Functions
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	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.
bool	is_recursive_artefact (const type_or_decl_base &t)
	Test if an artifact is recursive.
void	is_recursive_artefact (const type_or_decl_base &t, bool f)
	Set the property that flags an artifact as recursive.
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.
