2024-05-15  Jakub Jelinek  <jakub@redhat.com>

	PR c/115103
	* openmp.cc (resolve_omp_clauses): Diagnose grainsize
	used together with num_tasks or nogroup used together with
	reduction.

2024-05-13  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/113363
	* trans-array.cc (gfc_array_init_size): Use the expr3 dtype so
	that the correct element size is used.
	* trans-expr.cc (gfc_conv_procedure_call): Remove restriction
	that ss and ss->loop be present for the finalization of class
	array function results.
	(trans_class_assignment): Use free and malloc, rather than
	realloc, for character expressions assigned to unlimited poly
	entities.
	* trans-stmt.cc (gfc_trans_allocate): Build a correct rhs for
	the assignment of an unlimited polymorphic 'source'.

2024-05-12  Harald Anlauf  <anlauf@gmx.de>

	* primary.cc (gfc_match_varspec): Replace 'ref' argument to
	is_inquiry_ref() by NULL when the result is not needed to avoid
	a memleak.

2024-05-12  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/84006
	PR fortran/100027
	PR fortran/98534
	* iresolve.cc (gfc_resolve_transfer): Emit a TODO error for
	unlimited polymorphic mold.
	* trans-expr.cc (gfc_resize_class_size_with_len): Use the fold
	even if a block is not available in which to fix the result.
	(trans_class_assignment): Enable correct assignment of
	character expressions to unlimited polymorphic variables using
	lhs _len field and rse string_length.
	* trans-intrinsic.cc (gfc_conv_intrinsic_storage_size): Extract
	the class expression so that the unlimited polymorphic class
	expression can be used in gfc_resize_class_size_with_len to
	obtain the storage size for character payloads. Guard the use
	of GFC_DECL_SAVED_DESCRIPTOR by testing for DECL_LANG_SPECIFIC
	to prevent the ICE. Also, invert the order to use the class
	expression extracted from the argument.
	(gfc_conv_intrinsic_transfer): In same way as 'storage_size',
	use the _len field to obtaining the correct length for arg 1.
	Add a branch for the element size in bytes of class expressions
	with provision to make use of the unlimited polymorphic _len
	field. Again, the class references are explicitly identified.
	'mold_expr' was already declared. Use it instead of 'arg'. Do
	not fix 'dest_word_len' for deferred character sources because
	reallocation on assign makes use of it before it is assigned.

2024-05-11  Harald Anlauf  <anlauf@gmx.de>

	PR fortran/115039

	Set _len of lhs to _len of rhs.
	* trans-expr.cc (trans_class_assignment): Take into account _len
	of unlimited polymorphic entities for allocation size.

	* trans-stmt.cc (gfc_trans_allocate): Change the initializer
	code for allocate with mold to EXEC_ALLOCATE to allow an
	initializer with all NULL fields.

	PR fortran/89462

	calls to build_sym.

2024-04-21  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/103471
	* resolve.cc (resolve_actual_arglist): Catch variables silently
	set as untyped, resetting the flag so that gfc_resolve_expr can
	generate the no implicit type error.
	(gfc_resolve_index_1): Block index expressions of unknown type
	from being converted to default integer, avoiding the fatal
	error in trans-decl.cc.
	* symbol.cc (gfc_set_default_type): Remove '(symbol)' from the
	'no IMPLICIT type' error message.
	* trans-decl.cc (gfc_get_symbol_decl): Change fatal error locus

	checking for derived types with the right component name.

2024-04-16  Harald Anlauf  <anlauf@gmx.de>

	PR fortran/113793
	* resolve.cc (resolve_allocate_expr): Reject ALLOCATE with SOURCE=
	or MOLD= specifier for unequal length.
	* trans-stmt.cc (gfc_trans_allocate): If an allocatable character
	variable has fixed length, use it and do not use the source length.

	PR fortran/89645
	PR fortran/99065
	PR fortran/114141
	PR fortran/114280
	* class.cc (gfc_change_class): New function needed for
	associate names, when rank changes or a derived type is
	produced by resolution
	* dump-parse-tree.cc (show_code_node): Make output for SELECT
	TYPE more comprehensible.
	* expr.cc (find_inquiry_ref): Do not simplify expressions of
	an inferred type.
	* gfortran.h : Add 'gfc_association_list' to structure
	'gfc_association_list'. Add prototypes for
	'gfc_find_derived_types', 'gfc_fixup_inferred_type_refs' and
	'gfc_change_class'. Add macro IS_INFERRED_TYPE.
	* match.cc (copy_ts_from_selector_to_associate): Add bolean arg
	'select_type' with default false. If this is a select type name
	and the selector is a inferred type, build the class type and
	apply it to the associate name.
	(build_associate_name): Pass true to 'select_type' in call to
	previous.
	* parse.cc (parse_associate): If the selector is inferred type
	the associate name is too. Make sure that function selector
	class and rank, if known, are passed to the associate name. If
	a function result exists, pass its typespec to the associate
	name.
	* primary.cc (resolvable_fcns): New function to check that all
	the function references are resolvable.
	(gfc_match_varspec): If a scalar derived type select type
	temporary has an array reference, match the array reference,
	treating this in the same way as an equivalence member. Do not
	set 'inquiry' if applied to an unknown type the inquiry name
	is ambiguous with the component of an accessible derived type.
	Check that resolution of the target expression is OK by testing
	if the symbol is declared or is an operator expression, then
	using 'resolvable_fcns' recursively. If all is well, resolve
	the expression. If this is an inferred type with a component
	reference, call 'gfc_find_derived_types' to find a suitable
	derived type. If there is an inquiry ref and the symbol either
	is of unknown type or is inferred to be a derived type, set the
	primary and symbol TKR appropriately.
	* resolve.cc (resolve_variable): Call new function below.
	(gfc_fixup_inferred_type_refs): New function to ensure that the
	expression references for a inferred type are consistent with
	the now fixed up selector.
	(resolve_assoc_var): Ensure that derived type or class function
	selectors transmit the correct arrayspec to the associate name.
	(resolve_select_type): If the selector is an associate name of
	inferred type and has no component references, the associate
	name should have its typespec. Simplify the conversion of a
	class array to class scalar by calling 'gfc_change_class'.
	Make sure that a class, inferred type selector with an array
	ref transfers the typespec from the symbol to the expression.
	* symbol.cc (gfc_set_default_type): If an associate name with
	unknown type has a selector expression, try resolving the expr.
	(find_derived_types, gfc_find_derived_types): New functions
	that search for a derived type with a given name.
	* trans-expr.cc (gfc_conv_variable): Some inferred type exprs
	escape resolution so call 'gfc_fixup_inferred_type_refs'.
	* trans-stmt.cc (trans_associate_var): Tidy up expression for
	'class_target'. Finalize and free class function results.
	Correctly handle selectors that are class functions and class
	array references, passed as derived types.

	clause. Adjust 'n->u.map_op' to 'n->u.map.op'.
	(gfc_match_oacc_declare): Adjust 'n->u.map_op' to 'n->u.map.op'.
	(gfc_match_oacc_cache): Add readonly modifier parsing for OpenACC
	cache directive.

	(gfc_arith_divide): Set "Division by zero" only for regular
	numerators of real and complex divisions.
	(reduce_unary): Use is_hard_arith_error to determine whether a hard

	PR fortran/82943
	PR fortran/86148
	PR fortran/86268
	* decl.cc (gfc_get_pdt_instance): Set the PDT instance field
	'f2k_derived', if not set already, to point to the given
	PDT template 'f2k_derived' namespace in order to give the
	PDT instance referential access to the typebound procedures
	of the template.
	* gfortran.h (gfc_pdt_is_instance_of): Add prototype.
	* resolve.cc (resolve_typebound_procedure): If the derived type
	does not have the attribute 'pdt_template' set, compare the
	dummy argument to the 'resolve_bindings_derived' type like usual.
	If the derived type is a 'pdt_template', then check if the
	dummy argument is an instance of the PDT template. If the derived
	type is a PDT template, and the dummy argument is an instance of
	that template, but the dummy argument 'param_list' is not
	SPEC_ASSUMED, check if there are any LEN parameters in the
	dummy argument. If there are no LEN parameters, then this implies
	that there are only KIND parameters in the dummy argument.
	If there are LEN parameters, this would be an error, for all
	LEN parameters for the dummy argument MUST be assumed for
	typebound procedures of PDTs.
	(resolve_pdt): Add a check for ALLOCATABLE and POINTER attributes for
	SPEC_DEFERRED parameters of PDT class symbols.  ALLOCATABLE and
	POINTER attributes for a PDT class symbol are stored in the
	'class_pointer' and 'allocatable' attributes of the '_data'
	component respectively.
	* symbol.cc (gfc_pdt_is_instance_of): New function.
