+ * 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.
