29 * THE RULES for all the stuff the linker creates --
30 *
31 * GOT Entries created in response to LTOFF or LTOFF_FPTR
32 * relocations. Dynamic relocs created for dynamic
33 * symbols in an application; REL relocs for locals
34 * in a shared library.
35 *
36 * FPTR The canonical function descriptor. Created for local
37 * symbols in applications. Descriptors for dynamic symbols
38 * and local symbols in shared libraries are created by
39 * ld.so. Thus there are no dynamic relocs against these
40 * objects. The FPTR relocs for such _are_ passed through
41 * to the dynamic relocation tables.
42 *
43 * FULL_PLT Created for a PCREL21B relocation against a dynamic symbol.
44 * Requires the creation of a PLTOFF entry. This does not
45 * require any dynamic relocations.
46 *
47 * PLTOFF Created by PLTOFF relocations. For local symbols, this
48 * is an alternate function descriptor, and in shared libraries
49 * requires two REL relocations. Note that this cannot be
50 * transformed into an FPTR relocation, since it must be in
51 * range of the GP. For dynamic symbols, this is a function
52 * descriptor for a MIN_PLT entry, and requires one IPLT reloc.
53 *
54 * MIN_PLT Created by PLTOFF entries against dynamic symbols. This
55 * does not reqire dynamic relocations.
