Dan Gohman	500b598c5c	When identifying exit nodes for the reverse-CFG reverse-post-order traversal, consider nodes for which the only successors are backedges which the traversal is ignoring to be exit nodes. This fixes a problem where the bottom-up traversal was failing to visit split blocks along split loop backedges. This fixes rdar://10989035. llvm-svn: 152421	2012-03-09 18:50:52 +00:00

When identifying exit nodes for the reverse-CFG reverse-post-order

traversal, consider nodes for which the only successors are backedges
which the traversal is ignoring to be exit nodes. This fixes a problem
where the bottom-up traversal was failing to visit split blocks along
split loop backedges. This fixes rdar://10989035.

Don't let arbitrary calls disrupt nested retain+release pairs if

the retains and releases all use the same SSA pointer value.

Also, don't let CFG hazards disrupt nested retain+release pair
optimizations.
