Public bug reported: Binary package hint: gcc
On 32bit Ubuntu, all packages (except gcc and kernel) are compiled for the i386/i486 instruction set, thus losing out on the speed benefits targeting i586 gives. This brings new instructions and better instruction scheduling. Fedora 11 have implemented this move: https://fedoraproject.org/wiki/Features/ArchitectureSupport There are two ways to accomplish this - either via a patch to the gcc-4.4 package, to pass '--target=i586-gnu-linux' to the 'configure' script, or changing the default package build options via inheriting 'CFLAGS="-march=i586"'. ** Affects: gcc-defaults (Ubuntu) Importance: Undecided Status: New -- application performance loss (32bit ubuntu)... https://bugs.launchpad.net/bugs/379054 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
