Here're the minutes from our discussion, thanks for the comments you made. We added a last-minute topic as well, Andreas Building for i686 ================= Some comments on the situation: * some cpus have uname of i686 but do not support for the full i686 instruction set used by the compiler if compiling for i686, e.g. VIA Epia C3. * SUSE Linux runs on smaller systems as well, e.g. VIA boxes, for set top boxes and routers. * For most applications compilation on i686 will not make a speed difference for the user. * We optimize for i686 but use i586 instructions, the discussion is about using i686 instructions as well. * We already supply a few packages, e.g. glibc, for both i586 and i686. * We could add more packages as both i586 and i686. This is a question of size on ftp/media as well. * One way would be to switch at run-time between different code paths (one for i586, one for i686). * We should evaluate to setup i686 as an additional target in the build service for a couple of packages to rebuild with different compile flags. AI: Buildservice team to evaluate. We decided to stay as is for 32-bit x86 and use the i586 instruction since we would loose otherwise support for some existing hardware. Default compile flags: -O2 vs. -Os ================================== We run SPECcpu2000 benchmarks on x86-64 to compare -Os and -O2. The results are 1011 (-Os) and 1140 (-O2) for SPECint and for a subset of SPECfp 1202 (-Os) vs. 1270 (-O2), so the speed difference is too high to make this change. Overall .text size of all benchmarks: 6038603 (-Os) vs 6816414 (-O2) With filesize begin nearly exactly 1MB larger in both cases. We'll stay with -O2. Avahi and mDNSresponder ======================= We plan to use avahi by default and will drop mDNSresponder for openSUSE. Avahi has a mDNSresponder compatibility library so that no changes should be needed. We plan to concentrate on avahi since it has the better code. AI: AJ: Evaluate whether to do for openSUSE 10.2 or 10.3.
