Hi @taqtiqa-mark !
I'm personally not familiar with those specific variants, but if you can generate LLVM assembly (AT&T asm syntax) using rv32imac ISAs our powdr-rs crate should be able to compile it to powdr-IR using the asm
input.
As I see in the script you linked, it looks like it also generates a rv32ima ELF. Although our ELF frontend only supports rv32im, it's in general possible to remove the atomic instructions by using passes=loweratomic
.
It'd be great to have a look at any specific assembly or ELF files you're interested in, otherwise we can have a look ourselves at some point (it'll just take a bit longer).
Are any of the following open-source CPUs targets for powdr?
Specifically, should I ever expect that powdr will run on, say, the Berkeley/SiFive Rocket rv32ima, etc
