Dan Gohman 7ad3cd8c9d 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
