/* THE RULES for all the stuff the linker creates --
|
43 |
|
|
|
44 |
|
|
GOT Entries created in response to LTOFF or LTOFF_FPTR
|
45 |
|
|
relocations. Dynamic relocs created for dynamic
|
46 |
|
|
symbols in an application; REL relocs for locals
|
47 |
|
|
in a shared library.
|
48 |
|
|
|
49 |
|
|
FPTR The canonical function descriptor. Created for local
|
50 |
|
|
symbols in applications. Descriptors for dynamic symbols
|
51 |
|
|
and local symbols in shared libraries are created by
|
52 |
|
|
ld.so. Thus there are no dynamic relocs against these
|
53 |
|
|
objects. The FPTR relocs for such _are_ passed through
|
54 |
|
|
to the dynamic relocation tables.
|
55 |
|
|
|
56 |
|
|
FULL_PLT Created for a PCREL21B relocation against a dynamic symbol.
|
57 |
|
|
Requires the creation of a PLTOFF entry. This does not
|
58 |
|
|
require any dynamic relocations.
|
59 |
|
|
|
60 |
|
|
PLTOFF Created by PLTOFF relocations. For local symbols, this
|
61 |
|
|
is an alternate function descriptor, and in shared libraries
|
62 |
|
|
requires two REL relocations. Note that this cannot be
|
63 |
|
|
transformed into an FPTR relocation, since it must be in
|
64 |
|
|
range of the GP. For dynamic symbols, this is a function
|
65 |
|
|
descriptor for a MIN_PLT entry, and requires one IPLT reloc.
|
66 |
|
|
|
67 |
|
|
MIN_PLT Created by PLTOFF entries against dynamic symbols. This
|
68 |
|
|
does not require dynamic relocations. */

2248 |
|
|
then use bsearch to do a lookup. This also allows lookups to be
|
2249 |
|
|
fast. So we have fast insertion (O(log N) due to duplicate check),
|
2250 |
|
|
fast lookup (O(log N)) and one sort (O(N log N) expected time).
|
2251 |
|
|
Previously, all lookups were O(N) because of the use of the linked
|
2252 |
|
|
list and also all insertions were O(N) because of the check for
|
2253 |
|
|
duplicates. There are some complications here because the array
|
2254 |
|
|
size grows occasionally, which may add an O(N) factor, but this
|
2255 |
|
|
should be rare. Also, we free the excess array allocation, which
|
2256 |
|
|
requires a copy which is O(N), but this only happens once. */
