[Piglit] [PATCH 8/8] gl-3.0: Add test for the forward-compatible bit

Chad Versace chad.versace at linux.intel.com
Thu Dec 19 18:12:39 PST 2013


Create a context with or without the forward-compatible bit, according to
a command line flag.  Then verify that GL_CONTEXT_FLAGS does or does not
contain GL_CONTEXT_FLAG_FORWARD_COMPATIBLE_BIT.
