Doing a target implementation based on the gdb/binutils
patches and not the actual documentation is going to be
enormously painful to review (to the point that I will almost
certainly just say "sorry, no"), because it will basically
be "you have the semantics of this wrong", "you have the
decoding wrong" all the way through for a whole pile of
corner cases. You need to be working from the actual ARM
documentation (which I regret is currently only available
under NDA).
See also the patchset that Alex Graf posted recently (which
is a bunch of framework code but not the actual decoder).
