2620 The RELOCATE_SECTION function is called by the new ELF backend linker

2623 The relocs are always passed as Rela structures; if the section

2625 zero.

4e5ba5b7

2634 LOCAL_SYMS is a pointer to the swapped in local symbols.
2635
2636 LOCAL_SECTIONS is an array giving the section in the input file
2637 corresponding to the st_shndx field of each local symbol.
2638
2639 The global hash table entry for the global symbols can be found
2640 via elf_sym_hashes (input_bfd).

4e5ba5b7
DB		 2643 STB_LOCAL/STT_SECTION symbols specially. The output symbol is

51532845
AO		 5910
5911 Besides handling virtual table relocs for gc, we have to deal with
5912 all sorts of PIC-related relocations. We describe below the
5913 general plan on how to handle such relocations, even though we only
5914 collect information at this point, storing them in hash tables for
5915 perusal of later passes.
5916
5917 32 relocations are propagated to the linker output when creating
5918 position-independent output. LO16 and HI16 relocations are not
5919 supposed to be encountered in this case.
5920
5921 LABEL16 should always be resolvable by the linker, since it's only
5922 used by branches.
5923
5924 LABEL24, on the other hand, is used by calls. If it turns out that
5925 the target of a call is a dynamic symbol, a PLT entry must be
5926 created for it, which triggers the creation of a private function
5927 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5928
5929 GPREL relocations require the referenced symbol to be in the same
5930 segment as _gp, but this can only be checked later.
5931
5932 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5933 exist. LABEL24 might as well, since it may require a PLT entry,
5934 that will require a got.
5935
5936 Non-FUNCDESC GOT relocations require a GOT entry to be created
5937 regardless of whether the symbol is dynamic. However, since a
5938 global symbol that turns out to not be exported may have the same
5939 address of a non-dynamic symbol, we don't assign GOT entries at
5940 this point, such that we can share them in this case. A relocation
5941 for the GOT entry always has to be created, be it to offset a
5942 private symbol by the section load address, be it to get the symbol
5943 resolved dynamically.
5944
5945 FUNCDESC GOT relocations require a GOT entry to be created, and
5946 handled as if a FUNCDESC relocation was applied to the GOT entry in
5947 an object file.
5948
5949 FUNCDESC relocations referencing a symbol that turns out to NOT be
5950 dynamic cause a private function descriptor to be created. The
5951 FUNCDESC relocation then decays to a 32 relocation that points at
5952 the private descriptor. If the symbol is dynamic, the FUNCDESC
5953 relocation is propagated to the linker output, such that the
5954 dynamic linker creates the canonical descriptor, pointing to the
5955 dynamically-resolved definition of the function.
5956
5957 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
5958 symbols that are assigned to the same segment as the GOT, but we
5959 can only check this later, after we know the complete set of
5960 symbols defined and/or exported.
5961
5962 FUNCDESC GOTOFF relocations require a function descriptor to be
5963 created and, unless lazy binding is disabled or the symbol is not
5964 dynamic, a lazy PLT entry. Since we can't tell at this point
5965 whether a symbol is going to be dynamic, we have to decide later
5966 whether to create a lazy PLT entry or bind the descriptor directly
5967 to the private function.
5968
5969 FUNCDESC_VALUE relocations are not supposed to be present in object
5970 files, but they may very well be simply propagated to the linker
5971 output, since they have no side effect.
5972
5973
5974 A function descriptor always requires a FUNCDESC_VALUE relocation.
5975 Whether it's in .plt.rel or not depends on whether lazy binding is
5976 enabled and on whether the referenced symbol is dynamic.
5977
5978 The existence of a lazy PLT requires the resolverStub lazy PLT
5979 entry to be present.
5980
5981
5982 As for assignment of GOT, PLT and lazy PLT entries, and private
5983 descriptors, we might do them all sequentially, but we can do
5984 better than that. For example, we can place GOT entries and
5985 private function descriptors referenced using 12-bit operands
5986 closer to the PIC register value, such that these relocations don't
5987 overflow. Those that are only referenced with LO16 relocations
5988 could come next, but we may as well place PLT-required function
5989 descriptors in the 12-bit range to make them shorter. Symbols
5990 referenced with LO16/HI16 may come next, but we may place
5991 additional function descriptors in the 16-bit range if we can
5992 reliably tell that we've already placed entries that are ever
5993 referenced with only LO16. PLT entries are therefore generated as
5994 small as possible, while not introducing relocation overflows in
5995 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
5996 generated before or after PLT entries, but not intermingled with
5997 them, such that we can have more lazy PLT entries in range for a
5998 branch to the resolverStub. The resolverStub should be emitted at
5999 the most distant location from the first lazy PLT entry such that
6000 it's still in range for a branch, or closer, if there isn't a need
6001 for so many lazy PLT entries. Additional lazy PLT entries may be
6002 emitted after the resolverStub, as long as branches are still in
6003 range. If the branch goes out of range, longer lazy PLT entries
6004 are emitted.
6005
6006 We could further optimize PLT and lazy PLT entries by giving them
6007 priority in assignment to closer-to-gr17 locations depending on the
6008 number of occurrences of references to them (assuming a function
6009 that's called more often is more important for performance, so its
6010 PLT entry should be faster), or taking hints from the compiler.
6011 Given infinite time and money... :-) */
