From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/110252] [14 Regression] Wrong code at -O2/3/s on x86_64-linux-gnu Date: Thu, 15 Jun 2023 03:11:09 +0000 [thread overview] Message-ID: <bug-110252-4-x61ffpDzHM@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-110252-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110252 --- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- here is another testcase which is reduced from sel-sched.cc which we currently miscompile: ``` [[gnu::noipa]] int g(int min_need_stall) { return min_need_stall < 0 ? 1 : ((min_need_stall) < (1) ? (min_need_stall) : (1)); } int main(void) { for(int i = -100; i <= 100; i++) { int t = g(i); if (t != (i!=0)) __builtin_abort(); } } ``` Note g really could be reduced down to (min_need_stall != 0) but we don't do that currently (nor does clang).
