2624/* Relocate an FRV ELF section.
4e5ba5b7
DB		 2625
2626 The RELOCATE_SECTION function is called by the new ELF backend linker
2627 to handle the relocations for a section.
2628
2629 The relocs are always passed as Rela structures; if the section
2630 actually uses Rel structures, the r_addend field will always be
2631 zero.
2632
2633 This function is responsible for adjusting the section contents as
1049f94e 2634 necessary, and (if using Rela relocs and generating a relocatable
4e5ba5b7
DB		 2635 output file) adjusting the reloc addend as necessary.
2636
2637 This function does not have to worry about setting the reloc
2638 address or the reloc symbol index.
2639
2640 LOCAL_SYMS is a pointer to the swapped in local symbols.
2641
2642 LOCAL_SECTIONS is an array giving the section in the input file
2643 corresponding to the st_shndx field of each local symbol.
2644
2645 The global hash table entry for the global symbols can be found
2646 via elf_sym_hashes (input_bfd).
2647
1049f94e 2648 When generating relocatable output, this function must handle
4e5ba5b7
DB		 2649 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2650 going to be the section symbol corresponding to the output
2651 section, which means that the addend must be adjusted
2652 accordingly. */

51532845
AO		 5912
5913 Besides handling virtual table relocs for gc, we have to deal with
5914 all sorts of PIC-related relocations. We describe below the
5915 general plan on how to handle such relocations, even though we only
5916 collect information at this point, storing them in hash tables for
5917 perusal of later passes.
5918
5919 32 relocations are propagated to the linker output when creating
5920 position-independent output. LO16 and HI16 relocations are not
5921 supposed to be encountered in this case.
5922
5923 LABEL16 should always be resolvable by the linker, since it's only
5924 used by branches.
5925
5926 LABEL24, on the other hand, is used by calls. If it turns out that
5927 the target of a call is a dynamic symbol, a PLT entry must be
5928 created for it, which triggers the creation of a private function
5929 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5930
5931 GPREL relocations require the referenced symbol to be in the same
5932 segment as _gp, but this can only be checked later.
5933
5934 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5935 exist. LABEL24 might as well, since it may require a PLT entry,
5936 that will require a got.
5937
5938 Non-FUNCDESC GOT relocations require a GOT entry to be created
5939 regardless of whether the symbol is dynamic. However, since a
5940 global symbol that turns out to not be exported may have the same
5941 address of a non-dynamic symbol, we don't assign GOT entries at
5942 this point, such that we can share them in this case. A relocation
5943 for the GOT entry always has to be created, be it to offset a
5944 private symbol by the section load address, be it to get the symbol
5945 resolved dynamically.
5946
5947 FUNCDESC GOT relocations require a GOT entry to be created, and
5948 handled as if a FUNCDESC relocation was applied to the GOT entry in
5949 an object file.
5950
5951 FUNCDESC relocations referencing a symbol that turns out to NOT be
5952 dynamic cause a private function descriptor to be created. The
5953 FUNCDESC relocation then decays to a 32 relocation that points at
5954 the private descriptor. If the symbol is dynamic, the FUNCDESC
5955 relocation is propagated to the linker output, such that the
5956 dynamic linker creates the canonical descriptor, pointing to the
5957 dynamically-resolved definition of the function.
5958
5959 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
5960 symbols that are assigned to the same segment as the GOT, but we
5961 can only check this later, after we know the complete set of
5962 symbols defined and/or exported.
5963
5964 FUNCDESC GOTOFF relocations require a function descriptor to be
5965 created and, unless lazy binding is disabled or the symbol is not
5966 dynamic, a lazy PLT entry. Since we can't tell at this point
5967 whether a symbol is going to be dynamic, we have to decide later
5968 whether to create a lazy PLT entry or bind the descriptor directly
5969 to the private function.
5970
5971 FUNCDESC_VALUE relocations are not supposed to be present in object
5972 files, but they may very well be simply propagated to the linker
5973 output, since they have no side effect.
5974
5975
5976 A function descriptor always requires a FUNCDESC_VALUE relocation.
5977 Whether it's in .plt.rel or not depends on whether lazy binding is
5978 enabled and on whether the referenced symbol is dynamic.
5979
5980 The existence of a lazy PLT requires the resolverStub lazy PLT
5981 entry to be present.
5982
5983
5984 As for assignment of GOT, PLT and lazy PLT entries, and private
5985 descriptors, we might do them all sequentially, but we can do
5986 better than that. For example, we can place GOT entries and
5987 private function descriptors referenced using 12-bit operands
5988 closer to the PIC register value, such that these relocations don't
5989 overflow. Those that are only referenced with LO16 relocations
5990 could come next, but we may as well place PLT-required function
5991 descriptors in the 12-bit range to make them shorter. Symbols
5992 referenced with LO16/HI16 may come next, but we may place
5993 additional function descriptors in the 16-bit range if we can
5994 reliably tell that we've already placed entries that are ever
5995 referenced with only LO16. PLT entries are therefore generated as
5996 small as possible, while not introducing relocation overflows in
5997 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
5998 generated before or after PLT entries, but not intermingled with
5999 them, such that we can have more lazy PLT entries in range for a
6000 branch to the resolverStub. The resolverStub should be emitted at
6001 the most distant location from the first lazy PLT entry such that
6002 it's still in range for a branch, or closer, if there isn't a need
6003 for so many lazy PLT entries. Additional lazy PLT entries may be
6004 emitted after the resolverStub, as long as branches are still in
6005 range. If the branch goes out of range, longer lazy PLT entries
6006 are emitted.
6007
6008 We could further optimize PLT and lazy PLT entries by giving them
6009 priority in assignment to closer-to-gr17 locations depending on the
6010 number of occurrences of references to them (assuming a function
6011 that's called more often is more important for performance, so its
6012 PLT entry should be faster), or taking hints from the compiler.
6013 Given infinite time and money... :-) */
