5919 /* Look through the relocs for a section during the first phase.
5921 Besides handling virtual table relocs for gc, we have to deal with
5922 all sorts of PIC-related relocations. We describe below the
5923 general plan on how to handle such relocations, even though we only
5924 collect information at this point, storing them in hash tables for
5925 perusal of later passes.
5927 32 relocations are propagated to the linker output when creating
5928 position-independent output. LO16 and HI16 relocations are not
5929 supposed to be encountered in this case.
5931 LABEL16 should always be resolvable by the linker, since it's only
5934 LABEL24, on the other hand, is used by calls. If it turns out that
5935 the target of a call is a dynamic symbol, a PLT entry must be
5936 created for it, which triggers the creation of a private function
5937 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5939 GPREL relocations require the referenced symbol to be in the same
5940 segment as _gp, but this can only be checked later.
5942 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5943 exist. LABEL24 might as well, since it may require a PLT entry,
5944 that will require a got.
5946 Non-FUNCDESC GOT relocations require a GOT entry to be created
5947 regardless of whether the symbol is dynamic. However, since a
5948 global symbol that turns out to not be exported may have the same
5949 address of a non-dynamic symbol, we don't assign GOT entries at
5950 this point, such that we can share them in this case. A relocation
5951 for the GOT entry always has to be created, be it to offset a
5952 private symbol by the section load address, be it to get the symbol
5953 resolved dynamically.
5955 FUNCDESC GOT relocations require a GOT entry to be created, and
5956 handled as if a FUNCDESC relocation was applied to the GOT entry in
5959 FUNCDESC relocations referencing a symbol that turns out to NOT be
5960 dynamic cause a private function descriptor to be created. The
5961 FUNCDESC relocation then decays to a 32 relocation that points at
5962 the private descriptor. If the symbol is dynamic, the FUNCDESC
5963 relocation is propagated to the linker output, such that the
5964 dynamic linker creates the canonical descriptor, pointing to the
5965 dynamically-resolved definition of the function.
5967 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
5968 symbols that are assigned to the same segment as the GOT, but we
5969 can only check this later, after we know the complete set of
5970 symbols defined and/or exported.
5972 FUNCDESC GOTOFF relocations require a function descriptor to be
5973 created and, unless lazy binding is disabled or the symbol is not
5974 dynamic, a lazy PLT entry. Since we can't tell at this point
5975 whether a symbol is going to be dynamic, we have to decide later
5976 whether to create a lazy PLT entry or bind the descriptor directly
5977 to the private function.
5979 FUNCDESC_VALUE relocations are not supposed to be present in object
5980 files, but they may very well be simply propagated to the linker
5981 output, since they have no side effect.
5984 A function descriptor always requires a FUNCDESC_VALUE relocation.
5985 Whether it's in .plt.rel or not depends on whether lazy binding is
5986 enabled and on whether the referenced symbol is dynamic.
5988 The existence of a lazy PLT requires the resolverStub lazy PLT
5989 entry to be present.
5992 As for assignment of GOT, PLT and lazy PLT entries, and private
5993 descriptors, we might do them all sequentially, but we can do
5994 better than that. For example, we can place GOT entries and
5995 private function descriptors referenced using 12-bit operands
5996 closer to the PIC register value, such that these relocations don't
5997 overflow. Those that are only referenced with LO16 relocations
5998 could come next, but we may as well place PLT-required function
5999 descriptors in the 12-bit range to make them shorter. Symbols
6000 referenced with LO16/HI16 may come next, but we may place
6001 additional function descriptors in the 16-bit range if we can
6002 reliably tell that we've already placed entries that are ever
6003 referenced with only LO16. PLT entries are therefore generated as
6004 small as possible, while not introducing relocation overflows in
6005 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6006 generated before or after PLT entries, but not intermingled with
6007 them, such that we can have more lazy PLT entries in range for a
6008 branch to the resolverStub. The resolverStub should be emitted at
6009 the most distant location from the first lazy PLT entry such that
6010 it's still in range for a branch, or closer, if there isn't a need
6011 for so many lazy PLT entries. Additional lazy PLT entries may be
6012 emitted after the resolverStub, as long as branches are still in
6013 range. If the branch goes out of range, longer lazy PLT entries
6016 We could further optimize PLT and lazy PLT entries by giving them
6017 priority in assignment to closer-to-gr17 locations depending on the
6018 number of occurrences of references to them (assuming a function
6019 that's called more often is more important for performance, so its
6020 PLT entry should be faster), or taking hints from the compiler.
