Dan Gohman 8f7b6c8113 Fix a bug in LSR's dead-PHI cleanup. If a PHI has a def-use chain that ... leads into a cycle involving a different PHI, LSR got stuck running around that cycle looking for the original PHI. To avoid this, keep track of visited PHIs and stop searching if we see one more than once. This fixes PR2570. llvm-svn: 53879		2008-07-21 21:45:02 +00:00
