Jonas Paulsson 18a7c886c0 New method SDep::isNormalMemoryOrBarrier() in ScheduleDAGInstrs.cpp. ... Used to iterate over previously added memory dependencies in adjustChainDeps() and iterateChainSucc(). SDep::isCtrl() was previously used in these places, that also gave anti and output edges. The code may be worse if these are followed, because MisNeedChainEdge() will conservatively return true since a non-memory instruction has no memory operands, and a false chain dep will be added. It is also unnecessary since all memory accesses of interest will be reached by memory dependencies, and there is a budget limit for the number of edges traversed. This problem was found on an out-of-tree target with enabled alias analysis. No test case for an in-tree target has been found.
