<pre>AFAICT, r279649 introduced a compile-time failure for the following test case:
target datalayout = "e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128"
target triple = "arm64"
define hidden void @foo() local_unnamed_addr {
entry:
br label %for.body.i
for.body.i: ; preds = %for.body.i, %entry
%indvars.iv.i = phi i64 [ 0, %entry ], [ %indvars.iv.next.i, %for.body.i ]
%v_prev.017.i = phi float* [ undef, %entry ], [ %v_curr.020.i, %for.body.i ]
%v_curr.020.i = getelementptr inbounds [3 x float], [3 x float]* undef, i64
0, i64 0
%indvars.iv.next.i = add nuw nsw i64 %indvars.iv.i, 1
%exitcond.i = icmp eq i64 %indvars.iv.next.i, undef
br i1 %exitcond.i, label %for.end.i.loopexit, label %for.body.i
for.end.i.loopexit: ; preds = %for.body.i
ret void
}
Reproduce with: opt test.ll -loop-vectorize</pre>
