ORFPX32 instruction support in or1ksim

Description:
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.

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

Hi Jungsook, You are correct. Or1ksim only implements the core ORBIS32 instruction set at present. 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). If you wish to contribute this functionality, it would be very welcome.
