#21341: fixed packaging for gcc44 --------------------------------------+------------------------------------- Reporter: howarth@… | Owner: mww@… Type: enhancement | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.0 Keywords: | Port: gcc44 --------------------------------------+------------------------------------- Comment(by howarth@…): Keep in mind that currently graphite is of little use in gcc 4.5.x. Only in gcc 4.6 are we finally approaching the point where -fgraphite-identity doesn't actually degrade the vectorization achieved... http://gcc.gnu.org/ml/gcc-patches/2010-08/msg00159.html Also currently the higher level graphite optimizations don't achieve any improvements, however once the vectorization loses are eliminated for -fgraphite-identity that option might yield a few percent improvement. http://gcc.gnu.org/ml/gcc-testresults/2010-08/msg00666.html vs http://gcc.gnu.org/ml/gcc-testresults/2010-08/msg00556.html shows the missed vectorization on using -fgraphite-identity (which converts the gimple to polyhedral represemtations and then back again to gimple (hopefully providing a more accurate representation of the loops than the original gimple). -- Ticket URL: <http://trac.macports.org/ticket/21341#comment:20> MacPorts <http://www.macports.org/> Ports system for Mac OS
