For those familiar with FSF's <strong>gcc</strong> tool, it is very similar. Please note that <strong>llvmc</strong> is considered an experimental tool.</p> <p> </p> <hr /> <h1><a name="options">OPTIONS</a></h1> <p> </p> <h2><a name="built_in_options">Built-in Options</a></h2> <p>LLVMC has some built-in options that can't be overridden in the configuration libraries.</p> <dl> <dt><strong><a name="o_filename" class="item"><strong>-o</strong> <em>filename</em></a></strong></dt> <dd> <p>Output file name.</p> </dd> <dt><strong><a name="x_language" class="item"><strong>-x</strong> <em>language</em></a></strong></dt> <dd> <p>Specify the language of the following input files until the next <strong>-x</strong> option.</p> </dd> <dt><strong><a name="load_plugin_name" class="item"><strong>-load</strong> <em>plugin_name</em></a></strong></dt> <dd> <p>Load the specified plugin DLL.

Because of plugins, these checks can't be performed at compile-time. Exit with code zero if no errors were found, and return the number of found errors otherwise. Hidden option, useful for debugging LLVMC plugins.</p> </dd> <dt><strong><a name="view_graph" class="item"><strong>--view-graph</strong></a></strong></dt> <dd> <p>Show a graphical representation of the compilation graph and exit.

This option can also take an argument: the <em>--save-temps=obj</em> switch will write files into the directory specified with the <em>-o</em> option.

A whitespace character may be included in an option by surrounding the entire option in either single or double quotes.
