--- Comment #9 from Jacob Lifshay <programmerjake at gmail.com> ---
I fleshed out dsld/dsrd:
https://git.libre-soc.org/?p=openpower-isa.git;a=commitdiff;h=a8332a548969f36d6e747c1b75735bc13194f8a9

and added unit tests for all bigint operations:

I added dsld/dsrd to minor_31.csv, but ran into issues when I attempted to
convert it to pattern mode -- apparently power_decoder.py suffix handling is
broken for patterns:
