/*
 * 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.
 *
 * Eventually this file may be replaced by automatically generated
 * code from an API spec file.
 *
 * NOTE: This file should _not_ be used when compiling Mesa for a DRI-
 * based device driver.
