Functions
ir_tarval *	computed_value (const ir_node *n)
	If the expression referenced can be evaluated statically computed_value returns a tarval representing the result.
ir_node *	optimize_in_place (ir_node *n)
	Applies all optimizations to n that are expressible as a pattern in Firm, i.e., they need not a walk of the graph.
int	ir_is_negated_value (const ir_node *a, const ir_node *b)
	checks whether 1 value is the negated other value
ir_relation	ir_get_possible_cmp_relations (const ir_node *left, const ir_node *right)
	(conservatively) approximates all possible relations when comparing the value left and right
