/* 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. */
