Sorry, I disagree with this. As you said above rr would be the correct
format for this instruction. If we go for the e format then we should
also use an instruction with e format.
Which in this case would simply be an illegal opcode, which would be
sufficient for what this code is good for: ".insn e,0x0000".
Why not simply use .short then?
.short bypasses all sanity checks while .insn does not, so I think
that should be preferred. But I don't care too much.
Heiko,
I am fine with ".insn e,0x0000" and the a changed comment that changes "specification exception" to "operation exception".
Do you want Ilie to resend or simply fixup?
