These are described using the following target hooks; they also need to

-@deftypevr {Target Hook} {const struct attribute_spec *} TARGET_ATTRIBUTE_TABLE
-If defined, this target hook points to an array of @samp{struct
-attribute_spec} (defined in @file{tree-core.h}) specifying the machine
-specific attributes for this target and some of the restrictions on the
-entities to which these attributes are applied and the arguments they
-take.
+@deftypevr {Target Hook} {array_slice<const struct scoped_attribute_specs *const>} TARGET_ATTRIBUTE_TABLE
+If defined, this target hook provides an array of
+@samp{scoped_attribute_spec}s (defined in @file{attribs.h}) that specify the
+machine-specific attributes for this target. The information includes some
+of the restrictions on the entities to which these attributes are applied
+and the arguments that the attributes take.
+
+In C and C++, these attributes are associated with two syntaxes:
+the traditional GNU @code{__attribute__} syntax and the standard
+@samp{[[]]} syntax. Attributes that support the GNU syntax must be
+placed in the @code{gnu} namespace. Such attributes can then also be
+written @samp{[[gnu::@dots{}]]}. Attributes that use only the standard
+syntax should be placed in whichever namespace the attribute specification
+requires. For example, a target might choose to support vendor-specific
+@samp{[[]]} attributes that the vendor places in their own namespace.
+
+Targets that only define attributes in the @code{gnu} namespace
+can uase the following shorthand to define the table:
+
+@smallexample

+ @{ "@var{attribute1}", @dots{} @},
