You can achieve the same as a .clang-format-ignore for vendored directories by putting a .clang-format in those directories which turns off formatting (IIRC, this takes two lines). What's more, this works with old versions of clang-format!

We recently had a suggestion about introducing a .clang-format-ignore file, it seems there could be value in that for areas of which you don't want to ever format. Anyone undertaking a global clang-format without prior knowledge of the specific area wouldn't necessarily know that.

You have no other choice. Polly verifies its source formatting as part of check-polly, so every commit that violates formatting will get an email from the buildbot.It also triggers when clang-format itself changes. Did you find those helpful? The parts of Polly that are left out are its external dependencies, i.e. isl and imath. I wonder why these are even included in the clang-format status, we certainly do not want to modify these source files. For clang, I have to exclude the test folder because clang-format messes with clang -verify tests that require comments on specific lines and tests that check correct behavior of clang on whitespace.
