Sure did (and in this particular case, as did colleagues in the course 
of development discussions) :)

First thing I will ask is this: Did you remember to regenerate the 
opcodes/aarch64-(asm|dis|opc)-2.c files??

If you're seeing a *lot* of new failures (easily in the order of the 
hundreds), then I'm betting good money that this might be to blame.

Please let me know if you continue face any issues!

Best regards,
Victor
