ORFPX32 instruction support in or1ksim #47

Hello, I noticed that some hard-float instructions are not implemented in or1ksim and I couldn't find the source code related to ORFPX32 instructions. I'm wondering if I miss anything.

Hi Jungsook,<br> <br> You are correct. Or1ksim only implements the core ORBIS32 instruction set at present.<br> <br> I don't believe implementing the ORFPX32 single precision FP instructions would be very difficult. Mostly extending cpu/or32/insnset.c (this file is processed to generate execgen.c, using the program in cpu/or32/generate.c).<br> <br> If you wish to contribute this functionality, it would be very welcome.<br> <br> Jeremy

Dear Jeremy,
Thank you very much for your quick response. I'll try to implement it.

Jungsook's implementation is in SVN and will be part of the forthcoming 0.4.0 release.

Marking as fixed.
