Andreas Molzer	af72a70ee2	Move post order walk to iterative approach ... The previous recursive approach might overflow the stack when walking a particularly deep, list-like, graph. In particular, dominator calculation for borrow checking does such a traversal and very long functions might lead to a region dependency graph with in this problematic structure.	2020-10-31 18:52:00 +01:00

Leonora Tindall	84daccc559	change the order of type arguments on ControlFlow ... This allows ControlFlow<BreakType> which is much more ergonomic for common iterator combinator use cases.	2020-10-22 17:26:48 -07:00
