[Bug fortran/31218] ICE on valid code with gfortran

[fxcoudert at gcc dot gnu dot org]

------- Comment #5 from fxcoudert at gcc dot gnu dot org  2007-05-04 12:31 -------
RESHAPE is not simplified, because "x" has type EXPR_CONSTANT (scalar constant)
which is not accepted by the simplification routine gfc_simplify_reshape,
because it wants arguments to be EXPR_ARRAY (ie array constructor). Thus, the
following code fails to compile:
  integer, parameter :: x(1) = 1, y(1) = reshape(x,(/1/))
  print *, y
  end
while that other one works fine:
  integer, parameter :: x(1) = (/1/), y(1) = reshape(x,(/1/))
  print *, y
  end

I don't know if it's OK for x to have type EXPR_CONSTANT, but I think it is. In
that case, gfc_simplify_reshape should be modified to account for this
possibility.
