/*
 * 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.
