+// This pass is an extremely simple version of the SimplifyCFG pass. Its sole
+// job is to delete LLVM basic blocks that are not reachable from the entry
+// node. To do this, it performs a simple depth first traversal of the CFG,
+// then deletes any unvisited nodes.
+//
+// Note that this pass is really a hack. In particular, the instruction
+// selectors for various targets should just not generate code for unreachable
+// blocks. Until LLVM has a more systematic way of defining instruction
+// selectors, however, we cannot really expect them to handle additional
+// complexity.
