40 * This file declares builtin functions that can be called from JITted code.
41 * Each line starts with "BUILTIN" and an integer, the number of arguments the
42 * builtin takes. Builtins with no arguments are not supported.
43 *
44 * The macro arguments are:
45 *
46 * - 'extern' to indicate extern linkage for these functions and the associated
47 * CallInfo.
48 *
49 * - The return type. This identifier must name one of the _JS_TYPEINFO_*
50 * macros defined in jsbuiltins.h.
51 *
52 * - The builtin name. Prefixed with "js_" this gives the native function name.
53 *
54 * - The parameter types.
55 *
56 * - The cse flag. 1 if the builtin call can be optimized away by common
57 * subexpression elimination; otherwise 0. This should be 1 only if the
58 * function is idempotent and the return value is determined solely by the
59 * arguments.
60 *
61 * - The fold flag. Reserved. The same as cse for now.
