# IGC API Options list
This is an auto-generated list of options gathered from [ApiOptions.td](https://github.com/intel/intel-graphics-compiler/blob/master/IGC/Options/include/igc/Options/ApiOptions.td) file using [LLVM TableGen](https://llvm.org/docs/TableGen/).
The "Kind" column describes the type of Option as defined in [OptParser.td](https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Option/OptParser.td#L24-L50) refer to it for further information.
