come next, but we may as well place PLT-required function
5986 descriptors in the 12-bit range to make them shorter. Symbols
5987 referenced with LO16/HI16 may come next, but we may place
5988 additional function descriptors in the 16-bit range if we can
5989 reliably tell that we've already placed entries that are ever
5990 referenced with only LO16. PLT entries are therefore generated as
5991 small as possible, while not introducing relocation overflows in
5992 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
5993 generated before or after PLT entries, but not intermingled with
5994 them, such that we can have more lazy PLT entries in range for a
5995 branch to the resolverStub. The resolverStub should be emitted at
5996 the most distant location from the first lazy PLT entry such that
5997 it's still in range for a branch, or closer, if there isn't a need
5998 for so many lazy PLT entries. Additional lazy PLT entries may be
5999 emitted after the resolverStub, as long as branches are still in
6000 range. If the branch goes out of range, longer lazy PLT entries
6001 are emitted.
6002
6003 We could further optimize PLT and lazy PLT entries by giving them
6004 priority in assignment to closer-to-gr17 locations depending on the
6005 number of occurrences of references to them (assuming a function
6006 that's called more often is more important for performance, so its
6007 PLT entry should be faster), or taking hints from the compiler.
6008 Given infinite time and money... :-) */
