6058 Besides handling virtual table relocs for gc, we have to deal with
6059 all sorts of PIC-related relocations. We describe below the
6060 general plan on how to handle such relocations, even though we only
6061 collect information at this point, storing them in hash tables for
6062 perusal of later passes.
6064 32 relocations are propagated to the linker output when creating
6065 position-independent output. LO16 and HI16 relocations are not
6066 supposed to be encountered in this case.
6068 LABEL16 should always be resolvable by the linker, since it's only
6071 LABEL24, on the other hand, is used by calls. If it turns out that
6072 the target of a call is a dynamic symbol, a PLT entry must be
6073 created for it, which triggers the creation of a private function
6074 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
6076 GPREL relocations require the referenced symbol to be in the same
6077 segment as _gp, but this can only be checked later.
6079 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
6080 exist. LABEL24 might as well, since it may require a PLT entry,
6081 that will require a got.
6083 Non-FUNCDESC GOT relocations require a GOT entry to be created
6084 regardless of whether the symbol is dynamic. However, since a
6085 global symbol that turns out to not be exported may have the same
6086 address of a non-dynamic symbol, we don't assign GOT entries at
6087 this point, such that we can share them in this case. A relocation
6088 for the GOT entry always has to be created, be it to offset a
6089 private symbol by the section load address, be it to get the symbol
6090 resolved dynamically.
6092 FUNCDESC GOT relocations require a GOT entry to be created, and
6093 handled as if a FUNCDESC relocation was applied to the GOT entry in
6096 FUNCDESC relocations referencing a symbol that turns out to NOT be
6097 dynamic cause a private function descriptor to be created. The
6098 FUNCDESC relocation then decays to a 32 relocation that points at
6099 the private descriptor. If the symbol is dynamic, the FUNCDESC
6100 relocation is propagated to the linker output, such that the
6101 dynamic linker creates the canonical descriptor, pointing to the
6102 dynamically-resolved definition of the function.
6104 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
6105 symbols that are assigned to the same segment as the GOT, but we
6106 can only check this later, after we know the complete set of
6107 symbols defined and/or exported.
6109 FUNCDESC GOTOFF relocations require a function descriptor to be
6110 created and, unless lazy binding is disabled or the symbol is not
6111 dynamic, a lazy PLT entry. Since we can't tell at this point
6112 whether a symbol is going to be dynamic, we have to decide later
6113 whether to create a lazy PLT entry or bind the descriptor directly
6114 to the private function.
6116 FUNCDESC_VALUE relocations are not supposed to be present in object
6117 files, but they may very well be simply propagated to the linker
6118 output, since they have no side effect.
6121 A function descriptor always requires a FUNCDESC_VALUE relocation.
6122 Whether it's in .plt.rel or not depends on whether lazy binding is
6123 enabled and on whether the referenced symbol is dynamic.
6125 The existence of a lazy PLT requires the resolverStub lazy PLT
6126 entry to be present.
6129 As for assignment of GOT, PLT and lazy PLT entries, and private
6130 descriptors, we might do them all sequentially, but we can do
6131 better than that. For example, we can place GOT entries and
6132 private function descriptors referenced using 12-bit operands
6133 closer to the PIC register value, such that these relocations don't
6134 overflow. Those that are only referenced with LO16 relocations
6135 could come next, but we may as well place PLT-required function
6136 descriptors in the 12-bit range to make them shorter. Symbols
6137 referenced with LO16/HI16 may come next, but we may place
6138 additional function descriptors in the 16-bit range if we can
6139 reliably tell that we've already placed entries that are ever
6140 referenced with only LO16. PLT entries are therefore generated as
6141 small as possible, while not introducing relocation overflows in
6142 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6143 generated before or after PLT entries, but not intermingled with
6144 them, such that we can have more lazy PLT entries in range for a
6145 branch to the resolverStub. The resolverStub should be emitted at
6146 the most distant location from the first lazy PLT entry such that
6147 it's still in range for a branch, or closer, if there isn't a need
6148 for so many lazy PLT entries. Additional lazy PLT entries may be
6149 emitted after the resolverStub, as long as branches are still in
6150 range. If the branch goes out of range, longer lazy PLT entries
6153 We could further optimize PLT and lazy PLT entries by giving them
6154 priority in assignment to closer-to-gr17 locations depending on the
6155 number of occurrences of references to them (assuming a function
6156 that's called more often is more important for performance, so its
6157 PLT entry should be faster), or taking hints from the compiler.
