the projectpreference is for using git.libre-soc.org - remember you only have
to ask https://git.libre-soc.org/?p=simplev-cpp.git;a=summary

feel free to help to turn svp64.py parsing into parameterised functions
(i will make a start this morning before you're up, US time).  both you,
alexandre, and other people in the future will need it to do the
auto-generation of svp64 "field interpretation", particularly the
EXTRA2/3 fields.

it's rather unfortunate that there's not enough bits free in the 24-bit RM
extra to actually say what format the EXTRA2/3 fields are, meaning it has
to be obtained by looking at what the actual opcode is.

at some point PowerDecoder will have to do the same trick.
