[libc-commits] [PATCH] D114301: [libc] update tidy rules to fix variable formatting

[Michael Jones via Phabricator via libc-commits]

michaelrj updated this revision to Diff 391157.
michaelrj added a comment.

add an exception for src/__support/CPP because it's supposed to match external code and thus might not match the internal format.
