minor nit because I see that very often. :) from the gcc man page:

       -march=cpu-type
           Generate instructions for the machine type cpu-type.
           The choices for cpu-type are the same as for -mcpu.
           Moreover, specifying -march=cpu-type implies
           -mcpu=cpu-type.

The extra -mcpu is unnesessery :). And theres a -mmmx switch, but I 
don't know if it is that useful for DSP, since the mmx instructions are 
integer only.
Good thing you didn't recommend -O3. I've seen instances where it was 
much slower than -O2.
