rright. apologies. i just realised i will need to use the above.
this is an intermediary analysis phase that combines svp64 EXTRA info with
the opcode CSV files to *extend* those CSV files with the identification
where in decode1.vhdl there is in1/in2/in3/out this must be joined by
sv_in1 sv_out etc. where that column specifies the sub-field index (0-3) of
SVP64 EXTRA info that must be read.
that index can then be used e.g. here:
to actually grab the right EXTRA2/3 which tells you that in1 for example
has been extended to Vector.
i will update sv_decode.vhdl shortly.
