1401 Mismatching error message is returned in *MISMATCH_DETAIL upon request,
1402 i.e. when MISMATCH_DETAIL is non-NULL. This avoids the generation
1403 of error message during the disassembling where error message is not
1404 wanted. We avoid the dynamic construction of strings of error messages
1405 here (i.e. in libopcodes), as it is costly and complicated; instead, we
1406 use a combination of error code, static string and some integer data to
1407 represent an error. */
