[Bug fortran/45756] New: Multiple DECL for array valued PARAMETER (-fwhole-file issue)

[burnus at gcc dot gnu dot org]

Currently, gfc_get_symbol_decl only deals with -fwhole-file issues of module
variable (FL_VARIABLE( but not with array-valued (or non-intrinsic-type)
parameters (FL_PARAMETER).

Thus, for the following program, multiple UIDs will be generated for the
program below:

module m
  integer, parameter :: para(3) = [1, 2, 3]
end module m

subroutine one
  use m
  i = para(1)
end subroutine one

subroutine two
  use m
  j = para(1)
end subroutine two


-fdump-tree-original-uid shows:

  extern integer(kind=4)D.8 paraD.1556[3];
  extern integer(kind=4)D.8 paraD.1561[3];

------- Comment #1 from burnus at gcc dot gnu dot org  2010-09-23 09:59 -------
Note: The implementation should honour PR 40571, i.e. array parameters from
intrinsic modules, which do not exist as .o file. My current idea is to
generate them per use association as local static variable - which would break
if uses gsym for them.
