Jakob Stoklund Olesen	dd5bbc298e	Allow for multiple legalization patterns for the same opcode. ... Each input pattern can have a predicate in addition to an opcode being matched. When an opcode has multiple patterns, execute the first pattern with a true predicate. The predicates can be type checks or instruction predicates checking immediate fields.	2017-07-28 13:54:25 -07:00
