hello list, after many years without a hardware upgrade, i'll be receiving my new computer next week: intel i7 920 cpu, 6 GB ram, asus p6t mobo.
i'm pretty excited, i imagine that at first i'll be shocked at the difference with the ancient machine i'm using now. now my question: searching a bit for the best compilation flags for this processor, i found this at gentoo-wiki: CHOST="x86_64-pc-linux-gnu" CFLAGS="-march=core2 -msse4 -mcx16 -msahf -O2 -pipe" CXXFLAGS="${CFLAGS}" (http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel) on the other hand, a thread at http://forums.gentoo.org says that the wiki page is outdated, and that -march=native should do the job without any further tweaks like -msse4 etc. any ideas from the list? best, lj
