+; CHECK-NEXT:    [[TMP1:%.*]] = call ptr @llvm.ptrmask.p0.i64(ptr @constarray1, i64 [[MASK:%.*]])
+; CHECK-NEXT:    [[TMP2:%.*]] = getelementptr inbounds i16, ptr [[TMP1]], i64 [[IDX:%.*]]
+; CHECK-NEXT:    [[TMP3:%.*]] = load i8, ptr [[TMP2]], align 1
+; CHECK-NEXT:    ret i8 [[TMP3]]
 ;
   %1 = call ptr @llvm.ptrmask.p0.i64(ptr @constarray1, i64 %mask)
+  %2 = getelementptr inbounds i16, ptr %1, i64 %idx
----------------
Tweaked this case not to be folded by alignment.
