* Re-sort #include lines for unittests. This uses a slightly modifiedChandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | clang-format (https://reviews.llvm.org/D33932) to keep primary headers at the top and handle new utility headers like 'gmock' consistently with other utility headers. No other change was made. I did no manual edits, all of this is clang-format. This should allow other changes to have more clear and focused diffs, and is especially motivated by moving some headers into more focused libraries. llvm-svn: 304786
* Modify df_iterator to support post-order actionsDavid Callahan2016-10-051-0/+2
| | | | | | | | | | | | Summary: This makes a change to the state used to maintain visited information for depth first iterator. We know assume a method "completed(...)" which is called after all children of a node have been visited. In all existing cases, this method does nothing so this patch has no functional changes. It will however allow a client to distinguish back from cross edges in a DFS tree.

* [ADT] Actually mutate the iterator VisitStack.back().second, not its copy.Tim Shen2016-08-221-0/+52
Summary: Before the change, *Opt never actually gets updated by the end of toNext(), so for every next time the loop has to start over from child_begin(). This bug doesn't affect the correctness, since Visited prevents it from re-entering the same node again; but it's slow.
