cbo Intrinsic

Is there a plan to add cbo Intrinsic
to the doc

I think nobody is working on this.
So, a PR would be appreciated!

Just a note to ensure we're all on the same page. The linked commit defines __builtin_riscv_* functions which so far have been considered out of the scope of this document (though I think we typically try to match what gcc does in LLVM). So if it's desirable, perhaps the path forward is to define a __riscv_* intrinsic that could be standardised.

(Christoph / Kito / ... - please correct me if wrong!)

Yes, I was expecting to get a PR that would follow the naming convention in the document. Thanks for stating this clearly!

Thanks my expectation as well :)

Might you know if those intrinsics are a wip in LLVM? There seems to be only assembly support for Zicbom, and I couldn't find a PR or issue regarding implementing these.

Nobody's posted a PR to my knowledge, and I'm not aware of anyone working on them so far. Patches welcome!

I try to send a patchset to upstream.
My work based on doc.
