Adding new instruction

[WeissAviram]

Hi,
As part of my project I need to add 2 new instructions to the riscv core.
I don't find the file in which the opcodes are defined (in the SW toolchain) and I've been searching that for long time.
Can I get the path please for this file? or Alternativly, can I get the steps and files names for adding these 2 new instruction?

Thanks!

@WeissAviram This is rather out of the scope of this repository (hence why I didn't reply quicker). You might find this talk at the London RISC-V meetup helpful: https://youtu.be/GcnkcK3uYYI
