Namespaces
namespace	abigail
	Toplevel namespace for libabigail.

	The namespace of the internal representation of ABI artifacts like types and decls.

Macros

Functions
void	add_to_hashing_state (const ir::type_or_decl_base &tod, hashing::hashing_state s)
	Add a state to the hashing state of a given IR node.
hash_t	combine_hashes (hash_t val1, hash_t val2)
	Combine two hash values to produce a third hash value.
bool	deserialize_hash (const string &input, uint64_t &hash)
	Read a string of characters representing a string of hexadecimal digits which itself represents a hash value that was computed using the XH64 algorithm from the xxhash project.
uint32_t	fnv_hash (const std::string &str)
	Compute a stable string hash.
hashing::hashing_state	get_hashing_state (const type_or_decl_base &tod)
	Get the hashing state of an IR node.
hash_t	get_subtype_hash (const type_or_decl_base *t)
	Compute (or get) the hash of a sub-type of the type for which we are currently computing the hash. It does so by preventing infinite loops.
hash_t	get_subtype_hash (type_or_decl_base_sptr t)
	Compute (or get) the hash of a sub-type of the type for which we are currently computing the hash. It does so by preventing infinite loops.
hash_t	hash (const std::string &str)
	Hash a string.
hash_t	hash (uint64_t v, uint64_t seed)
	Hash an integer value and combine it with a hash previously computed.
void	remove_from_hashing_state (const ir::type_or_decl_base &tod, hashing::hashing_state s)
	Remove a state to the hashing state of a given IR node.
bool	serialize_hash (uint64_t hash, string &output)
	Serialiaze a hash value computed using the XH64 algorithm (from the xxhash project) into a string of characters representing the digits of the hash in the canonical form requested by the xxhash project. That canonical form is basically a big endian representation of the hexadecimal hash number.
void	set_hashing_state (const type_or_decl_base &tod, hashing::hashing_state s)
	Set the hashing state of an IR node.
