"The instruction set supported by the core is a combination of Intel Pentium® processor, AMD Athlon processor, and AMD Geode LX processor specific instructions. Specifi- cally, it supports the Pentium, Pentium Pro, AMD 3DNow! technology and MMX instructions for the AMD Athlon processor. It supports a subset of the specialized AMD Geode LX processor instructions including special SMM instructions. The CPU Core does not support the entire Katmai New Instruction (KNI) set as implemented in the Pentium 3. It does support the MMX instructions for the AMD Athlon processor, which are a subset of the Pentium 3 KNI instructions." -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41989
