brief special transfer function for top of expression subtrees. -- Special transfer function: this one is called at the top of every expression subtree. These are not necessarily basic blocks because they may contain operators like "?:" and "&&" which have control-flow semantics. However, we can easily preprocess the tree to remove these. NOTE: This isn't for "real" basicblockNodes; this is for expressions which sort of act like basic blocks Definition at line 139 of file dataflow.h. References flow_node(). |
