But you do not seem to understand what is_modulo means, even when you point to the LIA-1 part. Please, do consider the semantics described there and the quote I provided. Basically, you can decide that it overflows and send a notification of overlfow but "wrap" with defined meaning. -- Gaby -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22200
