Support for pseudoops

Open tobiasgrosser opened this issue 3 years ago • 3 comments

I just realized riscemu does not support seqz, snez, sltz and slez. These and the other pseudoinstructions documents in the RISCV manual would be really useful.

Great catch!

Some pseudonyms are already implemented, I think I'll ad a separate "instruction set" which contains all pseudonyms, so they can be included or excluded as needed.

So much real world code contains pseudoinstructions so this feature would be very useful. :)

Thanks for the poke @bjourne, this appears to be a relatively straight-forward thing to implement. I'm happy to give feedback on a PR on this, if anyone decides to tackle the problem, or implement it myself when I find the time.

I guess a good first step would be to get a list of all pseudoinstructions from the manual?
