bool isArtificialDep() const
bool isCtrlDep() const
Tests if this is not an SDep::Data dependence.
Scheduling unit. This is a node in the scheduling DAG.
virtual std::string getDAGName() const =0
Returns a label for the region of code covered by the DAG.
virtual void viewGraph()
Out-of-line implementation with no arguments is handy for gdb.

A raw_ostream that writes to an std::string.
This is an optimization pass for GlobalISel generic memory operations.
LLVM_ABI raw_fd_ostream & errs()
This returns a reference to a raw_ostream for standard error.
void ViewGraph(const GraphType &G, const Twine &Name, bool ShortNames=false, const Twine &Title="", GraphProgram::Name Program=GraphProgram::DOT)
ViewGraph - Emit a dot graph, run 'dot', run gv on the postscript file, then cleanup.

static std::string getEdgeAttributes(const SUnit *Node, SUnitIterator EI, const ScheduleDAG *Graph)
If you want to override the dot attributes printed for a particular edge, override this method.
