So actually I'm gravitating towards calling all that instruction
"massaging" code with a single prefix to denote this comes from the insn
decoder/handler/whatever...
I.e.,
"insn-decoder: x86: invalid register type"
or
"inat: x86: invalid register type"
or something to that effect.
I mean, If we're going to grow our own - as we do, apparently - maybe it
all should be a separate entity with its proper name.
Hmm.
