Re: spring and -march=i686

Has anyone done any benchmarking/testing to see if -march=686 makes
any difference?

I suspect the GPU probably matters more than the CPU?

Usually binaries have to work on the base CPU instruction set for an
architecture, IIRC that is 486-level instructions for i386. I imagine
detecting CPU support for SSE at runtime is an acceptable way to make
one set of binaries.
