 * The translator emits calls to builtins exactly the same way it
 * emits calls to functions written in the systemtap language; the
 * only difference is that this file (or a C tapset) must supply the
 * definition.
 *
 * Every builtin function "foo" called by a systemtap script is
 * translated to a C call to a C function named "function_foo". This
 * is the function you must provide in this file. In addition, the
 * translator emits a 
 * 
 *  #define _BUILTIN_FUNCTION_foo_ 
 *
 * symbol for each such function called, which you can use to elide
 * function definitions which are not used by a given systemtap
 * script.
