From: "glisse at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/55180] Missed optimization abs(-x) -> abs(x) Date: Fri, 02 Nov 2012 16:12:00 -0000 [thread overview] Message-ID: <bug-55180-4-OQ0sNVY1HV@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-55180-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55180 Marc Glisse <glisse at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |DUPLICATE --- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> 2012-11-02 16:11:43 UTC --- Thanks, I had missed that one. ABS_EXPR is a bit special in that it has its own tree code, instead of appearing as a call to a builtin function, but the issue is the same indeed, the optimization is there but can never be applied. *** This bug has been marked as a duplicate of bug 16107 ***
