--- Comment #4 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
https://git.libre-soc.org/?p=libresoc-isa-manual.git;a=blob;f=powerpc-add/src/SVPrefix.tex;hb=HEAD

it occurred to me that if we were to do SVPrefix by examining the fields.txt
and the Forms, we would literally be at it forever.

the technique developed by the microwatt team, to create micro-ops, has
*already*
done that analysis, and we hold that information in CSV files.

therefore if we instead do the analysis of which prefix is needed based on
the *CSV* files we save a vast amount of time.

it may also be possible to partially (or completely) automate the process
of determining the prefixes.
