LANCE includes a number of both classical ("Dragon Book") and advanced IR-level code optimization engines. They are implemented as separate tools and can be combined and iterated by a predefined IR optimization script that can be modified or extended to optimize code quality for a specific class of target machines or to plug in new optimization tools. Currently, the following optimization engines are available:

	constant folding
	constant propagation
	copy propagation
	dead code elimination
	common subexpression elimination
	function inlining
	induction variable elimination
	jump optimization
	loop invariant code motion
	SSA conversion
	reassociation
