860 function specifiers ("inline").
862 - Type specifiers (typespec_*).
864 - Type qualifiers (TYPE_QUAL).
866 - Attribute specifier lists (attributes).
868 These are stored as a TREE_LIST; the head of the list is the last
869 item in the specifier list. Each entry in the list has either a
870 TREE_PURPOSE that is an attribute specifier list, or a TREE_VALUE that
871 is a single other specifier or qualifier; and a TREE_CHAIN that is the
872 rest of the list. TREE_STATIC is set on the list if something other
873 than a storage class specifier or attribute has been seen; this is used
874 to warn for the obsolescent usage of storage class specifiers other than
875 at the start of the list. (Doing this properly would require function
876 specifiers to be handled separately from storage class specifiers.)
878 The various cases below are classified according to:
880 (a) Whether a storage class specifier is included or not; some
881 places in the grammar disallow storage class specifiers (_sc or _nosc).
883 (b) Whether a type specifier has been seen; after a type specifier,
884 a typedef name is an identifier to redeclare (_ts or _nots).
886 (c) Whether the list starts with an attribute; in certain places,
887 the grammar requires specifiers that don't start with an attribute
890 (d) Whether the list ends with an attribute (or a specifier such that
891 any following attribute would have been parsed as part of that specifier);
892 this avoids shift-reduce conflicts in the parsing of attributes
897 (i) Distinguish between function specifiers and storage class specifiers,
898 at least for the purpose of warnings about obsolescent usage.
900 (ii) Halve the number of productions here by eliminating the _sc/_nosc
901 distinction and instead checking where required that storage class
902 specifiers aren't present. */
