5e8d7549 | 41 | /* THE RULES for all the stuff the linker creates -- |
b34976b6 | 42 | |
5e8d7549 NC |
43 | GOT Entries created in response to LTOFF or LTOFF_FPTR |
44 | relocations. Dynamic relocs created for dynamic | |
45 | symbols in an application; REL relocs for locals | |
46 | in a shared library. | |
b34976b6 | 47 | |
5e8d7549 NC |
48 | FPTR The canonical function descriptor. Created for local |
49 | symbols in applications. Descriptors for dynamic symbols | |
50 | and local symbols in shared libraries are created by | |
51 | ld.so. Thus there are no dynamic relocs against these | |
52 | objects. The FPTR relocs for such _are_ passed through | |
53 | to the dynamic relocation tables. | |
b34976b6 | 54 | |
5e8d7549 NC |
55 | FULL_PLT Created for a PCREL21B relocation against a dynamic symbol. |
56 | Requires the creation of a PLTOFF entry. This does not | |
57 | require any dynamic relocations. | |
b34976b6 | 58 | |
5e8d7549 NC |
59 | PLTOFF Created by PLTOFF relocations. For local symbols, this |
60 | is an alternate function descriptor, and in shared libraries | |
61 | requires two REL relocations. Note that this cannot be | |
62 | transformed into an FPTR relocation, since it must be in | |
63 | range of the GP. For dynamic symbols, this is a function | |
64 | descriptor for a MIN_PLT entry, and requires one IPLT reloc. | |
b34976b6 | 65 | |
5e8d7549 | 66 | MIN_PLT Created by PLTOFF entries against dynamic symbols. This |
4cc11e76 | 67 | does not require dynamic relocations. */ |
