the crweird group is extremely powerful manipulation of CR Fields
and needs implementing. Scalar first, SVP64 may be a separate
toshaan the pseudocode in draft form is designed already, the
insteuctiins themselves designed already, it is a matter of
nailing down the fields.txt (power isa book I section 1.6)
the CSV files (microwatt style decoder) writing the pseudocode
and writing the unit tests. the IRC discussion was here
which gives so many other examples when things were added that it
really should be a "by-the-numbers" task, now. we can add a paid
task if you are interested in updating the wiki
pseodocode best in its own new subfile although a case could be
made for adding them to condition.mdwn the fact that mtcr etc
are not in that but are in the system chapter of Power ISA...
the ones involving RT-CRs need a workaround in
ISACaller, i will have to handle that, but the actual scalar
implementation is dead-straightforward.
toshaan i have been editing this page so as to create ls015
also needed the two Forms as part of the RFC so that bit is done.
