/* This testcase caused infinite loop in life info computation

   after if conversion on IA-64.  Conditional register dead for

   pseudo holding sign-extended k was improperly computed,

   resulting in this pseudo being live at start of bb if it was

   dead at the end and vice versa; as it was a bb which had edge

   to itself, this resulted in alternative propagating this basic

   block forever.  */
