Re: NetBSD on SH-4A

["David S. Alessio" <David%SysRealTime.com@localhost>]

Hello,

I'd like to see the SH-4A fully supported.  Any suggestions on the best 
path to get there?

The approach that first comes to my mind is:
1)   Add kernel support for the FPU to the SH-4 arch
   Has anyone examined this?  If so, any thoughts/suggestions on the 
"right way" to do it?
   I'd like to see a lazy FPU context switch.

2)  Recompile the SH-4 world with FPU support
   (gcc default integer division should not use the FPU)

3)  Add support for SH-4A 32-bit addressing.

4)  Rebuild the SH-4A world.

Cheers,
-david
