[PATCH] D79356: [CodeGen][SVE] Add patterns for whole vector predicate select

efriedma added a comment.

It's possible to write a TableGen pattern that explicitly generates an SBFM.  In general that's what we would generate anyway.  But you'd want to do custom lowering to give DAGCombine a chance to combine it away, yes.
