f9cc6acbfa6f6f91b29a0601436d91a330fdce79 is the first bad commit commit f9cc6acbfa6f6f91b29a0601436d91a330fdce79 Author: Brian Paul <brianp@vmware.com> Date: Wed Apr 27 09:31:30 2011 -0600 st/mesa: raise shader MaxParameters if driver supports more The default value is 64 but drivers usually advertise more, like 4096. Allows ARB vp/fp programs to use more parameters.

I've posted a patch for review to the piglit list. This should be fixed by the following piglit commit: commit c19366f77895608bc4cd0e6b3bbc92b6b17f2c29 Author: Ian Romanick <ian.d.romanick@intel.com> Date: Tue Aug 30 11:05:41 2011 -0700 vp-max-array: Exercise GL_MAX_PROGRAM_PARAMETERS_ARB with a contant array This eliminates the dependency on GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB. In particular, this makes the test run correctly on implementations where GL_MAX_PROGRAM_LOCAL_PARAMETERS_ARB is less than GL_MAX_PROGRAM_PARAMETERS_ARB.
