bool canonicalize_attr_name	(	const char *&	s,

Return TRUE iff ATTR has been parsed by the front-end as a C++-11
attribute.

When G++ parses a C++11 attribute, it is represented as
a TREE_LIST which TREE_PURPOSE is itself a TREE_LIST.  TREE_PURPOSE
(TREE_PURPOSE (ATTR)) is the namespace of the attribute, and the
TREE_VALUE (TREE_PURPOSE (ATTR)) is its non-qualified name.  Please
use get_attribute_namespace and get_attribute_name to retrieve the
namespace and name of the attribute, as these accessors work with
GNU attributes as well.

extern

Process the attributes listed in ATTRIBUTES and install them in *NODE,
which is either a DECL (including a TYPE_DECL) or a TYPE.  If a DECL,
it should be modified in place; if a TYPE, a copy should be created
unless ATTR_FLAG_TYPE_IN_PLACE is set in FLAGS.  FLAGS gives further
information, in the form of a bitwise OR of flags in enum attribute_flags
from tree.h.  Depending on these flags, some attributes may be
returned to be applied at a later stage (for example, to apply
a decl attribute to the declaration rather than to its type).

extern

Return the number of mismatched function or type attributes between
the "template" function declaration TMPL and DECL.  The word "template"
doesn't necessarily refer to a C++ template but rather a declaration
whose attributes should be matched by those on DECL.  For a non-zero
return value set *ATTRSTR to a string representation of the list of
mismatched attributes with quoted names.
ATTRLIST is a list of additional attributes that SPEC should be
taken to ultimately be declared with.

Make a dispatcher declaration for the multi-versioned function DECL.
Calls to DECL function will be replaced with calls to the dispatcher
by the front-end.  Return the decl created.

◆ maybe_diag_alias_attributes()

void maybe_diag_alias_attributes	(	tree	alias,
		tree	target )

extern

Issue a warning for the declaration ALIAS for TARGET where ALIAS
specifies either attributes that are incompatible with those of
TARGET, or attributes that are missing and that declaring ALIAS
with would benefit.

extern

Given two attributes lists, return a list of their union.

Return an attribute list that is the union of a1 and a2.

Given decls OLDDECL and NEWDECL, merge their attributes and return
the result.

◆ merge_dllimport_decl_attributes()

dllimport, return a list of their union .

◆ private_lookup_attribute() [1/2]

tree private_lookup_attribute	(	const char *	attr_name,
		size_t	attr_len,
		tree	list )

extern

The backbone of lookup_attribute().  ATTR_LEN is the string length
of ATTR_NAME, and LIST is not NULL_TREE.

The function is called from lookup_attribute in order to optimize
for size.

		size_t	attr_len,
		tree	list )

extern

Similarly but with also attribute namespace.

◆ register_scoped_attributes()

struct scoped_attributes * register_scoped_attributes	(	const scoped_attribute_specs &	specs,
		bool	ignored_p )

extern

Insert SPECS into its namespace.  IGNORED_P is true iff all unknown
attributes in this namespace should be ignored for the purposes of
-Wattributes.  The function returns the namespace into which the
attributes have been registered.

◆ remove_attribute() [1/2]

tree remove_attribute	(	const char *	attr_ns,
		const char *	attr_name,
		tree	list )

extern

Similarly but also with specific attribute namespace.

Similarly but also match namespace on the removed attributes.
ATTR_NS "" stands for NULL or "gnu" namespace.

◆ remove_attribute() [2/2]

tree remove_attribute	(	const char *	attr_name,
		tree	list )

extern

Remove any instances of attribute ATTR_NAME in LIST and return the
modified list.

◆ restrict_type_identity_attributes_to()

tree restrict_type_identity_attributes_to	(	tree	attrs,
		tree	ok_attrs )

extern

Remove attributes that affect type identity from ATTRS unless the
same attributes occur in OK_ATTRS.

◆ simple_cst_list_equal()

bool simple_cst_list_equal	(	const_tree	l1,
		const_tree	l2 )

extern

Compare two constructor-element-type constants.  Return 1 if the lists
are known to be equal; otherwise return 0.

◆ sorted_attr_string()

char * sorted_attr_string ( tree arglist )

extern

ARGLIST is the argument to target attribute.  This function tokenizes
the comma separated arguments, sorts them and returns a string which
is a unique identifier for the comma separated arguments.   It also
replaces non-identifier characters "=,-" with "_".
