Hi Kanad,
We’ve been working on soft FPU support for LEON 3 and 4 and Sparc generally. It’s not ready for the big-time yet, and not our focus this week, but we’ll be trying to iron-out the problems and get that into the codebase soon.
If you need, you can send me a personal email if you want to get involved or see if we can work together to build on what we already have.
Best Regards,
Chris Dewhurst, University of Limerick.
