Can anyone give me any pointers on how to use the -mpaired option ("PowerPC
750CL paired-single instructions") ? I'm trying to get it to use the
reduc_s{min,max,plus}_v2sf patterns in gcc/config/rs6000/paired.md, so far I
haven't managed to find a configuration that supports loading a vector of floats
but that doesn't also have superior altivec/v4sf support...
Thanks, Alan
