Bob Wilson 8d0b53dc62 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. llvm-svn: 103184		2010-05-06 16:24:11 +00:00
