From: "dominiq at lps dot ens dot fr" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug fortran/44773] [4.6 Regression] Unnecessary temporaries increase the runtime for channel.f90 by ~70% Date: Fri, 09 Jul 2010 12:02:00 -0000 [thread overview] Message-ID: <20100709120203.32200.qmail@sourceware.org> (raw) In-Reply-To: <bug-44773-12313@http.gcc.gnu.org/bugzilla/> ------- Comment #15 from dominiq at lps dot ens dot fr 2010-07-09 12:02 ------- The patch in comment #10 avoids the extra temporaries and recovers the original timings. Regstrapped without regression and passed my tests. Note also that it "fixes" pr44744. Concerning the test in comment #13 it gives 3.0 with/without the patch (as well with g95). I don't know if it should give 1.0 (the value before "call bar(u)") or not, but the result does not depend on the patch. Thanks for the quick fix. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44773
