-
-static boolean
+
+ Besides handling virtual table relocs for gc, we have to deal with
+ all sorts of PIC-related relocations. 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. If the branch goes out of range, longer lazy PLT entries
+ are emitted.
+
+ We could further optimize PLT and lazy PLT entries by giving them
+ priority in assignment to closer-to-gr17 locations depending on the
+ number of occurrences of references to them (assuming a function
+ that's called more often is more important for performance, so its
+ PLT entry should be faster), or taking hints from the compiler.
+ Given infinite time and money... :-) */
