As mentioned, if DSPr1 and DSPr2 can't be distinguished at runtime, then
I don't think it makes sense to do runtime detection at all.

I didn't read all of the assembly since I'm not very familiar with MIPS
assembly, but the parts I did read looked good to me, so if you send
another version of the first patch addressing the -mdspr2 and runtime
detection issues, I'll push both patches.


Thanks,
