URL: http://llvm.org/viewvc/llvm-project?rev=348328&view=rev Log: [clang-query] Continue if compilation command not found for some files When searching for a code pattern in an entire project with a compilation database it's tempting to run ``` clang-query **.cpp ``` And yet, that often breaks because some files are just not in the compilation database: tests, sample code, etc.. clang-query should not stop when encountering such cases.
