Author: omtcyfz Date: Mon Aug 1 12:15:57 2016 New Revision: 277356 URL: http://llvm.org/viewvc/llvm-project?rev=277356&view=rev Log: [clang-rename] handle overridden functions correctly
1. Renaming overridden functions only works for two levels of "overriding hierarchy". clang-rename should recursively add overridden methods. 2. Make use of forEachOverridden AST Matcher. 3. Fix two tests.
