Subject: clang-format: Improve pointer/reference detection.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8184d66f4b98d779abb5dd5564fb14157b5949d6;p=platform%2Fupstream%2Fllvm.git

clang-format: Improve pointer/reference detection.

Before (with left pointer alignment):
  void f(int i = 0, SomeType* *temps = NULL);

After:
  void f(int i = 0, SomeType** temps = NULL);
