Fix PR6047 Nodes that had children outside of the post dominator tree (infinite loops) where removed from the post dominator tree. This seems to be wrong. Leave them in the tree. llvm-svn: 93633 2010-01-16 21:38:07 +08:00			`; RUN: opt < %s -postdomtree -analyze \| FileCheck %s`

Revert "Fix PR 24415 (at least), by making our post-dominator tree behavior sane." and also "clang-format GenericDomTreeConstruction.h, since the current formatting makes it look like their is a bug in the loop indentation, and there is not" This reverts commit r296535. There are still some open design questions which I would like to discuss. I revert this for Daniel (who gave the OK), as he is on vacation. llvm-svn: 296812 2017-03-03 05:08:37 +08:00			`; CHECK: [4] %entry`
