Thanks, this is almost there now. It was only the problem with the new
version of the move pattern (see below) that stopped this from being
"OK with...". The next round should be a formality though.

Hi Richard,
I've attached an example patch for the add pattern that tries to identify the
short microMIPS variants. In your last review, you mentioned that you would
like to see the register requirements modeled in the patterns. Do you have any
comments on the approach that I'm taking? Thanks

Hmm, to be honest, I'd rather you kept it local to the Mentor toolchain.

Hi Catherine,
Thanks for the update. Despite the length of this reply, there isn't

Please don't change all NOMIPS16 to NOCOMPRESSION in the testsuite.
Most NOMIPSs are there because of the drastically reduced MIPS16
instruction set. I would have expected most of them to pass wit
