[PATCH] D91908: [clang-tidy] Use compiled regex for AllowedRegexp in macro usage check

[Nathan James via Phabricator via cfe-commits]

While I'm a fan of this change, I think this is the wrong way to do it. Leave the check the same, but build the regex in the pp callback constructor. That should only get called once for the lifetime of the check.
