5971 Besides handling virtual table relocs for gc, we have to deal with
5972 all sorts of PIC-related relocations. We describe below the
5973 general plan on how to handle such relocations, even though we only
5974 collect information at this point, storing them in hash tables for
5975 perusal of later passes.
5977 32 relocations are propagated to the linker output when creating
5978 position-independent output. LO16 and HI16 relocations are not
5979 supposed to be encountered in this case.
5981 LABEL16 should always be resolvable by the linker, since it's only
5984 LABEL24, on the other hand, is used by calls. If it turns out that
5985 the target of a call is a dynamic symbol, a PLT entry must be
5986 created for it, which triggers the creation of a private function
5987 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
5989 GPREL relocations require the referenced symbol to be in the same
5990 segment as _gp, but this can only be checked later.
5992 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
5993 exist. LABEL24 might as well, since it may require a PLT entry,
5994 that will require a got.
5996 Non-FUNCDESC GOT relocations require a GOT entry to be created
5997 regardless of whether the symbol is dynamic. However, since a
5998 global symbol that turns out to not be exported may have the same
5999 address of a non-dynamic symbol, we don't assign GOT entries at
6000 this point, such that we can share them in this case. A relocation
6001 for the GOT entry always has to be created, be it to offset a
6002 private symbol by the section load address, be it to get the symbol
6003 resolved dynamically.
6005 FUNCDESC GOT relocations require a GOT entry to be created, and
6006 handled as if a FUNCDESC relocation was applied to the GOT entry in
6009 FUNCDESC relocations referencing a symbol that turns out to NOT be
6010 dynamic cause a private function descriptor to be created. The
6011 FUNCDESC relocation then decays to a 32 relocation that points at
6012 the private descriptor. If the symbol is dynamic, the FUNCDESC
6013 relocation is propagated to the linker output, such that the
6014 dynamic linker creates the canonical descriptor, pointing to the
6015 dynamically-resolved definition of the function.
6017 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
6018 symbols that are assigned to the same segment as the GOT, but we
6019 can only check this later, after we know the complete set of
6020 symbols defined and/or exported.
6022 FUNCDESC GOTOFF relocations require a function descriptor to be
6023 created and, unless lazy binding is disabled or the symbol is not
6024 dynamic, a lazy PLT entry. Since we can't tell at this point
6025 whether a symbol is going to be dynamic, we have to decide later
6026 whether to create a lazy PLT entry or bind the descriptor directly
6027 to the private function.
6029 FUNCDESC_VALUE relocations are not supposed to be present in object
6030 files, but they may very well be simply propagated to the linker
6031 output, since they have no side effect.
6034 A function descriptor always requires a FUNCDESC_VALUE relocation.
6035 Whether it's in .plt.rel or not depends on whether lazy binding is
6036 enabled and on whether the referenced symbol is dynamic.
6038 The existence of a lazy PLT requires the resolverStub lazy PLT
6039 entry to be present.
6042 As for assignment of GOT, PLT and lazy PLT entries, and private
6043 descriptors, we might do them all sequentially, but we can do
6044 better than that. For example, we can place GOT entries and
6045 private function descriptors referenced using 12-bit operands
6046 closer to the PIC register value, such that these relocations don't
6047 overflow. Those that are only referenced with LO16 relocations
6048 could come next, but we may as well place PLT-required function
6049 descriptors in the 12-bit range to make them shorter. Symbols
6050 referenced with LO16/HI16 may come next, but we may place
6051 additional function descriptors in the 16-bit range if we can
6052 reliably tell that we've already placed entries that are ever
6053 referenced with only LO16. PLT entries are therefore generated as
6054 small as possible, while not introducing relocation overflows in
6055 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6056 generated before or after PLT entries, but not intermingled with
6057 them, such that we can have more lazy PLT entries in range for a
6058 branch to the resolverStub. The resolverStub should be emitted at
6059 the most distant location from the first lazy PLT entry such that
6060 it's still in range for a branch, or closer, if there isn't a need
6061 for so many lazy PLT entries. Additional lazy PLT entries may be
6062 emitted after the resolverStub, as long as branches are still in
6063 range. If the branch goes out of range, longer lazy PLT entries
6066 We could further optimize PLT and lazy PLT entries by giving them
6067 priority in assignment to closer-to-gr17 locations depending on the
6068 number of occurrences of references to them (assuming a function
6069 that's called more often is more important for performance, so its
6070 PLT entry should be faster), or taking hints from the compiler.
