A compilation database that returns a single compile command line.
Useful when we want a tool to behave more like a compiler invocation. This compilation database is not enumerable: getAllFiles() returns {}.

Returns the given compile command.
Will always return a vector with one entry that contains the directory and command line specified at construction with "clang-tool" as argv[0] and 'FilePath' as positional argument.
Implements clang::tooling::CompilationDatabase.

Creates a FixedCompilationDatabase from the arguments after "--".
Parses the given command line for "--". If "--" is found, the rest of the arguments will make up the command line in the returned FixedCompilationDatabase. The arguments after "--" must not include positional parameters or the argv[0] of the tool. Those will be added by the FixedCompilationDatabase when a CompileCommand is requested. The argv[0] of the returned command line will be "clang-tool".
Returns NULL in case "--" is not found.
The argument list is meant to be compatible with normal llvm command line parsing in main methods. int main(int argc, char **argv) { std::unique_ptr<FixedCompilationDatabase> Compilations( FixedCompilationDatabase::loadFromCommandLine(argc, argv)); cl::ParseCommandLineOptions(argc, argv); ... }
Argc | The number of command line arguments - will be changed to the number of arguments before "--", if "--" was found in the argument list. |
Argv | Points to the command line arguments. |
ErrorMsg | Contains error text if the function returns null pointer. |
Directory | The base directory used in the FixedCompilationDatabase. |
