[LLVMdev] Help with subtarget features and context-dependent asm parsers
...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.
Tim.

Thanks, sounds like it might be more acceptable than I thought :-)
