Well it worked, so it wasn't broken. I would just have liked this
instruction to be fixed in a backwards compatible way (e.g. warning - or
is it just a warning and my gcc flags treat them as errors?).

Huh?

PoP - "Control Instructions" - 10-176 - "TEST BLOCK". Even can find it
in the Pop from 2004.

But anyhow, we have this fixed now. Was just wondering, why our
_working_ code suddenly broke (and now we have to use .insn to make it
compile with GCC in general).

Thanks.
