Jakob Stoklund Olesen	58dedb673a	Add an AllocatableSet for registers. ... This set of available register units also manages register aliasing in an efficient way. Detect if the units in a register straddles mask words. The algorithm for allocating multi-unit registers expect the whole register to be inside a single mask word. We could handle this if necessary, but so far no ISAs need it.	2017-01-23 12:43:32 -08:00
