In GCC v3.2.x, what is the difference in code generation between the
"-march=k6-3" and "-march=k6-2" options?
My understanding is that the only difference between these CPUs is that
the K6-3 has an L2 cache, where the K6-2 does not. Is the difference
between these -march option just exploiting that cache, or is there more
to the code generation than that?
Thanks.
