Hi list, my laptop's cpu is AMD Turion64x2, I've installed both 32bits Debian testing and Gentoo on it, from Debian there is no SSE3 in /proc/cpuinfo, and I used CFLAGS="-O2 -march=athlon-xp -fomit-frame-pointer -pipe" on gentoo, and I can not see SSE3 in cpuinfo also,
I emerged x86info, and SSE3 is in its output: #x86info x86info v1.21. Dave Jones 2001-2007 Feedback to <[email protected]>.
