To be honest I don't understand your problem.
You compile with hard float, you don't have a floating point unit, you enable a
kernel feature + debugging to fixup the mess.
Your options:
- Move to VFP and an arm core that has that
- Disable NWFPE and implement fixed point integer arithmetic for
JavaScript
- Build your gcc with -msoft-float to automatically use Nicola's fixed
point
integer code for every operation...
what am I missing?
