Subject: [Bug c/37591] suppress "signed and unsigned" warnings when signed value known to be positive
Date: Fri, 19 Sep 2008 20:56:00 -0000 [thread overview]
Message-ID: <20080919205528.6853.qmail@sourceware.org> (raw)
In-Reply-To: <bug-37591-37@http.gcc.gnu.org/bugzilla/>
------- Comment #1 from pinskia at gcc dot gnu dot org 2008-09-19 20:55 -------
I think this needs to delay the warning until VRP time really but I don't see
how that can be done really.
Also the front-end does known that adj will only be positive, the middle-end
only knows during VRP really.
