Sure, that's one of still missing pieces.  To recap, I
consider the current patch set "feature complete" in the
sense that now the test suite passes and bootstrap works
using the asm parser; but it is still not yet ready to submit
for mainline inclusion.

What still needs to be done to get there AFAICS:
- Agree on the common code TableGen changes, in particular
  as they affect the ARM back-end.
- Agree on solutions for some of the still controversial
  PowerPC back-end patches (e.g. pre-inc).
- Some solution to the 64-bit vs. 32-bit issue.  [ One choice
  could be to ignore the problem for now, since it doesn't
  actually matter as long as the asm parser is solely used
  in the context of an assembler. ]
- Make sure errors are handled gracefully in the parser.
- Add test cases.


Bye,
Ulrich
