- *
- * Standalone test for optimization passes.
- *
- * This file provides the "optpass" command for the standalone
- * glsl_test app. It accepts either GLSL or high-level IR as input,
- * and performs the optimiation passes specified on the command line.
- * It outputs the IR, both before and after optimiations.
