 ; Do a bunch of analysis and prove that the loops can use an i32 trip
 ; count without casting.
+;
+; Note that all four functions should actually be converted to
+; memset. However, this test case validates indvars behavior.  We
+; don't check that phis are "folded together" because that is a job
+; for loop strength reduction. But indvars must remove sext, zext, and add i8.
+;
+; CHECK-NOT: {{sext|zext|add i8}}
