102 /* NOTE: Builtin functions which are used in the BUILTIN* opcodes must
103 * have a BUILTIN_... macro defined as seen below. In code dealing
104 * with the BUILTIN* opcodes the functions may only be addressed by
105 * these macros, never by their actual name! (This helps to make this
106 * code more portable.)
108 * C and assembler code which does not deal with the BUILTIN* opcodes,
109 * can use the builtin functions normally (like all other functions).
112 * For each builtin function which is used in a BUILTIN* opcode there
113 * must be an entry in the builtin_desc table in jit/jit.c.
115 * Below each prototype is either the BUILTIN_ macro definition or a
116 * comment specifiying that this function is not used in BUILTIN*
119 * (The BUILTIN* opcodes are ICMD_BUILTIN1, ICMD_BUILTIN2 and
