/* A list of declaration specifiers. These are:
|
|
|
|
|
|
2003-07-11 03:40:53 +00:00
|
|
|
|
- Storage class specifiers (scspec), which for GCC currently includes
|
2002-02-01 18:16:02 +00:00
|
|
|
|
function specifiers ("inline").
|
|
|
|
|
|
|
|
|
|
- Type specifiers (typespec_*).
|
|
|
|
|
|
|
|
|
|
- Type qualifiers (TYPE_QUAL).
|
|
|
|
|
|
|
|
|
|
- Attribute specifier lists (attributes).
|
|
|
|
|
|
|
|
|
|
These are stored as a TREE_LIST; the head of the list is the last
|
|
|
|
|
item in the specifier list. Each entry in the list has either a
|
|
|
|
|
TREE_PURPOSE that is an attribute specifier list, or a TREE_VALUE that
|
|
|
|
|
is a single other specifier or qualifier; and a TREE_CHAIN that is the
|
|
|
|
|
rest of the list. TREE_STATIC is set on the list if something other
|
|
|
|
|
than a storage class specifier or attribute has been seen; this is used
|
|
|
|
|
to warn for the obsolescent usage of storage class specifiers other than
|
|
|
|
|
at the start of the list. (Doing this properly would require function
|
|
|
|
|
specifiers to be handled separately from storage class specifiers.)
|
|
|
|
|
|
|
|
|
|
The various cases below are classified according to:
|
|
|
|
|
|
|
|
|
|
(a) Whether a storage class specifier is included or not; some
|
|
|
|
|
places in the grammar disallow storage class specifiers (_sc or _nosc).
|
|
|
|
|
|
|
|
|
|
(b) Whether a type specifier has been seen; after a type specifier,
|
|
|
|
|
a typedef name is an identifier to redeclare (_ts or _nots).
|
|
|
|
|
|
|
|
|
|
(c) Whether the list starts with an attribute; in certain places,
|
|
|
|
|
the grammar requires specifiers that don't start with an attribute
|
|
|
|
|
(_sa or _nosa).
|
|
|
|
|
|
|
|
|
|
(d) Whether the list ends with an attribute (or a specifier such that
|
|
|
|
|
any following attribute would have been parsed as part of that specifier);
|
|
|
|
|
this avoids shift-reduce conflicts in the parsing of attributes
|
|
|
|
|
(_ea or _noea).
|
|
|
|
|
|
|
|
|
|
TODO:
|
|
|
|
|
|
|
|
|
|
(i) Distinguish between function specifiers and storage class specifiers,

Once we have seen one of these in a declaration,
|
2002-02-01 18:16:02 +00:00
|
|
|
|
if a typedef name appears then it is being redeclared.

|
|

2002-02-01 18:16:02 +00:00
|
|
|
|
The _reserved versions start with a reserved word and may appear anywhere
|
|
|
|
|
in the declaration specifiers; the _nonreserved versions may only
|
|
|
|
|
appear before any other type specifiers, and after that are (if names)
|
|
|
|
|
being redeclared.
|
|
|
|
|
|
|
|
|
|
FIXME: should the _nonreserved version be restricted to names being
|
|
|
|
|
redeclared only? The other entries there relate only the GNU extensions
|
|
|
|
|
and Objective C, and are historically parsed thus, and don't make sense
|
|
|
|
|
after other type specifiers, but it might be cleaner to count them as
|
|
|
|
|
_reserved.
|
|
|
|
|
|
|
|
|
|
_attr means: specifiers that either end with attributes,
|
|
|
|
|
or are such that any following attributes would
|
|
|
|
|
be parsed as part of the specifier.
