b34976b6 | 44 | |
5e8d7549 NC |
45 | GOT Entries created in response to LTOFF or LTOFF_FPTR |
46 | relocations. Dynamic relocs created for dynamic | |
47 | symbols in an application; REL relocs for locals | |
48 | in a shared library. | |
b34976b6 | 49 | |
5e8d7549 NC |
50 | FPTR The canonical function descriptor. Created for local |
51 | symbols in applications. Descriptors for dynamic symbols | |
52 | and local symbols in shared libraries are created by | |
53 | ld.so. Thus there are no dynamic relocs against these | |
54 | objects. The FPTR relocs for such _are_ passed through | |
55 | to the dynamic relocation tables. | |
b34976b6 | 56 | |
5e8d7549 NC |
57 | FULL_PLT Created for a PCREL21B relocation against a dynamic symbol. |
58 | Requires the creation of a PLTOFF entry. This does not | |
59 | require any dynamic relocations. | |
b34976b6 | 60 | |
5e8d7549 NC |
61 | PLTOFF Created by PLTOFF relocations. For local symbols, this |
62 | is an alternate function descriptor, and in shared libraries | |
63 | requires two REL relocations. Note that this cannot be | |
64 | transformed into an FPTR relocation, since it must be in | |
65 | range of the GP. For dynamic symbols, this is a function | |
66 | descriptor for a MIN_PLT entry, and requires one IPLT reloc. | |
b34976b6 | 67 | |
5e8d7549 | 68 | MIN_PLT Created by PLTOFF entries against dynamic symbols. This |
4cc11e76 | 69 | does not require dynamic relocations. */ |

2319 | fast lookup (O(log N)) and one sort (O(N log N) expected time). | |
2320 | Previously, all lookups were O(N) because of the use of the linked | |

2322 | duplicates. There are some complications here because the array | |
2323 | size grows occasionally, which may add an O(N) factor, but this | |
2324 | should be rare. Also, we free the excess array allocation, which | |
