From: "pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/15458] Combine ~ and ^. Date: Wed, 30 Nov 2005 17:32:00 -0000 [thread overview] Message-ID: <20051130173235.30049.qmail@sourceware.org> (raw) In-Reply-To: <bug-15458-5009@http.gcc.gnu.org/bugzilla/> ------- Comment #4 from pinskia at gcc dot gnu dot org 2005-11-30 17:32 ------- Actually it is better for ~(a ^ CST) to come out as a ^ ~CST. Right now we actually already implement ~(a^CST) as a ^ ~CST. So we need just to implement (~a) ^ CST as a ^ ~CST. In fact this is what simplify_rtx does. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15458
