From: "segher at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/103316] PowerPC: Gimple folding of int128 comparisons produces suboptimal code Date: Fri, 19 Nov 2021 17:34:19 +0000 [thread overview] Message-ID: <bug-103316-4-jUCEqCSbYV@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-103316-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103316 --- Comment #12 from Segher Boessenkool <segher at gcc dot gnu.org> --- When is the lowering done currently? Only for the ops that have no other way of doing, and things are merged back to an __int128 immediately after that? If that is what is going on, then that is unfortunate, but it may the best we can do yes. Sigh.
