From: "gabravier at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/102224] Incorrect compile on `x * copysign(1.0, x)` Date: Tue, 07 Sep 2021 03:01:54 +0000 [thread overview] Message-ID: <bug-102224-4-bCz0OlZKvr@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-102224-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102224 --- Comment #3 from Gabriel Ravier <gabravier at gmail dot com> --- Also seems like this might be unique to x86 as this compiles fine on Aarch64 (though while it doesn't try to do anything stupid like xoring the result with itself, it does still not optimize the XOR_SIGN to an ABS_EXPR at the GIMPLE level).
