Get total number of nodes in graph.

Same as `which` command of bash.

Backwards dataflow analysis that finds arguments to a graph that must be compile-time constants.

Return the deepest context on the stack.

Return whether the param has a zero_point

Check if any nodes with index in `target_idx` can be reached from `src_idx` node. Parameters ---------- src_idx : int

Creates a global const string op named `name` using the value if not exists and returns the Loaded value of this global op.

Removes `value` from the set. Assumes `value` is already present in the set.

Return whether "to" is reachable from "from".
