            Bug ID: 105105
           Summary: Suffixless KHR_robustness functions aren't exposed in
                    ES 3.2
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: kenneth at whitecape.org
        QA Contact: mesa-dev at lists.freedesktop.org
                CC: idr at freedesktop.org

These two tests fail on i965:

   KHR-NoContext.es32.robustness.readnpixels
   KHR-NoContext.es32.robustness.getnuniform

The readnpixels test does:

   PFNGLREADNPIXELS pReadnPixels =
(PFNGLREADNPIXELS)context->getRenderContext().getProcAddress("glReadnPixels");

and then calls that function pointer...but ends up in generic_nop().

It looks like the suffixless versions aren't getting exposed correctly, despite
being part of ES 3.2.

There's a fair bit of complex aliasing going on for ARB/KHR/suffixless, and I'm
getting a bit lost trying to figure out the right mapi/glapi/gen XML snippets
to do the right thing.
