51532845
AO		 5997
5998 Besides handling virtual table relocs for gc, we have to deal with
5999 all sorts of PIC-related relocations. We describe below the
6000 general plan on how to handle such relocations, even though we only
6001 collect information at this point, storing them in hash tables for
6002 perusal of later passes.
6003
6004 32 relocations are propagated to the linker output when creating
6005 position-independent output. LO16 and HI16 relocations are not
6006 supposed to be encountered in this case.
6007
6008 LABEL16 should always be resolvable by the linker, since it's only
6009 used by branches.
6010
6011 LABEL24, on the other hand, is used by calls. If it turns out that
6012 the target of a call is a dynamic symbol, a PLT entry must be
6013 created for it, which triggers the creation of a private function
6014 descriptor and, unless lazy binding is disabled, a lazy PLT entry.
6015
6016 GPREL relocations require the referenced symbol to be in the same
6017 segment as _gp, but this can only be checked later.
6018
6019 All GOT, GOTOFF and FUNCDESC relocations require a .got section to
6020 exist. LABEL24 might as well, since it may require a PLT entry,
6021 that will require a got.
6022
6023 Non-FUNCDESC GOT relocations require a GOT entry to be created
6024 regardless of whether the symbol is dynamic. However, since a
6025 global symbol that turns out to not be exported may have the same
6026 address of a non-dynamic symbol, we don't assign GOT entries at
6027 this point, such that we can share them in this case. A relocation
6028 for the GOT entry always has to be created, be it to offset a
6029 private symbol by the section load address, be it to get the symbol
6030 resolved dynamically.
6031
6032 FUNCDESC GOT relocations require a GOT entry to be created, and
6033 handled as if a FUNCDESC relocation was applied to the GOT entry in
6034 an object file.
6035
6036 FUNCDESC relocations referencing a symbol that turns out to NOT be
6037 dynamic cause a private function descriptor to be created. The
6038 FUNCDESC relocation then decays to a 32 relocation that points at
6039 the private descriptor. If the symbol is dynamic, the FUNCDESC
6040 relocation is propagated to the linker output, such that the
6041 dynamic linker creates the canonical descriptor, pointing to the
6042 dynamically-resolved definition of the function.
6043
6044 Non-FUNCDESC GOTOFF relocations must always refer to non-dynamic
6045 symbols that are assigned to the same segment as the GOT, but we
6046 can only check this later, after we know the complete set of
6047 symbols defined and/or exported.
6048
6049 FUNCDESC GOTOFF relocations require a function descriptor to be
6050 created and, unless lazy binding is disabled or the symbol is not
6051 dynamic, a lazy PLT entry. Since we can't tell at this point
6052 whether a symbol is going to be dynamic, we have to decide later
6053 whether to create a lazy PLT entry or bind the descriptor directly
6054 to the private function.
6055
6056 FUNCDESC_VALUE relocations are not supposed to be present in object
6057 files, but they may very well be simply propagated to the linker
6058 output, since they have no side effect.
6059
6060
6061 A function descriptor always requires a FUNCDESC_VALUE relocation.
6062 Whether it's in .plt.rel or not depends on whether lazy binding is
6063 enabled and on whether the referenced symbol is dynamic.
6064
6065 The existence of a lazy PLT requires the resolverStub lazy PLT
6066 entry to be present.
6067
6068
6069 As for assignment of GOT, PLT and lazy PLT entries, and private
6070 descriptors, we might do them all sequentially, but we can do
6071 better than that. For example, we can place GOT entries and
6072 private function descriptors referenced using 12-bit operands
6073 closer to the PIC register value, such that these relocations don't
6074 overflow. Those that are only referenced with LO16 relocations
6075 could come next, but we may as well place PLT-required function
6076 descriptors in the 12-bit range to make them shorter. Symbols
6077 referenced with LO16/HI16 may come next, but we may place
6078 additional function descriptors in the 16-bit range if we can
6079 reliably tell that we've already placed entries that are ever
6080 referenced with only LO16. PLT entries are therefore generated as
6081 small as possible, while not introducing relocation overflows in
6082 GOT or FUNCDESC_GOTOFF relocations. Lazy PLT entries could be
6083 generated before or after PLT entries, but not intermingled with
6084 them, such that we can have more lazy PLT entries in range for a
6085 branch to the resolverStub. The resolverStub should be emitted at
6086 the most distant location from the first lazy PLT entry such that
6087 it's still in range for a branch, or closer, if there isn't a need
6088 for so many lazy PLT entries. Additional lazy PLT entries may be
6089 emitted after the resolverStub, as long as branches are still in
6090 range. If the branch goes out of range, longer lazy PLT entries
6091 are emitted.
6092
6093 We could further optimize PLT and lazy PLT entries by giving them
6094 priority in assignment to closer-to-gr17 locations depending on the
6095 number of occurrences of references to them (assuming a function
6096 that's called more often is more important for performance, so its
6097 PLT entry should be faster), or taking hints from the compiler.
6098 Given infinite time and money... :-) */
