oh, one other thing that would help is: in the last column, in front
of (or after, doesn't matter) would be to include the byte index of
the instruction.

padd [0]
padd [1]

this will definitely highlight the weirdness of SV-P48 and show that
its EXTNNN byte needs to be in different locations if the 48b
instruction is hword-aligned or dword-aligned.
