	    Tristan Gingold  <gingold@adacore.com>
	    Olivier Hainque  <hainque@adacore.com>

	* gigi.h, trans.c (Identifier_to_gnu): Change test for deferred
	constant by adding guard that the entity is an E_Constant before
	testing presence of Full_view (and remove now-unnecessary test that
	entity is not a type).
	For a CONST_DECL used by reference, manually retrieve
	the DECL_INITIAL.  Do not invoke fold in the other DECL_P cases either.
	(struct language_function): Move from utils.c to here.
	(struct parm_attr): New structure.
	(parm_attr, parm_attr vector, parm_attr GC vector): New types.
	(f_parm_attr_cache): New macro.
	(Attribute_to_gnu) <Attr_Length>: When not optimizing, cache the
	expressions for the 'First, 'Last and 'Length attributes of the
	unconstrained array IN parameters.
	(Subprogram_Body_to_gnu): Use gnu_subprog_decl throughout.
	Allocate the information structure for the function earlier, as well
	as the language-specific part.
	If the parameter attributes cache has been populated, evaluate the
	cached expressions on entry.

	N_Procedure_Call_Statement and N_Indexed_Component.
	(Pragma_to_gnu): Translate inspection_point to an asm statement
	containaing a comment and a reference to the object (either its address
	for BLKmode or its value).
	(Identifier_to_gnu): Use TREE_CONSTANT instead of CONST_DECL to decide
	to go to DECL_INITIAL. Together with the size constraint relaxation
	in create_var_decl, enlarges the set of situations in which an
	identifier may be used as an initializer without implying elaboration
	code.
	(Subprogram_Body_to_gnu): Do not fiddle with the debug interface but set
	DECL_IGNORED_P on the function if Needs_Debug_Info is not set on the
	node.
	(maybe_stabilize_reference): Remove lvalues_only parameter.
	(gnat_stabilize_reference): Adjust for above change.
	(gnat_to_gnu): Do not set location information on the result
	if it is a reference.

	* utils.c (struct language_function): Move to trans.c from here.
	(unchecked_convert): Do not wrap up integer constants in
	VIEW_CONVERT_EXPRs.
	(create_var_decl_1): Decouple TREE_CONSTANT from CONST_DECL. Prevent
	the latter for aggregate types, unexpected by later passes, and relax an
	arbitrary size constraint on the former.
	(create_field_decl): Use tree_int_cst_equal instead of operand_equal_p
	to compare the sizes.
	(convert_vms_descriptor): When converting to a fat pointer type, be
	prepared for a S descriptor at runtime in spite of a SB specification.
	(shift_unc_components_for_thin_pointers): New function.
	(write_record_type_debug_info): For variable-sized fields, cap the
	alignment of the pointer to the computed alignment.

	(declare_debug_type): New function.

        * misc.c (gnat_expand_expr): Call to gnat_expand_stmt removed because
        no statement is expandable anymore.
        (gnat_init_gcc_eh): Do not initialize the DWARF-2 CFI machinery twice.
        (gnat_handle_option): Only allow flag_eliminate_debug_types to be set
        when the user requested it explicitely.
        (gnat_post_options): By default, set flag_eliminate_unused_debug_types
        to 0 for Ada.
        (get_alias_set): Return alias set 0 for a type if
        TYPE_UNIVERSAL_ALIASING_P is set on its main variant.

        * ada-tree.h: (TYPE_UNIVERSAL_ALIASING_P): New macro.
        (DECL_FUNCTION_STUB): New accessor macro.
