From: "spop at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/43423] gcc should vectorize this loop through if-conversion Date: Thu, 08 Apr 2010 17:47:00 -0000 [thread overview] Message-ID: <20100408174705.9235.qmail@sourceware.org> (raw) In-Reply-To: <bug-43423-18740@http.gcc.gnu.org/bugzilla/> ------- Comment #6 from spop at gcc dot gnu dot org 2010-04-08 17:47 ------- I changed the title of this bug to match the comments in the PR: we should vectorize this loop using if-conversion, and not "iteration range splitting". Also note that in general, by doing an "iteration range splitting" the data locality in the two loops could be worse than in the if-converted loop. -- spop at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|gcc should vectorize this |gcc should vectorize this |loop through "iteration |loop through if-conversion |range splitting" | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43423
