[PATCH] D87253: [libTooling] Change CDB heuristic to look further for files in a given language.

[Kadir Cetinkaya via Phabricator via cfe-commits]

kadircet added a comment.

As discussed offline, this is trading off some accuracy between getting `-I` correct vs `-std` and it is unclear whether that's beneficial or harmful. It is easy to come up with examples for both and we were split 50/50 between each.
In the end all of this is a heuristic work and it is quite likely that we might break this for more people, while trying to fix this one specific case. So I don't think it's worth it.

As for suggestions(again from offline discussion) :

- We can implement a more sophisticated transfer logic in clangd layer, by making use of compile commands from a TU including a particular header
- When there's a mismatch in language, we can try to merge two commands. One with filename/path match and filetype match.
