Hi John,
Is there a particular reason why you cannot just include the textual
version of the opcode you want and have it assembled as normal ?
I'm trying to use a new cpu, but for various reasons, have not been able
to complete the switch to a newer toolchain [yet]. This
new cpu supports a handful of new instructions, including wfi, which we
wanted to exercise, but was not accepted by the older binutils.
Objdump refuses to disassemble those opcodes even with the

This has now been fixed in the mainline sources.
Great! I'm watching to see how the discussion on the pseudo-op concludes.
Thanks, John
