	* dse.c (find_shift_sequence): Allow word as well as subword shifts.
	Do the tentative shift expansion with the DF_NO_INSN_RESCAN flag set.
	Fix the call to insn_rtx_cost.  Skip access sizes that require a
	real truncation of the store register.  Use convert_move instead
	of gen_lowpart when narrowing the result.
	(replace_read): Use convert_move instead of gen_lowpart when
	narrowing the store rhs.

	PR fortran/29396
	PR fortran/29606
	PR fortran/30625
	PR fortran/30871
	* trans.h : Add extra argument to gfc_build_array_ref. Rename
	gfc_conv_aliased_arg to gfc_conv_subref_array_arg.  Move
	prototype of is_aliased_array to gfortran.h and rename it
	gfc_is_subref_array.  Add field span to lang_decl, add a new
	decl lang specific flag accessed by GFC_DECL_SUBREF_ARRAY_P
	and a new type flag GFC_DECL_SUBREF_ARRAY_P.
	* trans.c (gfc_build_array_ref): Add the new argument, decl.
	If this is a subreference array pointer, use the lang_decl
	field 'span' to calculate the offset in bytes and use pointer
	arithmetic to address the element.
	* trans-array.c (gfc_conv_scalarized_array_ref,
	gfc_conv_array_ref): Add the backend declaration as the third
	field, if it is likely to be a subreference array pointer.
	(gfc_conv_descriptor_dimension, gfc_trans_array_ctor_element,
	gfc_trans_array_constructor_element, structure_alloc_comps,
	gfc_conv_array_index_offset): For all other references to
	gfc_build_array_ref, set the third argument to NULL.
	(gfc_get_dataptr_offset): New function.
	(gfc_conv_expr_descriptor): If the rhs of a pointer assignment
	is a subreference array, then calculate the offset to the
	subreference of the first element and set the descriptor data
	pointer to this, using gfc_get_dataptr_offset.
	trans-expr.c (gfc_get_expr_charlen): Use the expression for the
	character length for a character subreference.
	(gfc_conv_substring, gfc_conv_subref_array_arg): Add NULL for
	third argument in call to gfc_build_array_ref.
	(gfc_conv_aliased_arg): Rename to gfc_conv_subref_array_arg.
	(is_aliased_array): Remove.
	(gfc_conv_function_call): Change reference to is_aliased_array
	to gfc_is_subref_array and reference to gfc_conv_aliased_arg to
	gfc_conv_subref_array_arg.
	(gfc_trans_pointer_assignment): Add the array element length to
	the lang_decl 'span' field.
	* gfortran.h : Add subref_array_pointer to symbol_attribute and
	add the prototype for gfc_is_subref_array.
	* trans-stmt.c : Add NULL for third argument in all references
	to gfc_build_array_ref.
	* expr.c (gfc_is_subref_array): Renamed is_aliased_array.
	If this is a subreference array pointer, return true.
	(gfc_check_pointer_assign): If the rhs is a subreference array,
	set the lhs subreference_array_pointer attribute.
	* trans-decl.c (gfc_get_symbol_decl): Allocate the lang_decl
	field if the symbol is a subreference array pointer and set an
	initial value of zero for the 'span' field.
	* trans-io.c (set_internal_unit): Refer to is_subref_array and
	gfc_conv_subref_array_arg.
	(nml_get_addr_expr): Add NULL third argument to
	gfc_build_array_ref. 
	(gfc_trans_transfer): Use the scalarizer for a subreference
	array.
