Yes, oe-core supports hard-float tunings, see the various TUNE_FEATUREs defined in meta/conf/machine/include/tune*.inc. It's never been entirely obvious whether this is actually very much of a win in practice though, unless your workload is extraordinarily FP-intensive. p.

I strongly discourage people from using it. If you don't care about ABI compatibility it might be a few cycles faster.. but it does limit your ability to draw from existing EABI software.

If you don't care about = ABI compatibility it might be a few cycles faster.. The issue with hf isn't technical, it's that projects like debian and = ubuntu are hyping it.

I discussed that at length during my job interview at TI about 3 years = ago, we're finally seeing the problem in real life :) regards, Koen=
