[PATCH] D28190: [LVI] Switch from BFS to DFS exploration strategy

joerg added a comment.

I have one case in pkgsrc (gmic) which currently hits the 2GB VA limit for build processes. Taking the problematic example and comparing before/after on Linux I get:
before: 1.9GB max RSS
after: 0.9GB max RSS

E.g. in this case, it effectively cuts memory use in half. That's quite significant and something I would like to see in 4.0.
