[PATCH] D75323: Support relative dest paths in headermap files

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

I don't know why we (chromium) want to use header maps, but assuming we do want to use them: The problem with absolute paths is that they're machine-dependent and can't be run on other machines and then cached globally.
