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