From: "hubicka at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/45791] Missed devirtualization Date: Tue, 14 Dec 2010 23:17:00 -0000 [thread overview] Message-ID: <bug-45791-4-s5Kj8SoTtC@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-45791-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45791 --- Comment #10 from Jan Hubicka <hubicka at gcc dot gnu.org> 2010-12-14 23:17:13 UTC --- Eh, wanted to paste: D.2236_10 = (int (*__vtbl_ptr_type) (void)) f; OBJ_TYPE_REF(D.2236_10;D.2215_3->2) (D.2215_3); I told ccp should IMO optimize it, but doesn't. I guess it is because VRP1 works out the constant but then it doesn't know about OBJ_TYPE_REF folding.
