Chandler Carruth 0fe9a92b33 Switch all of the uses of my InsertDAGNode helper to follow the exact ... same pattern. We already had this pattern is a few places, but others tried to make a rough approximation of an actual DAG structure. As not everywhere went to this trouble, nothing could rely on this being done. In fact, I've checked all references to these node Ids, and the ones that are using the topo-sort properties are actually satisfied with a strict-weak-ordering. The requirement appears to be that Use >= Def. I've added a big blurb of comments to this bit of the transform to clarify why the order is so important for the next reader of the code. I'm starting with this change as it is very small, and trivially reverted if something breaks or the >= above really does need to be >. If that proves the case, we can hide the problem by reverting this patch, but the problem exists elsewhere as well, and so a more comprehensive solution will be needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148001 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-12 01:34:44 +00:00
