Chris Lattner 97b07c2096 Extricate the "reverse" support from the depth-first iterator. This is really ... a crappy form of post-order traversal which really does not belong here. While we are at it, improve documentation and use a vector instead of a stack. This improves the post dominator analysis pass by ~5%, and probably also helps other passes as well. llvm-svn: 9084		2003-10-13 15:45:33 +00:00
