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