5e8d7549 | 28 | /* THE RULES for all the stuff the linker creates -- |
b34976b6 | 29 | |
5e8d7549 NC |
30 | GOT Entries created in response to LTOFF or LTOFF_FPTR |
31 | relocations. Dynamic relocs created for dynamic | |
32 | symbols in an application; REL relocs for locals | |
33 | in a shared library. | |
b34976b6 | 34 | |
5e8d7549 NC |
35 | FPTR The canonical function descriptor. Created for local |
36 | symbols in applications. Descriptors for dynamic symbols | |
37 | and local symbols in shared libraries are created by | |
38 | ld.so. Thus there are no dynamic relocs against these | |
39 | objects. The FPTR relocs for such _are_ passed through | |
40 | to the dynamic relocation tables. | |
b34976b6 | 41 | |
5e8d7549 NC |
42 | FULL_PLT Created for a PCREL21B relocation against a dynamic symbol. |
43 | Requires the creation of a PLTOFF entry. This does not | |
44 | require any dynamic relocations. | |
b34976b6 | 45 | |
5e8d7549 NC |
46 | PLTOFF Created by PLTOFF relocations. For local symbols, this |
47 | is an alternate function descriptor, and in shared libraries | |
48 | requires two REL relocations. Note that this cannot be | |
49 | transformed into an FPTR relocation, since it must be in | |
50 | range of the GP. For dynamic symbols, this is a function | |
51 | descriptor for a MIN_PLT entry, and requires one IPLT reloc. | |
b34976b6 | 52 | |
5e8d7549 NC |
53 | MIN_PLT Created by PLTOFF entries against dynamic symbols. This |
54 | does not reqire dynamic relocations. */ | |
