This is correct. This is a bug in the Intel documentation. HJ, can you
report this internally within Intel to get the docs fixed?
Additionally, I noticed that the class pr-readers-nobr-nomovpr contains
fp-non-arith in addition to xma and xmpy which is redundant. The xma
and xmpy could be deleted here. This is a harmless error though.
I wrote a patch to fix gas. I just fixed the fp-non-arith problem, I
didn't bother with the other one as it doesn't matter. With this patch,
I now get the following objdump -d output for the assembled testcase,
which is correct.

When regenerating ia64-asmtab.c, I noticed that a newline was
accidentally deleted when the copyright messages were updated, so I
included that in my patch too.
The patch was tested with make check on an x86_64-linux host and checked
