Does anyone know which kind of x86-type the AMD LX 800 belongs to? 686?

The AMD Geode LX700@0.8W processor delivers great performance at lower power for value, embedded applications, and further extending battery life for mobile applications, while delivering full x86 functionality.

Sounded interesting, so I downloaded the datasheet...

The instruction set supported by the core is a combination
of Intels Pentium®, the AMD-K6® microprocessor and the
Athlon FPU, and the AMD Geode LX processor specific
instructions. Specifically, it supports the Pentium, Pentium
Pro, 3DNow! technology for the AMD-K6 and Athlon pro-
cessors, and MMX® instructions for the Athlon processor. It
supports a subset of the specialized 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 Athlon processor, which are a
subset of the Pentium 3 KNI instructions.

The amd tech sheet:

I never dealt with one of those, but, for what it seems, technically speaking, those cpus are just k6's with a low comsumption rate. So, you could use either "-march=k6" or "-march=i686 -mmmx -m3dnow". Chost would be 686, yeah. I would go along with k6, personally. You dont need to add 3dnow or mmx if you use k6, since a k6 is supposed to have this always, and it will be enabled automatically if you use -march=k6. |
