From: jochen@chromium.org Date: Wed, 2 Jul 2014 14:00:16 +0000 (+0000) Subject: Make flag definition macros style guide compliant and clang-format it. X-Git-Tag: upstream/4.7.83~8416 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=df6e1ac69e98ad016f9ed7e5c1a8a8d82b2d55ed;p=platform%2Fupstream%2Fv8.git Make flag definition macros style guide compliant and clang-format it. coding style wants macros to be all upper case, and so clang-format only detects those as macros.
