Subject: use the CSV "CR out" column to compute which mode to use for Rc=1
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=de103f942c8fe5f284e41125f17759e242762924;p=openpower-isa.git

use the CSV "CR out" column to compute which mode to use for Rc=1

this works much better than trying to bodge it by checking if the
instruction name meets some pattern
