  29  * This file generates all the gl* function entrypoints.  This code is not
  30  * used if optimized assembly stubs are available (e.g., using x86/glapi_x86.S
  31  * on IA32 or sparc/glapi_sparc.S on SPARC).

  33  * \note
  34  * This file is also used to build the client-side libGL that loads DRI-based
  35  * device drivers.  At build-time it is symlinked to src/glx/x11.
