  26  *
  27  * Verify that only set of functions that should be available in a particular
  28  * API are available in that API.
  29  *
  30  * The list of expected functions originally came from the functions set by
  31  * api_exec_es2.c.  This file no longer exists in Mesa (but api_exec_es1.c was
  32  * still generated at the time this test was written).  It was the generated
  33  * file that configured the dispatch table for ES2 contexts.  This test
  34  * verifies that all of the functions set by the old api_exec_es2.c (with the
  35  * recent addition of VAO functions) are set in the dispatch table and
  36  * everything else is a NOP.
  37  *
  38  * When adding extensions that add new functions, this test will need to be
  39  * modified to expect dispatch functions for the new extension functions.
