================
Comment at: llvm/test/Transforms/InstCombine/lifetime-sanitizer.ll:37-50
+define void @msan() sanitize_memory {
+entry:
+  ; CHECK-LABEL: @msan(
+  %text = alloca i8, align 1
+
+  call void @llvm.lifetime.start.p0i8(i64 1, i8* %text)
+  call void @llvm.lifetime.end.p0i8(i64 1, i8* %text)
----------------
Would be good to have end-to-end test (`-O0`/`-O1`/`-O2`/`-O3`) in PhaseOrdering.
