From: "rguenth at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/95960] GCC should re-vectorize vector code with larger VF Date: Mon, 29 Jun 2020 12:12:48 +0000 [thread overview] Message-ID: <bug-95960-4-2lC42IqPUS@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-95960-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95960 --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 48801 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48801&action=edit start So quick experiments show where we need to do adjustments. We do have an explicit SLP_TREE_LANES we could use for "true" scalar lanes as compared to the number of "scalar" stmts but uses might have been transitioned not exactly along this boundary. Then there's of course 'group_size' which can mean either depending on context. The biggest churn is likely in dataref group analysis where we IMHO also want a "lanes" representation.
