llvm/test/tools/llvm-cov/Inputs/README

-These inputs were pre-generated to allow for easier testing of llvm-cov.
-
-test.gcno and test.gcda were create by running the latest version of clang:
-  clang++ -g -ftest-coverage -fprofile-arcs test.cpp
-
-test.cpp.gcov was created by running gcov 4.2.1:
-  gcov test.cpp
