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