--- Comment #6 from Alexandre Oliva <oliva at gnu.org> ---
thanks for the crash course.  as I said in the call, it was very useful.
it's all beginning to make sense.

> we can "get away with this" by specifying the mode-type as part of the
svp64 encoding... for now.

I was going to ask about that.  it seems that there's nothing in the svp64
prefix instruction itself that tells how to decode its fields, you have to look
at the actual insn that follows to know.

Once we get to a stage in which we'll want to specify svp64 fields separately,
rather than combined into a 24-bit immediate, an explicit specification of mode
may help the assembler, to some extent, but the disassembler (and the
assembler, if it's to detect inconsistencies) will have to look at prefix+insn
as a single thing to be able to do its job.
