2006-12-09 Paul Thomas <pault@gcc.gnu.org> PR fortran/29975 PR fortran/30068 PR fortran/30096 * interface.c (compare_type_rank_if): Reject invalid generic interfaces. (check_interface1): Give a warning for nonreferred to ambiguous interfaces. (check_sym_interfaces): Check whether an ambiguous interface is referred to. Do not check host associated interfaces since these cannot be ambiguous with the local versions. (check_uop_interface, gfc_check_interfaces): Update call to check_interface1. * symbol.c (gfc_get_sym_tree, gfc_get_sym_tree): Allow adding unambiguous procedures to generic interfaces. * gfortran.h (symbol_attribute): Added use_only and ambiguous_interfaces. * module.c (load_need): Set the use_only flag, if needed. * resolve.c (resolve_fl_procedure): Warn for nonreferred interfaces. * expr.c (find_array_section): Fix initializer array contructor. 2006-12-09 Paul Thomas <pault@gcc.gnu.org> Tobias Burnus <burnus@gcc.gnu.org> PR fortran/29975 PR fortran/30068 * gfortran.dg/interface_4.f90: Test adding procedure to generic interface. * gfortran.dg/interface_5.f90: Test warning for not-referenced-to ambiguous interfaces. * gfortran.dg/interface_6.f90: Test invalid, ambiguous interface. * gfortran.dg/interface_7.f90: Test invalid, ambiguous interface. * gfortran.dg/interface_8.f90: Test warning for not-referenced-to ambiguous interfaces. * gfortran.dg/interface_1.f90: Change dg-error into a dg-warning. * gfortran.dg/array_initializer_2.f90: Add initializer array constructor test.
