If Ghidra was really good, they wouldn't have had to release the source to it. ;)

It's Java, so it's not all that hard to reverse engineer.

Amazing. Just what I needed today, when I was writing OpenRisc processor definition for sleigh. :)

What's sleigh?

The decompiler is in c++.

Sleigh is the processor specification tool for Ghidra. He’s making it so that Ghidra can work with OpenRISC.

I believe this has now been released.

It’s “a machine language translation and disassembly engine”: https://ghidra-decompiler-docs.netlify.com/sleigh.html

What's the difference between OpenRisc and RISC_V?

I don't know. I've only came in contact with some old OpenRisc core, via Allwinner SoCs so far and no RISC-V cpus.

In two weekends I've come from no support for OpenRisc at all to this:
