Chris Lattner 98df4f9cf2 Make DSE only scan blocks that are reachable from the entry ... block. Other blocks may have pointer cycles that will crash basicaa and other alias analyses. In any case, there is no point wasting cycles optimizing dead blocks. This fixes rdar://7635088 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95852 91177308-0d34-0410-b5e6-96231b3b80d8		2010-02-11 05:11:54 +00:00
