I disagree, the changes appear to be mostly my work, but with your name
at the top.
There are tell-tale identical comments and the mistake I made with
rorx/rory is there too.

You patch does not appear to include support for the new extended modes
of some of the S12X opcodes in tc-m68hc11.c (movb,movw,sex)

I haven't reviewed it any further than that.

James

PS. I thought we had agreed that we would collaborate and you would help
test my XGATE patches instead of submitting 'rival' work?
