-## SVP64Single in SFFS
-
-important note: SFFS implementations that don't implement SVP64 can still
-implement EXT2xx instructions by using the SVP64Single encoding with SVRM=0,
-no other SVP64 state needs to be implemented to do that.
-(TODO: double check that)
-
-## full table
-
-note: I mostly stashed stuff in EXT2xx, so the scalar 32-bit space is still
-mostly free, most the instructions I wanted in the scalar 32-bit space took
-up too much room. I didn't allocate XO values in EXT2xx yet since there's
-plenty of space (32 POs equivalent)
-
-note: setvl is split into a 32-bit insn with a common subset of settings and
-a full 64-bit insn with all the settings; svstep is 32-bit
-
-note: fmv/fcvt are 32-bit ops, so you can see how they easily fit around bits
-26-29 which are used to distinguish from SVP64 prefixes.
