/**
 * This file declares builtin functions that can be called from JITted code.
 * Each line starts with "BUILTIN" and an integer, the number of arguments the
 * builtin takes.  Builtins with no arguments are not supported.
 *
 * The macro arguments are:
 *
 * - 'extern' to indicate extern linkage for these functions and the associated
 *   CallInfo.
 *
 * - The return type. This identifier must name one of the _JS_TYPEINFO_*
 *   macros defined in jsbuiltins.h.
 *
 * - The builtin name. Prefixed with "js_" this gives the native function name.
 *
 * - The parameter types.
 *
 * - The cse flag. 1 if the builtin call can be optimized away by common
 *   subexpression elimination; otherwise 0. This should be 1 only if the
 *   function is idempotent and the return value is determined solely by the
 *   arguments.
 *
 * - The fold flag. Reserved. The same as cse for now.

 * NB: bool FASTCALL is not compatible with Nanojit's calling convention usage.
