librustc_mir: Fix ICE with slice patterns If a match arm does not include all fields in a structure and a later pattern includes a field that is an array, we will attempt to use the array type from the prior arm. When calculating the field type, treat a array of an unknown size as a TyErr. 2019-01-13 08:23:32 -06:00			`error: unreachable pattern`
