L251 linker-defined symbols

Hi All, 

In the ARM toolchain, there is such a thing as linker-defined symbols and could be identify with the delimiter $$

  "The linker defines some symbols that contain the character sequence $$. T
  hese symbols, and all other external names containing the sequence $$, are names reserved by ARM."


   So when checking the ARM generated map file.. i could just look for $$ . 


Question :

How about when using L251? for this toolchain do we have such thing as linker defined symbols? and if yes, how could i identify them in the mapfile?
