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