- * THE RULES for all the stuff the linker creates --
- *
- * GOT Entries created in response to LTOFF or LTOFF_FPTR
- * relocations. Dynamic relocs created for dynamic
- * symbols in an application; REL relocs for locals
- * in a shared library.
- *
- * FPTR The canonical function descriptor. Created for local
- * symbols in applications. Descriptors for dynamic symbols
- * and local symbols in shared libraries are created by
- * ld.so. Thus there are no dynamic relocs against these
- * objects. The FPTR relocs for such _are_ passed through
- * to the dynamic relocation tables.
- *
- * FULL_PLT Created for a PCREL21B relocation against a dynamic symbol.
- * Requires the creation of a PLTOFF entry. This does not
- * require any dynamic relocations.
- *
- * PLTOFF Created by PLTOFF relocations. For local symbols, this
- * is an alternate function descriptor, and in shared libraries
- * requires two REL relocations. Note that this cannot be
- * transformed into an FPTR relocation, since it must be in
- * range of the GP. For dynamic symbols, this is a function
- * descriptor for a MIN_PLT entry, and requires one IPLT reloc.
- *
- * MIN_PLT Created by PLTOFF entries against dynamic symbols. This
- * does not reqire dynamic relocations.
