5902 /* Look through the relocs for a section during the first phase.
5904 Besides handling virtual table relocs for gc, we have to deal with
5905 all sorts of PIC-related relocations. We describe below the
5906 general plan on how to handle such relocations, even though we only
5907 collect information at this point, storing them in hash tables for
5908 perusal of later passes.
5910 32 relocations are propagated to the linker output when creating
5911 position-independent output. LO16 and HI16 relocations are not
5912 supposed to be encountered in this case.
5914 LABEL16 should always be resolvable by the linker, since it's only
5917 LABEL24, on the other hand, is used by calls. If it turns out that
5918 the target of a call is a dynamic symbol, a PLT entry must be
5919 created for it, which triggers the creation of a private function
5920 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5922 GPREL relocations require the referenced symbol to be in the same
5923 segment as _gp, but this can only be checked later.
5925 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5926 exist. LABEL24 might as well, since it may require a PLT entry,
5927 that will require a got.
5929 Non-FUNCDESC GOT relocations require a GOT entry to be created
5930 regardless of whether the symbol is dynamic. However, since a
5931 global symbol that turns out to not be exported may have the same
5932 address of a non-dynamic symbol, we don't assign GOT entries at
5933 this point, such that we can share them in this case. A relocation
5934 for the GOT entry always has to be created, be it to offset a
5935 private symbol by the section load address, be it to get the symbol
5936 resolved dynamically.
5938 FUNCDESC GOT relocations require a GOT entry to be created, and
5939 handled as if a FUNCDESC relocation was applied to the GOT entry in
5942 FUNCDESC relocations referencing a symbol that turns out to NOT be
5943 dynamic cause a private function descriptor to be created. The
5944 FUNCDESC relocation then decays to a 32 relocation that points at
5945 the private descriptor. If the symbol is dynamic, the FUNCDESC
5946 relocation is propagated to the linker output, such that the
5947 dynamic linker creates the canonical descriptor, pointing to the
5948 dynamically-resolved definition of the function.
5950 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
5951 symbols that are assigned to the same segment as the GOT, but we
5952 can only check this later, after we know the complete set of
5953 symbols defined and/or exported.
5955 FUNCDESC GOTOFF relocations require a function descriptor to be
5956 created and, unless lazy binding is disabled or the symbol is not
5957 dynamic, a lazy PLT entry. Since we can't tell at this point
5958 whether a symbol is going to be dynamic, we have to decide later
5959 whether to create a lazy PLT entry or bind the descriptor directly
5960 to the private function.
5962 FUNCDESC_VALUE relocations are not supposed to be present in object
5963 files, but they may very well be simply propagated to the linker
5964 output, since they have no side effect.
5967 A function descriptor always requires a FUNCDESC_VALUE relocation.
5968 Whether it's in .plt.rel or not depends on whether lazy binding is
5969 enabled and on whether the referenced symbol is dynamic.
5971 The existence of a lazy PLT requires the resolverStub lazy PLT
5972 entry to be present.
5975 As for assignment of GOT, PLT and lazy PLT entries, and private
5976 descriptors, we might do them all sequentially, but we can do
5977 better than that. For example, we can place GOT entries and
5978 private function descriptors referenced using 12-bit operands
5979 closer to the PIC register value, such that these relocations don't
5980 overflow. Those that are only referenced with LO16 relocations
5981 could come next, but we may as well place PLT-required function
5982 descriptors in the 12-bit range to make them shorter. Symbols
5983 referenced with LO16/HI16 may come next, but we may place
5984 additional function descriptors in the 16-bit range if we can
5985 reliably tell that we've already placed entries that are ever
5986 referenced with only LO16. PLT entries are therefore generated as
5987 small as possible, while not introducing relocation overflows in
5988 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
5989 generated before or after PLT entries, but not intermingled with
5990 them, such that we can have more lazy PLT entries in range for a
5991 branch to the resolverStub. The resolverStub should be emitted at
5992 the most distant location from the first lazy PLT entry such that
5993 it's still in range for a branch, or closer, if there isn't a need
5994 for so many lazy PLT entries. Additional lazy PLT entries may be
5995 emitted after the resolverStub, as long as branches are still in
5996 range. If the branch goes out of range, longer lazy PLT entries
5999 We could further optimize PLT and lazy PLT entries by giving them
6000 priority in assignment to closer-to-gr17 locations depending on the
6001 number of occurrences of references to them (assuming a function
6002 that's called more often is more important for performance, so its
6003 PLT entry should be faster), or taking hints from the compiler.
