Michael Kuperstein 7f9bd29a16 [DAGCombine] Don't fold a trunc if it feeds an anyext ... Legalization tends to create anyext(trunc) patterns. This should always be combined - into either a single trunc, a single ext, or nothing if the types match exactly. But if we happen to combine the trunc first, we may pull the trunc away from the anyext or make it implicit (e.g. the truncate(extract) -> extract(bitcast) fold). To prevent this, we can avoid doing the fold, similarly to how we already handle fpround(fpextend). Differential Revision: https://reviews.llvm.org/D23893 llvm-svn: 280386		2016-09-01 17:59:24 +00:00
