9.6.7.2 Addr Built-in Function

The ADDR(section) built-in function returns the absolute address (a VMA) of the named section. Your script must previously have defined the location of that section. In the following example, symbol_1 and symbol_2 are assigned identical values:

SECTIONS { ...
  .output1 :
   {
   start_of_output_1 = ABSOLUTE(.);
   ...
   }   
  .output :
   {
   symbol_1 = ADDR(.output1);
   symbol_2 = start_of_output_1;
   }
...
}
