kadircet planned changes to this revision. kadircet added a comment. this requires keeping an inverted dependency graph, which can be quite expensive memory-wise. In a project like chromium there are ~40k translation units, and it is safe to assume there are ~1k core headers just coming from std library, that are most likely included by all of the translation units directly or transatively. This results in ~320MB of memory usage even if we just store a pointer.
It is quite likely that there would be a lot more "base" headers like that, which could easily drive up the memory usage. We might need some tradeoffs to limit that usage.
