6047 Besides handling virtual table relocs for gc, we have to deal with
6048 all sorts of PIC-related relocations. We describe below the
6049 general plan on how to handle such relocations, even though we only
6050 collect information at this point, storing them in hash tables for
6051 perusal of later passes.
6053 32 relocations are propagated to the linker output when creating
6054 position-independent output. LO16 and HI16 relocations are not
6055 supposed to be encountered in this case.
6057 LABEL16 should always be resolvable by the linker, since it's only
6060 LABEL24, on the other hand, is used by calls. If it turns out that
6061 the target of a call is a dynamic symbol, a PLT entry must be
6062 created for it, which triggers the creation of a private function
6063 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
6065 GPREL relocations require the referenced symbol to be in the same
6066 segment as _gp, but this can only be checked later.
6068 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
6069 exist. LABEL24 might as well, since it may require a PLT entry,
6070 that will require a got.
6072 Non-FUNCDESC GOT relocations require a GOT entry to be created
6073 regardless of whether the symbol is dynamic. However, since a
6074 global symbol that turns out to not be exported may have the same
6075 address of a non-dynamic symbol, we don't assign GOT entries at
6076 this point, such that we can share them in this case. A relocation
6077 for the GOT entry always has to be created, be it to offset a
6078 private symbol by the section load address, be it to get the symbol
6079 resolved dynamically.
6081 FUNCDESC GOT relocations require a GOT entry to be created, and
6082 handled as if a FUNCDESC relocation was applied to the GOT entry in
6085 FUNCDESC relocations referencing a symbol that turns out to NOT be
6086 dynamic cause a private function descriptor to be created. The
6087 FUNCDESC relocation then decays to a 32 relocation that points at
6088 the private descriptor. If the symbol is dynamic, the FUNCDESC
6089 relocation is propagated to the linker output, such that the
6090 dynamic linker creates the canonical descriptor, pointing to the
6091 dynamically-resolved definition of the function.
6093 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
6094 symbols that are assigned to the same segment as the GOT, but we
6095 can only check this later, after we know the complete set of
6096 symbols defined and/or exported.
6098 FUNCDESC GOTOFF relocations require a function descriptor to be
6099 created and, unless lazy binding is disabled or the symbol is not
6100 dynamic, a lazy PLT entry. Since we can't tell at this point
6101 whether a symbol is going to be dynamic, we have to decide later
6102 whether to create a lazy PLT entry or bind the descriptor directly
6103 to the private function.
6105 FUNCDESC_VALUE relocations are not supposed to be present in object
6106 files, but they may very well be simply propagated to the linker
6107 output, since they have no side effect.
6110 A function descriptor always requires a FUNCDESC_VALUE relocation.
6111 Whether it's in .plt.rel or not depends on whether lazy binding is
6112 enabled and on whether the referenced symbol is dynamic.
6114 The existence of a lazy PLT requires the resolverStub lazy PLT
6115 entry to be present.
6118 As for assignment of GOT, PLT and lazy PLT entries, and private
6119 descriptors, we might do them all sequentially, but we can do
6120 better than that. For example, we can place GOT entries and
6121 private function descriptors referenced using 12-bit operands
6122 closer to the PIC register value, such that these relocations don't
6123 overflow. Those that are only referenced with LO16 relocations
6124 could come next, but we may as well place PLT-required function
6125 descriptors in the 12-bit range to make them shorter. Symbols
6126 referenced with LO16/HI16 may come next, but we may place
6127 additional function descriptors in the 16-bit range if we can
6128 reliably tell that we've already placed entries that are ever
6129 referenced with only LO16. PLT entries are therefore generated as
6130 small as possible, while not introducing relocation overflows in
6131 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6132 generated before or after PLT entries, but not intermingled with
6133 them, such that we can have more lazy PLT entries in range for a
6134 branch to the resolverStub. The resolverStub should be emitted at
6135 the most distant location from the first lazy PLT entry such that
6136 it's still in range for a branch, or closer, if there isn't a need
6137 for so many lazy PLT entries. Additional lazy PLT entries may be
6138 emitted after the resolverStub, as long as branches are still in
6139 range. If the branch goes out of range, longer lazy PLT entries
6142 We could further optimize PLT and lazy PLT entries by giving them
6143 priority in assignment to closer-to-gr17 locations depending on the
6144 number of occurrences of references to them (assuming a function
6145 that's called more often is more important for performance, so its
6146 PLT entry should be faster), or taking hints from the compiler.
