> This seems fixable. The custom parsers that are only valid for certain sub targets could easily have an explicit early-exit if the active sub target isn't what it's looking for. Would that be sufficient here?

It doesn't look like there are different encodings for the same string
so I don't think even that would be necessary. How about partitioning
by MRS_APSR and MRS_OtherM instead of the current MRS_M and MRS_AR?

I'll see if I can put a patch together.
