I have discovered that the EMUL instruction on the CCI Power6/32
(aka Sperry 7000/40) does not work correctly. When I contacted
Sperry about this they said they would notify the appropriate
people at CCI.
Additionally they told me that the instruction CMPD2 does not
give correct results either.
EMUL cannot correctly calculate 1 * 1 + (-1)
and others with sign extended addends.
I am not sure of the exact problem with CMPD2 as I have not been
using it.
If you are using these instructions note that you will be getting
incorrect results.
