This patch applies clang-tidy's bugprone-argument-comment tool to LLVM, clang and lld source trees. Here is how I created this patch: $ git clone https://github.com/llvm/llvm-project.git $ cd llvm-project $ mkdir build $ cd build $ cmake -GNinja -DCMAKE_BUILD_TYPE=Debug \ -DLLVM_ENABLE_PROJECTS='clang;lld;clang-tools-extra' \ -DCMAKE_EXPORT_COMPILE_COMMANDS=On -DLLVM_ENABLE_LLD=On \ -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ../llvm $ ninja $ parallel clang-tidy -checks='-*,bugprone-argument-comment' \ -config='{CheckOptions: [{key: StrictMode, value: 1}]}' -fix \ ::: ../llvm/lib/**/*.{cpp,h} ../clang/lib/**/*.{cpp,h} ../lld/**/*.{cpp,h} llvm-svn: 366177
