Hi Igor,

I can hazard a guess, but I cannot give you a definitive answer:
The reason I suspect is so that these sections contain function pointers
and so they should be considered to be part of the executable region of
the program. This might be important on architectures which make a
distinction between data and code fetches.
Cheers
