From: "rguenth at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/99912] Unnecessary / inefficient spilling of AVX2 ymm registers Date: Tue, 27 Apr 2021 14:02:11 +0000 [thread overview] Message-ID: <bug-99912-4-E65s8hqnmy@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-99912-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99912 --- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> --- So with the latest patches I now see real spilling dominating (oops). I also see, on the GIMPLE level _64425 = (unsigned long) SR.3210_122492; _64416 = _64425 + ivtmp.5307_121062; _62971 = (double &) _64416; __builtin_ia32_maskloadpd256 (_62971, _61513); that is, dead masked loads (that's odd). There's also still some dead / redundant code from the abstraction to remove.
