In practice, however, I have not seen this kind of optimising as of yet. Maybe on ARM there is no gain in performance. Unless there is a proper (read: for all ARM architectures, and working like we know it from powerpc-linux) -msoft-float patch for GCC 3, I'm inclined to just (carefully) drop -msoft-float from *boot.
How do you handle the ARM variants which have a hardware FPU then? I didn't work with a cpu which has one yet, but there are some out there.
I'm curious about Robert Schwebel's assessment of this issue, since I know he's been workin on this.
We should probably discuss that on crossgcc as there are others like Benedikt Spranger, Marc Kleine-Budde and Dan Kegel, who may give better comments on this than me, I didn't have time to investigate the problem further than trying Nico's patch and integrate it into PTXdist.
