[Ulrich Weigand via Phabricator via llvm-commits]

uweigand added inline comments.


================
Comment at: llvm/test/CodeGen/SystemZ/prefetch-01.ll:18
 
-; Check that instruction write prefetches are ignored.
-define dso_local void @f2(ptr %ptr) {
-; CHECK-LABEL: f2:
-; CHECK-NOT: %r2
-; CHECK: br %r14
-  call void @llvm.prefetch(ptr %ptr, i32 1, i32 0, i32 0)
-  ret void
-}
+; Instruction write prefetches are invalid.
+; define dso_local void @f2(ptr %ptr) {
----------------
If we decide to declare this invalid, then I'd prefer to remove the test instead of commenting it out.
