I wonder whether there is a general missed-optimization issue for FL_PARAMETER
(for the case they are stored as actual data and not just as drop-in number).
One might need some special handling, but I also do not see "para"
("__m_MOD_para:") marked as .rodata for

module m
  integer, parameter :: PARA(*) = [1,2,3,4,5,6,7,8,9,10]
end module m

use m
print *, para
end
