Hi,
I just bought two machines with AMD Phenom II X4 black processors that are
supposed to be SSE3 and SSE4a capable but 'cat /proc/cpuinfo' shows only sse,
sse2 and ssse3. Also, compiling eigen programs with -msse3 flags (GCC)
results in illegal instruction runtime errors.
SSE3 == PNI (Prescott New Instructions)
google for: /proc/cpuinfo sse3
this also bugged me just recently ...
I'm not sure about the runtime error though. (I don't have a Phenom II)
