4.2. Accessing linker-defined symbols
The linker defines some symbols that contain the character
sequence $$. These symbols, and all other external
names containing the sequence $$, are names reserved
by ARM. The symbols are used to specify region base addresses, output
section base addresses, and input section base addresses and their
limits.
These symbolic addresses can be imported and used as relocatable
addresses by your assembly language programs, or referred to as extern symbols
from your C or C++ source code. See Importing linker-defined symbols for details.
Note
Linker-defined symbols are only generated when your code references
them.
