Diego Novillo 97add46aee Fix dominator descendants for unreachable blocks. ... When a block is unreachable, asking its dom tree descendants should return the empty set. However, the computation of the descendants was causing a segmentation fault because the dom tree node we get from the basic block is initially NULL. Fixed by adding a test for a valid dom tree node before we iterate. The patch also adds some unit tests to the existing dom tree tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196099 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-02 14:08:27 +00:00
