29 * This file generates all the gl* function entyrpoints.
30 * But if we're using X86-optimized dispatch (X86/glapi_x86.S) then
31 * each of the entrypoints will be prefixed with _glapi_fallback_*
32 * and will be called by the glapi_x86.S code when we're in thread-
33 * safe mode.
34 *
35 * Eventually this file may be replaced by automatically generated
36 * code from an API spec file.
37 *
38 * NOTE: This file should _not_ be used when compiling Mesa for a DRI-
39 * based device driver.
