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