Are those coming from arch.rs? If so, please move them to a new file to not clutter this one. Also mention in this new file that those were auto-generated in the past and should not be edited manually.

I was hesitating to do that so definitely agree. :)

Shouldn't this be:
Suggested change
| let Some((arch, name)) = name.split_once('.') else { unimplemented!("***** unsupported LLVM intrinsic {}", name) }; | |
| let Some((arch, name)) = name.split_once('.') else { unimplemented!("***** unsupported LLVM intrinsic llvm.{}", name) }; |

Indeed, good catch.

Taking over #580.
I copied all intrinsics generated from old
llvmintandllvmint2repositories directly intollvm.rs, so only remains the actual LLVM intrinsics.
