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