re PR fortran/26393 (ICE with function returning variable lenght array)
2006-03-01 Paul Thomas <pault@gcc.gnu.org> * iresolve.c (gfc_resolve_dot_product): Remove any difference in treatment of logical types. * trans-intrinsic.c (gfc_conv_intrinsic_dot_product): New function. PR fortran/26393 * trans-decl.c (gfc_get_symbol_decl): Extend condition that symbols must be referenced to include unreferenced symbols in an interface body. PR fortran/20938 * trans-array.c (gfc_conv_resolve_dependencies): Add call to gfc_are_equivalenced_arrays. * symbol.c (gfc_free_equiv_infos, gfc_free_equiv_lists): New functions. (gfc_free_namespace): Call them. * trans-common.c (copy_equiv_list_to_ns): New function. (add_equivalences): Call it. * gfortran.h: Add equiv_lists to gfc_namespace and define gfc_equiv_list and gfc_equiv_info. * dependency.c (gfc_are_equivalenced_arrays): New function. (gfc_check_dependency): Call it. * dependency.h: Prototype for gfc_are_equivalenced_arrays. 2006-03-01 Paul Thomas <pault@gcc.gnu.org> * gfortran.dg/logical_dot_product.f90: New test. PR fortran/26393 * gfortran.dg/used_interface_ref.f90: New test. PR fortran/20938 * gfortran.dg/dependency_2.f90: New test. * gfortran.fortran-torture/execute/where17.f90: New test. * gfortran.fortran-torture/execute/where18.f90: New test. * gfortran.fortran-torture/execute/where19.f90: New test. * gfortran.fortran-torture/execute/where20.f90: New test.
