[Mesa-dev] [PATCH 3/3] mesa: Always generate GL_INVALID_OPERATION in _mesa_GetProgramBinary

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

There are no binary formats supported, so what are you doing?  At least
this gives the application developer some feedback about what's going
on.  The spec gives no guidance about what to do in this scenario.
