Bob Wilson c52edc7d30 Fix handling of unreachable blocks in the SSAUpdater. The previous code only ... handled cases where a block had zero predecessors, but failed to detect other cases like loops with no entries. The SSAUpdater is already doing a forward traversal through the blocks, so it is not hard to identify the blocks that were never reached on that traversal. This fixes the crash for ppc on the stepanov_vector test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103184 91177308-0d34-0410-b5e6-96231b3b80d8		2010-05-06 16:24:11 +00:00
