- * This file generates all the gl* function entyrpoints.
- * But if we're using X86-optimized dispatch (X86/glapi_x86.S) then
- * each of the entrypoints will be prefixed with _glapi_fallback_*
- * and will be called by the glapi_x86.S code when we're in thread-
- * safe mode.
+/**
+ * \file dispatch.c
*
- * Eventually this file may be replaced by automatically generated
- * code from an API spec file.
+ * This file generates all the gl* function entrypoints. This code is not
+ * used if optimized assembly stubs are available (e.g., using x86/glapi_x86.S
+ * on IA32 or sparc/glapi_sparc.S on SPARC).
*
- * NOTE: This file should _not_ be used when compiling Mesa for a DRI-
- * based device driver.
+ * \note
+ * This file is also used to build the client-side libGL that loads DRI-based
+ * device drivers. At build-time it is symlinked to src/glx/x11.
