We describe below the + general plan on how to handle such relocations, even though we only + collect information at this point, storing them in hash tables for + perusal of later passes. + + 32 relocations are propagated to the linker output when creating + position-independent output. LO16 and HI16 relocations are not + supposed to be encountered in this case. + + LABEL16 should always be resolvable by the linker, since it's only + used by branches. + + LABEL24, on the other hand, is used by calls. If it turns out that + the target of a call is a dynamic symbol, a PLT entry must be + created for it, which triggers the creation of a private function + descriptor and, unless lazy binding is disabled, a lazy PLT entry. + + GPREL relocations require the referenced symbol to be in the same + segment as _gp, but this can only be checked later. + + All GOT, GOTOFF and FUNCDESC relocations require a .got section to + exist. LABEL24 might as well, since it may require a PLT entry, + that will require a got. + + Non-FUNCDESC GOT relocations require a GOT entry to be created + regardless of whether the symbol is dynamic. However, since a + global symbol that turns out to not be exported may have the same + address of a non-dynamic symbol, we don't assign GOT entries at + this point, such that we can share them in this case. A relocation + for the GOT entry always has to be created, be it to offset a + private symbol by the section load address, be it to get the symbol + resolved dynamically. + + FUNCDESC GOT relocations require a GOT entry to be created, and + handled as if a FUNCDESC relocation was applied to the GOT entry in + an object file. + + FUNCDESC relocations referencing a symbol that turns out to NOT be + dynamic cause a private function descriptor to be created. The + FUNCDESC relocation then decays to a 32 relocation that points at + the private descriptor. If the symbol is dynamic, the FUNCDESC + relocation is propagated to the linker output, such that the + dynamic linker creates the canonical descriptor, pointing to the + dynamically-resolved definition of the function. + + Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic + symbols that are assigned to the same segment as the GOT, but we + can only check this later, after we know the complete set of + symbols defined and/or exported. + + FUNCDESC GOTOFF relocations require a function descriptor to be + created and, unless lazy binding is disabled or the symbol is not + dynamic, a lazy PLT entry. Since we can't tell at this point + whether a symbol is going to be dynamic, we have to decide later + whether to create a lazy PLT entry or bind the descriptor directly + to the private function. + + FUNCDESC_VALUE relocations are not supposed to be present in object + files, but they may very well be simply propagated to the linker + output, since they have no side effect. + + + A function descriptor always requires a FUNCDESC_VALUE relocation. + Whether it's in .plt.rel or not depends on whether lazy binding is + enabled and on whether the referenced symbol is dynamic. + + The existence of a lazy PLT requires the resolverStub lazy PLT + entry to be present. + + + As for assignment of GOT, PLT and lazy PLT entries, and private + descriptors, we might do them all sequentially, but we can do + better than that. For example, we can place GOT entries and + private function descriptors referenced using 12-bit operands + closer to the PIC register value, such that these relocations don't + overflow. Those that are only referenced with LO16 relocations + could come next, but we may as well place PLT-required function + descriptors in the 12-bit range to make them shorter. Symbols + referenced with LO16/HI16 may come next, but we may place + additional function descriptors in the 16-bit range if we can + reliably tell that we've already placed entries that are ever + referenced with only LO16. PLT entries are therefore generated as + small as possible, while not introducing relocation overflows in + GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be + generated before or after PLT entries, but not intermingled with + them, such that we can have more lazy PLT entries in range for a + branch to the resolverStub. The resolverStub should be emitted at + the most distant location from the first lazy PLT entry such that + it's still in range for a branch, or closer, if there isn't a need + for so many lazy PLT entries. Additional lazy PLT entries may be + emitted after the resolverStub, as long as branches are still in + range.
