================
Comment at: llvm/test/Transforms/DeadArgElim/multdeadretval.ll:12
+; DEBUG: %oldret = extractvalue { i16, i32 } %B, 1, !dbg
+; DEBUG: %oldret = extractvalue { i32, i16 } %B, 0, !dbg
+; DEBUG: %oldret = insertvalue { i16, i32 } undef, i32 %ret, 1, !dbg
----------------
Thanks!

Should we also check that the !dbg attachment is the same as some other instruction? Or are we really fine with just *any* !dbg location?
