	PR fortran/97694
	PR fortran/97723
	* check.c (allocatable_check): Select rank temporaries are
	permitted even though they are treated as associate variables.
	* resolve.c (gfc_resolve_code): Break on select rank as well as
	select type so that the block os resolved.
	* trans-stmt.c (trans_associate_var): Class associate variables

	PR fortran/98022
	* data.c (gfc_assign_data_value): Throw an error for inquiry
	references. Follow with corrected code that would provide the
	expected result and provides clean error recovery.

2020-12-26  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/83118
	* trans-array.c (gfc_alloc_allocatable_for_assignment): Make
	sure that class expressions are captured for dummy arguments by
	use of gfc_get_class_from_gfc_expr otherwise the wrong vptr is
	used.
	* trans-expr.c (gfc_get_class_from_gfc_expr): New function.
	(gfc_get_class_from_expr): If a constant expression is
	encountered, return NULL_TREE;
	(gfc_trans_assignment_1): Deallocate rhs allocatable components
	after passing derived type function results to class lhs.
	* trans.h : Add prototype for gfc_get_class_from_gfc_expr.

	(gfc_trans_allocate_array_storage): Defer obtaining class
	element type until all sources of class exprs are tried. Use
	class API rather than TREE_OPERAND. Look for class expressions
	in ss->info by calling get_class_info_from_ss. After, obtain
	the element size for class descriptors. Where the element type
	is unknown, cast the data as character(len=size) to overcome
	unlimited polymorphic problems.

	replicating the new function gfc_resize_class_size_with_len.

	element sizes are the same. Use earlier evaluation of
	'cond_null'. Reallocation of lhs only to happen if size changes
	or element size changes.
	* trans-expr.c (gfc_resize_class_size_with_len): New function.
	(gfc_get_class_from_expr): If a constant expression is
	encountered, return NULL_TREE;

	(gfc_conv_procedure_call): Ensure the vtable is present for
	passing a non-class actual to an unlimited formal.
	(trans_class_vptr_len_assignment): For expressions of type
	BT_CLASS, extract the class expression if necessary. Use a
	statement block outside the loop body. Ensure that 'rhs' is
	of the correct type. Obtain rhs vptr in all circumstances.
	(gfc_trans_scalar_assign): Call trans_scalar_class_assign to
	make maximum use of the vptr copy in place of assignment.
	(trans_class_assignment): Actually do reallocation if needed.
	(gfc_trans_assignment_1): Simplify some of the logic with
	'realloc_flag'. Set 'vptr_copy' for all array assignments to
	unlimited polymorphic lhs.
	* trans.c (gfc_build_array_ref): Call gfc_resize_class_size_
	with_len to correct span for unlimited polymorphic decls.
