109 * have a BUILTIN_... macro defined as seen below. In code dealing
110 * with the BUILTIN* opcodes the functions may only be addressed by
111 * these macros, never by their actual name! (This helps to make this
112 * code more portable.)
114 * C and assembler code which does not deal with the BUILTIN* opcodes,
115 * can use the builtin functions normally (like all other functions).
118 * For each builtin function which is used in a BUILTIN* opcode there
119 * must be an entry in the builtin_desc table in jit/jit.c.
121 * Below each prototype is either the BUILTIN_ macro definition or a
122 * comment specifiying that this function is not used in BUILTIN*
