From: "glisse at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/100929] gcc fails to optimize less to min for SIMD code Date: Mon, 07 Jun 2021 06:02:36 +0000 [thread overview] Message-ID: <bug-100929-4-ZwFnwLORnq@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-100929-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100929 --- Comment #4 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Denis Yaroshevskiy from comment #3) > Is what @Andrew Pinski copied enough? I think so (it is missing the command line), although one example with an integer type could also help in case floats turn out to have a different issue. > -ftrapping-math causes clang to stop doing this optimisation. Note that -ftrapping-math is on by default with gcc (PR 54192), but -fno-trapping-math wouldn't solve your problem, we are missing other things.
