It would be very good if gcc could provide some options to move all
counter in a given separate section and another for all coverage data
(structures and strings). Actually there are no such options. I tried to
change generated .s file but with no success (I don't know how to
generate a common section in a new section, .comm/.lcomm generate always
in .bss section).

I'll write to gcc ML.
