--- Comment #18 from vehre at gcc dot gnu.org --- Author: vehre Date: Sat Oct 22 12:33:38 2016 New Revision: 241439 URL: https://gcc.gnu.org/viewcvs?rev=241439&root=gcc&view=rev Log: gcc/fortran/ChangeLog: 2016-10-22 Andre Vehreschild <ve...@gcc.gnu.org> PR fortran/43366 PR fortran/51864 PR fortran/57117 PR fortran/61337 PR fortran/61376 * primary.c (gfc_expr_attr): For transformational functions on classes get the attrs from the class argument. * resolve.c (resolve_ordinary_assign): Remove error message due to feature implementation. Rewrite POINTER_ASSIGNS to ordinary ones when the right-hand side is scalar class object (with some restrictions). * trans-array.c (trans_array_constructor): Create the temporary from class' inner type, i.e., the derived type. (build_class_array_ref): Add support for class array's storage of the class object or the array descriptor in the decl saved descriptor. (gfc_conv_expr_descriptor): When creating temporaries for class objects add the class object's handle into the decl saved descriptor. (structure_alloc_comps): Use the common way to get the _data component. (gfc_is_reallocatable_lhs): Add notion of allocatable class objects. * trans-expr.c (gfc_find_and_cut_at_last_class_ref): Remove the only ref only when the expression's type is BT_CLASS. (gfc_trans_class_init_assign): Correctly handle class arrays. (gfc_trans_class_assign): Joined into gfc_trans_assignment_1. (gfc_conv_procedure_call): Support for class types as arguments. (trans_get_upoly_len): For unlimited polymorphics retrieve the _len component's tree. (trans_class_vptr_len_assignment): Catch all ways to assign the _vptr and _len components of a class object correctly. (pointer_assignment_is_proc_pointer): Identify assignments of procedure pointers. (gfc_trans_pointer_assignment): Enhance support for class object pointer assignments. (gfc_trans_scalar_assign): Removed assert. (trans_class_assignment): Assign to a class object. (gfc_trans_assignment_1): Treat class objects correctly. (gfc_trans_assignment): Propagate flags to trans_assignment_1. * trans-stmt.c (gfc_trans_allocate): Use gfc_trans_assignment now instead of copy_class_to_class. * trans-stmt.h: Function prototype removed. * trans.c (trans_code): Less special casing for class objects. * trans.h: Added flags to gfc_trans_assignment () prototype. gcc/testsuite/ChangeLog: 2016-10-22 Andre Vehreschild <ve...@gcc.gnu.org> Forgot to add on original commit. * gfortran.dg/coarray_alloc_comp_2.f08: New test. 2016-10-22 Andre Vehreschild <ve...@gcc.gnu.org> PR fortran/43366 PR fortran/57117 PR fortran/61337 * gfortran.dg/alloc_comp_class_5.f03: New test. * gfortran.dg/class_allocate_21.f90: New test. * gfortran.dg/class_allocate_22.f90: New test. * gfortran.dg/realloc_on_assign_27.f08: New test.
