| # Declares a GIDL library. |
| # |
| # This target generates binding specific tests or benchmarks from GIDL inputs. |
| # |
| # Parameters |
| # |
| # type (required) |
| # String indicating the type of generation. Currently "conformance" or "benchmark". |
| # |
| # language (required) |
| # String indicating the binding name. |
| # |
| # inputs (required) |
| # List of input GIDL files |
| # |
| # fidl (required) |
| # Name of the FIDL GN target that defines types used in the GIDL files. |
| # |
| # output (required) |
| # Path of the output file to generate (in the case of 1 output). In the case of multiple |
| # outputs, this is the name of an output file used to generate all output file names. |
| # e.g. a.cc, a2.cc, a3.cc... |
| # |
| # num_output_files (optional) |
| # Number of output files to generate. The same number of outputs are always generated |
| # to allow consistent dependencies in GN. If there are too many outputs, blank files will |
| # be written. This is used for C++ to shared the generated files for build performance |
| # reasons. |
| # |
| # all_outputs (optional) |
| # In the case of multiple outputs, this is the name of all generated output files. |
