From fd23cc08b8e00c13605b9c13b35b07c8b89c7f6b Mon Sep 17 00:00:00 2001 From: pault Date: Sun, 11 Dec 2011 20:42:23 +0000 Subject: 2011-12-11 Paul Thomas Tobias Burnus PR fortran/41539 PR fortran/43214 PR fortran/43969 PR fortran/44568 PR fortran/46356 PR fortran/46990 PR fortran/49074 * interface.c(symbol_rank): Return the rank of the _data component of class objects. (compare_parameter): Also compare the derived type of the class _data component for type mismatch. Similarly, return 1 if the formal and _data ranks match. (compare_actual_formal): Do not compare storage sizes for class expressions. It is an error if an actual class array, passed to a formal class array is not full. * trans-expr.c (gfc_class_data_get, gfc_class_vptr_get, gfc_vtable_field_get, gfc_vtable_hash_get, gfc_vtable_size_get, gfc_vtable_extends_get, gfc_vtable_def_init_get, gfc_vtable_copy_get): New functions for class API. (gfc_conv_derived_to_class): For an array reference in an elemental procedure call retain the ss to provide the scalarized array reference. Moved in file. (gfc_conv_class_to_class): New function. (gfc_conv_subref_array_arg): Use the type of the class _data component as a basetype. (gfc_conv_procedure_call): Ensure that class array expressions have both the _data reference and an array reference. Use gfc_conv_class_to_class to handle class arrays for elemental functions in scalarized loops, class array elements and full class arrays. Use a call to gfc_conv_subref_array_arg in order that the copy-in/copy-out for passing class arrays to derived type arrays occurs correctly. (gfc_conv_expr): If it is missing, add the _data component between a class object or component and an array reference. (gfc_trans_class_array_init_assign): New function. (gfc_trans_class_init_assign): Call it for array expressions. * trans-array.c (gfc_add_loop_ss_code): Do not use a temp for class scalars since their size will depend on the dynamic type. (build_class_array_ref): New function. (gfc_conv_scalarized_array_ref): Call build_class_array_ref. (gfc_array_init_size): Add extra argument, expr3, that represents the SOURCE argument. If present,use this for the element size. (gfc_array_allocate): Also add argument expr3 and use it when calling gfc_array_init_size. (structure_alloc_comps): Enable class arrays. * class.c (gfc_add_component_ref): Carry over the derived type of the _data component. (gfc_add_class_array_ref): New function. (class_array_ref_detected): New static function. (gfc_is_class_array_ref): New function that calls previous. (gfc_is_class_scalar_expr): New function. (gfc_build_class_symbol): Throw not implemented error for assumed size class arrays. Remove error that prevents CLASS arrays. (gfc_build_class_symbol): Prevent pointer/allocatable conflict. Also unset codimension. (gfc_find_derived_vtab): Make 'copy' elemental and set the intent of the arguments accordingly.: * trans-array.h : Update prototype for gfc_array_allocate. * array.c (gfc_array_dimen_size): Return failure if class expr. (gfc_array_size): Likewise. * gfortran.h : New prototypes for gfc_add_class_array_ref, gfc_is_class_array_ref and gfc_is_class_scalar_expr. * trans-stmt.c (trans_associate_var): Exclude class targets from test. Move the allocation of the _vptr to an earlier time for class objects. (trans_associate_var): Assign the descriptor directly for class arrays. (gfc_trans_allocate): Add expr3 to gfc_array_allocate arguments. Convert array element references into sections. Do not invoke gfc_conv_procedure_call, use gfc_trans_call instead. * expr.c (gfc_get_corank): Fix for BT_CLASS. (gfc_is_simply_contiguous): Exclude class from test. * trans.c (gfc_build_array_ref): Include class array refs. * trans.h : Include prototypes for class API functions that are new in trans-expr. Define GFC_DECL_CLASS(node). * resolve.c (check_typebound_baseobject ): Remove error for non-scalar base object. (resolve_allocate_expr): Ensure that class _data component is present. If array, call gfc_expr_to_intialize. (resolve_select): Remove scalar error for SELECT statement as a temporary measure. (resolve_assoc_var): Update 'target' (aka 'selector') as needed. Ensure that the target expression has the right rank. (resolve_select_type): Ensure that target expressions have a valid locus. (resolve_allocate_expr, resolve_fl_derived0): Fix for BT_CLASS. * trans-decl.c (gfc_get_symbol_decl): Set GFC_DECL_CLASS, where appropriate. (gfc_trans_deferred_vars): Get class arrays right. * match.c(select_type_set_tmp): Add array spec to temporary. (gfc_match_select_type): Allow class arrays. * check.c (array_check): Ensure that class arrays have refs. (dim_corank_check, dim_rank_check): Retrun success if class. * primary.c (gfc_match_varspec): Fix for class arrays and co-arrays. Make sure that class _data is present. (gfc_match_rvalue): Handle class arrays. *trans-intrinsic.c (gfc_conv_intrinsic_size): Add class array reference. (gfc_conv_allocated): Add _data component to class expressions. (gfc_add_intrinsic_ss_code): ditto. * simplify.c (simplify_cobound): Fix for BT_CLASS. (simplify_bound): Return NULL for class arrays. (simplify_cobound): Obtain correct array_spec. Use cotype as appropriate. Use arrayspec for bounds. 2011-12-11 Paul Thomas Tobias Burnus PR fortran/41539 PR fortran/43214 PR fortran/43969 PR fortran/44568 PR fortran/46356 PR fortran/46990 PR fortran/49074 * gfortran.dg/class_array_1.f03: New. * gfortran.dg/class_array_2.f03: New. * gfortran.dg/class_array_3.f03: New. * gfortran.dg/class_array_4.f03: New. * gfortran.dg/class_array_5.f03: New. * gfortran.dg/class_array_6.f03: New. * gfortran.dg/class_array_7.f03: New. * gfortran.dg/class_array_8.f03: New. * gfortran.dg/coarray_poly_1.f90: New. * gfortran.dg/coarray_poly_2.f90: New. * gfortran.dg/coarray/poly_run_1.f90: New. * gfortran.dg/coarray/poly_run_2.f90: New. * gfortran.dg/class_to_type_1.f03: New. * gfortran.dg/type_to_class_1.f03: New. * gfortran.dg/typebound_assignment_3.f03: Remove the error. * gfortran.dg/auto_dealloc_2.f90: Occurences of __builtin_free now 2. * gfortran.dg/class_19.f03: Occurences of __builtin_free now 8. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@182210 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/fortran/trans.c | 28 +++++++++++++++++++++++++--- 1 file changed, 25 insertions(+), 3 deletions(-) (limited to 'gcc/fortran/trans.c') diff --git a/gcc/fortran/trans.c b/gcc/fortran/trans.c index 88bd389c545..085f58f608a 100644 --- a/gcc/fortran/trans.c +++ b/gcc/fortran/trans.c @@ -315,6 +315,7 @@ gfc_build_array_ref (tree base, tree offset, tree decl) { tree type = TREE_TYPE (base); tree tmp; + tree span; if (GFC_ARRAY_TYPE_P (type) && GFC_TYPE_ARRAY_RANK (type) == 0) { @@ -345,12 +346,33 @@ gfc_build_array_ref (tree base, tree offset, tree decl) if (decl && (TREE_CODE (decl) == FIELD_DECL || TREE_CODE (decl) == VAR_DECL || TREE_CODE (decl) == PARM_DECL) - && GFC_DECL_SUBREF_ARRAY_P (decl) - && !integer_zerop (GFC_DECL_SPAN(decl))) + && ((GFC_DECL_SUBREF_ARRAY_P (decl) + && !integer_zerop (GFC_DECL_SPAN(decl))) + || GFC_DECL_CLASS (decl))) { + if (GFC_DECL_CLASS (decl)) + { + /* Allow for dummy arguments and other good things. */ + if (POINTER_TYPE_P (TREE_TYPE (decl))) + decl = build_fold_indirect_ref_loc (input_location, decl); + + /* Check if '_data' is an array descriptor.
