This is the Ada front-end (in fact gigi) part.
ada/
* gcc-interface/gigi.h (set_reverse_storage_order_on_pad_type): Declare
* gcc-interface/decl.c (gnat_to_gnu_entity) <discrete_type>: Set the
storage order on the enclosing record for a packed array type.
<E_Array_Type>: Set the storage order.
<E_Array_Subtype>: Likewise.
<E_Record_Type>: Likewise.
<E_Record_Subtype>: Likewise.
(gnat_to_gnu_component_type): Set the reverse storage order on a padded
type built for a non-bit-packed array.
(gnat_to_gnu_field): Likewise.
(components_to_record): Deal with TYPE_REVERSE_STORAGE_ORDER.
* gcc-interface/utils.c (make_packable_type): Likewise.
(pad_type_hasher::equal): Likewise.
(gnat_types_compatible_p): Likewise.
(unchecked_convert): Likewise.
(set_reverse_storage_order_on_pad_type): New public function.
* gcc-interface/trans.c (Attribute_to_gnu): Adjust call to
get_inner_reference.
* gcc-interface/utils2.c (build_unary_op): Likewise.
(gnat_build_constructor): Deal with TYPE_REVERSE_STORAGE_ORDER.
(gnat_rewrite_reference): Propagate the REF_REVERSE_STORAGE_ORDER flag.

+@itemx scalar_storage_order ("@var{endianness}")
+@cindex @code{scalar_storage_order} type attribute
+When attached to a @code{union} or a @code{struct}, this attribute sets
+the storage order, aka endianness, of the scalar fields of the type, as
+well as the array fields whose component is scalar. The supported
+endianness are @code{big-endian} and @code{little-endian}. The attribute
+has no effects on fields which are themselves a @code{union}, a @code{struct}
+or an array whose component is a @code{union} or a @code{struct}, and it is
+possible to have fields with a different scalar storage order than the
+enclosing type.
+
+This attribute is supported only for targets that use a uniform default
+scalar storage order (fortunately, most of them), i.e. targets that store
+the scalars either all in big-endian or all in little-endian.
+
+Additional restrictions are enforced for types with the reverse scalar
+storage order with regard to the scalar storage order of the target:
+
+@itemize
+@item Taking the address of a scalar field of a @code{union} or a
+@code{struct} with reverse scalar storage order is illegal and will
+yield an error
+@item Taking the address of an array field, whose component is scalar, of
+a @code{union} or a @code{struct} with reverse scalar storage order is
+permitted but will yield a warning, unless @option{-Wno-scalar-storage-order}
+is specified
+@item Taking the address of a @code{union} or a @code{struct} with reverse
+scalar storage order is permitted
+@end itemize
+
+These restrictions exist because the storage order attribute is lost when
+the address of a scalar or the address of an array with scalar component
+is taken, so storing indirectly through this address will generally not work.
+The second case is nevertheless allowed to be able to perform a block copy
+from or to the array.
+
+@item unused
+@cindex @code{unused} type attribute
+When attached to a type (including a @code{union} or a @code{struct}),
+this attribute means that variables of that type are meant to appear
+possibly unused. GCC does not produce a warning for any variables of
+that type, even if the variable appears to do nothing. This is often
+the case with lock or thread classes, which are usually defined and then
+not referenced, but contain constructors and destructors that have
+nontrivial bookkeeping functions.

A very cursory glance at the patch set but should we restrict this
attribute to apply only to scalar types rather than allow them on vector
extensions. I haven't had enough coffee this morning but a first
thought is that if it does apply on vector type extensions, clarifying
the lane ordering up front would be helpful especially as we now allow
indexing into short vectors.

I think it applies to vector types but really it acts the same way as
we apply attributes on arrays, that is on the inner scalar type
instead.

That's reasonable, and the name would sort of imply it, although the current
implementation doesn't do that (but wasn't really tested with vector types).

The ISO standard for Ada contains this (1.1.2 Structure):
Legality Rules
27 Rules that are enforced at compile time. A construct is legal if it obeys
all of the Legality Rules.
and "illegal" is documented in the Index.
But the standard for C doesn't, so I'll change the wording, thanks.

You appear to be duplicating the documentation of an unrelated attribute.

I don't think this type construction is safe when the array type has
qualified element type. The following invariant is meant to hold: for an
array type whose element type (possibly after going down through several
levels of array types) is qualified, the TYPE_MAIN_VARIANT is a
corresponding array type whose element type is unqualified. So in that
case you need to build two sequences of array types, not one: the main
variants with unqualified element type, and the versions with qualified
element type. See c_build_qualified_type.

Merge glitch, now fixed, thanks.

You mean a scalar field contained in an aggregate type with reverse SSO? Then
nothing, nothing is changed for scalars on an individual basis, only their
presence inside an aggregate type with reverse SSO changes something.

It appears that all the C tests check the specific syntactic form
'struct __attr_sso__ foo {...};'
What is the impact of changing the location of __attr_sso__? Eg:
struct foo {...} __attr_sso__;
(Note that alignment attributes can have significant impact depending on
where in the syntax the attribute is placed (I'm expecting this will be
true here as well).
What about with typedefs?
Can I apply the attribute to a previously laid out struct?
Can I apply it to individual fields in the struct, eg:
struct bar
{
int a;
int __attr_sso__ b;
};
Can I modify an existing struct to create an opposite endian variant? Eg.
struct bar
{
int a;
};
struct wibble
{
struct __attr_sso__ bar a;
};
Assuming mixed fields in a struct are possible, can it be applied to
individual bitfields? What is the impact on mixing big and little
endian bitfields in the same structure.
R.

None. What impact could it have?

Ouch. This sounds like a bug to me.
> What about with typedefs?
It's ignored (with a warning) on typedefs.
> Can I apply the attribute to a previously laid out struct?
Example? Is that supported for other type attributes?

No, but you can do this:
struct bar
{
int a;
struct __attr_sso__ foo
{
int b;
} s;
};

The compiler accepts it, but apparently discards the attribute silently, which
looks like a bug to me. Let me investigate.

Mixing bitfields with different endianness is simply not possible, they would
be non-contiguous in one of the orders. The endianness can only be flipped on
storage unit boundaries, which is automatically enforced in the C family of
languages by the aggregate type constraint (but not in Ada, so we have a
specific check to that effect in the Ada compiler).

This looks like an existing hole, the following is also silently accepted:
struct S1 { int i; };
struct S2 { struct __attribute__((unknown_attribute)) S1 s1; };
