+@item 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 not permitted 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
