Inquiry on Zentool Instruction Coverage and Symbol-to-ROM Mapping

Hi,
I was wondering if you have evaluated microcode patches for instructions other than RDRAND? I'm curious whether Zentool provides (or can generate) a canonical list of instructions eligible for patching on Zen2 or 4.

Additionally, when writing a patch, I see the 'edit' command accepts symbolic targets (e.g., --match 0=@rdrand) instead of raw ROM addresses. Is there a way to trace an instruction to its microcode footprint (ROM or RAM addresses), or a reference (e.g., symbol table, etc.) that maps each @ to its corresponding ROM address or entry index for match-register configuration?

Thanks,
