This would be most naturally expressed as a coroutine with pseudocode that looks like this:

Die cur_die = concrete;

set

<Die

> seen_origin_dies;

while (cur_die) {

// Go through the children at this level

for (Die child : cur_die.children()) {

if (!seen_origin_dies_.contains(child))

YIELD child;

seen_origin_dies.insert(child.abstract_origin());

}

// Move up one level in the abstract origin hierarchy.

cur_die = cur_die.abstract_origin();

}

The logic here represents this loop in "unrolled" for as a single C++ iterator.

Public Methods

void Iter ()

Default-constructed one indicates the end. Computing the true end for this iterator requires

going through all of the abstract origins is slow, expecially since this is only used to

compute the loop termination. By ensuring that "everything clear" indicates end(), we can

save this work.
