MIPS R4000 for the MSCoffLoader

[voyagerjuno]

So, as per my question in #9458, I implemented MIPS R3000/R4000 support for the MSCoffLoader.

It has some details that I personally don't like at all, like it's dependence on the file header state and preserving information between calls. I don't know if that practice is allowed or if it will be preserved in futures versions of ghidra, but it works as good as it can and is a consequence of both the way that MSCoff generated their object files, and me not knowing better.

I'm including the Relocation Handler(with it's path) and a file generated with CL.EXE for MIPS
MIPS_CoffRelocationHandler.zip

Thanks. Want to submit it as a pull request?

It will be nice. I'm not sure if my code follows the best practices but I suppose that is only one way to know

Hi @voyagerjuno

Just in case you haven't come across these, there a few MIPS ABI, R4000 and a pecoff.pdf documents at

That's awesome! I will read the documentation and double check if I must change something. I'm glad I haven't submitted a pull request yet.

Thanks!
